Description

Wearable acoustic device

Technical Field

The present disclosure relates to the field of acoustic technologies, and in particular, to a wearable acoustic device.

Background

A hearing aid may be regarded as a small loudspeaker. In the case of hearing impaired users (hearing impaired or degraded users), the hearing aid may amplify sounds that the user would not have heard and deliver the sounds to the brain auditory center using the user's residual hearing, thereby allowing the user to hear the sounds. It follows that the hearing aid may compensate for the residual hearing of the user to improve the hearing of the user.

In real life there are some users who are monaural hearing impaired, i.e. users where one of the ears is substantially normal and the other is severely hearing impaired (there is substantially no residual hearing), e.g. the ear may reach severe to extremely severe sensorineural hearing loss, even deafness. For this type of user, the hearing loss on the weak ear (poor ear) side is too serious, and the conventional hearing aid cannot compensate for the hearing on the weak ear (poor ear) side. Thus, this type of user can only listen to sound with one normal ear. However, there is a head shadow effect on the head of the user, and sound emitted from a sound source close to the weak ear (bad ear) of the user may not be transferred to the normal ear (or even to the normal ear, there is a large attenuation) due to the head shielding, resulting in that the normal ear of the user cannot hear (or accurately hear) the sound on the weak ear (bad ear) side.

The statements in this background section merely provide information to the inventors and may not represent prior art to the present disclosure nor may they represent prior art to the filing date of the present disclosure.

Detailed Description

The following description is presented to enable one of ordinary skill in the art to make and use the invention, and is provided in the context of a particular application and its requirements. Various modifications to the disclosed embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments and applications without departing from the spirit and scope of the disclosure. Thus, the present description is not limited to the embodiments shown, but is to be accorded the widest scope consistent with the claims.

The terminology used herein is for the purpose of describing particular example embodiments only and is not intended to be limiting. For example, as used herein, the singular forms "a", "an" and "the" include plural referents unless the context clearly dictates otherwise. The terms "comprises," "comprising," "includes," and/or "including," when used in this specification, are taken to specify the presence of stated integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.

These and other features of the present specification, as well as the operation and function of the related elements of structure, as well as the combination of parts and economies of manufacture, may be significantly improved upon in view of the following description. All of which form a part of this specification, reference is made to the accompanying drawings. It is to be expressly understood, however, that the drawings are for the purpose of illustration and description only and are not intended as a definition of the limits of the description. It should also be understood that the drawings are not drawn to scale.

In the present embodiment, the use of prefix words such as "first", "second", etc. is only for convenience of distinguishing and describing different things that belong to the same name class, and does not restrict the order or number of things. For example, the "first information" and the "second information" are merely information of different contents or purposes, and have no time-sequence relationship or priority relationship, and the first information may be one information or a plurality of information, and the second information may also be one information or a plurality of information.

In the present description embodiments, "at least one" means one or more, and "a plurality" means two or more. "and/or" describes an association relationship of association objects, meaning that there may be three relationships, for example, a and/or B, and may represent three cases: a alone; both A and B are present; b alone; wherein A, B may be singular or plural. The character "/" generally indicates that the context-dependent object is an "or" relationship. "at least one of" or the like means any combination of these items, including any combination of single item(s) or plural items(s). For example, at least one (one) of a, b, or c may represent: a, a; b; c, performing operation; a and b; a and c; b and c; or a and b and c. Wherein a, b and c can be single or multiple.

For convenience of description, the present specification first explains terms in the following description as follows:

A monaural hearing impaired user refers to a user whose individual ears are hearing impaired, i.e., one of the user's ears is normally (or substantially normally) hearing while the other ear is severely impaired (or has little residual hearing). For example, a severely or even extremely severe sensorineural hearing loss, or even deafness (hearing loss), may be reached in the hearing-impaired ear. For convenience of description, in this specification, an ear of a hearing impaired user having normal (or substantially normal) hearing is referred to as "normal ear", and an ear having severely impaired hearing is referred to as "weak ear (or poor ear)".

It should be noted that the present application is not limited to the type of hearing impairment (specifically, which ear is weak) of the monaural hearing impaired user. For example, the left ear is a normal ear and the right ear is a weak ear; or the right ear is a normal ear and the left ear is a weak ear. In addition, the cause of the formation of the monaural hearing barrier is not limited in the present application. For example, it may be a monaural hearing impairment due to pathological causes, or a monaural hearing impairment due to external environmental causes. For example, the left ear is temporarily hearing impaired by being shocked in the explosion sound, or the environment on the left ear side is too noisy to effectively separate certain frequency components in the noise, etc.

Hearing level: is a measure of sound intensity common in audiology. By performing experiments on a group of 18-25 years old otology examination normal young people, the average value of the minimum sound pressure levels heard by the people at each frequency is set to be 0dB HL, and the average value is used as a reference value of pure-tone audiometry, namely the hearing zero level. The difference between the subject's threshold at each frequency and the reference value is expressed as a hearing level on a pure audiogram. The sensitivity of different persons to sound may be different, and some persons can hear sound below 0dB HL (which is better than the aforementioned reference value), and some persons cannot hear sound of 0dB HL but have hearing in a normal range.

Head shadow effect: when a sound source is located on one side (e.g., left or right) of the human head, the human head attenuates the sound emitted by the sound source as it passes from one side of the human head to the ear on the other side. This attenuation of sound by the human skull is known as the "head shadow effect".

The acoustic device provided in the present specification is a wearable acoustic device. The acoustic device may be worn on the head of the target user to improve the sound hearing of the target user. In particular, the acoustic device may be worn on the head of a monaural hearing impaired user to improve the listening effect of the monaural hearing impaired user to weak ear side sounds. Specifically, in the case where the monaural hearing-impaired user wears the acoustic device provided in the present specification, the acoustic device can collect the ambient sound on the weak ear side and deliver the ambient sound on the weak ear side to the normal ear, so that the normal ear can listen to the ambient sound on the weak ear side, thereby improving the listening effect of the monaural hearing-impaired user to the ambient sound on the weak ear side. Further, the acoustic device can openly convey the ambient sound on the weak ear side to the normal ear, so that the normal ear can simultaneously listen to the ambient sound on the weak ear side and the ambient sound on the normal ear side, thereby improving the overall hearing effect of the target user.

The acoustic device provided in the present specification is described in detail below with reference to the accompanying drawings.

Fig. 1 shows a schematic diagram of an acoustic device 100 provided according to an embodiment of the present description. Referring to fig. 1, an acoustic device 100 is an acoustic device that can be worn on the head of a target user (w/o). For example, the acoustic device 100 may be worn in a position near both ears of the target user. The target user may be a monaural hearing impaired user. For convenience of description, the left ear hearing of the target user is normal (or substantially normal), and the right ear hearing is severely impaired are illustrated in the drawings. That is, the left ear of the target user serves as a normal ear 010 and the right ear serves as a weak ear 020.

Wherein the weak ear 020 is different from the normal ear 010 in terms of the ability to hear ambient sound. The ability of the weak ear 020 to hear environmental sounds is weaker than the ability of the normal ear 010 to hear environmental sounds. For example, assume that a first sound source is present on the weak ear 020 side and a second sound source is present on the normal ear 010 side. The ability of the weak ear 020 to hear sound from the first sound source is weaker than the ability of the normal ear 010 to hear sound from the second sound source. For example, if the first sound source and the second sound source emit the same intensity of sound at the same time, the weak ear 020 cannot hear or can hear the sound emitted by the first sound source very weakly, and the normal ear 010 can hear the sound emitted by the second sound source normally. That is, the sound volume of the second sound source heard by the normal ear 010 is much larger than that of the first sound source heard by the weak ear 020.

The acoustic device 100 may include a base, a pickup module, and a sound emitting module. The base may also be referred to as a support, and refers to a component that supports, carries, or accommodates a component in the acoustic device 100 (e.g., a component in a pickup module, a component in a sound emitting module, etc.). The base is not shown in fig. 1. The base is configured to be wearable on the head of a target user. Those skilled in the art will understand that the base may be designed into various forms, and the specific form of the base is not limited in the present application, and the form of the base will be illustrated in conjunction with fig. 3A and 3B, which will not be described herein.

The pickup module refers to a module/module having a pickup function. The pickup module may include one or more pickup assemblies 110. Only the case where the sound pickup module includes one sound pickup assembly 110 is shown in fig. 1. Each pickup assembly 110 is operative to pick up ambient sound and convert the ambient sound into an electrical signal. The pickup assembly 110 may include a sound sensor. The sound sensor is a device for picking up ambient sound and converting the ambient sound into an electrical signal, which may also be referred to as an electroacoustic transducer. For example, the sound sensor may be a Microphone (MIC). In some embodiments, the number of sound sensors included in the pickup assembly 110 may be plural, and the plurality of sound sensors may be arranged in an array to achieve a directional pickup effect. In some embodiments, the pickup assembly may also include peripheral circuitry that may perform some processing of the electrical signals picked up by the sound sensor. The peripheral circuitry may include at least one circuit element that may include, but is not limited to, power amplification devices, operational amplification devices, analog-to-digital conversion devices, filtering devices, modulation devices, demodulation devices, capacitors, resistors, inductors, chips, and the like.

The pronunciation module refers to a module/module with pronunciation function. The pronunciation module may include one or more pronunciation components 120. Only the case where the pronunciation module includes one pronunciation component 120 is shown in fig. 1. Each sounding component can receive the electric signal and convert the electric signal into sound to be played. Pronunciation assembly 120 may include a speaker. A speaker is a device for converting an electrical signal (i.e., a driving signal) into sound, and may also be referred to as an electroacoustic transducer. For example, the speaker may be a horn (speaker). The speaker may be a device that emits sound based on at least one of a gas, a liquid, and a solid, which is not limited by the embodiment of the present specification. In some embodiments, the number of speakers included in the sound generating assembly 120 may be plural, and the plural speakers may be arranged in an array form to achieve a stereo playing effect. In some embodiments, the pronunciation component 120 may also include peripheral circuitry. The peripheral circuitry may be located at the input of the speaker. The peripheral circuitry may perform some processing on the electrical signal so that the processed electrical signal is suitable for playback by the speaker. The peripheral circuitry may include at least one circuit element that may include, but is not limited to, power amplification devices, operational amplification devices, analog-to-digital conversion devices, filtering devices, modulation devices, demodulation devices, capacitors, resistors, inductors, chips, and the like.

It is assumed that the two ears of the target user are referred to as a first ear and a second ear, respectively. The weak ear 020 may be one of the first ear or the second ear, and the normal ear 010 may be the other of the first ear or the second ear. With continued reference to fig. 1, the present description provides an acoustic device 100 in which the mount may include a first position corresponding to a first ear and a second position corresponding to a second ear. That is, the first location is located near the first ear and the second location is located near the second ear. The first and second positions are for mounting pickup assembly 110 and/or sound emitting assembly 120. For convenience of description and understanding later, the present specification refers to a position corresponding to the weak ear 020 among the first position and the second position as a sounding position (detection location), and a position corresponding to the normal ear 010 as a sound-out position (sound-out position). That is, the sounding location on the base may be located near the weak ear 020 and the sounding location may be located near the normal ear 010.

Referring to fig. 1, a pickup module includes at least a target pickup assembly 110. The target pickup assembly 110 is at least partially mounted in the sounding position of the base. For example, a sound sensor in the target pickup assembly 110 may be mounted at the sounding location. Since the sounding position corresponds to the weak ear 020, the target sound pickup assembly 110 is located near the weak ear 020 of the target user when the acoustic device 100 is worn on the head of the target user. Thus, the target sound pickup assembly 110 may be operated to pick up and convert ambient sound at the sound measurement location (i.e., near the weak ear 020) into an electrical signal. For convenience of description, the present specification refers to the environmental sound at the sounding position as the measured environmental sound v, and refers to the converted electrical signal as the target environmental signal y. That is, the target sound pickup assembly 110 operates to convert the measured ambient sound v at the sound measurement position (i.e., near the weak ear 020) into the target ambient signal y.

The pronunciation module includes at least a target pronunciation component 120. The target sound emitting assembly 120 may be communicatively coupled to the target pickup assembly 110. The target sound emitting component 120 is operative to obtain a target driving signal u corresponding to the target ambient signal y and to convert the target driving signal u into a target sound. The target driving signal u may refer to an electrical signal after the target environmental signal y is transmitted through a preset path. The preset path may refer to a signal transmission path corresponding to the communication connection between the target sound emitting component 120 and the target sound pickup component 110. For example, referring to fig. 1, when the target sound emitting assembly 120 and the target sound pickup assembly 110 are electrically connected, the predetermined path may be a signal transmission path corresponding to the electrical connection. The target drive signal u is identical to the audio content carried in the target ambient signal y. The target sound producing component 120 converts the target drive signal u into a target sound, which can be regarded as a sound reproduction result of the ambient sound on the weak ear 020 side by the target sound producing component 120.

With continued reference to FIG. 1, the target sound emitting assembly 120 is at least partially mounted in the sound emitting position of the base. For example, a speaker in target sound producing assembly 120 may be mounted at the sound producing location of the base. Since the sound emitting position corresponds to the normal ear 010, the target sound emitting component 120 is located near the normal ear 010 of the target user when the acoustic device 100 is worn on the head of the target user. Thus, the target sound emitting component 120 can deliver the target sound to the normal ear 010 after converting the target driving signal u into the target sound, so that the normal ear 010 can hear the target sound. As described above, since the target sound can be regarded as a sound reproduction result of the ambient sound on the weak ear 020 side by the target sound producing module 120, the target user can hear the ambient sound on the weak ear 020 side through the normal ear 010. It follows that the acoustic device 100 achieves the effect of listening to the ambient sound on the weak ear 020 side through the normal ear 010.

Further, the target sound emitting component 120 may openly deliver the target sound to the normal ear 010 after converting the target driving signal u into the target sound. Here, "open" means that the target sound emitting component 120 does not block the ear canal of the normal ear 010, i.e., the normal ear 010 can normally listen to the ambient sound at the sound emitting position (i.e., near the normal ear 010) in addition to the target sound emitted by the target sound emitting component 120. In order to distinguish from the measured ambient sound at the pick-up location (i.e., near the weak ear 020), the ambient sound at the sound-emitting location is referred to as a natural ambient sound in this specification. The natural environmental sound refers to sound emitted from a sound source on the side of the normal ear 010, including but not limited to environmental noise, human speech sound, music sound, and the like. Since the target sound emitting component 120 can openly deliver the target sound to the normal ear 010, the target sound emitting component 120 does not affect the listening of the natural environmental sound by the normal ear 010. That is, the normal ear 010 can listen to the target sound and the natural environmental sound at the sound emitting position at the same time, ensuring that the normal ear 010 has a good sound listening feel.

In some embodiments, the target pronunciation component 120 may employ a pronunciation component based on bone conduction. When the acoustic device 100 is worn on the head of the target user, the target sound component 120 may be located at the temporal bone on the same side of the normal ear 010 of the target user. In this way, the target sound emitting component 120 does not occlude the ear canal of the normal ear 010, thereby enabling an open delivery of the target sound to the normal ear 010.

In some embodiments, the target pronunciation component 120 may employ a pronunciation component based on air conduction. When the acoustic device 100 is worn on the head of the target user, an open acoustic space is formed between the target sound emitting assembly 120 and the eardrum of the normal ear 010. For example, the target sound component 120 may be located near the meatus of a normal ear 010 without occluding the meatus. In this way, the target sound emitting component 120 can achieve an open delivery of the target sound to the normal ear 010.

As mentioned above, in the acoustic device 100 provided in the present specification, the target sound emitting assembly 120 and the target sound pickup assembly 110 may be communicatively connected. The present application is not limited to the communication connection method between the two. For example, the communication connection may comprise a wired connection or a wireless connection. The wired connection may include electrical connection or connection by other wired means. The wireless connection may include connection by near magnetic field induction technology, or by other wireless means.

In some embodiments, the target sound emitting component 120 emits the target sound at a second time, assuming that the target sound pickup component 110 picks up the measured ambient sound at the first time. The target pickup assembly 110 and the target sound emitting assembly 120 are connected by the above-mentioned wired connection or wireless connection, so that the time delay between the second time and the first time is less than 10 ms. That is, the time delay between the second moment and the first moment is smaller, so that the listening time delay of the normal ear 010 to the ambient sound on the weak ear 020 side can be reduced, and the sound listening feeling of the user can be improved.

Fig. 1 illustrates an example of wired electrical connection between the target sound emitting assembly 120 and the target sound pickup assembly 110. Referring to fig. 1, the articulation module may also include a signal processing circuit 150. The signal processing circuit 150 may be a circuit having a certain signal processing capability. The target sound emitting assembly 120 and the target sound pickup assembly 110 may be electrically connected through the signal processing circuit 150. Specifically, the signal processing circuit 150 has an input terminal connected to the target sound pickup assembly 110 and an output terminal connected to the target sound producing assembly 120. The signal processing circuit 150 may obtain the target environmental signal y from the target pickup assembly 110 and perform a target operation on the target environmental signal y to obtain the target drive signal u. Further, the signal processing circuit transmits the target driving signal u to the target sound emitting component 120, thereby driving the target sound emitting component 120 to emit the target sound.

Wherein the target operation may include a zero term, one term, or multiple signal processing operations. When the target signal includes a zero signal processing operation, it is equivalent to the signal processing circuit 150 not performing any processing on the target environmental signal y, but directly transmitting it as the target driving signal u to the target sound generating component 120. When the target signal comprises one or more signal processing operations, the one or more signal processing operations may comprise signal amplification operations. That is, the signal processing circuit 150 may amplify the target environmental signal y by a target multiple to ensure that the target user has a good listening effect on the target sound.

In some embodiments, the signal processing circuit 150 may determine the amplification of the target ambient signal y on the principle that the hearing level of the sound emitted by the target sound emitting assembly 120 is consistent with the hearing level of the sound picked up by the target sound pickup assembly 110. That is, the signal processing circuit 150 amplifies the target environmental signal y by a target multiple so that the hearing level of the sound emitted from the target sound emitting component 120 coincides with the hearing level of the sound picked up by the target sound pickup component 110. By ensuring that "the hearing level of the sound emitted from the target sound emitting component 120 is identical to the hearing level of the sound picked up by the target sound pickup component 110", the listening effect of the target user to the environmental sound on the weak ear 020 side can be made more realistic.

For example, assume that target sound pickup assembly 110 is an air conduction-based sound pickup assembly and target sound pickup assembly 120 is a bone conduction-based sound pickup assembly. The target pickup assembly 110 picks up the air-guide sound and the target sound emitting assembly 120 emits the bone-guide sound. In general, the units of two physical quantities, i.e., the air-guide sound and the bone-guide sound, are different. In this case, the two physical quantities may be converted into hearing levels (in dBHL) respectively according to the reference equivalent threshold zero level. And then determining the target multiple according to the two converted physical quantities. For example, assuming that the signal amplitude of the sound picked up by the target sound pickup assembly 110 is AdBHL and the signal amplitude of the sound emitted by the target sound emitting assembly 120 is BdBHL, the signal processing circuit 150 may determine the target multiple G such that a=b. That is, the target multiple may be determined according to the principle that the reference domain of the bone conduction sound in the different frequency bands is aligned with the reference domain of the air conduction sound in the corresponding frequency band. It can be understood that this way can make the bone conduction volume heard by the normal ear 010 the same as or close to the volume of the real environment sound on the weak ear 020 side, thereby improving the sound hearing feeling of the user.

In practice, it has been found based on measurements of the "head shadow effect" that the attenuation of low frequency signals (e.g. signals of 250-500 Hz) by the skull is small and the attenuation of high frequency signals (e.g. signals of 500-8000 Hz) is large when sound propagates through the skull. Fig. 2 shows a schematic diagram of the "head shadow effect". It is assumed that a sound source x exists on the weak ear 020 side of the target user, and sound emitted by the sound source x is transmitted to the normal ear 010 through the skull. The attenuation of the sound intensity from the sound source x, which is heard by the normal ear 010, with respect to the original sound intensity emitted from the sound source x without wearing any hearing aid device by the target user is shown as a broken line in fig. 2. As can be seen in FIG. 2, the skull does not attenuate or attenuates less (less than 10 dB) the low frequency signals (e.g., 250-500Hz signals) in the sound, while attenuates more (10-25 dB) the high frequency signals (e.g., 500-8000Hz signals) in the sound.

It can be seen that the normal ear 010 of the target user can hear the low frequency component of the sound emitted from the sound source x on the weak ear 020 side (or, the normal ear 010 has a good effect of listening to the low frequency component), but cannot hear the high frequency component of the sound emitted from the sound source x (or, the normal ear 010 has a poor effect of listening to the high frequency component), without any acoustic device.

Based on the above analysis, in some embodiments, the signal processing circuit 150 may amplify signals of different frequency bands by different multiples when performing a signal amplifying operation on the target environmental signal y. It is assumed that the target ambient signal y comprises a signal component of the first frequency band and a signal component of the second frequency band. The first frequency band is a low frequency band (i.e., the frequency in the first frequency band is less than or equal to a preset frequency), and the second frequency band is a high frequency band (i.e., the frequency in the second frequency band is greater than the preset frequency). Then, the signal processing circuit 150 may perform different amplification factors on the signal components of the first frequency band and the signal components of the second frequency band based on the degree of influence of the "projection effect" on the first frequency band and the second frequency band. For example, the magnification corresponding to the first frequency band may be smaller than the magnification corresponding to the second frequency band. That is, assuming that the preset frequency is 500Hz, the magnification corresponding to 0-500Hz is smaller, or the magnification corresponding to 250-500Hz is smaller, than the magnification corresponding to 500-8000 Hz.

In some embodiments, the amplification factor determined by the signal processing circuit 150 may be zero or 1 for signal components of the first frequency band (e.g., 250-500Hz signal components). When the amplification factor is zero, the signal component of the first frequency band in the target environment signal y is discarded; when the amplification factor is 1, the signal component corresponding to the first frequency band in the target environment signal y is not amplified. As will be appreciated by those skilled in the art, since the attenuation of the low frequency signal by the skull is small, the normal ear 010 of the target user may also hear the low frequency component of the ambient sound on the weak ear 020 side normally without the aid of an acoustic device, and thus the signal processing circuit 150 determines the amplification factor of the low frequency component to be zero or 1, neither will affect the hearing of the normal ear 010 to the low frequency component in the ambient sound on the weak ear 020 side.

The amplification factor determined by the signal processing circuit 150 may be greater than 1 for signal components of the second frequency band (e.g., 500-8000 Hz). For example, the signal processing circuit 150 may determine the amplification factor G corresponding to the signal component of the second frequency band according to the principle that "the hearing level of the sound emitted by the target sound emitting component 120 is identical to the hearing level of the sound picked up by the target sound pickup component 110". Specific determination modes are described in the foregoing, and are not repeated here.

It can be understood that, when the signal processing circuit 150 amplifies the target environmental signal y, different amplification factors are executed for different frequency bands based on the influence degree of the head shadow effect on the different frequency bands, so that the target sound emitted by the target sounding component 120 can more truly restore the environmental sound on the weak ear 020 side, and the sound hearing of the normal ear 010 of the target user on the environmental sound on the weak ear 020 side is improved.

In some embodiments, acoustic device 100 may take the form of an earhook+posthanging product. The product form of the acoustic device 100 is illustrated below in conjunction with fig. 3A and 3B.

Fig. 3A and 3B show a schematic structural view of an acoustic device provided according to an embodiment of the present specification.

Wherein fig. 3A shows a front view of the acoustic device 100 and fig. 3B shows a rear view of the acoustic device 100. As shown in fig. 3A and 3B, the base of acoustic device 100 may include a first ear-hook component 320-a, a second ear-hook component 320-B, and a back-hook component 310. Wherein the first ear-hook component 320-a is hung from a first ear and the second ear-hook component 320-B is hung from a second ear when the acoustic device 300 is worn on the head of the target user. Rear suspension assembly 310 connects first and second ear-suspension assemblies 320-A and 320-B and is positioned behind the neck of the target user such that first and second ear-suspension assemblies 320-A and 320-B can be stably suspended over the ears.

Referring to fig. 3A and 3B, a first ear-hook assembly 320-a can include a first housing 321-a, a second housing 322-a, and a connector 323-a. The connection 323-a connects the first housing 321-a and the second housing 322-a. When the acoustic device 100 is worn on the head of the target user, the first housing 321-a is positioned in the auricle of the first ear of the target user or on the front side of the first ear, the second housing 322-a is positioned on the rear side of the first ear, and the connection 323-a is hung on the upper side of the first ear. The first casing 321-a and the second casing 322-a are respectively surrounded and formed with a receiving cavity. The two chambers may house components inside the acoustic device 100, such as a sound emitting assembly, a sound pickup assembly, a processing chip, a battery assembly, etc.

The second ear-hook assembly 320-B can include a first housing 321-B, a second housing 322-B, and a connector 323-B. The connection 323-B connects the first housing 321-B and the second housing 322-B. When the acoustic device 100 is worn on the head of the target user, the first housing 321-B is positioned in the auricle of the second ear of the target user or on the front side of the second ear, the second housing 322-B is positioned on the rear side of the second ear, and the connection 323-B is hung on the upper side of the second ear. The first casing 321-B and the second casing 322-B are respectively surrounded and formed with a receiving cavity. The two chambers may house components inside the acoustic device 100, such as a sound emitting assembly, a sound pickup assembly, a processing chip, a battery assembly, etc.

Based on the product morphology shown in fig. 3A and 3B, the target sound component 120 can be disposed on the second ear-hook component 320-B. Specifically, the target sound emitting assembly 120 may be positioned within a receiving cavity formed by the first housing 321-B of the second ear-hook assembly 320-B. Thus, when the target sound emitting assembly 120 emits sound, the sound is delivered to the second ear, and thus, the second ear of the target user hears the sound.

For example, the target pronunciation component 120 may employ a bone conduction based pronunciation component. In this case, the target sound emitting assembly 120 includes at least a vibrating portion. The target sounding assembly 120 is located in the accommodating cavity formed by the first casing 321-B, and at least part of the surface of the first casing 321-B is attached to the vibration part. When the acoustic device 100 is worn on the head of the target user, the at least part of the surface of the first housing 321-B is in contact with the skin at the temporal bone on the front side of the second ear of the target user. Thus, the vibration waves generated by the vibration portion can be transmitted through the temporal bone so that the target user "hears" the sound emitted by the target sound emitting assembly 120 through the second ear.

As another example, the target pronunciation component 120 may employ a pronunciation component based on air conduction. In this case, the first casing 321-B is provided with a sound outlet, and the target sounding component 120 is located in the accommodating cavity formed by the first casing 321-B and corresponds to the sound outlet. When the acoustic device 300 is worn on the head of the target user, the first housing 321-B is positioned within the pinna of the second ear and does not occlude the meatus. The sound outlet is positioned close to the auditory meatus. The sound waves emitted by the target sound emitting component 120 are transmitted into the auditory canal of the second ear through the sound emitting hole, so that the target user hears the sound.

The target pickup assembly 110 may be disposed on the first ear-hook assembly 320-a. Specifically, the target pickup assembly 110 may be positioned within a receiving cavity formed by the first housing 321-a or the second housing 322-a of the first ear-hook assembly 320-a.

For example, fig. 3A shows the target pickup assembly 110 positioned within the receiving cavity formed by the first housing 321-a. Referring to fig. 3A, a first pickup port 324-a may be provided on the first housing 321-a. The target pickup assembly 110 may be positioned in a receiving chamber formed by the first housing 321-a and corresponds to the first pickup port 324-a. The target sound pickup assembly 110 may pick up ambient sound near the first ear through the first sound pickup opening 324-a. In some embodiments, when acoustic device 100 is worn on the head of the target user, the distance between first pickup opening 324-a and the ear canal opening of the first ear of the target user is less than or equal to d, which is the average distance between points on the non-skin-engaging surface of first housing 321-a and the ear canal opening. In some embodiments, the value of d may be 5 millimeters, that is, the distance between the first pickup opening 324-a and the ear canal opening of the first ear of the target user is less than or equal to 5 millimeters when the acoustic device 100 is worn on the head of the target user. In some embodiments, the first pickup port 324-A is located closer to the ear canal opening. For example, the first sound pickup opening 324-a may be provided at a position closest to the ear canal opening on the surface of the first casing 321-a that is not in contact with the skin.

In the arrangement of the target sound pickup assembly 110 shown in fig. 3A, when the first sound pickup opening 324-a is closer to the ear canal opening (i.e., the target sound pickup assembly 110 is closer to the ear canal opening), the amplitude phase information of the sound picked up by the target sound pickup assembly 110 is closer to the sound that the first ear should naturally receive. In this way, the sound emitted by the target sound emitting assembly 120 is more reduced to the sound picked up by the target sound pickup assembly 110. Thus, the target user obtains a more realistic hearing sensation. In addition, since the target sound emitting assembly 120 and the target sound pickup assembly 110 are respectively located at both sides of the head of the target user, the target sound emitting assembly 120 and the target sound pickup assembly 110 do not form self-excited oscillation, thereby avoiding howling generated by the acoustic device 100.

For another example, fig. 3B shows the target pickup assembly 110 positioned within the receiving cavity formed by the second housing 322-a. Referring to fig. 3B, a second pickup port 325-a may be provided on the target surface of the second housing 322-a. Wherein the target surfaces may include a rear side surface and an outer side surface of the second housing 322-a. The rear side surface means: the surface of the second housing 322-a facing the rear side of the user when the acoustic device 100 is worn on the head of the target user. The outer side surface means: the surface of the second housing 322-a that is remote from the user's head when the acoustic device 100 is worn on the head of the target user. The target pickup assembly 110 is disposed in the receiving cavity formed by the second housing 322-a and corresponds to the second pickup port 325-a. The target sound pickup assembly 110 picks up ambient sound near the first ear through the second sound pickup port 325-a. In fig. 3B, the second sound pickup port 325-a is illustrated as being provided on the rear side surface of the second housing 322-a.

The arrangement of the target pickup assembly 110 shown in fig. 3B facilitates compatibility design with existing products (e.g., pickup assemblies already deployed within the second housing 322-a of the existing product) on the premise that the target pickup assembly 110 is capable of picking up ambient sound near the first ear. In addition, since the target sound emitting assembly 120 and the target sound pickup assembly 110 are respectively located at both sides of the head of the target user, the target sound emitting assembly 120 and the target sound pickup assembly 110 do not form self-excited oscillation, thereby avoiding howling generated by the acoustic device 100.

Based on the product form shown in fig. 3A and 3B, the signal processing circuit 150 and the battery assembly may be disposed in the accommodating cavity formed by the second housing 322-a and the second housing 322-B, respectively, so as to help maintain the balance of the acoustic device 100 and improve the wearing stability. For example, in some embodiments, the signal processing circuit 150 may be located within a cavity formed by the second housing 322-A, and the battery assembly may be located within a cavity formed by the second housing 322-B. For another example, in some embodiments, the signal processing circuit 150 may be located within a receiving cavity formed by the second housing 322-B, and the battery assembly may be located within a receiving cavity formed by the second housing 322-A.

Further, the target pickup assembly 110, the signal processing circuit 150, and the target sound emitting assembly 120 are connected by wires, and the wires may be disposed in the rear hanging assembly 310.

As will be appreciated by those skilled in the art, when the target sound emitting assembly 120 is electrically connected to the target sound pickup assembly 110 (e.g., via a wire extending through the rear suspension assembly 310), the ambient sound on the weak ear 020 side picked up by the target sound pickup assembly 110 is transmitted to the target sound emitting assembly 120 in the form of an electrical signal through a circuit, and is converted into a target sound by the target sound emitting assembly 120 and transmitted to the normal ear 010. Because the transmission delay of the circuit transfer to the electric signal is smaller, that is, the delay between the time when the target sound emitting component 120 emits the target sound and the time when the target sound collecting component 110 picks up the measured environmental sound is smaller than 10 milliseconds, the above scheme can reduce the listening delay of the normal ear 010 to the environmental sound on the weak ear 020 side, thereby improving the listening effect of the target user to the environmental sound on the weak ear 020 side. In addition, in a relatively complex electromagnetic environment, the circuit transfer does not generate electromagnetic interference, so the scheme can also improve the anti-interference capability of the acoustic device 100 in the complex electromagnetic environment.

As can be seen from the summary, the acoustic apparatus 100 shown in fig. 1, when being worn on the head of a target user, picks up and converts the ambient sound on the weak ear 020 side of the target user into the target ambient signal y through the target sound pickup assembly 110, and converts the target driving signal u corresponding to the target ambient signal y into the target sound through the target sound emitting assembly 120 and openly transmits the target sound to the normal ear 010, thereby realizing the listening of the ambient sound on the weak ear 020 side through the normal ear 010, and improving the listening effect of the monaural hearing impaired user to the ambient sound on the weak ear 020 side. In addition, since the target sound producing component 120 is configured to deliver the target sound to the normal ear 010 in an open manner, the normal ear 010 will not influence the listening of the normal ear 010 to the ambient sound, that is, the normal ear 010 can listen to the ambient sound of the weak ear 020 side and the ambient sound of the normal ear 010 side at the same time, so that the overall hearing effect of the target user is improved.

Fig. 1 is illustrated with the pickup module including a pickup assembly 110 and the pronunciation module including a pronunciation assembly 120. While in some embodiments, the pickup module may include a plurality of pickup assemblies 110 and the pronunciation module may include a plurality of pronunciation assemblies 120. The details are described below in connection with fig. 4.

Fig. 4 shows a schematic diagram of another acoustic device provided according to an embodiment of the present description. The acoustic device 200 shown in fig. 4 includes a base, a pickup module, and a sound emitting module.

Referring to fig. 4, for convenience of description, the right ear of the target user is referred to as a first ear 040, and the left ear is referred to as a second ear 030. The base includes a first position corresponding to first ear 040 and a second position corresponding to second ear 030.

The pickup module includes a first pickup assembly 110-a and a second pickup assembly 110-B. Wherein the first pickup assembly 110-a is mounted in a first position and is operative to convert a first ambient sound v ₁ at the first position into a first ambient signal y ₁. The second pickup assembly 110-B is mounted in a second location and is operative to convert a second ambient sound v ₂ at the second location to a second ambient signal y ₂.

The pronunciation module includes a first pronunciation component 120-a and a second pronunciation component 120-B. Wherein the first sound emitting assembly 120-a is mounted in a second position on the base and is communicatively coupled to the first sound emitting assembly 110-a, and is operative to convert a first drive signal u ₁ corresponding to the first ambient signal y ₁ into a first sound and to deliver the first sound to the second ear 030 in an open manner. The second sound emitting assembly 120-B is mounted in the first position of the base and is communicatively coupled to the second sound pickup assembly 110-B, and is operative to convert a second drive signal u ₂ corresponding to the second ambient signal y ₂ into a second sound and to deliver the second sound to the first ear 040.

In the acoustic device 200 shown in fig. 4, the first sound pickup assembly 110-a and the first sound emitting assembly 120-a may cooperate, and the manner of cooperation thereof may be similar to that of the target sound pickup assembly 110 and the target sound emitting assembly 120 in fig. 1, and a detailed description thereof will be omitted. The acoustic device 200 works cooperatively through the first sound pickup assembly 110-a and the second sound emitting assembly 120-a so that the target user can listen to the ambient sound on the side of the first ear 040 and the ambient sound on the side of the second ear 030 through the second ear 030 at the same time. Therefore, when the first ear 040 of the target user is a weak ear and the second ear 030 is a normal ear, the target user can realize simultaneous listening to the ambient sound on the first ear 040 side and the ambient sound on the second ear 030 side through the second ear 030 by wearing the acoustic device 200 shown in fig. 4, thereby improving the sound listening feeling of the target user.

In the acoustic device 200 shown in fig. 4, the second sound pickup assembly 110-B and the second sound emitting assembly 120-B may cooperate, and the manner of cooperation thereof may be similar to that of the target sound pickup assembly 110 and the target sound emitting assembly 120 in fig. 1, and a detailed description thereof will be omitted. The acoustic device 200 works cooperatively through the second sound pickup assembly 110-B and the second sound emitting assembly 120-B so that the target user can listen to the ambient sound on the side of the first ear 040 and the ambient sound on the side of the second ear 030 through the first ear 040 at the same time. Therefore, when the first ear 040 of the target user is a normal ear and the second ear 030 is a weak ear, the target user can realize simultaneous listening to the ambient sound on the first ear 040 side and the ambient sound on the second ear 030 side through the first ear 040 by wearing the acoustic device 200 shown in fig. 4, thereby improving the sound listening feeling of the target user.

It follows that the acoustic device 200 shown in fig. 4 can be adapted to all monaural hearing impaired users, regardless of which ear the user is hearing impaired in particular. That is, the acoustic device 200 is applicable to users with severely impaired left ear hearing, and to users with severely impaired right ear hearing, and has wide applicability.

In some embodiments, the modes of operation of the acoustic device 200 shown in fig. 4 may include a first mode and a second mode.

Wherein the acoustic device 200 may operate in the first mode when the first ear 040 of the target user is a weak ear and the second ear 030 is a normal ear. At this time, the first sound pickup assembly 110-a and the first sound emitting assembly 120-a are operated cooperatively, and the second sound pickup assembly 110-B and the second sound emitting assembly 120-B are not operated.

The acoustic device 200 may operate in the second mode when the first ear 040 of the target user is a normal ear and the second ear 030 is a weak ear. At this time, the second sound pickup assembly 110-B and the second sound emitting assembly 120-B are operated cooperatively, while the first sound pickup assembly 110-a and the first sound emitting assembly 120-a are not operated.

It follows that the acoustic device 200 may be operated in different modes of operation for different types of monaural hearing impairment users, respectively. In this way, the acoustic device 200 can both meet the hearing aid needs of different types of monaural hearing impaired users and reduce overall power consumption.

In some embodiments, with continued reference to fig. 4, the articulation module of the acoustic device 200 may also include a signal processing circuit 150. The signal processing circuit 150 may be electrically connected to the first sound pickup assembly 110-a, the second sound pickup assembly 110-B, the first sound emitting assembly 120-a, and the second sound emitting assembly 120-B, respectively.

In the first mode, the signal processing circuit 150 may obtain the first ambient signal y ₁ from the first sound pickup assembly 110-a, perform a first target operation on the first ambient signal y ₁ to obtain the first driving signal u ₁, and transmit the first driving signal u ₁ to the first sound emitting assembly 120-a, thereby driving the first sound emitting assembly 120-a to emit the first sound. In some embodiments, in performing the first target operation, the signal processing circuit 150 may amplify the first ambient signal y ₁ by a first target multiple so that the level of hearing of the sound emitted by the first sound-emitting assembly 120-a corresponds to the level of hearing of the sound picked up by the first sound-emitting assembly 110-a. In some embodiments, the first ambient signal y ₁ may include a signal component of the first frequency band and a signal component of the second frequency band. The signal processing circuit 150 may perform different amplification factors on the signal component of the first frequency band and the signal component of the second frequency band when amplifying the first environment signal y ₁. For example, assuming that the frequency in the first frequency band is less than or equal to the preset frequency, and the frequency in the second frequency band is greater than the preset frequency, the signal processing circuit 150 may amplify the signal component of the first frequency band by zero or 1, and amplify the signal component of the second frequency band by more than 1.

Those skilled in the art will appreciate that the manner in which the signal processing circuit 150 performs the first target operation on the first environmental signal y ₁ is similar to the manner in which the signal processing circuit 150 performs the target operation on the target environmental signal y in fig. 1, and reference is made to the foregoing description, which is not repeated here.

In the second mode, the signal processing circuit 150 may obtain the second ambient signal y ₂ from the second pickup assembly 110-B, perform a second target operation on the second ambient signal y ₂ to obtain a second driving signal u ₂, and send the second driving signal u ₂ to the second sound emitting assembly 120-B, thereby driving the second sound emitting assembly 120-B to emit a second sound. In some embodiments, in performing the second target operation, the signal processing circuit 150 may amplify the second ambient signal y ₂ by a second target multiple so that the level of hearing of the sound emitted by the second sound emitting assembly 120-B corresponds to the level of hearing of the sound picked up by the second sound pickup assembly 110-B. In some embodiments, the second ambient signal y ₂ may include a signal component of the first frequency band and a signal component of the second frequency band. The signal processing circuit 150 may perform different amplification factors on the signal component of the first frequency band and the signal component of the second frequency band when amplifying the second environment signal y ₂. For example, assuming that the frequency in the first frequency band is less than or equal to the preset frequency, and the frequency in the second frequency band is greater than the preset frequency, the signal processing circuit 150 may amplify the signal component of the first frequency band by zero or 1, and amplify the signal component of the second frequency band by more than 1.

Those skilled in the art will appreciate that the manner in which the signal processing circuit 150 performs the second target operation on the second environmental signal y ₂ is similar to the manner in which the signal processing circuit 150 performs the target operation on the target environmental signal y in fig. 1, and reference is made to the foregoing description, which is not repeated here.

In some embodiments, the signal processing circuit 150 may be configured to receive a control signal and control the acoustic device 200 to operate in the first mode or the second mode based on the control signal. Wherein the control signal characterizes the type of monaural hearing impairment of the target user, or, in other words, which specific ear of the target user is the weak ear. For example, the control signal may characterize the first ear 040 of the target user as a weak ear, at which point the signal processing circuit 150 controls the acoustic device 200 to operate in the first mode. For another example, the control signal may be indicative of the second ear 030 of the target user being a weak ear, at which point the signal processing circuitry 150 controls the acoustic device 200 to operate in the second mode.

Note that, the triggering manner of the control signal is not limited in this specification. For example, the control signal may be a signal sent by the target user to the acoustic device 200 via a control device (e.g., a cell phone communicatively coupled to the acoustic device 200). For another example, the control signal may also be a signal triggered by the target user by operating an operation control (e.g., button, touch control, etc.) provided on the acoustic device 200.

It follows that the target user may trigger a control signal to the acoustic device 200 according to the type of the own monaural hearing barrier (i.e. which ear is the weak ear), so that the acoustic device 200 selects to operate in the corresponding operation mode based on the control signal. When different users use the acoustic device 200, the working mode of the acoustic device 200 can be flexibly switched according to the situation, so that the application flexibility and convenience of the acoustic device 200 are improved.

The structure of the signal processing circuit 150 in the acoustic device 200 is illustrated below with reference to fig. 5 and 6.

Fig. 5 shows a schematic diagram of a configuration of the signal processing circuit 150 in fig. 4. As shown in fig. 5, the signal processing circuit 150 may include a first processing circuit 151 and a second processing circuit 152. Wherein the first processing circuit 151 is configured to perform a first mode and the second processing circuit 152 is configured to perform a second mode.

Referring to fig. 5, the first processing circuit 151 is electrically connected to the first pickup assembly 110-a and the first sound emitting assembly 120-a, respectively. In the first mode, the first processing circuit 151 obtains the first ambient signal y ₁ from the first sound pickup assembly 110-a, performs a first target operation on the first ambient signal y ₁ to obtain a first driving signal u ₁, and transmits the first driving signal u ₁ to the first sound emitting assembly 120-a, thereby driving the first sound emitting assembly 120-a to emit a first sound.

With continued reference to fig. 5, the second processing circuit 152 is electrically connected to the second pickup assembly 110-B and the second sound emitting assembly 120-B, respectively. In the second mode, the second processing circuit 152 obtains the second ambient signal y ₂ from the second pickup assembly 110-B, performs a second target operation on the second ambient signal y ₂ to obtain a second drive signal u ₂, and sends the second drive signal u ₂ to the second sound emitting assembly 120-B to thereby drive the second sound emitting assembly 120-B to emit a second sound.

In some embodiments, the first processing circuit 151 and the second processing circuit 152 may each correspond to a separate processing chip. For example, the first processing circuit 151 corresponds to the processing chip 1, and the second processing circuit 152 corresponds to the processing chip 2. In other embodiments, the first processing circuit 151 and the second processing circuit 152 may also respectively correspond to different processing units in the same processing chip.

In the signal processing circuit 150 shown in fig. 5, the first sound pickup assembly 110-a and the first sound emitting assembly 120-a are connected by the first processing circuit 151, so that a first signal transmission path is formed between the first sound pickup assembly 110-a and the first sound emitting assembly 120-a; the second pickup assembly 110-B and the second sound emitting assembly 120-B are connected by the second processing circuit 152 so that a second signal transmission path is formed between the second pickup assembly 110-B and the second sound emitting assembly 120-B. The two signal transmission paths are not interfered with each other. When the acoustic device 200 is operating in the first mode, the first processing circuit 151 is operating, while the second processing circuit 152 may be inactive; when the acoustic device 200 is operating in the second mode, the second processing circuit 152 is operating, while the first processing circuit 151 may not be operating. It can be seen that the signal processing circuit 150 shown in fig. 5 is simple in structure and easy to deploy. In addition, the signal transmission paths corresponding to the first mode and the second mode are independent, so that the signal transmission paths are not interfered with each other, and the operation stability of the signal processing circuit 150 is improved.

Fig. 6 shows another structural schematic diagram of the signal processing circuit 150 in fig. 4. As shown in fig. 6, the signal processing circuit 150 may include a third processing circuit 153, a first switching circuit 154, a second switching circuit 155, and a control circuit 156.

Wherein, referring to fig. 6, the first switching circuit 154 is connected with the third processing circuit 153, the first sound pickup assembly 110-a, and the second sound pickup assembly 110-B, respectively. The first switch circuit 154 has a selection function, and can selectively communicate the first sound pickup assembly 110-a with the third processing circuit 153 or selectively communicate the second sound pickup assembly 110-B with the third processing circuit 153. In fig. 6, the solid line in the first switch circuit 154 indicates communication, and the broken line indicates non-communication.

The second switching circuit 155 is connected to the third processing circuit 153, the first sounding component 120-a and the second sounding component 120-B, respectively. The second switch circuit 155 has a selection function and can selectively communicate the first sounding component 120-a with the third processing circuit 153 or selectively communicate the second sounding component 120-B with the third processing circuit 153. In fig. 6, the solid line in the second switching circuit 155 indicates communication, and the broken line indicates non-communication.

The first switching circuit 154 and the second switching circuit 155 may be implemented by switching elements. For example, in some embodiments, the first switching circuit 154 and the second switching circuit 155 may employ semiconductor devices (e.g., transistors, field effect transistors) as switching elements to control the switching state by controlling the voltage or current of the input signal. For another example, in some embodiments, the first switching circuit 154 and the second switching circuit 155 may employ Complementary Metal Oxide Semiconductor (CMOS) logic gates as switching elements. For another example, in some embodiments, the first switching circuit 154 and the second switching circuit 155 may also employ flip-flops as switching elements.

With continued reference to fig. 6, the control circuit 156 is coupled to the first switching circuit 154 and the second switching circuit 155. The control circuit 156 may control the first switching circuit 154 and the second switching circuit 155 based on the operating mode in which the acoustic device 200 is placed.

Specifically, when the acoustic apparatus 200 is operating in the first mode, the control circuit 156 controls the first switching circuit 154 to communicate the first sound pickup assembly 110-a and the third processing circuit 153, and controls the second switching circuit 155 to communicate the first sound pickup assembly 120-a and the third processing circuit 153. In this case, the third processing circuit 153 obtains the first environment signal y ₁ from the first sound pickup assembly 110-a, performs the first target operation on the first environment signal y ₁ to obtain the first driving signal u ₁, and transmits the first driving signal u ₁ to the first sound emitting assembly 120-a, thereby driving the first sound emitting assembly 120-a to emit the first sound.

When the acoustic device 200 is operating in the second mode, the control circuit 156 controls the first switching circuit 154 to communicate with the second sound pickup assembly 110-B and the third processing circuit 153, and controls the second switching circuit 155 to communicate with the second sound emitting assembly 120-B and the third processing circuit 153. In this case, the third processing circuit 153 obtains the second environmental signal y ₂ from the second sound pickup assembly 110-B, performs the second target operation on the second environmental signal y ₂ to obtain the second driving signal u ₂, and transmits the second driving signal u ₂ to the second sound emitting assembly 120-B, thereby driving the second sound emitting assembly 120-B to emit the second sound.

The signal processing circuit 150 shown in fig. 6 is configured by providing a first switching circuit 154 and a second switching circuit 155 such that: in the first mode, the third processing circuit 153 may communicate the first pickup assembly 110-A with the first sound emitting assembly 120-A, and in the second mode, the third processing circuit 153 may communicate the second pickup assembly 110-B with the second sound emitting assembly 120-B. It can be seen that the first mode and the second mode may share one processing circuit (i.e., the third processing circuit 153), so that only one processing chip (as the third processing circuit 153) needs to be provided in the acoustic device 200, which contributes to reducing hardware cost.

Fig. 7A and 7B show a schematic structural diagram of an acoustic device 200 provided according to an embodiment of the present specification.

Wherein fig. 7A shows a front view of the acoustic device 200 and fig. 7B shows a rear view of the acoustic device 200. As shown in fig. 7A and 7B, the base form of the acoustic device 200 is similar to the base form of the acoustic device 100 shown in fig. 3A and 3B, and will not be described in detail herein. The arrangement positions of the first sound pickup assembly 110-a, the second sound pickup assembly 110-B, the first sound emitting assembly 120-a, and the second sound emitting assembly 120-B are exemplified below with reference to fig. 7A and 7B.

The first sound emitting component 120-a may be located in a receiving cavity formed by the first housing 321-B of the second ear-hook component 320-B. Thus, when the first sound emitting component 120-a emits a first sound, the first sound is delivered to the second ear of the target user such that the second ear hears the first sound.

The second sound emitting assembly 120-B can be positioned within the receiving cavity formed by the first housing 321-a of the first ear-hook assembly 320-a. Thus, when the second sound emitting component 120-B emits a second sound, the second sound is delivered to the first ear of the target user such that the first ear hears the second sound.

It should be noted that, the first sounding component 120-a and the second sounding component 120-B may be bone conduction sounding components, or air conduction sounding components may be adopted, and specific arrangement modes may be described in the foregoing, which is not repeated herein.

In some embodiments, the first pickup assembly 110-A and the second pickup assembly 110-B may be configured as follows: the first pickup assembly 110-a is positioned in a receiving cavity formed by the first housing 321-a of the first ear-hook assembly 320-a, and the second pickup assembly 110-B is positioned in a receiving cavity formed by the first housing 321-B of the second ear-hook assembly 320-B.

As shown in connection with FIG. 7A, a first pickup port 324-A may be provided on the first housing 321-A of the first ear-hook assembly 320-A. The first pickup assembly 110-a may be located in a receiving cavity formed by the first housing 321-a and corresponds to the first pickup opening 324-a. Thus, the first sound pickup assembly 110-a can pick up ambient sound near the first ear through the first sound pickup opening 324-a. The second housing 321-B of the second ear-hook assembly 320-B may have a first sound pickup opening 324-B disposed thereon. The second pickup assembly 110-B may be located in a receiving cavity formed by the first housing 321-B and corresponds to the first pickup port 324-B. Thus, the second sound pickup assembly 110-B can pick up ambient sound near the second ear through the first sound pickup opening 324-B.

In some embodiments, when the acoustic device 200 is worn on the head of the target user, the distance between the first sound pickup opening 324-a and the ear canal opening of the first ear of the target user is less than or equal to d, which is the average distance between points on the surface of the first housing 321-a that is not skin-engaging and the ear canal opening. That is, the first sound pickup opening 324-a is located closer to the ear canal opening. For example, the first sound pickup opening 324-a may be provided at a position closest to the ear canal opening on the surface of the first casing 321-a that is not in contact with the skin. It should be noted that, the arrangement of the first sound pickup opening 324-B on the first housing 321-B is similar to the arrangement of the first sound pickup opening 324-a on the first housing 321-a, and will not be repeated here.

The arrangement of the first pickup assembly 110-a shown in fig. 7A is such that when the first pickup assembly 110-a is closer to the meatus of the ear (i.e., the first pickup port 324-a is closer to the meatus of the ear), the amplitude phase information of the sound picked up by the first pickup assembly 110-a is closer to the sound that the first ear should naturally receive. In this way, the sound emitted by the first sound emitting assembly 120-a is more reduced to the sound picked up by the first sound emitting assembly 110-a. Thus, the target user obtains a more realistic hearing sensation. In addition, since the first sound pickup assembly 110-a and the first sound emitting assembly 120-a are respectively located at both sides of the head of the target user, self-excitation vibration is not formed between the first sound pickup assembly 110-a and the first sound emitting assembly 120-a, thereby avoiding howling generated by the acoustic apparatus 200. Further, although the first sound pickup assembly 110-a and the second sound emitting assembly 120-B are both disposed in the receiving chamber formed by the first housing 321-a and both are close to the ear canal opening, since the acoustic device 200 is applied to a monaural hearing impaired user, the first sound pickup assembly 110-a and the second sound emitting assembly 120-B do not operate simultaneously (the first sound pickup assembly 110-a operates while the second sound emitting assembly 120-B does not operate in the first mode, and the second sound emitting assembly 120-B operates while the first sound pickup assembly 110-a does not operate in the second mode), and thus self-excitation vibration is not generated between the first sound pickup assembly 110-a and the second sound emitting assembly 120-B, thereby avoiding howling generated by the acoustic device 200.

The arrangement of the second pickup assembly 110-B shown in fig. 7A, when the second pickup assembly 110-B is closer to the ear canal opening (i.e., the first pickup opening 324-B is closer to the ear canal opening), the amplitude phase information of the sound picked up by the second pickup assembly 110-B is closer to the sound that the second ear should naturally receive. In this way, the sound emitted by the second sound emitting assembly 120-B is more reduced to the sound picked up by the second sound pickup assembly 110-B. Thus, the target user obtains a more realistic hearing sensation. In addition, since the second sound pickup assembly 110-B and the second sound emitting assembly 120-B are positioned at both sides of the head of the target user, respectively, no self-excitation oscillation is formed between the second sound pickup assembly 110-B and the second sound emitting assembly 120-B, thereby avoiding howling generated by the acoustic apparatus 200. Further, although the second sound pickup assembly 110-B and the first sound emitting assembly 120-a are both disposed in the receiving chamber formed by the second housing 321-B and both are close to the ear canal opening, since the acoustic device 200 is applied to a monaural hearing-impaired user, the second sound pickup assembly 110-B and the first sound emitting assembly 120-a do not operate simultaneously (the first sound emitting assembly 120-a operates and the second sound pickup assembly 110-B does not operate in the first mode, and the second sound pickup assembly 110-B does not operate and the first sound emitting assembly 120-a does not operate in the second mode), and thus self-excitation vibration is not formed between the second sound pickup assembly 110-B and the first sound emitting assembly 120-a, thereby avoiding howling generated by the acoustic device 200.

In some embodiments, the first pickup assembly 110-A and the second pickup assembly 110-B may also be configured as follows: the first pickup assembly 110-a is positioned in a receiving cavity formed by the second housing 322-a of the first ear-hook assembly 320-a, and the second pickup assembly 110-B is positioned in a receiving cavity formed by the second housing 322-B of the second ear-hook assembly 320-B.

As shown in connection with fig. 7B, a second pickup port 325-a may be provided on the target surface of the second housing 322-a of the first earhook assembly 320-a. Wherein the target surfaces may include a rear side surface and an outer side surface of the second housing 322-a. The rear side surface means: the surface of the second housing 322-a facing the rear side of the user when the acoustic device 200 is worn on the head of the target user. The outer side surface means: the surface of the second housing 322-a that is remote from the user's head when the acoustic device 200 is worn on the head of the target user. The first pickup assembly 110-a is disposed in the receiving cavity formed by the second housing 322-a and corresponds to the second pickup port 325-a. Thus, the first sound pickup assembly 110-a picks up the ambient sound near the first ear through the second sound pickup port 325-a. Fig. 7B illustrates an example in which the second sound pickup port 325-a is provided on the rear side surface of the second housing 322-a.

A second pickup port 325-B may be provided on a target surface of the second housing 322-B of the second ear-hook assembly 320-B. Wherein the target surfaces may include a rear side surface and an outer side surface of the second housing 322-B. The rear side surface means: the surface of the second housing 322-B facing the rear side of the user when the acoustic device 200 is worn on the head of the target user. The outer side surface means: when the acoustic device 200 is worn on the head of the target user, the surface of the second housing 322-B that is remote from the head of the user. The second pickup assembly 110-B is disposed in the receiving cavity formed by the second housing 322-B and corresponds to the second pickup port 325-B. Thus, the second sound pickup assembly 110-B picks up the ambient sound near the second ear through the second sound pickup port 325-B. Fig. 7B illustrates an example in which the second sound pickup port 325-B is provided on the rear side surface of the second housing 322-B.

The arrangement of the first pickup assembly 110-a and the second pickup assembly 110-B shown in fig. 7B facilitates compatibility designs with existing products (e.g., pickup assemblies already deployed within the second housing 322-a and the second housing 322-B of existing products) while ensuring that the first pickup assembly 110-a is capable of picking up ambient sound near the first ear and the second pickup assembly 110-B is capable of picking up ambient sound near the second ear. In addition, since the first sound pickup assembly 110-A is far from the second sound pickup assembly 120-B, self-excitation oscillation is not formed between the two; in addition, the second sound pickup assembly 110-B is far from the first sound emitting assembly 120-a, and no self-excitation oscillation is formed between the two, thereby avoiding howling generated by the acoustic device 200.

As can be seen from the summary, in the acoustic apparatus 200 shown in fig. 4, in the first mode, the first sound pickup assembly 110-a picks up and converts the environmental sound of the first ear 040 side of the target user into the first environmental signal y ₁, and the first sound pickup assembly 120-a converts the first driving signal u ₁ corresponding to the first environmental signal y ₁ into the first sound and delivers the first sound to the second ear 030 in an open manner, so that the first ear 040 side environmental sound and the second ear 030 side environmental sound can be simultaneously listened to by the second ear 030. In the second mode, the second sound pickup assembly 110-B picks up and converts the ambient sound on the second ear 030 side of the target user into the second ambient signal y ₂, and the second sound pickup assembly 120-B converts the second driving signal u ₂ corresponding to the second ambient signal y ₂ into the second sound and delivers the second sound to the first ear 040 openly, thereby enabling the first ear 040 to simultaneously listen to the ambient sound on the first ear 040 side and the ambient sound on the second ear 030 side. It follows that the acoustic device 200 shown in fig. 4 can be adapted to all monaural hearing impaired users, regardless of which ear the user is hearing impaired in particular. That is, the acoustic device 200 is applicable to users with severely impaired left ear hearing, and to users with severely impaired right ear hearing, and has wide applicability.

In some embodiments, to enable the acoustic device 100 of fig. 1 to be used by all types of monaural hearing impaired users as well, both the target pickup assembly 110 and the target sound emitting assembly 120 may be of a detachable design. In this way, the target user can set the target sound pickup assembly 110 and the target sound emitting assembly 120 in place according to the type of the one-ear hearing barrier itself (i.e., which ear is the weak ear). For example, if the first ear of the target user is a weak ear, the target sound pickup assembly 110 may be disposed in the first ear-hook assembly 320-a (e.g., may be disposed in a housing cavity formed by the first housing 321-a or in a housing cavity formed by the second housing 322-a), and the target sound pickup assembly 120 may be disposed in the second ear-hook assembly 320-B (e.g., may be disposed in a housing cavity formed by the first housing 321-B). If the second ear of the target user is a weak ear, the target sound pickup assembly 110 is disposed in the second ear-hook assembly 320-B (e.g., may be disposed in a receiving cavity formed by the first housing 321-B or in a receiving cavity formed by the second housing 322-B), and the target sound pickup assembly 120 is disposed in the first ear-hook assembly 320-a (e.g., may be disposed in a receiving cavity formed by the first housing 321-a).

It can be seen that by designing the target sound pickup assembly 110 and the target sound producing assembly 120 to be detachable, the acoustic device 100 can meet the hearing aid needs of different types of monaural hearing impaired users by deploying only one sound producing assembly and one sound pickup assembly.
