It will be appreciated that the data so used may be interchanged under appropriate circumstances such that embodiments of the application may be practiced in sequences other than those illustrated or described herein, and that the terms "first," "second," and the like are generally used herein in a generic sense and do not limit the number of terms, e.g., the first term can be one or more than one. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/", and generally means that the former and latter related objects are in an "or" relationship.

The technical solutions disclosed in the embodiments of the present application are described in detail below with reference to the accompanying drawings.

Referring to fig. 1 to 4, an embodiment of the present application discloses an earphone, which includes a housing 100, a sound pickup device 300, a sound generation device, an ultrasonic sensing module 200, and a battery module.

The casing 100 is a basic component of the earphone, and provides a mounting base for other components of the earphone, and certainly, the casing can also play a certain role in protection; specifically, the housing 100 is provided with an inner cavity 110, and the sound pickup device 300, the sound generation device, the ultrasonic sensing module 200 and the battery module are disposed in the inner cavity 110, but of course, each component needs to be disposed at a preset station in the inner cavity 110 to optimize the structural layout inside the earphone.

The sound pickup device 300 and the sound production device are functional components of the earphone, and the earphone can realize a sound production function based on the sound production device, so that a user can receive sound from the earphone; based on pickup device 300, the earphone can be ambient sound all around, so the user just can directly realize voice conversation through the earphone, also can realize intelligent interaction with the earphone.

In a conventional earphone, openings of the casing 100 are usually many, such as a signal transceiving opening, a microphone opening, and the like, and a sound guide channel needs to be respectively disposed to communicate these components and the openings, so that not only the structure inside the earphone is complex, but also the appearance consistency of the earphone is deteriorated.

In order to solve the above problem, the casing 100 of the present embodiment further has a first sound guide hole 120 and a first sound guide channel 410, and the inner cavity 110 is communicated with the first sound guide hole 120 through the first sound guide channel 410, so that various signals (such as sound waves, ultrasonic waves, etc.) outside the earphone can be transmitted to the inner cavity 110 sequentially through the first sound guide hole 120 and the first sound guide channel 410, and the signals in the inner cavity 110 can be transmitted to the outside of the earphone sequentially through the first sound guide channel 410 and the first sound guide hole 120.

Meanwhile, in this embodiment, the sound pickup device 300 and the ultrasonic sensing module 200 are located at a side of the inner cavity 110 close to the first sound guiding channel 410, at this time, the sound pickup device 300 can obtain a sound signal (such as a sound control instruction of a user) outside the earphone through the first sound guiding channel 410 and the first sound guiding hole 120, the ultrasonic sensing module 200 can receive or send an ultrasonic signal through the first sound guiding channel 410 and the first sound guiding hole 120, and calculate a distance between a limb (usually a hand, and in this embodiment, the hand is taken as an example) of the user and the earphone in real time, and the processor determines whether the hand of the user is close to or far away from the earphone through the distance, so as to adjust the volume of the earphone. Under this condition, sound pickup device 300 and ultrasonic sensing module 200 just commonly used same group to lead the sound hole and lead the sound passageway, both reduced the trompil quantity on casing 100, also reduced the sound passageway quantity of leading in the inner chamber 110, so can optimize the outward appearance performance of earphone certainly.

Certainly, the embodiment does not limit the specific gesture instruction for volume adjustment, for example, when the distance between the hand of the user and the headset increases, the volume of the headset may be set to be increased, and correspondingly, when the distance between the hand of the user and the headset decreases, the volume of the headset is set to be decreased; alternatively, when the distance between the user's hand and the headset decreases, the volume of the headset may be set to be increased, and accordingly, the volume of the headset may be decreased when the distance between the user's hand and the headset increases.

The conventional earphone generally implements volume adjustment through a capacitive touch mode, but when a user performs touch adjustment with a hand, the earphone may become loose and unstable to wear under the action of a finger, and sweat and the like on the finger may adhere to the surface of the earphone, which may easily cause sensitivity reduction of touch control. The earphone of this embodiment passes through the ultrasonic ranging principle, has realized the volume control to the earphone under the condition that user's hand does not touch the earphone, can enough make things convenient for the user to adjust the earphone volume, can not lead to the earphone not hard up because of adjusting the volume again simultaneously, has improved user experience effectively conscientiously.

Since the functional components need to supply power when in use, the battery module of the present embodiment is electrically connected to the ultrasonic sensor module 200, the sound pickup device 300, and the sound generation device, respectively.

In order to prevent external impurities (such as dust, water stain, etc.) from entering the inside of the earphone through the first sound guiding hole 120, the dust-proof net 500 may be correspondingly disposed at the first sound guiding hole 120 of the casing 100, and the dust-proof net 500 may block the impurities from entering the inner cavity 110.

Further, a movable baffle plate can be further disposed at the first sound guide hole 120, and the baffle plate has a first state and a second state, wherein in the first state, the baffle plate avoids the first sound guide hole 120, at this time, the earphone can be normally used, and meanwhile, the ultrasonic sensing module 200 can perform ultrasonic cleaning on the dust screen 500 by adjusting power; in the second state, the baffle is closed and covers the first sound guide hole 120, and the ultrasonic sensor module 200 can perform ultrasonic cleaning on the inside of the first sound guide channel 410 and the sound pickup device 300.

As can be seen from the above description, in the earphone disclosed in the embodiment of the present application, the inner cavity 110 is communicated with the first sound guiding hole 120 through the first sound guiding channel 410, and the sound pickup device 300 and the ultrasonic sensing module 200 are located at one side of the inner cavity 110 close to the first sound guiding channel 410, so that the sound pickup device 300 and the ultrasonic sensing module 200 can multiplex the same first sound guiding hole 120, the number of the holes formed in the wireless earphone is reduced undoubtedly, and the appearance consistency and the aesthetic property of the wireless earphone can be further improved.

Generally, the earphone of the present embodiment further has a control module, which makes a corresponding volume adjustment for the earphone after receiving the ultrasonic signal. Specifically, the control module is disposed in the inner cavity 110, the control module is electrically connected to the battery module, the ultrasonic sensing module 200 and the sounding device, and the battery module supplies power to the control module; based on the time difference of the ultrasonic sensing module 200 for receiving and sending the ultrasonic signal, the ultrasonic sensing module 200 is configured to detect a first distance between the limb of the user and the earphone, the larger the time difference is, the larger the first distance is, and the smaller the time difference is, the smaller the first distance is, so that the earphone can determine whether the limb of the user is close to or far away from the earphone through the ultrasonic sensing module 200; the control module is used for adjusting the volume of the sounding device according to the change value of the first distance, namely when the first distance is continuously changed, the control module can control the sounding device and adjust the volume.

The earphone of this embodiment further includes a speaker, the housing 100 further has a second sound guiding hole and a second sound guiding channel, the second sound guiding hole is communicated with the inner cavity 110 through the second sound guiding channel, and the speaker is disposed in the inner cavity 110 near one side of the second sound guiding channel. Specifically, the speaker functions as an electroacoustic transducer device, which can play a role in optimizing sound quality; after the sound waves generated by the loudspeaker are transmitted to the outside of the earphone through the second sound guide channel and the second sound guide hole in sequence, the sound waves can be received by the ear of the user.

In order to optimize the structural layout of the earphone, the first sound guiding hole 120 and the second sound guiding hole of the embodiment are distributed in opposite directions, so that the sound wave signal emitted by the earphone can be prevented from being interfered, and the overall sound quality effect of the earphone is improved.

In order to avoid the mutual interference between the acoustic wave signal and the ultrasonic wave signal in the first sound guiding channel 410, the first sound guiding channel 410 of the present embodiment may include a first sub-channel 411 and a second sub-channel 412, where the first sub-channel 411 and the second sub-channel 412 both communicate the inner cavity 110 and the first sound guiding hole 120, the sound pickup device 300 is located at a side of the inner cavity 110 close to the first sub-channel 411, and the ultrasonic sensing module 200 is located at a side of the inner cavity 110 close to the second sub-channel 412. With such a configuration, the sound pickup device 300 is opposite to the first sub-channel 411, and a sound wave signal outside the earphone can be received by the sound pickup device 300 through the first sound guide hole 120 and the first sub-channel 411 in sequence; the ultrasonic sensing module 200 is opposite to the second sub-channel 412, and can send out an ultrasonic signal and propagate to the outside of the earphone through the second sub-channel 412 and the first sound guide hole 120 in sequence, or the ultrasonic signal outside the earphone is received by the ultrasonic sensing module 200 through the first sound guide hole 120 and the second sub-channel 412 in sequence; as mentioned above, the arrangement mode can avoid the sound wave signal and the ultrasonic wave signal from completely propagating in the same sound guide channel, and can improve the mutual influence of the sound wave signal and the ultrasonic wave signal to a certain extent.

In the present embodiment, the specific configuration of the ultrasonic sensing module 200 is not limited. In the first embodiment of the earphone, as shown in fig. 3, the ultrasonic sensing module 200 of this embodiment may be of a transceiver structure, that is, the whole of the module has functions of sending and receiving ultrasonic waves, and when the module is used specifically, the sending and receiving operations of the ultrasonic sensing module 200 need to be executed at intervals, and ultrasonic distance measurement is realized in a circulating and reciprocating manner, so as to detect the limb movement of the user.

In the second embodiment of the earphone, as shown in fig. 4, the ultrasonic transducer module 200 of the present embodiment includes a transmitter 210 and a receiver 220, in other words, the ultrasonic transducer module 200 is a transceiver in a split configuration. Meanwhile, the second sub-passage 412 includes a transmitting branch passage 412a and a receiving branch passage 412b, both of the transmitting branch passage 412a and the receiving branch passage 412b communicate the internal chamber 110 with the first sound guide hole 120, the transmitting element 210 is located at a side of the internal chamber 110 close to the transmitting branch passage 412a, and the receiving element 220 is located at a side of the internal chamber 110 close to the receiving branch passage 412 b. In this case, the ultrasonic signal emitted from the transmitting element can be propagated to the outside of the earphone through the transmitting branch channel 412a and the first sound guide hole 120 in this order, and the ultrasonic signal outside the earphone can be propagated to the receiving element through the first sound guide hole 120 and the receiving branch channel 412b in this order.

It should be understood that, in the embodiment that the ultrasonic sensing module 200 is a separate receiving and transmitting configuration, since the transmitting element and the receiving element are separately disposed, the two elements can work simultaneously, so that the transmitting and receiving operations of the ultrasonic sensing module 200 are no longer performed at intervals, and the ultrasonic ranging can be continuously performed, so that the limb movement of the user can be detected more accurately, and the response speed of the earphone can be increased.

In order to make the sound pickup device 300 and the ultrasonic sensing module 200 share the same sound guide hole, one end of the first sub-passage 411 of the present embodiment communicates with the internal cavity 110, and the other end of the first sub-passage 411 may be bent to extend to communicate with one of the transmitting branch passage 412a and the receiving branch passage 412 b. It should be understood that the other end of the first sub-channel 411 may be in communication with either the transmission branch channel 412a or the reception branch channel 412b, and the embodiment is not limited thereto. Taking the other end of the first sub-passage 411 communicating with the transmission branch passage 412a as an example, since the transmission branch passage 412a communicates with the first sound guiding hole 120, the first sub-passage 411 also communicates with the first sound guiding hole 120 without any problem.

It should be noted that the first sub-channel 411 is bent, so that the second sub-channel 412 can be conveniently integrated into a regular channel, and the ultrasonic signal is prevented from being lost by an irregular channel; since the frequency of the ultrasonic wave signal is much higher than that of the sound wave signal, and the lower frequency signal is less affected by the irregularity of the propagation channel, the first sub-channel 411 arranged in a bent manner has less influence on the sound wave signal therein, and the normal sound receiving effect of the earphone is not affected.

Further, the apertures of the transmitting branch passage 412a and the receiving branch passage 412b of the present embodiment may be gradually reduced along the direction from the first sound guide hole 120 to the inner cavity 110. With this arrangement, when the transmitting element 210 transmits an ultrasonic signal, the ultrasonic signal can be radiated to a larger propagation area after entering the transmitting branch channel 412 a; during the process of the ultrasonic signal being propagated to the receiving element 220 through the receiving branch channel 412b, the ultrasonic signal is guided by the receiving branch channel 412b so as to be completely received by the receiving element 220.

In this embodiment, the earphone may further include a circuit board and a mold 400, the mold 400 presses the sound pickup device 300 and the ultrasonic sensor module 200 onto the circuit board, and a first sound guiding channel 410 is configured in the mold 400. Specifically, the circuit board serves as a mounting base for the sound pickup device 300 and the ultrasonic sensor module 200, and supplies power to them, and in this case, the circuit board is a part of the aforementioned battery module. The mold sealing portion 400 presses the sound pickup device 300 and the ultrasonic sensing module 200 on the circuit board, and thus, the sound pickup device 300 and the ultrasonic sensing module 200 are fixed and also have a certain protection and isolation effect.

Usually, the mold sealing part 400 may be a silicone material, but the embodiment is not limited to the specific material of the mold sealing part 400, and it may be made of other materials such as ceramic.

Based on the earphone disclosed in the foregoing embodiment of the present application, the embodiment of the present application further discloses a first earphone volume adjusting method, the earphone includes a housing 100, a sound pickup device 300, a sound generation device, an ultrasonic sensing module 200 and a battery module, the housing 100 is provided with an inner cavity 110, a first sound guide hole 120 and a first sound guide channel 410, the inner cavity 110 is communicated with the first sound guide hole 120 through the first sound guide channel 410, the sound pickup device 300, the sound generation device, the ultrasonic sensing module 200 and the battery module are disposed in the inner cavity 110, the sound pickup device 300 and the ultrasonic sensing module 200 are located on one side of the inner cavity 110 close to the first sound guide channel 410, the battery module is respectively electrically connected with the ultrasonic sensing module 200, the sound pickup device 300 and the sound generation device, and the earphone is in data connection with an electronic device.

wherein the first distance is a distance between the user's limb and the headset.

It should be understood that the first earphone volume adjustment method works based on the earphone interacting directly with the user's limb movements. Specifically, the function of adjusting the volume of the earphone can be awakened only when the change value of the first distance is limited within a first preset time period, which requires that the body movement needs to reach a certain frequency to adjust the volume of the earphone, so that the body of a user can be prevented from being adjusted by mistake when swinging normally near the earphone. In order to further avoid the misadjustment of the volume of the earphone, the sensing range of the limbs of the user can be preset through the ultrasonic sensing module, for example, the sensing range is preset to be within a range of 5-20 cm near the earphone so as to respond to the limb movement; furthermore, it may be preset that the limb of the user needs to stay within the sensing range for a second preset time period to wake up the function of adjusting the volume of the earphone, for example, the second preset time period may be set to 2s, 3s, and the like. Of course, the specific value of the first preset time period is not limited in this embodiment, and may be 0.5s, 1s, and the like.

The change value of the first distance is the moving distance of the limb of the user in the sensing range, which may be generally 1cm, and accordingly, the volume of the earphone may be adjusted up or down by 1 st gear; of course, the present embodiment does not limit the specific numerical value of the variation value of the first distance, and it may be 1.5cm, 2.0cm, or the like.
