Description

Phalangeal body conduction sounding driving equipment

Technical Field

The utility model belongs to the technical field of bone conduction audio, and particularly relates to finger bone conduction sounding driving equipment.

Background

Bone conduction sound devices have a different pathway into the auditory center of the human body than traditional diaphragm sound devices and can deliver mechanical oscillations of sound waves without the need to close the ear canal to form a cavity to excite the tympanic membrane. The sound generating device is closely attached to the periphery of the human ear and the adjacent area of the head, so that the sound wave is transmitted to mechanically oscillate to form hearing. Existing bone conduction sounding devices are classified into headphones including headbands and helmets, and wired, wireless and true wireless headphones worn around the periphery of the human ear, according to their morphological distinction.

First, existing bone conduction microphone devices must continue to fit so tightly in a wearing engagement that presses against the wearer's head, thereby causing discomfort to the user in the continued wearing. In addition, while it is possible to design finished products that produce less ineffective interference with the human ear through adequate ergonomic experimentation, it is difficult to design uniform size products that are commonly available to most wearers in a particular wear area because of the relatively narrow peripheral space of the human ear. This in turn brings with it the problem that the design dimensions of the bone conduction product are difficult to unify, so that the mass production cost is difficult to control.

Secondly, in order to avoid the wearing comfort problem caused by the tight fitting, the existing bone conduction earphone generally adopts a mixed conduction scheme for improving the output power of the sound generating device, and the mixed conduction scheme comprises the use of bone conduction and air conduction to output a mechanical oscillation signal of sound waves to the auditory system of a human body. While components of the sound emitting device that are not input into the human ear auditory system will spill out as mechanical oscillations of the sound waves with the housing of the audio device, forming unwanted signals of the mechanical oscillations. The sounding device and the host machine thereof comprise the useless signals generated by the non-sounding part shell which overflows and is emitted into the air to form leakage sound. When its sound pressure level has fallen below the hearing threshold of other surrounding non-wearers, the specificity of the receiver's operation for the wearer is destroyed, and the bone conduction sounding device essentially forms a loudspeaker effect, so that the privacy of hearing and communication is lost. The two problems are generally existed in the existing bone conduction microphone device and are difficult to be effectively and effectively solved due to the inherent characteristics that the existing technology sound-producing device is attached to the periphery of the human ear and the adjacent area, so that the application of the bone conduction technology and the finished product thereof as front-end output equipment of the audio sound-producing device in the fields of digital audio equipment and audio communication is influenced for a long time.

The embodiment provides a phalangeal body conduction sounding method, which comprises the following steps:

the finger bone conduction sounding driving device is contacted with the hand bone of the human body;

the human hand bone is used to press the periphery of human ear and excite the ossicle to oscillate, thus producing hearing.

Compared with the prior art, the finger bone conduction sounding method mainly has the application of good sound wave mechanical oscillation conduction performance on human hand bones, and the finger bone body and related soft tissues of the human body are replaced by one to one group of sounding devices which are originally positioned in a host and comprise bone conduction transducer elements excited by electric signals in the front sounding body or the stimulated sounding body in the existing bone conduction sounding device. The finger bone conduction sounding driving device generates sound wave mechanical oscillation and guides the sound wave mechanical oscillation into human hand bones, and the human hand bones transmit the sound wave mechanical oscillation to auditory ossicles through contact with the peripheries of human ears so as to generate hearing.

Referring to fig. 1-10, the present embodiment further provides a phalangeal body conduction sounding driving apparatus, including a source sounding body and a sound guiding front end, wherein the source sounding body converts an electrical signal into an acoustic mechanical oscillation; the sound guiding front end receives the sound wave mechanical oscillation through the non-gaseous conduction channel and is used for driving human hand bones to sound, the human hand bones are in contact with the sound guiding front end to form a first excited sound body, the human hand bones press the periphery of human ears, so that the sound wave mechanical oscillation is led in and excited to vibrate ossicles, and hearing is generated.

The drive device is disposed within a finger ring, finger cuff, hand ring, watch or glove. The human hand bone comprises metacarpal bones and phalanges, wherein the finger ring and the lantern ring are directly sleeved on the finger to be contacted with the phalanges, and the hand ring or the glove is sleeved on the wrist to be contacted with the metacarpal bones. The proximal phalanx, the middle phalanx and the distal phalanx all include their phalangeal bodies. Human hand bones in contact with the finger ring, finger cuff, hand ring, watch or glove receive the acoustic mechanical oscillations from the leading end of the sound guide and from the near to the far, conducting the acoustic mechanical oscillations to the phalangeal small heads of the distal phalanges. The finger with the phalangeal small head presses the outer periphery of the human ear and the adjacent temporal bones including the outer side of the tragus and the surrounding area of the outer auricular door, and the mechanical oscillation of sound waves is guided and excited into the auditory ossicles by the jawbone and the temporomandibular joint to enter the inner ear to excite hearing.

Referring further to fig. 1-2, based on the above-described phalangeal bone conduction sounding method, the applicant conducted the following test on sounding effect by using a spectrum analysis device.

The test principle is as follows:

the vertical axis is in dB, and is the relative value of the sound pressure level of the sound wave band spectrum. The relative value of the boost level formed for the change in airflow caused by the peripheral deformation of the device caused by the bone conduction transducer obtained by vibrating diaphragm microphone equivalent and the change in the size of the cavity formed between microphones changes.

The higher the value, the greater the bone conduction transduction oscillation amount acquired on the corresponding device equipment configuration of the corresponding frequency, and the magnitude of the bone conduction transduction oscillation amount is marked by using a logarithmic method, and the transverse axis of the spectrogram is the frequency, and the interval of the spectrogram is from zero hertz to 20 kilohertz.

The test uses a plurality of discrete test points as the sweep output of a reference oscillation source, and various types of oscillators including a source oscillator and a tested oscillator send mechanical oscillation signals sent by the oscillators or conducted by the oscillators to equivalent test equipment, so that the values of the oscillators only have reference values.

It is noted that the frequency response at frequencies of 50 hz and below is of no reference value, since the dc side of the spectrum analysis device cannot sufficiently overflow its dc component.

The spectrum line with the higher ordinate is the maximum oscillation quantity acquired at the corresponding frequency point in the spectrum analysis process, and the transduction capability of the type of oscillator when a single-frequency point audio oscillation signal with the corresponding equal voltage is converted into a mechanical oscillation signal and transmitted to test equipment.

The spectrum line with the lower ordinate is the condition when being collected in real time, and because the test equipment operates in real time, the spectrum line with the lower ordinate is not higher than the spectrum line with the higher ordinate in value, namely the peak value, and the peak value can be used as a reference of a surrounding environment noise substrate or abnormal sound in the test chart. Because the testing environment involves physical contact between the transducer and the testing device, the peak represented by the envelope of the spectrum with the lower ordinate represents abnormal sound of the contact, the plugging, the friction or the audio break generated in other testing processes, and the intensity of the abnormal sound can be used for effectively transmitting the mechanical oscillation energy actually generated by the corresponding bone conduction transducer.

Fig. 1 shows the frequency response of the voice driving device for finger bone conduction, which corresponds to the audio frequency section collected by the abdomen end of the index finger, especially the human voice section when the voice driving device is configured on the middle phalange of the index finger. From the test results, the human phalanges have good excitation capacity for acoustic mechanical oscillation.

With further reference to fig. 2, under the same test environment, fig. 2 is an equivalent pickup detection environment configured 1 cm away from the abdomen of the index finger, so that when the abdomen is far away from the receiving environment, the mechanical oscillation is significantly attenuated, the recorded frequency response mainly comes from the leakage sound of the source sounding body attached to the middle phalanx, and the mechanical oscillation extending towards the distal phalanx on the stimulated sounding body and the sound guide path thereof is not effectively collected by the pickup device. The leakage spectrum of the whole phalangeal body conduction sounding driving device is obviously disproportionate to the sound conduction spectrum generated by phalangeal body conduction and has different envelopes, so that the bone conduction sound transmission characteristics which are obviously different from those of the excited sounding body when the excited sounding body is loaded in the external device are reflected.

From the above test data, it can be seen that the bone tissue and its surrounding soft tissue have good sound guiding properties to surround the phalangeal body as the first excitation body, and the human skin of its surrounding soft tissue has significantly superior properties to those of the existing bone conduction sounding device housing, so that the sound wave signals carried and conducted by its internal main structure can be prevented from being emitted from its surface to leak into the air, and the problem of sound leakage can be sufficiently solved while a continuous bone conduction sound transmission link is constituted.

Meanwhile, the sounding device formed by sounding the phalangeal body contacts the peripheral auditory system of the human ear through the finger and abdomen of the corresponding finger or fingers, and comprises the outer side of the tragus, the rear upper wall and the front lower wall of the external auditory canal, and the adjacent temporal bones, the jaw bones and the human skin outside the temporomandibular joint to complete conduction and receiving of acoustic mechanical oscillation. The fitting of the autologous finger abdomen to the relevant area has significantly comfortable use and wear conditions compared to materials made of non-autologous sound emitting devices. Therefore, the probability of rejection reaction is remarkably reduced, and the problem of comfort level of the bone conduction sounding device in receiving the call can be fully solved.

In this embodiment, the source sounding body includes an audio transducer, an audio signal generating circuit, and a battery, and the audio signal generating circuit is electrically connected to the audio transducer and the battery, respectively. The audio signal generating circuit is used for receiving and processing the electric signals related to the audio information, the audio transducer is used for converting the electric signals into sound wave mechanical oscillation, and the battery is used for supplying power to the audio transducer and the audio signal generating circuit. In this embodiment, the source sounding body is preferably a piezoelectric ceramic or a piezoelectric motor.

In this embodiment, the sound guiding front end is provided with an extension portion contacting with the outer periphery of the human ear, and the extension portion is used for forming a second excitation body and directly guiding and exciting the acoustic wave mechanical oscillation into the ossicular oscillation, so as to generate hearing. The sound guiding front end transmits the sound wave mechanical oscillation generated by the source sound generating body to the extension part to excite auditory ossicles to generate hearing, so that hearing sound is formed, and a sound signal can be further enhanced.

When the phalangeal body conduction sounding driving device is placed in a bracelet, a watch or a glove, the extension part can be directly extended from the wrist position to be fixed on a phalangeal joint, can be directly contacted with the periphery of a human ear to be used as a second sounding body for sounding, can be directly contacted with phalangeal bodies in the phalangeal joint, and can directly transmit sound wave mechanical oscillation into the phalangeal bodies, so that the distance between the phalangeal bodies and the phalangeal body sound conduction driving device is reduced, the transmission of sound wave mechanical oscillation in the phalangeal bodies is enhanced, and leakage sound is further reduced.

Based on the basic principle and the structure of the finger bone conduction sounding driving device, the finished product manufacturing structure can comprise the following embodiments.

In particular, the first housing 12 and the second housing 13 are rotatably connected by a flexible material or rotational connection to accommodate movement between phalanges. The lantern ring 11 is fixed on the first shell 12 and/or the second shell 13 and sleeved on the finger joint, two lantern rings 11 can be sleeved on the first bulge and the second bulge respectively according to requirements, and the inner surface of the lantern ring 11, the inner surface of the first shell 12 and the inner surface of the second shell 13 serve as sound guiding front ends which are directly contacted with the finger bones, so that stable contact can be ensured when the finger moves.

One finger shank, finger small head and one or more areas adjacent thereto, which are brought into the proximal phalanx of the index finger by the first housing 12 through its inner surface and its associated collar 11, are closely fitted into the index finger, whereby mechanical oscillations occur and are further transferred into the middle and distal phalanges. The other passage is formed by the second housing 13 through its inner surface and its associated collar 11, which directs sound waves into the middle phalanx of the index finger, thereby causing mechanical oscillation of the excited sound body.
