Abstract

The utility model discloses a bone-conduction microphone and receiver assembly, which comprises a casing, a bone-conduction mike with closed air chamber structure, a bone-conduction loudspeaker, lead-out wires and an output terminals. The utility model is characterized in that the surface of one side of the casing is provided with two holes, the receiving surface of the bone-conduction mike with closed air chamber structure and the vibration surface of the bone-conduction loudspeaker respectively extend out of the holes and are higher than the surface of the casing, the casings of the bone-conduction mike with closed air chamber structure and the bone-conduction loudspeaker respectively wrap one layer of soft pad at least, the outermost layer of soft pad is fixed at the inner side of the casing, and the lead-out wires and the output terminals of the bone-conduction mike with closed air chamber structure and the bone-conduction loudspeaker are fixed outside the casings. The bone-conduction microphone and receiver assembly of the utility model utilizes a human body skull to conduct vibration and spread sound. The utility model can eliminate the influence caused by ambient noise and can satisfy dialogue requirement in noisy environment. Due to the small size, the utility model is arranged in the devices of telephones, mobile phones, ear microphones, etc.

Description

Osteoacusis send, the receiver assembly

Technical field

The utility model relate to a kind ofly give, the receiver assembly, particularly with sending of forming of bone-conduction microphone and bone-conduction speaker, receiver assembly.

Background technology

The loud speaker of normal air conduction, the interference that microphone is subjected to environmental noise in use easily are so be not suitable for using in noisy environment by sending of forming of normal air conduction loud speaker and microphone, receiver.Bone-conduction microphone and loud speaker are to utilize the medium of people's bone as conduct vibrations, and the health that only needs its vibration plane to be adjacent to the user can import vocal cord vibration into microphone by bone, perhaps directly imports the vibration of loud speaker into ear bones by skull.The osteoacusis element directly utilizes the bone transmitting vibrations, has shielded the vibration of transmitting in the air, therefore utilizes the conversation of osteoacusis element can avoid the influence of environment sound.The osteoacusis device needs to be adjacent to user's face in use, and the Oscillation Amplitude of osteoacusis element is relatively large, thus bone-conduction speaker and bone-conduction microphone need when using jointly far away at interval, to reduce mutual interference effect.So existing bone-conduction microphone and bone-conduction speaker are formed send, the receiver assembly volume is bigger, is difficult for being installed in the equipment such as phone, mobile phone, headset.

Summary of the invention

The purpose of this utility model is: provide that the less osteoacusis of a kind of volume send, the receiver assembly, it can be installed in the equipment such as phone, mobile phone, headset.

The technical solution of the utility model is:

A kind of osteoacusis send, the receiver assembly, include housing, the bone-conduction microphone of sealed gas chamber structure, bone-conduction speaker, lead-out wire and lead-out terminal, it is characterized in that, 2 holes are arranged on housing one side surface, the radio reception face of the bone-conduction microphone of sealed gas chamber structure and the vibration plane of bone-conduction speaker stretch out the surface that is higher than housing respectively from the hole, the bone-conduction microphone of sealed gas chamber structure and the shell of bone-conduction speaker are surrounded by at least 1 layer of cushion respectively, outermost cushion is fixed on the housing inboard, and the lead-out wire lead-out terminal of the bone-conduction microphone of sealed gas chamber structure and bone-conduction speaker is outside housing.

Described osteoacusis send, the receiver assembly, it is characterized in that, lead-out terminal is contact or pinned.

Described osteoacusis send, the receiver assembly, it is characterized in that, the microphone of the bone-conduction microphone inside of sealed gas chamber structure is a kind of in magneto-electric microphone, Electret Condencer Microphone, electret formula microphone, the piezo crystal microphone.

Described osteoacusis send, the receiver assembly, it is characterized in that, is fixed with fixedly ear in hull outside.

The beneficial effects of the utility model are: described bone-conduction microphone and loud speaker are propagated sound by human body skull conduction vibration, got rid of the influence of environmental noise, can in noisy environment, satisfy the dialogue needs, and volume is less, can be installed in the equipment such as phone, mobile phone, headset.

Fig. 3 is the cutaway view of the bone-conduction microphone of sealed gas chamber structure of the present utility model.

Wherein, Reference numeral: 1 is housing, and 2 is the hole, and 3 is cushion, and 4 is the bone-conduction microphone of sealed gas chamber structure, 5 is bone-conduction speaker, and 6 is lead-out wire, and 7 is lead-out terminal, and 401 is shell, and 402 is sealed gas chamber, 403 is boss, and 404 are radio reception face, and 405 is cushion, and 406 is microphone.

Embodiment

Below in conjunction with drawings and Examples the utility model is further specified.

Figure 3 shows that a kind of embodiment of bone-conduction microphone of the sealed gas chamber structure that the utility model adopts, the shell 401 that includes a plastic material, shell 401 inside are equipped with magneto-electric microphone 406, microphone 406 radio reception faces and 404 in the radio reception face that is fixed on shell 401 tops form sealed gas chamber structure 402, radio reception face 404 outers are around " U " shape rubber mount 405 is arranged, be pressed on the shell 401 by securing member, radio reception face 404 upper fixed have a boss 403, and boss 403 end faces are higher than shell 401 surfaces.During use, boss 403 is attached on user's the cheek, user's pronunciation causes that vibration is transmitted to radio reception face 404 by skull, and 404 vibrations of radio reception face cause the gas generation resonance in sealed gas chamber 402 structures, thereby give microphone 406 with sound conduction, vibration signal is converted to the signal of telecommunication.The utility model also can replace with the magneto-electric microphone condenser type, piezo crystal, electret formula microphone etc. as required.
