Description of the invention: [Technical field of invention] This invention shows a moon-shaped vibrating microphone that can isolate most of the scene noise and the right side of the glasses containing the microphone. The vibration that can be generated; the vibration that can be generated' allows the receiver to hear the bones of the speaker, the low background sound of the signal, the vibration of the microphone, the field/previous technique, a ru φ, the current (four), the health (four) Wind, its large size can not be installed in the nose pad position of the glasses, but must be measured 2 conductive materials can not meet the audio vibration signal transmission of the nose bone skin = second] such as China Patent Announcement No. 444998 "ceramic piezoelectric type The patent for the death of the microphone, which discloses a ceramic microphone with a lower cover and an upper cover. The two covers combine to create an accommodating space inside, and the accommodating coffee room is introduced by the lower cover-extension portion-signal line After passing through one of the substrates, a circuit board is connected to the other side of the circuit board with a ceramic piezoelectric piece, and a high-density foam is interposed between the ceramic piezoelectric piece and the inner surface fixing portion of the upper cover. The sound waves generated by the contact between the cover surface and the throat skin are transferred to the ceramic sheet by the foam and directly transferred to the signal output, so that most of the background noise is attenuated except for the user's voice. , using a high-density foam to do & transmission ^ medium, experimented with ampoules applied to the nasal bone skin, the resulting sound is poor and the volume is insufficient, and the high-density foam contacts the pressure The area of the film 1 201006265 • is also insufficient, resulting in a lower volume. In addition, as disclosed in the Patent Proclamation No. 75 of the “Protected Structure of the Laryngeal Vibrating Microphone”, it reveals a kind of throat vibration. The improved structure of the microphone, according to the structural features, comprises: a bottom cover having a circular groove, which can be coupled with a circular groove upper cover, so that the bottom cover and the upper cover are combined to form a body - the second of which is combined The circular groove forms a storage space; the circuit board is strongly attached with a piece of metal piezoelectric piece, further connecting the body; a double-sided adhesive body, the surface of which is attached to the inner circle of the upper cover _ _ The bottom of the groove shot '(four) - surface contact stickers On the surface of the board; the foamed cotton body's surface is covered in the circular groove of the bottom cover and tightly adhered to the bottom groove wall' while the other surface is tightly attached to the lower surface of the piezoelectric piece By means of the double-sided adhesive foam, the mud can be surely eliminated, and the mud which reduces and absorbs the vibration of the noise wave, and the large area of the bottom of the bottom of the foamed cotton body and the bottom cover can reach the sound wave surface of the speaker. Conduction is more extensive and true. However, the use of - foamed cotton as a medium for sound transmission, the use of money in the nose and the bones of the experiment and the experiment's sound quality is still poor and the volume is still insufficient, the recruitment of the body and the bottom of the bottom of the puzzle The coverage of the area, the axis makes the sound wave surface of the speaker more widely, when the microphone is not completely fit with the user: At the same time, the background noise is covered by the large area of the foamed cotton body, so that a large number The background sound is transmitted into the ceramic film. Moreover, as in the patent pending case of the "modified structure of the laryngeal vibrating microphone" of the Chinese Patent Publication No. 549780, the improved structure of the laryngeal vibrating microphone is disclosed, which comprises: a circular groove inside The bottom cover, the T-joining-with the upper cover of the trough, the bottom cover and the upper cover are combined to form a 201006265 foam body, one surface of which is covered in the circular groove of the bottom cover, the lower jaw® · the second wall On the other hand, the 'surface plate tightly attached to the metal piezoelectric piece is strongly attached to the upper surface of the metal piezoelectric piece; the surface of the special plate is attached to the surface of the rubber plate or the plastic material = the outer periphery of the soft separator It is closely connected to the upper cover of the two groove walls to form at least one of the closed cavity parts 2 (four) in the circular groove to enhance the utterance of the high passer. However, the foamed cotton body was used as an experiment not applied to the nasal bone skin, and the amount of blister, sputum, and sputum was still insufficient, and the patent was made of a flexible separator composed of a circuit board or a material. In addition to the shortcomings of the combination of the thickness of the wind and the thickness of the wind, the rubber material or the plastic material will also receive the external sound by the #面 or the contact point with the bottom cover, and will be transferred from the circuit board to the metal pressure. The film forms the source of the background noise. The basic principles of the vibrating microphones are the same. • The use of the material to transmit mechanical vibration waves is called “knocking the piezoelectric piece, = signal, but the structure is different. At the same time, the above vibration microphone, 疋 is suitable for detecting the throat sound of money vibration, so the packaging is large. Moreover, ^ the amplitude of the throat sound is very large, the signal noise is not high, and it can present a good throat sound. However, when this application is applied to the nasal bone, the nose is smaller than the QUI. The above-mentioned vibrating electric microphone is too large and exhibits a certain degree of noise, so that the correct nasal sound cannot be presented. However, the definition of the nasal sound and the recognition of the individual sound quality are better than the throat sound. Therefore, the present invention 201006265 uses the better sound transmission f to transmit the (four) special sound, the fresh structure skill and the structure (10), so that the ceramic: money film can be _ Presenting the original sound that is spoken through the nasal bones. In order to solve the above problems, it is desirable to provide a low background sound skin vibration microphone and to incorporate the microphone in combination with the glasses to overcome the disadvantages of the prior art. SUMMARY OF THE INVENTION It can be seen from the above that the main purpose of the low background sound skin vibrating microphone of the present invention must be applicable to the position of the nose pad of the glasses, so the thickness and size must be controlled within a relatively small range, and Ergonomic design, otherwise it will be quite asymmetrical and awkward when installed on the nose pads of the glasses; = externally, it should also be considered when the area of contact between the vibrating microphone and the nasal bone becomes small, and the nasal bone can still be clearly sensed.
