Throat vibration type microphone and hand-free communication device comprising same

Abstract

A throat-vibration-type sensor (A) and a communication hands-free device (B). The interior of a box body (1) of the throat-vibration-type sensor (A) is only provided with a ceramic sheet (2) and a copper sheet (3), wherein the ceramic sheet (2) and the copper sheet (3) are electrically connected to an amplification circuit (4) for voice communications. It has the advantages that the volume and thickness are reduced, the costs are reduced, the assembly is easy, and the reception effect is increased. The throat-vibration-type sensor (A) can be combined with the communication hands-free device (B) which is provided with a control circuit board (5), a sound amplification device (6) and a battery unit (7), and the throat-vibration-type sensor (A) can be used for relieving the interference of external noise. Compared with a communication hands-free device of an air-type microphone, the communication hands-free device (B) combined with the throat-vibration-type sensor (A) can avoid being unable to identify a voice signal because of a wind shear sound caused by a high moving speed of a wearer, so as to improve the overall utilization efficiency of the communication hands-free device (B).

Description

technical field [0001] The invention discloses a throat-vibration microphone and a communication hands-free device including the microphone, especially through the simplification of the components of the throat-vibration microphone, so that when it is implemented alone or combined with a communication hands-free device, it can reduce the Low cost, easy assembly, and the function of improving the radio effect. Background technique [0002] The known throat vibrating microphone cannot be installed and used on the nose pad of glasses because of its large size, so the structural design must be changed and reduced to meet the requirements, and its structure and conductive materials for transmitting audio vibration signals Also can not satisfy the audio frequency vibration signal conduction demand of nasal bone skin. This kind of product structure has the patents of Taiwan Patent Announcement No. 444998 "Ceramic Piezoelectric Microphone", No. 462575 "Improved Structure of Throat ...

AI Technical Summary

Problems solved by technology

[0011] Based on the above, it can be seen that the technical problem to be solved by the present invention is that for the nasal bone conduction microphone and the throat vibration microphone in the prior art, the volume or thickness is still large, there are many parts, and the assembly is difficult and difficult due to the imperfect design. To provide an effective technical solution for the defects of radio reception and poor sound quality
