Embodiment Construction

[0031] A recording device used in a noisy environment provided by this embodiment, such as figure 1 As shown, it includes a throat bone conduction microphone, a processor, an integrated chip, a memory, a loudspeaker, a key module and a power supply for supplying power to the above modules, and the processor, memory, loudspeaker and key module are all connected to the integrated chip.

[0032] Among them, the laryngeal bone conduction microphone is connected with the processor to collect the voice signal and convert the voice signal into an electrical signal for output. The laryngeal bone conduction microphone is used to replace the traditional microphone, mainly relying on the strength of the throat muscles when making a voice. The mechanical vibration forces the entire laryngeal microphone to vibrate accordingly, so that the polarized piezoelectric ceramic sheet in the microphone is subjected to mechanical vibration to generate strain, and an electromotive force corresponding ...

Abstract

The invention discloses a recording device applied to a noisy environment, and relates to the technical field of recording devices. The recording device comprises a throat bone-conduction transmitter,used for collecting a voice signal, and converting the voice signal into an electrical signal for outputting; a processor, connected with the throat bone-conduction transmitter and used for receivingthe electrical signal output by the throat bone-conduction transmitter, controlling the size of the electrical signal to be within a preset range, and converting the electrical signal into a digitalsignal for outputting; an integrated chip, connected with the processor and used for receiving the digital signal output by the processor and processing the digital signal into voice data; a storage,connected with the integrated chip and used for storing the voice data; a loudspeaker, connected with the integrated chip; and a key module, connected with the integrated chip and used for controllingthe work of the throat bone-conduction transmitter and controlling the loudspeaker to play the voice data and stop playing the voice data.

Description

technical field [0001] The invention relates to the technical field of recording devices, in particular to a recording device used in noisy environments. Background technique [0002] Voice information collectors have been widely used in news interviews, meeting records, market research, etc., and are rapidly entering our work and life. Among the many portable recording devices, there are cassette tape recorders, MD players, portable DAT recorders, interviewers, etc., which have their own characteristics, but they all have great defects in sound effects in complex environments. Contents of the invention [0003] The technical problem to be solved by the present invention is that the current voice information collector cannot collect voice information with better sound effects in a complex environment, overcome the shortcomings of the prior art, and provide a recording device for noisy environments. [0004] In order to solve the above technical problems, the present inven...
