Title: Microphone system erasing mechanical noise
Inventor: FUJIMURA AKIHIRO
IPC: H04R1/02
Filed: 1979-02-15
Abstract: PURPOSE:To realize erasion of the noise applied through the solid state material by securing the  connection between the both output of the microphone attached to the position where the external  sound is applied through the air conduction and the microphone enclosed by the sound barrier  and in such way that the phases of the both output may be opposite to each other. CONSTITUTION:Diaphragm 12 is attached at the position where the external sound is applied by  the air conduction and through the pierced hole of the container; while diaphragm 15 is enclosed  by the sound barrier to prevent the external sound from being applied by the air conduction. Now  in case no sound enters the microphone from outside and only the noise is applied from inside of  the microphone main body through the solid state material, the vibration caused by the noise sent  from the microphone main body is transmitted to electrode 10. In this case, the absolute value is  nearly identical for the capacity change caused by the vibration between electrode 10 and diaphragms 12/15 with the opposite direction of the increment/decrement to be offset each other.  Accordingly, no current flows to load resistance 19. While in case the sound enters the microphone from outside by the air conduction, the vibration is transmitted only to diaphragm 12.  Thus the voltage occurs across resistance 19. Also in this case, the noise from the micropnone itself is offset and thus never enters sound recording circuit 12.

Abstract: PROBLEM TO BE SOLVED: To improve the error correction capability of a viterbi detector by adding a function detecting a disappearance error bit judged that the probability that a decoding error occurs in the viterbi detector is high, detecting the decoding error estimated with a maximum likelihood series and correcting the error. SOLUTION: The veterbi detector 24 outputs a veterbi decoded result and a disappearance error detection flag to a recording decoder 25, and the recording decoder 25 performs record decoding processing to process in byte here. When the disappearance error bit detection flag is 1, the matter that an error exists in the decoded byte is found, and the recording decoder 25 outputs a disappearance error byte detection flag as flg-ebyte=1 to an error correction decoder 26 together with a record decoding result. When the detection flag is 0, the matter that no error exists in the decoded byte is judged, and the decoder 25 outputs the detection flag as flg-ebyte=0 to the error correction decoder 26. The error correction decoder 26 inputs the detection flag to perform error correction.  Thus, when a disappearance error is detected precisely, double correction power of random error correction is obtained.
