Abstract

PURPOSE:To collect sounds with high S/N at a desired focal point position, by attaching plural microphone units to a printed base board in an arc-shaped array and so that the vibrating film surface is set vertical to the surface of the printed base board. CONSTITUTION:Attachment pin holes 2 are formed on the center line of the circumference of an arc-shaped printed base board 1. In this case, three holes 2 are set in a pair and five such pairs are arranged in an arc-shaped array. The folded coupling pins 3 are provided to the boad 1, and a microphone unit 5 is attached at the other side edge of the pin 3 respectively. The pin 3 is made of a conductive metal and set vertically to the hole 2. A pair of vertical pins 3 are molded with molding resin 4 so that they are put in parallel to each other. This resin 4 keeps a pair of pins 3 parallel to each other and at the same time secures the mechanical strength to hold the unit 5. Furthermore the resin 4 functions to suppress the vibrations transmitted from the board 1. Thus the vibrations which are changed into noises to the unit 5 can be suppressed.

Conventional configurations and their problems Conventionally, a method of sharpening the directivity of a microphone has been used as a means to pick up a target sound from a far away location with a good S/N ratio. However, if there is a noise source between the target sound and the microphone, there is a problem that it becomes difficult to pick up the sound (1'1) [S/N]. Therefore, the target sound is located one bundle νjl11 from the microphone,
Even if there is a noise source between the target sound and the microphone, the target sound can be picked up by S/N. j2. Attempts have been made to collect only the sound at a certain focal point. However, if multiple microphone units are simply arranged in an arc on a printed circuit board, the reflected sound from the printed circuit board will be directed to the microphone unit. There was a problem in that it became difficult to collect sound at the desired focal position with a good S/N ratio.

- The ficrophon unit has a main body 9 having a sound hole 6.
1~, a vibrating membrane 7 faces the sound hole 6, and a fixed electrode 8 faces the vibrating membrane 7, so that the vibrating membrane surface and the fixed electrode surface are perpendicular to the surface of the printed circuit board 1. Supported. The mold resin 4 has the function of making the pair of pins 3 parallel, the function of maintaining mechanical strength to support the microphone unit 5, and the function of suppressing vibrations transmitted from the printed circuit board 1, thereby increasing the mechanical strength. To suppress vibrations that cause noise to a microphone unit 5 while maintaining the same level of noise. Therefore, the material of the mold resin is not limited to plastic, but may also be made of highly hard rubber. on the other hand,
The connection pin 3 is an output line that leads the outputs of the microphone units 71 and 6 to the printed circuit board 1, and has the function of supporting the microphone unit 6 and the function of suppressing the photographing transmitted from the printed circuit board 1 to the microphone unit 5. This anti-vibration effect is achieved by the fact that a plurality of pins act as springs, and these pins are bent so that they are horizontal to the printed circuit board surface, so that the vibration membrane surface 7 of the microphone unit is perpendicular to the printed circuit board surface. Because it is taken over by
Even if the printer I/substrate vibrates as shown by arrow A in the figure, it rarely vibrates as shown by arrow B since the vibrating membrane surfaces are perpendicular to each other. Therefore, the microphone unit 6 does not output vibration noise components. The microphone unit 6 supported by the connection pin 3 is attached to the mounting IRF hinge hole 2 of the printed circuit board 1, and then the microphone unit 6 is assembled.
6 are arranged on the circumference, the above microphone unit 5
is attached so as to protrude from the inner circumferential end surface 1a of the printed circuit board 1. Therefore, the sound reflected from the printed circuit board 1 is not affected by the microphone unit 6, and the target sound at the focal position can be collected from outside.
