Embodiment Construction

[0024] The present invention will be described in detail below. However, the following detailed description and drawings do not limit the invention. Rather, the scope of the invention is defined by the appended claims.

[0025] The microphone device of the present invention has: a cylindrical grip portion; a microphone unit with a vibrating plate; a unit holder for holding the microphone unit; and a flexible member disposed on the back side of the unit holder so that the support unit holds and a protruding contact part protruding from the unit holder toward the back support part and contacting the back support part at the side of the protrusion.

[0026] According to this configuration, the protruding side surface of the protruding contact member comes into contact with the back support member to generate contact resistance. This contact resistance reduces sway and pitch of the microphone unit due to touch noise. Touch noise is thus reduced.

[0027] In addition, the micro...

Abstract

The invention provides a microphone device, comprising: cylinder holding part; microphone unit with the vibrating board; unit holding member for holding microphone unit. The back supporting board is installed on the back side of the unit holding member and is made up of flexible members in order to support unit holding member. The fins are extruding contacting member, which are extruded from the unit holding member to the back supporting board and contacts to the back supporting board at the extruding side. The shake and longitudinal inclination of the microphone unit producing touch complex tone is reduced by right of contact resistance.

Description

technical field [0001] The invention relates to a microphone device with reduced touch noise. Background technique [0002] Conventionally, hand-held microphone devices have been used for various purposes. In the microphone device, a microphone unit is provided in a cylindrical grip. In such a microphone device, it is important to reduce touch noise. The so-called touch noise is a noise generated by vibration when holding the grip part. As touch noise reduction structures, two types of structures, floating type and canceling type, are known. [0003] 8 and 9 show an example of a floating microphone device. The microphone device 101 has a grip portion 103 , a microphone unit 105 , and a unit holder 107 that holds the microphone unit 105 . The microphone unit 105 protrudes from the upper end of the grip portion and is covered with a net (not shown). The microphone unit 105 incorporates a vibration plate, and converts the vibration of the vibration plate corresponding to ...
