Problems solved by technology

[0005] However, as described in the above-mentioned patent document 1, in order to connect the microphone amplifier and the like to the conventional surface-type radio microphone through a cable, the microphone itself is not conspicuous, but the wiring of the cable is messy or visually detracts from the view.
[0006] Also, especially where there is a lot of traffic on stage, sometimes the cables get tripped up
As its previous issue, there was the hassle of having to route the cables every time the mic was set up

Embodiment Construction

[0026] Next, embodiments of the present invention will be described with reference to the drawings, but the present invention is not limited thereto. figure 1 , figure 2 It is an external perspective view of the face radio microphone of the present invention observed from different directions in front, image 3 It is a three-dimensional view of the internal structure with the radio cover removed, Figure 4 yes image 3 right side view of .

[0027] Such as figure 1 , figure 2 As shown, the face-radio microphone 1 has a flat microphone housing 10 as a whole, and the microphone housing 10 includes a base 20 and a sound collecting cover 23 covering the upper surface of the base 20 .

[0028] From the standpoint of improving the shielding performance against external electromagnetic waves, the base 20 is preferably made of a metal material such as zinc die-casting, and its bottom surface is formed flat so that it can be stably placed on a table or a floor. Such as image ...

Abstract

An object of the present invention is to provide an on-surface sound pickup microphone that is made wireless by eliminating the need for a cable for connection to a receiver. An on-surface sound pickup microphone 1 includes a flat microphone case 10 including a base portion 20 that has a flat bottom surface and a porous sound pickup cover 23 that covers a top surface of the base portion 20. The microphone case contains a microphone unit and a sound signal output circuit for the microphone. In the on-surface sound pickup microphone 1 has a battery housing portion 220 in which a battery as a power source is housed, and a light emitting portion 230 serving as transmission means for the sound signal output circuit to radiate infrared rays emitted by the infrared light emitting element, to the outside of the microphone; the light emitting portion 230 consists of, for example, a diffusion lens.

Description

technical field [0001] The present invention relates to a surface-collecting microphone used on a flat surface such as a table or a floor, and more specifically, to a wireless surface-collecting microphone that does not have a connection cable to a receiver. Background technique [0002] In the case of collecting sound in a conference room or on a stage, for example, a microphone with a long neck used standing on a table or the floor, such as a gooseneck microphone, may not be able to clearly utilize the sound coming from the table or the floor. The situation where the reflected sound is collected. In addition, the presence of the microphone may obstruct the eyes in a studio where TV broadcasts are performed or on a desk at a lecture venue. [0003] The microphone developed by applying the principle of reducing the influence of the reflected sound by making the microphone unit close to the reflecting surface is a surface-collecting microphone. As a conventional example ther...
