Problems solved by technology

[0003] However, in the above-mentioned conventional waterproof microphone, when a difference in air pressure occurs between the inside and outside of the above-mentioned waterproof cover, there is a problem that the above-mentioned waterproof cover is greatly deformed.
In this way, if the deformation of the waterproof cover increases, the range of sound transmitted to the microphone body by the vibration of the waterproof cover will change, and clear sound cannot be effectively transmitted.

Embodiment Construction

[0025] Hereinafter, the present invention will be described in detail based on the illustrated embodiments.

[0026] figure 1 A front view showing an embodiment of the waterproof microphone of the present invention. This waterproof microphone includes a substantially C-shaped neckband 1 and a microphone part 2 attached to one end 1 a of the neckband 1 . An electrical signal line 3 extends from the microphone unit 2 .

[0027] The neckband 1 is made of elastic material such as synthetic resin, for example, and is detachably attached around the head. The above-mentioned microphone part 2 is a so-called throat-type microphone, which directly touches near the throat of the head to pick up sound.

[0028] Such as Figure 2A and Figure 2B As shown, the above-mentioned microphone part 2 includes a cylindrical shell 11, a cylindrical inner shell 12 installed in the outer shell 11, and a capacitive microphone body installed in the inner shell 12 and converting sound waves into el...

Abstract

The present invention provides a waterproof microphone capable of effectively transmitting clear sound. The waterproof microphone includes an outer shell (11) having an opening (11a), an inner shell (12) mounted on the outer shell (11), and an inner shell (12) mounted on the inner shell (12c) in such a manner that it is exposed from one end surface (12c) of the inner shell (12). The microphone body (20) in the inner shell (12), the diaphragm (13) waterproofly installed on the opening (11a) of the outer shell (11), are arranged on one end surface of the inner shell (12) (12c) and the elastic member (16) that combines the above-mentioned inner shell (12) and the above-mentioned vibration plate (13). Therefore, even if a difference in air pressure occurs between the inside and outside of the housing (11), the elasticity of the elastic member (16) can suppress the deformation of the diaphragm (13).

Description

technical field [0001] The present invention relates to a waterproof loudspeaker (hereinafter referred to as a waterproof microphone) capable of collecting sound well over a wide frequency band even in places exposed to high humidity such as rain and fog, high mountains with low air pressure, and water with high air pressure , especially related to throat-type microphones in the manner. Background technique [0002] Conventionally, as a waterproof microphone, there is a waterproof microphone that covers the entire condenser microphone body that converts sound waves into electrical signals with a waterproof cover (see Patent Document 1: Patent No. 3486151). [0003] However, in the conventional waterproof microphone described above, when a difference in air pressure occurs between the inside and outside of the waterproof case, there is a problem that the waterproof case is greatly deformed. In this way, if the deformation of the waterproof cover increases, the range of sound...
