Example Embodiment

[0033] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0034] Embodiment 1 of the present invention is shown in Fig. 2, Fig. 3, Fig. 4, Fig. 8, a kind of skin-contact capacitive vibration pickup, comprises metal shell 1, backing ring 2, vibrating part 3, insulating washer 4, back pole plate 5. The back pole seat 6, the metal connecting ring 7 and the circuit board group 8, the metal shell 1 is a cylindrical box structure with an open end. The backing ring 2 is circular, the outer diameter of the backing ring 2 matches the inner diameter of the metal casing 1 , and the backing ring 2 is placed flat in the metal casing 1 and contacts the inner bottom surface of the metal casing 1 . The vibrating part 3 includes a circular thin metal plate 31 and a circular counterweight 32, the counterweight 32 is fixed on one side of the thin metal plate 31, the diameter of the thin metal plate 31 matches the inner ...

Abstract

This invention discloses a skin-touch capacitor vibration pick-up unit including a metal shell, mat rings, vibrating components, insulation gaskets, a back pole plate, a back-pole base, a conduction connection ring and a CB set, in which, its vibration component is a metal thin plate with a fixed balance at the back or a metal thin plate fixed by cantilever structure, when speaking, the vibration at the throat transfers to the vibration part to utilize the inertia vibration of which to alter the capacitance variance between vibration part and back-pole plate then to be converted to alternate signal voltage varied along with the vibration to be output by the CB set, since the thickness of the metal thin plate is about 1000 times of the vibration membrane, it will not vibrate when being influenced by sound waves and noises will not play any role to it, and this invented shell plays the role of sound insulation since it's no use to have sound holes.

Description

technical field [0001] The invention belongs to the technical field of communication electroacoustics, and in particular relates to a skin-touch capacitive vibration pickup. Background technique [0002] For the field of communication technology, how to carry out clear and effective communication in firefighting fields, military battlefields and various high-noise environments has always been an urgent problem to be solved. In this field of communication, the electro-acoustic transducing device mainly used at present is the contact vibration pickup, and its main transducing principle is electromagnetic and piezoelectric. There are some unsatisfactory problems in terms of performance. [0003] With the development of science and technology, the application of capacitive measurement principle is becoming more and more extensive. The capacitance between objects is closely related to its structural parameters. By changing the structural parameters and changing the capacitance ...
