Description

Technical Field

[0002] With the continuous development of social economy and the continuous improvement of science and technology, more and more products are being manufactured and innovated. Microphone, scientifically known as microphone, is translated from the English word microphone (transmitter), also known as microphone, micro-phone. Microphone is an energy conversion device that converts sound signals into electrical signals. Microphones can be divided into dynamic microphones, condenser microphones, electret microphones and silicon micro-microphones, in addition to liquid microphones and laser microphones. The working principle of condenser microphones is to form a capacitor with two parallel metal planes as two poles. One electrode is made of an extremely thin vibrating film material, and the other electrode is made of a porous metal plate. The sound is transmitted through the air, causing the electrode made of the vibrating film material to move relative to the plate made of the porous metal plate. When the position moves, the capacitance between the diaphragm and the plate will change. The change in capacitance forms a weak current, which is transmitted to the loudspeaker, and then the fluctuating current is restored to sound in the opposite process.

[0003] The current sound collecting tube generally includes an inner tube and an outer tube. The inner tube is arranged inside the outer tube. A woven metal mesh and a damping material are arranged between the inner tube and the outer tube to achieve a shielding effect and a dustproof function. However, this sound collecting tube is relatively thick, occupies a large space, has a complex structure, is relatively heavy, is not easy to carry, and brings inconvenience to users. Therefore, it is necessary to study a new technical solution to improve the current sound collecting tube. Utility Model Content
