Head-mounted omnidirectional high-fidelity electronic microphone device

Abstract

The invention discloses a head-mounted omnidirectional high-fidelity electronic microphone device. The device comprises a telescopic structure, The telescopic device comprises a first connecting rod and a second connecting rod. a clamping block is fixedly mounted on the inner surface of the first connecting rod; Clamping blocks are fixedly installed on the two sides of the second connecting rod. afirst connecting arm is fixedly mounted at one end of the first connecting rod; A microphone sleeve is fixedly installed at one end of the first connecting arm, a function box is fixedly installed atone end of the second connecting rod, a volume adjusting button is arranged on the outer surface of the function box, a signal receiving module is arranged in the function box, and an electricity storage module is arranged on one side of the signal receiving module. In conclusion, the head-mounted omnidirectional high-fidelity electronic microphone device has the beneficial effects that the head-mounted omnidirectional high-fidelity electronic microphone device adopts a telescopic structure and a folding structure, so that the length of the microphone can be conveniently changed, the microphone can be well folded for retraction, and the head-mounted omnidirectional high-fidelity electronic microphone device is simple in structure and convenient to use.

Description

technical field [0001] The invention relates to the field of microphones, in particular to a head-mounted omnidirectional high-fidelity electronic microphone device. Background technique [0002] Microphone, scientifically called microphone, is an energy conversion device that converts sound signals into electrical signals, also known as microphones and microphones. In the 20th century, the microphone developed from resistive conversion of sound and electricity to inductive and capacitive conversion, and a large number of new microphone technologies gradually developed, including aluminum ribbon, dynamic coil and other microphones, as well as the widely used condenser microphones and electret microphones. Body microphone, in order to sometimes work, a head-mounted omnidirectional high-fidelity electronic microphone is needed to meet people's needs. Now the head-mounted omnidirectional high-fidelity electronic microphone has some disadvantages. (1) It is not possible to chang...

In the 20th century, the microphone developed from resistance conversion to inductive and capacitive conversion, and a large number of new microphone technologies gradually developed, including aluminum ribbon, dynamic and other microphones, as well as the widely used condenser microphones and electret microphones. Body microphone, in order to sometimes work, a head-mounted omnidirectional high-fidelity electronic microphone is needed to meet people's needs. Now the head-mounted omnidirectional high-fidelity electronic microphone has some disadvantages. (1) It is not easy to change its length; (2) It cannot be effectively folded, and it is inconvenient when retracting. We design a head-mounted omnidirectional high-fidelity electronic microphone device
