A new type of microphone

Abstract

The invention relates to a new type of microphone, comprising a microphone, an upper cover and a base, a control panel is arranged on the upper cover, a telescopic mechanism is arranged between the microphone and the upper cover, and several A connection mechanism; the connection mechanism includes a slot arranged in the wall of the upper cover, a moving chamber connected to the slot, an electromagnet connected to the inner wall of the moving chamber and several guide rods, sleeved on the guide rod The spring on the spring, the limit rod connected to the spring, the metal rod connected to the limit rod, the limit block connected to one end of the metal rod and the connecting plug-in located at the upper end of the base, the inner wall of the connecting plug-in There are several limit slots, the limit blocks are located in the limit slots, the electromagnet is connected to the control panel, and the upper cover is provided with a rotating ball holder. The new microphone can easily adjust the height and tilt angle of the microphone, and the upper cover and the base can be easily installed and disassembled, which is convenient for maintenance.

Description

technical field [0001] The invention belongs to the field of microphones, and in particular relates to a novel microphone which is easy to install and disassemble. Background technique [0002] The microphone, also known as the microphone, is an electro-acoustic equipment, which belongs to the microphone and is a transducer for sound-to-electricity conversion. The sound wave acts on the electro-acoustic element to generate a voltage, and then converts it into electrical energy. Used in various sound amplification equipment. [0003] A microphone is usually classified by the way it transfers energy. Here we still divide microphones into dynamic microphones and condenser microphones according to the most common classification method for microphones in recording studios. [0004] A dynamic microphone is a microphone in which an electrical signal is generated by a conductor moving in a magnetic field. The coil is driven by the diaphragm to vibrate, so that the coil in the mag...

AI Technical Summary

Problems solved by technology

Features: Good frequency characteristics, flat amplitude-frequency characteristic curve in the audio range, which is better than dynamic microphones; non-directional; high sensitivity, low noise, soft; relatively large output signal level, small distortion, transient response performance Well, this is the advantage that the dynamic microphone cannot achieve; the working characteristics are not stable enough, the sensitivity of the low frequency band decreases with the increase of use time, the life is relatively short, and the DC power supply is required for operation, which makes it inconvenient to use

[0006] At present, the upper cover and the base of common microphones are mostly connected by screws and positioning rods. Generally, multiple sets of screws are required for positioning and connection. Changes, causing the microphone to occupy space on the table cannot be adjusted
