Novel microphone

Abstract

The invention relates to a novel microphone, which comprises a microphone, an upper cover and a base, and is characterized in that the upper cover is provided with a control panel, a telescopic mechanism is arranged between the microphone and the upper cover, and a plurality of connecting mechanisms are arranged between the upper cover and the base; the connecting mechanism comprises a slot formedin the wall of the upper cover, a moving cavity connected with the slot, an electromagnet and a plurality of guide rods connected to the inner wall of the moving cavity, the springs arranged on the guide rods in a sleeving manner, limiting rods connected to the springs, metal rods connected to the limiting rods, the limiting blocks connected to one ends of the metal rods, and a connecting inserted piece arranged at the upper end of the base; a plurality of limiting grooves are formed in the inner wall of the connecting inserted piece, the limiting blocks are located in the limiting grooves, the electromagnet is connected with the control panel, and a rotating ball clamping base is arranged on the upper cover. According to the novel microphone, the height and the inclination angle of the microphone can be conveniently adjusted, the upper cover and the base can be conveniently assembled and disassembled, and maintenance is facilitated.

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
