Description

Make things convenient for wearing formula microphone that teacher's lecture used

[ technical field ] A method for producing a semiconductor device

The utility model relates to a microphone technical field, concretely relates to make things convenient for wearable microphone that teacher's lecture used.

[ background of the invention ]

A microphone is an energy conversion device that converts a sound signal into an electrical signal. Microphones can be classified into two types, an electrodynamic microphone and a capacitance microphone, according to the transduction principle of the microphones.

Microphones have evolved from originally resistive to acoustic-electric to inductive, capacitive conversion, and a number of new microphone technologies have evolved, including microphones such as aluminum-driven coils, and capacitive and electret microphones, which are currently in widespread use.

The working principle of the coil microphone is that human voice vibrates a vibrating diaphragm through air, and then a magnetic force field is formed on an electromagnetic coil winding on the vibrating diaphragm and a magnet surrounding a moving coil wheat head for cutting to form weak fluctuating current. The current is fed to the loudspeaker and the fluctuating current is converted to sound in the reverse process. The diaphragm of the capacitor microphone is made of fluorinated ethylene propylene mostly, the humidity performance is good, the generated surface charge is large, and the influence of humidity is small.

For the microphone used by the teacher, the teacher often needs to write on a blackboard or perform one-to-one simple tutoring with the students in an interactive teaching link during class, so that both hands need to be liberated. Therefore, teachers often select a collar-clip microphone and a head-mounted microphone.

When the collar clamp type microphone is used, the following problems exist: the neck clip type microphone is arranged in front of the chest of a user in a clamping mode, and the distance between the neck clip type microphone and the mouth of the user is long, so that insufficient sound pressure exists, the use of the microphone is affected, and the better sound effect cannot be guaranteed.

When the head-mounted microphone is used, the following problems exist: the head-wearing microphone is worn on the ear of a user, the microphone extends to the mouth, the distance between the microphone and the mouth of the user is short, and the sound pressure can be satisfied. But after the wearing time is long, the experience feeling and the comfort are poor, and the long-time wearing and use are not facilitated.
