The working principle of the receiver

2018-3-19 17:11:25 浏览:

Generally speaking, the receiver is a moving coil receiver, whose principle (physical principle) is similar to that of a traditional moving coil speaker: the changing audio signal is fed into the sound circle, the ring is placed in the magnetic gap of a permanent magnet circuit, and the electromagnetic field force (Lorentz force) is driven by the change of the current caused by the changing current. The vibration is driven up and down, and the vibrating membrane is driven to drive the front and rear air to generate sound waves.
Because what needs to be output is the electroacoustic characteristics of a pressure field, usually, the structure of the receiver will also be configured with the sound and sound damping of the front and back, which is used to adjust the audio characteristics.
Although there are many other types of receiver, but so far, the moving coil receiver has become the mainstream audio device for the audio terminal in mobile phone and fixed phone because of its high performance price ratio, mature production process, variable shape size and extraction mode.
The receiver converts the amplified electrical signals into sound signals. The audio signal processed and amplified is sent to the receiver and converted from the receiver to the sound signal, and then output to the external auditory canal through ear hook and sound tube. Hearing aids is a kind of micro - and tongue spring or loudspeaker. It is completely different from ordinary moving - coil loudspeaker structure. It is characterized by high sensitivity and small size, but the manufacturing process is complex and precise.
In addition, there is a special type of receiver, bone guide, which is suitable for the collapse of the ear canal or other conductive factors which can not use the ear mold. It is the conversion of electrical energy to mechanical vibration.
