Specific embodiment

Before the description of the embodiment of the present application, first the term in the embodiment of the present application is illustrated.

Data-interface refers to when carrying out data transmission to the interface of data connecting line output data.Common data interface is USB interface, Micro-USB interface etc..Wherein, USB interface be universal serial bus (English: Universal Serial Bus, Abbreviation: USB) it is a kind of serial bus standard and a kind of input/output interface for connecting computer system and external equipment Technical specification, be widely used in the information communications product USB interface such as PC and mobile device include Type-A interface, Type-B interface and Type-C interface etc., difference are applicable in scene and different demands for different interface types.

Loudspeaker is also known as " loudspeaker ".It is a kind of common electro-acoustic transducer device.There are many type of loudspeaker, although they Working method is different, but is all finally by generate mechanical oscillation push around air, make air dielectric generate fluctuation to Realize the conversion of " electricity-power-sound ".

The occurring mode of loudspeaker is following several:

1) moving-coil type.Basic principle comes from Fleming's Left Hand Rule, and the conducting wire and the magnetic line of force for having electric current one are vertical Put magnet north and south interpolar into, conducting wire will by both the magnetic line of force and electric current interaction and move, depended on a piece of vibrating diaphragm On this root conducting wire, as curent change vibrating diaphragm just generates the movement of front and back.

2) electromagnetic type.It is moved in the intermediate erection of a U-shaped magnet and cuts iron plate (armature), when electric current flowing through coil Armature can be generated by magnetization and magnet inhales reprimand phenomenon, and drives vibrating diaphragm to move simultaneously.This design cost is cheap but ineffective, So being mostly used on mouthpiece and insert earphone.

3) inductance type.It is close with electromagnetic type principle, but armature doubles, and two voice coils on magnet and asymmetry, when Signal electric current by when two armatures in order not to magnetic flux can push mutually and move.It is that not exist together be that inductance is with electromagnetism Lower frequency can be regenerated, but efficiency is but very low.

4) electrostatic.Basic principle is coulomb (Coulomb) law, usually with the diaphragm of plastic colloid plus inductance such as aluminium Property material vacuum vaporization process, two diaphragms put face-to-face, when wherein it is a piece of add positive current high pressure when another will feel Low current should be gone out, push air that can make a sound by attraction repulsive interaction each other.Electrostatic monomer is due to light weight And vibration dispersion is small, so it is readily available as clear as crystal Hi-Mid, it is dynamic to bass to feel inadequate, and its efficiency is not Height, the former and easy gather dust using direct current.

5) plane formula.Voice coil designs are still that moving-coil type is the theme, but the plane that cone basin vibrating diaphragm is changed to honeycomb structure is shaken Film, because of few people's cavity effect, characteristic is preferable, but efficiency is also relatively low.

6) silk ribbon formula.Not traditional voice coil designs, vibrating diaphragm are made of with very thin metal, and electric current flows directly into body Make its vibratory sound.Since its vibrating diaphragm is exactly voice coil, so quality is very light, transient response is splendid, and high frequency response is also fine.

7) horn-type.Vibrating diaphragm push be located at horn bottom air and work because sound transmit when do not spread Efficiency is very high.

Electric connector is the element for connecting electric wiring.Electric connector is alternatively referred to as plug, is widely used in various electrical In route, play a part of connection or disconnecting circuit.
