Embodiment 1
As shown in Figure 4,5, the embodiment of the invention provides a kind of Double-sided receiver structure 300, the earphone structure 300 is wrapped
It includes: annular framework 310, magnetic core 340, annular permanent magnet 320, voice coil 330 and two vibrating diaphragms 360；The annular permanent magnet 320
It is mounted in the annular framework 310, the magnetic core 340 is arranged in the annular permanent magnet 320, and the voice coil 330 is arranged
On the magnetic core 340, the vibrating diaphragm 360 is separately positioned on the two sides of the voice coil 330, axial with the voice coil 330 respectively
It being fixedly connected, corresponding 360 outer ledge of vibrating diaphragm is provided with washer 380, annular groove is offered in the annular framework 310,
Fixed switching sliding block 370 is provided in the annular groove, both ends and the annular groove sidewall of the fixed switching sliding block 370 are set
It is equipped with buckle structure；The inside of the fixed corresponding vibrating diaphragm 360 of switching sliding block 370 is respectively arranged with extension, passes through tune
Position of the whole fixed switching sliding block 370 in the annular groove, so that the wherein fixed work of the vibrating diaphragm 360 of side,
The vibrating diaphragm 360 of the other side and 330 synchronizing moving of voice coil.
Earpiece that is to say loudspeaker, and working principle is varied, specifically include:
The first, moving-coil type, basic principle come from Fleming's Left Hand Rule, have the diatom of electric current vertical with the magnetic line of force one
Put magnet north and south interpolar into, conducting wire will by the magnetic line of force and both electric currents interaction and move, then a piece of vibrating diaphragm according to
It is attached on this root diatom, as curent change vibrating diaphragm just generates the movement of front and back.Current 90% or more cone basin monomer is all
The design of ring type.
The second, electromagnetic type, magnetic loudspeaker, also known as " inductor loudspeaker ", in magnetic loudspeaker structure, at permanent magnet the two poles of the earth
Between have the electromagnet of a movable core, when not having electric current in magnet spool, movable core is by two magnetic pole phase of permanent magnet
The attraction of grade attraction is remain stationary in center；When having electric current to flow through in coil, movable core is magnetized, and becomes one
Bar-shaped magnet.With the variation of current direction, the polarity of bar-shaped magnet also corresponding change makes movable core make rotation fortune around fulcrum
Dynamic, the vibration of movable core passes to vibrating diaphragm by cantilever and pushes air thermal vibration.
Third, 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.Do not exist together with electromagnetism is that inductance can
To regenerate lower frequency, but efficiency is but very low.
4th, electrostatic, basic principle is Coulomb's law, usually with the diaphragm of plastic colloid plus inductive materials such as aluminium
Vacuum vaporization processing, two diaphragms put face-to-face, when wherein it is a piece of add positive current high pressure when another will induce it is small
Electric current pushes air that can make a sound by attraction repulsive interaction each other.Electrostatic monomer is due to light weight and vibration
Disperse small, so being readily available as clear as crystal Hi-Mid, have an impact to bass power, and its is inefficient, uses
DC power supply is easy gather dust again.
5th, plane formula, the design that developed earliest by Japanese SONY, voice coil designs are still that moving-coil type is the theme, no
The plane diaphragm that cone basin vibrating diaphragm is changed to honeycomb structure is crossed, because of few people's cavity effect, characteristic is preferable, but efficiency is also relatively low.
6th, silk ribbon formula, not traditional voice coil designs, vibrating diaphragm are made of with very thin metal, and electric current flows directly into
Conductor makes its vibratory sound.Since its vibrating diaphragm is exactly voice coil, so quality is very light, performance reacts splendid, high frequency response
Very well.But the efficiency of silk ribbon speaker and Low ESR are always very big challenge to enlarger.Another way is that have sound
Circle, but voice coil is directly printed on plastic slice, it can solve the low-impedance problem in part in this way.
7th, horn-type, vibrating diaphragm pushes the air for being located at horn bottom and works, because not by diffusion institute when sound transmits
It is very high with efficiency, but shape due to bugle and length can all influence tone color, to replay low frequency and also be less susceptible to, now mostly
With in huge PA system or high pitch monomer.
8th, piezoelectric type, the loudspeaker to be worked using the inverse piezoelectric effect of piezoelectric material are known as piezoelectric speaker.Electricity is situated between
There is a phenomenon where polarization to make potential difference occur between two end surfaces under pressure for matter, referred to as " piezoelectric effect ".Its inverse effect
It answers, that is, elastic deformation can occur for the dielectric being placed in electric field, referred to as " inverse piezoelectric effect " or " electrostriction ".
9th, ionophone, ionophone are the protons for making air become electrification using electrion, impose exchange
After voltage these free charged molecules will due to vibration sounding, can be used only in the monomer of high frequency or more at present.Ion loudspeaking
Device and other loudspeakers are the difference is that without vibrating diaphragm, so transient response and high frequency characteristics are all fine, but structure is too complicated.
Tenth, air-flow modulates loudspeaker, also known as compressed-air loudspeaker.It is to make the energy using compressed air, utilizes audio-frequency electric
The loudspeaker of stream modulation air-flow sounding.It is made of gas chamber, modulation valve, horn and magnetic circuit.Compressed air is passed through by gas chamber
It crosses in valve, by additional modulates audio signals, the gas for making the fluctuation of air-flow change according to additional audio signal, while be modulated
Horn coupling is flowed through, to improve the efficiency of system.It is mainly used as the sound source or remote broadcast of high intensity noise environmental test
Deng.
11st, ultrasonic wave, it does not use the loudspeaker unit of any traditional form, but supersonic generator is utilized to produce
Ultrasonic beam of raw two beams Jing Guo specially treated, can be because mutual when the two wave beams act on the eardrum of human ear simultaneously
It acts on and generates the sense of hearing.
The earpiece of the present embodiment uses moving-coil type principle, drives vibrating diaphragm to make a sound by voice coil vibrations, in voice coil
Both ends have been all connected with a vibrating diaphragm, but two vibrating diaphragms are not while sounding works, when one of vibrating diaphragm is fixed sounding
