Background technology
Flexible film, coil and permanent magnet in loudspeaker, elastic film are similar with the effect of eardrum in human ear, and it is sent out
Sound, film can vibrate；Film is connected to coil, and it also has the effect for coil being retracted initial position except shock effect.When thin
When film vibrates, band moving winding vibration, the relative position change of coil and permanent magnet, this causes to become through the magnetic field of coil
Change, changes of magnetic field can produce induced electromotive force in coil, also just generate electric current.Specific sound has specific vibration,
Specific vibration produces the electric current of particular form.So loudspeaker just sound " coding " into electric current form.
The principle of receiver is the inverse process of loudspeaker, and structure is also about the same.Also there is a film in receiver, film is connected to
One coil, equally also there is a block permanent magnet.The electric current (such as microphone just " encodes " electric current for completing) of particular form flows through
The coil of receiver, the magnetic field for so allowing for coil generation changes, and then the distance of permanent magnet and coil can change.
Vibration of thin membrane has thus been driven, sound has been sent.
Current mobile phone, the direction of flat board development are to pursue ultra-thin portable, account for screen than big etc., and traditional mobile phone need to be equipped with one
Individual loudspeaker and receiver, most thin product thickness is 2.5mm (main flow 3.0mm) to Mobile phone horn on the market, and receiver most thin product is
2.0mm, although the placement that can stagger (i.e. upper, loudspeaker are under for receiver), but mobile phone component profile will be by when arrange
Elongate.
