Description
Technical field
The present invention relates to speaker technology field, and in particular to a kind of mobile phone ultrathin loudspeaker.
Background technology
At present, known loudspeaker is that generation is dynamic after magnetic force is changed into after being powered by voice coil loudspeaker voice coil by between washer generation magnetic gap
Power, vibrating diaphragm is driven to send sound, but this tune needs extra washer and voice coil loudspeaker voice coil, this allows for of loudspeaker itself
Volume is larger, increasingly tends to lightening design for current mobile phone, this is insufficient for, and lacks one on the market at present
Kind loudspeaker can reduce voice coil loudspeaker voice coil and washer so as to meet lightening design.
The content of the invention
To solve above-mentioned problem, the present invention provides a kind of mobile phone ultrathin loudspeaker, eliminates traditional conventional loudspeakers
Voice coil loudspeaker voice coil and washer, set turn into conductive diaphragm, so as to substitute voice coil loudspeaker voice coil, greatly reduce the thickness of original loudspeaker, realization
The lightening design of mobile phone, realizes mechanical production line balance.
A kind of mobile phone ultrathin loudspeaker, including U iron, U iron inside hollow out form cavity, and the inside cavity is placed with
Magnet, the U iron are nested in internal stent, and the stent outer is inserted with shell fragment and fixed by gluing, the shell fragment and conduction
The external part of vibrating diaphragm mutually welds, and is provided with protecting cover above the support, conductive diaphragm is provided between the protecting cover and support, described
Conductive diaphragm is fixed on inside protecting cover with glue, and the protecting cover surrounding is connected by glue with support surrounding, the conductive diaphragm
Including coil and fpc film, the coil is fixed on the centre position of fpc film by glue.
Preferably, the U Tie Tongs cross glue and are connected with magnet.
Preferably, the support is fixed by glue and U iron phases.
Preferably, the coil in the conductive diaphragm can produce magnetic field upon power-up.
Preferably, the material of the conductive diaphragm is PET.
Preferably, the conductive diaphragm itself being capable of up-down vibration.
Beneficial effects of the present invention：The voice coil loudspeaker voice coil and washer of traditional conventional loudspeakers are eliminated, set turns into conductive diaphragm, passed through
Coil in conductive diaphragm produces magnetic field upon power-up, and so as to substitute voice coil loudspeaker voice coil, the conductive diaphragm in loudspeaker can pass through electricity
Stream, in loudspeaker in the presence of magnet, vibration is produced, because conductive diaphragm compares with traditional washer with voice coil loudspeaker voice coil, significantly
Ground reduces the thickness of original loudspeaker, can realize the lightening of mobile phone speaker, so that Cell Phone Design is more frivolous,
Set turns into conductive diaphragm so that loudspeaker simplified manufacturing process, mechanical production line balance can be achieved, be produced into so as to reduce
This..

Embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, it is right below in conjunction with drawings and Examples
The present invention is further elaborated.It should be appreciated that specific embodiment described herein only to explain the present invention, not
For limiting the present invention.
As shown in Figure 1, Figure 2 and Figure 3, a kind of mobile phone ultrathin loudspeaker, including U iron 5, the inside hollow out of U iron 5 form chamber
Body, the inside cavity are placed with magnet 4, and the U iron 5 is nested in inside support 3, and the outside of support 3 is inserted with shell fragment 6 and led to
Cross gluing to fix, the shell fragment 6 mutually welds with the external part of conductive diaphragm 2, and the top of support 3 is provided with protecting cover 1, the shield
Conductive diaphragm 2 is provided between lid 1 and support 3, the conductive diaphragm 2 is fixed on inside protecting cover 1 with glue, the surrounding of protecting cover 1
It is connected by glue with the surrounding of support 3, the conductive diaphragm 2 includes coil and fpc film, and the coil is fixed on by glue
The centre position of fpc film.
As shown in Figure 1, Figure 2 and Figure 3, the U iron 5 is connected by glue with magnet 4, and the support 3 passes through glue and U iron
5 phases are fixed, and the coil in the conductive diaphragm 2 can produce magnetic field upon power-up, and the material of the conductive diaphragm 2 is PET,
The conductive diaphragm 2 itself can up-down vibration, in actual moving process, the external part of conductive diaphragm 2 is two wires point
Not Han Jie loudspeaker shell fragment 6 positive pole and negative pole, when electric current is passed to conductive diaphragm 2 by the positive pole and negative pole of loudspeaker shell fragment 6
When, magnetic field is produced because there are many coils in conductive diaphragm 6, produces and is attracted or repelled with the magnetic field of the magnet 4 in loudspeaker, lead
Electric vibrating diaphragm 2 produces the effect that vibration reaches sounding.
The present invention eliminates the voice coil loudspeaker voice coil and washer of traditional conventional loudspeakers, and set turns into conductive diaphragm 2, passes through conductive diaphragm 2
In coil produce magnetic field upon power-up, so as to substitute voice coil loudspeaker voice coil, the conductive diaphragm 2 in loudspeaker can raised by electric current
In sound device in the presence of magnet, vibration is produced, because conductive diaphragm 2 compares with traditional washer with voice coil loudspeaker voice coil, is greatly reduced
The thickness of original loudspeaker, can realize the lightening of mobile phone speaker, so that Cell Phone Design is more frivolous；Tradition is raised
The processing of sound device washer and voice coil loudspeaker voice coil is more troublesome, and the present invention eliminates the voice coil loudspeaker voice coil and washer of traditional conventional loudspeakers, assembles
For conductive diaphragm so that loudspeaker simplified manufacturing process, mechanical production line balance can be achieved, so as to reduce production cost.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
Any modification, equivalent substitution or improvement made within refreshing and principle etc., should be included in the scope of the protection.
