Description
Technical field
Electroacoustic techniques field of the present invention, more particularly it relates to a kind of sound-producing device.
Background technology
Moving-coil type sound-producing device includes housing, magnetic circuit system, the vibrating diaphragm that is fixed together and voice coil loudspeaker voice coil etc..Voice coil loudspeaker voice coil includes voice coil loudspeaker voice coil
Body and a pair of lead wires, voice coil loudspeaker voice coil body are electrically connected by lead with external circuit.The lead drawn on voice coil loudspeaker voice coil body hangs
Sky is set.Vibrating diaphragm is fixed on housing.
Lead inevitably produces tractive force to voice coil loudspeaker voice coil, vibrating diaphragm.A pair of lead wires is typically drawn from the side of voice coil loudspeaker voice coil body
Go out, thus voice coil loudspeaker voice coil body, vibrating diaphragm include the opposite side of the outlet side and lead extraction location offside positioned at lead extraction location.
Because the tractive force that lead outlet side and opposite side are subject to is inconsistent, and then cause the amplitude of vibrating diaphragm both sides different, outlet side
Amplitude it is small, the amplitude of opposite side is big, so as to cause polarization.Polarization problem can cause product lead broken string, audition easily occur
Bad the problems such as.
And together with existing centring disk is each attached to lead outlet side and opposite side, it is impossible to solve inconsistent by tractive force
Caused vibrating diaphragm polarization problem.Outlet side is still different from the amplitude of opposite side.
Therefore, it is necessary to be improved to existing sound-producing device.
The content of the invention
It is an object of the present invention to provide a kind of new solution of sound-producing device.
According to an aspect of the invention, there is provided a kind of sound-producing device.The sound-producing device includes vibrational system and magnetic circuit
System, the vibrational system includes vibrating diaphragm and the voice coil loudspeaker voice coil being connected with the vibrating diaphragm, and the voice coil loudspeaker voice coil includes the voice coil loudspeaker voice coil of annular
Body and the lead drawn from the same side of the voice coil loudspeaker voice coil body；The voice coil loudspeaker voice coil body includes being located at lead extraction described in a pair
The outlet side of position and the opposite side relative with the outlet side；Branch piece is combined with the vibrating diaphragm, the branch piece includes position
In outermost edge part, positioned at the most pars intermedia of inner side and the connection pars intermedia and the supporting part of the edge part, institute
Support zone is stated in the side corresponding to the opposite side of the vibrating diaphragm.
Alternatively, the vibrating diaphragm includes central part, around the ring portion of the central part and the fixed part positioned at outermost；
The pars intermedia of the branch piece is combined with the central part of the vibrating diaphragm, the edge part of the branch piece and the fixed part phase of the vibrating diaphragm
With reference to.
Alternatively, the rounded rectangle in cross section of the voice coil loudspeaker voice coil body and pars intermedia, lead described in a pair is respectively from described
Draw two adjacent corners positions of voice coil loudspeaker voice coil body；Or, lead described in a pair is a pair of parallel from the voice coil loudspeaker voice coil body respectively
The same side end of straight flange is drawn.
Alternatively, one end of the supporting part is connected with a straight flange on the pars intermedia, the use on the pars intermedia
It is located at the same side with the opposite side in the straight flange being connected with the supporting part.
Alternatively, one end of the supporting part is connected with two adjacent corners positions of the pars intermedia respectively, it is described in
Between with the opposite side be located at the same side for two adjacent corners being connected with the supporting part in portion.
Alternatively, the lead of the voice coil loudspeaker voice coil is vacantly set.
Alternatively, the branch piece is fixed on a side surface of the vibrating diaphragm, and the voice coil loudspeaker voice coil body is fixed on the vibrating diaphragm
Another side surface on；Or, the vibrating diaphragm is fixed on a side surface of the branch piece, and the voice coil loudspeaker voice coil body is fixed on described
On another side surface of branch piece.
Alternatively, one end that the branch piece is fixed in the magnetic gap for stretching into the magnetic circuit system of the voice coil loudspeaker voice coil body.
Alternatively, the branch piece is made up of elastomeric material；Or the branch piece is copper foil.
Alternatively, the branch piece is flat member, and the edge part and pars intermedia are in the same plane；The supporting part
Position correspond to the opposite side of the voice coil loudspeaker voice coil body, and extending cloth in the plane with the edge part, pars intermedia
Put.
It was found by the inventors of the present invention that the side of voice coil loudspeaker voice coil body draws leaded, voice coil loudspeaker voice coil body, vibrating diaphragm include being used to draw
Go out the outlet side of lead and the opposite side positioned at outlet side offside.Because the power that outlet side and opposite side are subject to is inconsistent, and
Lead is adhered on vibrating diaphragm, and then causes the amplitude of vibrating diaphragm both sides different, and the amplitude of outlet side is small, and the amplitude of opposite side is big,
So as to cause vibrating diaphragm to polarize.Polarization problem can cause the problems such as lead broken string, Dysacousia easily occurs in product.Existing centering branch
Together with piece is each attached to outlet side and opposite side, thus outlet side is still different from the amplitude of opposite side, its can not solve by
Vibrating diaphragm polarization problem caused by lead tractive force is inconsistent.
Therefore, the technical assignment to be realized of the present invention or technical problem to be solved be those skilled in the art from
It is not expecting or it is not expected that, therefore the present invention is a kind of new technical scheme.
