Description
Technical Field
The invention belongs to the technical field of electroacoustic, and particularly relates to a sound production device.
Background
The moving-coil type sound generating device comprises a shell, a magnetic circuit system, a vibrating diaphragm, a voice coil and the like which are fixed together. The voice coil includes a voice coil body and a pair of leads, and the voice coil body is electrically connected with an external circuit through the leads. The lead wire that draws forth on the voice coil body sets up in the air. The vibrating diaphragm is fixed on the shell.
The lead inevitably produces traction force on the voice coil and the diaphragm. A pair of lead wires are generally led out from one side of the voice coil body, and thus the voice coil body and the diaphragm include a lead-out side at a lead-out position and an opposite side to the lead-out position. Because the traction force applied to the lead-out side is inconsistent with the traction force applied to the opposite side, the amplitudes of the two sides of the diaphragm are different, the amplitude of the lead-out side is small, and the amplitude of the opposite side is large, so that polarization is caused. The problem of polarization can cause the product to easily have the problems of lead wire disconnection, poor listening, and the like.
The existing centering support piece and the lead leading-out side and the opposite side are fixed together, so that the problem of diaphragm polarization caused by inconsistent traction force cannot be solved. The amplitude of the lead-out side is still different from the opposite side.
Therefore, there is a need for an improved sound emitting device.

Optionally, the diaphragm includes a central portion, a bending portion surrounding the central portion, and a fixing portion located at an outermost periphery; the middle part of the support piece is combined with the central part of the vibrating diaphragm, and the edge part of the support piece is combined with the fixing part of the vibrating diaphragm.
Optionally, the cross sections of the voice coil body and the middle part are rounded rectangles, and a pair of leads are led out from two adjacent corner positions of the voice coil body respectively; or, the pair of leads are respectively led out from the end part of the same side of the pair of parallel straight edges on the voice coil body.
Optionally, one end of the support portion is connected to one straight edge of the middle portion, and the straight edge of the middle portion for connecting to the support portion is located on the same side as the opposite side.
Optionally, one end of the supporting portion is connected to two adjacent corner positions of the middle portion, respectively, and two adjacent corners of the middle portion for connecting to the supporting portion are located on the same side as the opposite side.

Optionally, the support piece is a sheet-shaped member, and the edge part and the middle part are located on the same plane; the support part is arranged to extend on a plane corresponding to the edge part and the middle part, and corresponds to the opposite side of the voice coil body.
The inventor of the present invention found that a lead is led out from one side of the voice coil body, and the voice coil body and the diaphragm each include a lead-out side for leading out the lead and an opposite side located opposite to the lead-out side. Because the forces received by the leading-out side and the opposite side are inconsistent, and the lead is bonded on the vibrating diaphragm, the amplitudes of the two sides of the vibrating diaphragm are different, the amplitude of the leading-out side is small, and the amplitude of the opposite side is large, so that the vibrating diaphragm is polarized. The problem of polarization can cause the product to easily have the problems of lead wire disconnection, poor listening, and the like. The existing centering disk is fixed with the leading-out side and the opposite side, so that the amplitudes of the leading-out side and the opposite side are still different, and the problem of polarization of the diaphragm caused by inconsistent traction force of the lead wire cannot be solved.
Therefore, the technical task to be achieved or the technical problems to be solved by the present invention are never thought or anticipated by those skilled in the art, and therefore the present invention is a new technical solution.
