Description
Technical Field
The invention belongs to the technical field of electroacoustic technology, and in particular relates to a sound generating 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 to an external circuit through the leads. Lead wires led out from the voice coil body are suspended. The vibrating diaphragm is fixed on the shell.
The leads inevitably generate traction force on the voice coil and the diaphragm. A pair of leads are typically routed from one side of the voice coil body, and thus the voice coil body, diaphragm, includes a lead-out side at the lead-out location and an opposite side opposite the lead-out location. Since the traction force applied to the lead-out side and the opposite side is inconsistent, the vibration amplitudes of the two sides of the vibrating diaphragm are different, the vibration amplitude of the lead-out side is small, and the vibration amplitude of the opposite side is large, so that polarization is caused. The polarization problem can cause that the product is easy to have the problems of wire breakage, poor hearing and the like.
The existing centering support piece is fixed with the lead-out side and the opposite side of the lead, so that the problem of vibration film polarization caused by inconsistent traction force cannot be solved. The amplitude of the extraction side is still different from the opposite side.
Therefore, there is a need for improvements over existing sound emitting devices.
Disclosure of Invention
An object of the present invention is to provide a new solution for a sound generating device.
According to one aspect of the present invention, a sound emitting device is provided. The sound generating device comprises a vibration system and a magnetic circuit system, wherein the vibration system comprises a vibrating diaphragm and a voice coil fixedly connected with the vibrating diaphragm, and the voice coil comprises an annular voice coil body and leads led out from the same side of the voice coil body; the voice coil body comprises a leading-out side positioned at a pair of lead-out positions and an opposite side opposite to the leading-out side; the vibrating diaphragm is combined with a support piece, the support piece comprises an edge part positioned at the outermost side, a middle part positioned at the innermost side and a supporting part connected with the middle part and the edge part, and the supporting part is positioned at one side of the vibrating diaphragm corresponding to the opposite side.
Optionally, the vibrating diaphragm includes a central portion, a ring-folded portion surrounding the central portion, and a fixing portion located at the 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 fixed part of the vibrating diaphragm.
Optionally, the cross sections of the voice coil body and the middle part are round-corner rectangles, and a pair of leads are respectively led out from two adjacent corner positions of the voice coil body; or, a pair of leads are led out from the same side end parts of a pair of parallel straight sides on the voice coil body.
Optionally, one end of the supporting portion is connected to one straight edge on the middle portion, and the straight edge on the middle portion for connection to the supporting 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, and two adjacent corners of the middle portion for connection to the supporting portion are located on the same side as the opposite side.
Optionally, the lead wire of voice coil is unsettled to set up.
Optionally, the support piece is fixed on one side surface of the vibrating diaphragm, and the voice coil body is fixed on the other side surface of the vibrating diaphragm; or the vibrating diaphragm is fixed on one side surface of the support sheet, and the voice coil body is fixed on the other side surface of the support sheet.
Optionally, the support piece is fixed at one end of the voice coil body, which extends into the magnetic gap of the magnetic circuit system.

Optionally, the supporting piece is a sheet-shaped member, and the edge part and the middle part are positioned on the same plane; the support portion is positioned corresponding to the opposite side of the voice coil body and extends on a plane lying with the edge portion, the intermediate portion.
The inventor of the present invention found that a lead wire is led out from one side of the voice coil body, and that the voice coil body and the diaphragm each include an led-out side for leading out the lead wire and an opposite side located opposite to the led-out side. Because the forces received by the leading-out side and the opposite side are inconsistent, and the leads are adhered to the vibrating diaphragm, the vibration amplitudes at the two sides of the vibrating diaphragm are different, the vibration amplitude at the leading-out side is small, and the vibration amplitude at the opposite side is large, so that the vibrating diaphragm is polarized. The polarization problem can cause that the product is easy to have the problems of wire breakage, poor hearing and the like. The existing centering support piece 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 vibration film polarization caused by inconsistent lead traction force cannot be solved.
The technical task to be achieved or the technical problem to be solved by the present invention is therefore a new technical solution, which has never been conceived or not yet been contemplated by the person skilled in the art.
In the sound generating device provided by the invention, a gap is formed between the middle part and the edge part of the support piece, the support part is positioned between the middle part and the edge part, and the middle part is connected with the edge part through the support part.

The voice coil body 140 includes an extraction test at an extraction position of the lead 141 and an opposite side opposite to the extraction side. The lead-out side and the opposite side are disposed opposite to each other on the voice coil body 140. The pair of lead wires 141 are led out from the lead-out side.
When the magnetic circuit system drives the voice coil 14 to vibrate, the lead-out side receives larger traction force of the lead wire 141, and the amplitude is smaller. The opposite side is not subject to the pulling force of the lead 141 or is subject to the pulling force of the lead 141 being smaller and the amplitude being larger.
Referring to fig. 4 and 8, a support 12 is attached to the diaphragm 13. The support 12 includes an outermost edge 122, an innermost middle 120, and a support 121 connecting the middle 120 and the edge 122.

The diaphragm 13 is combined with the support 12. Preferably, the diaphragm 13 includes a central portion 130, a folded ring portion 131 surrounding the central portion 130, and a fixing portion 132 located at the outermost periphery. The fixing portion 132 extends outwardly from the hinge portion 131. The diaphragm 13 is fixedly disposed by the fixing portion 132. The middle portion 120 of the support 12 is coupled to the central portion 130 of the diaphragm 13. The edge portion 122 of the support 12 is combined with the fixing portion 132 of the diaphragm 13. The voice coil body 140 may be connected and fixed to the central portion 130 of the diaphragm 13.
The voice coil body 140, the central portion 130 of the diaphragm 13 and the middle portion 120 of the support 12 are combined together. The edge portion 122 of the support 12 is combined with the fixing portion 132 of the diaphragm 13.

The other side of the middle portion 120, which is far away from the direction of the supporting portion 121, is relatively suspended, and is connected to the lead-out side of the voice coil body 140, and the supporting sheet 12 has weak supporting and traction effects on the lead-out side of the voice coil body 140.
In this way, the support piece 12 can adjust the vibration balance between the lead-out side and the opposite side of the voice coil body 140.
The intermediate portion 120 of the support 12 can have a variety of shapes.
In one example, referring to fig. 2 and 4, the cross-section of the voice coil body 140 and the middle portion 120 of the support 12 is rounded rectangular. The rounded rectangle comprises four straight sides and four corners connecting the four straight sides end to end. For example, a pair of the leads 141 may extend in a direction parallel to the long axis of the voice coil body 140.
