Description

Loudspeaker diaphragm structure

Technical Field

The utility model relates to a diaphragm, especially a speaker diaphragm structure.

Background

With the development of speakers, the performance requirements of speakers are higher and higher, and on the premise that the height of the speakers is not changed or reduced, the requirements on the material membranes for embodying the main performance of the speakers are higher and higher, and the thicknesses of the membranes are selected to be thinner and thinner.

The diaphragm is influenced by the thickness and the rigidity of the material, the diaphragm is easy to deform in the process of assembling the loudspeaker and gluing the frame body by the diaphragm folding edge, and glue is easy to overflow to the folding edge inner side of the diaphragm when the diaphragm folding edge is glued with the frame body, so that the loudspeaker is unbalanced in diaphragm vibration in work, and poor in tone quality and performance.

Disclosure of Invention

The utility model aims at providing a loudspeaker diaphragm structure takes place deformation phenomenon when preventing diaphragm hem veneer framework.

In order to realize the purpose, the utility model adopts the following technical scheme.

The utility model provides a speaker diaphragm structure, includes the diaphragm body, be formed with plane portion on the diaphragm body, it has the dome to bond on the plane portion, the edge all around of diaphragm body is formed with the hem parallel with plane portion, the inboard bonding of hem has the gasket.

Adopt aforementioned technical scheme the utility model discloses, through setting up the gasket, with the inboard of gasket laminating at the hem of diaphragm body, promote the thickness and the rigidity of hem through the gasket, prevent when the equipment diaphragm, hem veneer framework leads to the hem to warp or produce the fold, promotes the yields of equipment to avoid the diaphragm hem when gluing with the framework, glue overflows to the hem of diaphragm inboardly, promotes the speaker in the equilibrium of during operation diaphragm vibration, promotes tone quality.

Preferably, the whole diaphragm is rectangular, the length of the diaphragm body is 25 mm-40 mm, and the width of the diaphragm body is 9 mm-13 mm.

Preferably, the whole gasket is a rectangular ring, and the overall dimension of the gasket is the same as that of the folded edge.

The gasket is set to be in a rectangular structure the same as the folded edge, so that the gasket and the folded edge are completely overlapped, and the thickness and the strength of the folded edge are enhanced.

Preferably, the gasket is made of a non-metal material with the thickness of 0.1 mm-0.12 mm.

The thickness of the gasket is controlled within the range of 0.1 mm-0.12 mm, so that the assembly of the diaphragm on the frame body is prevented from being influenced, and the installation quality is prevented from being influenced.

Preferably, the non-metallic material can be made of high-strength plastic such as polyethylene naphthalate.

By adopting the material with higher strength, the strength of the folded edge can be enhanced by using the strength of the non-metallic material.

Preferably, the width of the shim is greater than the width of the hem.

The width setting of gasket makes the width of gasket be greater than the width of hem under the prerequisite that does not influence diaphragm installation and quality, can make the hem laminate completely on the gasket to promote the intensity of gasket through the width that increases the gasket, thereby increase the intensity of hem.

Preferably, the whole dome is rectangular, and the dome cover covers the middle part of the outer side of the plane part.

The beneficial effects of the utility model are that, through setting up the gasket, with the gasket laminating in the inboard of the hem of diaphragm body, promote the thickness and the rigidity of hem through the gasket, when preventing diaphragm assembling process, hem veneer framework leads to the hem to warp or produce the fold to avoid the diaphragm hem when gluing with the framework, glue is excessive to the hem inboard of diaphragm, promotes the speaker at the during operation diaphragm vibration equilibrium, promotes tone quality.

Detailed Description

The present invention will be further described with reference to the accompanying drawings, which are not intended to limit the scope of the embodiments described herein.

The utility model discloses a description reference numeral includes: dome 1, diaphragm body 2, hem 21, plane portion 22, gasket 3.

Referring to fig. 1 and 2, a speaker diaphragm structure includes a diaphragm body 2, a planar portion 22 is formed on the diaphragm body 2, a dome 1 is bonded on the planar portion 22, a folded edge 21 parallel to the planar portion 22 is formed on the peripheral edge of the diaphragm body 2, and a gasket 3 is bonded on the inner side of the folded edge 21.

Referring to fig. 1 and 2, the overall diaphragm is rectangular, and the length of the diaphragm body 2 is 25 mm-40 mm, and the width is 9 mm-13 mm.

Referring to fig. 3, the gasket 3 is a rectangular ring as a whole, and the outer dimension of the gasket 3 is the same as that of the folded edge 21. The gasket 3 is made of a non-metal material with the thickness of 0.1 mm-0.12 mm. The non-metallic material can adopt plastics such as polyethylene naphthalate and the like with higher strength.

Referring to fig. 3, the width of the shim 3 is greater than the width of the folded edge 21. With the width setting of gasket 3 under the prerequisite that does not influence the quality of diaphragm installation and diaphragm, make the width of gasket 3 be greater than the width of hem 21, can make hem 21 laminate completely on gasket 3 to promote the intensity of gasket 3 through the width that increases gasket 3, thereby increase hem 21's intensity.

Referring to fig. 1, the dome 1 is rectangular as a whole, and the dome 1 covers the middle of the outer side of the plane portion 22.

During assembly, the gasket 3 is firstly glued with the folded edge 21, and then the assembly with the gasket 3 is glued with the dome 1 to form a complete diaphragm.
