Problems solved by technology

[0013] Solve the problem that when the strut vibrates, the deformation mainly occurs at the root, and the middle cantilever body participates in little deformation, so that when the strut vibrates, both the root and the middle part of the cantilever participate in the deformation, reducing the stress on the root of the cantilever , improve the anti-fatigue performance of the damper, and the production process is simple, no additional consumption of substrates and conductive materials is required, and the production cost is low

Embodiment 1

[0042] A centering strut, which adopts a multi-layer structure composed of multiple material layers or a multi-layer structure composed of multiple material layers and glue layers. The material layer includes a conductive layer located in the central area and a conductive layer located on the outer surface. Substrate layer, the substrate layer can be polyimide (PI) film, the conductive layer can be copper foil, the copper foil is adhered to the polyimide film coated with adhesive by rolling process, or no The adhesive produces copper foil directly on the polyimide film.

[0043]The substrate layer is not limited to the above-mentioned polyimide film, and other polymer material films other than polyimide can also be selected, and the conductive layer is not limited to the above-mentioned copper foil, and can also be other metals. layer or graphene conductive layer, etc.

[0044] Taking the described damper as an example of a six-layer layered structure for illustration, in thi...

[0071] The same part as that of Embodiment 1 has been discussed in detail in Embodiment 1, and will not be repeated here. Compared with Embodiment 1, this embodiment is modified as follows:

[0072] preferred, such as image 3 As shown, the first cantilever unit 1 , the second cantilever unit 2 , the third cantilever unit 3 , the fourth cantilever unit 4 and the fifth cantilever unit 5 are distributed symmetrically with respect to the center line of the cantilever body 8 .

[0073] The shape of the first cantilever unit 1, the second cantilever unit 2, the fourth cantilever unit 4 and the fifth cantilever unit 5 is trapezoidal, and the shape of the third cantilever unit 3 is symmetrical to the center line of the cantilever body 8. Narrow shape in the middle.

[0074] The length L1 of the first cantilever unit 1 is the same as the length L5 of the fifth cantilever unit 5, the length L2 of the second cantilever unit 2 is the same as the length L4 of the fourth cantilever unit 4...

Embodiment 3

[0086] The same part as that of Embodiment 1 has been discussed in detail in Embodiment 1, and will not be repeated here. Compared with Embodiment 1, this embodiment is modified as follows:

[0087] preferred, such as Figure 4 As shown, the first cantilever unit 1 , the second cantilever unit 2 , the third cantilever unit 3 , the fourth cantilever unit 4 and the fifth cantilever unit 5 are asymmetrically distributed with respect to the center line of the cantilever body.

[0088] The shape of the first cantilever unit 1, the second cantilever unit 2, the fourth cantilever unit 4 and the fifth cantilever unit 5 is trapezoidal, and the shape of the third cantilever unit 3 is symmetrical to the center line of the cantilever body 8. Narrow shape in the middle.

[0089] The length L1 of the first cantilever unit 1 is the same as the length L5 of the fifth cantilever unit 5, the length L2 of the second cantilever unit 2 is the same as the length L4 of the fourth cantilever unit 4,...

Abstract

The invention discloses a centering disk which is of a multi-layer structure formed by compositing a plurality of material layers or of a multi-layer structure formed by compositing a plurality of material layers and a glue layer. The material layers comprise a conductive layer located in the center area and a base material layer located on the outer surface; the centering disk comprises a connecting cantilever, the connecting cantilever comprises roots and a cantilever body, and the roots are located at the two ends of the cantilever body; the cantilever body comprises a plurality of cantilever units formed by cutting off base material layers with different lengths. The centering disk has the advantages that the problems that when the centering disk vibrates, deformation mainly occurs atthe root, the deformation participated by the middle cantilever body is little, and a copper layer in the centering disk is broken due to the fact that the stress at the bent position of the root is too large are solved.

Description

technical field [0001] The invention relates to a centering strut and a loudspeaker with the same, belonging to the field of electroacoustic technology. Background technique [0002] The existing ultra-linear loudspeaker includes: auxiliary system, magnetic circuit system and vibration system, the magnetic circuit system is provided with a magnetic gap, the vibration system includes a diaphragm, a centering strut and a voice coil combined with the diaphragm, and the voice coil is arranged on In the magnetic gap, the current change in the voice coil arranged in the magnetic gap causes the voice coil to vibrate under the action of the magnetic field force, driving the diaphragm to vibrate and produce sound. The centering strut is one of the basic components of the super linear loudspeaker. Its function is mainly to ensure the correct position of the voice coil in the magnetic gap, to keep the voice coil under force, and the vibration system only reciprocates along the axial di...
