Description

Technical Field

[0001] This utility model relates to the field of voice coil skeleton technology, and in particular to a composite voice coil skeleton. Background Technology

[0002] The voice coil is directly defined as the coil through which current flows in a loudspeaker. It is an important component of the mechanical wave system of an electrodynamic loudspeaker, and can be considered the heart of the loudspeaker. The voice coil frame serves to support the voice coil.

[0003] Existing voice coils have poor heat dissipation. The skeleton material used is film, which has the characteristics of low temperature resistance, low strength, insufficient rigidity, and large expansion coefficient. When the arrangement is flat or square wires, the heat and gas generated by the voice coil are difficult to dissipate, causing the voice coil to burn out and become unusable. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a composite voice coil skeleton.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A composite voice coil skeleton includes a skeleton body, the skeleton body comprising a metal layer and a film layer, an adhesive layer being disposed between the metal layer and the film layer to bond the metal layer and the film layer, and a plurality of staggered first heat dissipation holes and second heat dissipation holes being provided on the outer side of the skeleton body.

[0007] As a further embodiment of this utility model, the inner wall of the frame body is provided with a plurality of air passage grooves that connect adjacent first heat dissipation holes and second heat dissipation holes.

[0008] As a further embodiment of this utility model, the inner wall of the frame body is provided with a plurality of ventilation grooves that connect two adjacent first heat dissipation holes and second heat dissipation holes.

[0009] As a further improvement of this utility model, it also includes a plurality of third heat dissipation holes, which are all opened on the outer side of the frame body and are evenly distributed.

[0010] As a further improvement of this invention, all of the third heat dissipation holes are square.

[0011] As a further embodiment of this utility model, it also includes a plurality of fourth heat dissipation holes, which are evenly opened on the outer side of the frame body, and a plurality of fifth heat dissipation holes are opened on the outer side of the frame body at positions between two adjacent fourth heat dissipation holes.

[0012] As a further embodiment of this invention, the fourth heat dissipation hole is square, and all of the plurality of fifth heat dissipation holes are circular.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. By setting up an adhesive layer, which is a high-temperature resistant hot melt adhesive, the skeleton film and metal materials are bonded together. In addition, heat dissipation holes are set in the structural design to achieve good heat dissipation performance.

[0015] 2. By using the air passage slot and the ventilation slot together, the first heat dissipation hole and the second heat dissipation hole can be connected to each other, thereby increasing the airflow on the frame body and further improving the heat dissipation performance.

[0022] Reference Figures 1-2 A composite voice coil skeleton includes a skeleton body 1, which comprises a metal layer 8 and a film layer 6. The metal layer 8 is made of steel, and an adhesive layer 7 is provided between the metal layer 8 and the film layer 6 to bond them together. The adhesive layer 7 is made of high-temperature resistant hot melt adhesive. Multiple staggered first heat dissipation holes 4 and second heat dissipation holes 5 are provided on the outer side of the skeleton body 1. The metal layer 8 is supported by steel through a casting process. Then, high-temperature resistant hot melt adhesive is applied to the outer side of the metal layer 8 to form the adhesive layer 7. The film layer 6 is then bonded to the outer side of the metal layer 8 through the adhesive layer 7 to form the skeleton body 1. The multiple staggered first heat dissipation holes 4 and second heat dissipation holes 5 are then provided on the skeleton body 1 to achieve good heat dissipation performance.

[0023] In this invention, the inner wall of the frame body 1 is provided with a plurality of air passage grooves 2 that connect adjacent first heat dissipation holes 4 and second heat dissipation holes 5, and the inner wall of the frame body 1 is provided with a plurality of ventilation grooves 3 that connect two adjacent first heat dissipation holes 4 and second heat dissipation holes 5. The air passage grooves 2 and ventilation grooves 3 that connect the first heat dissipation holes 4 and second heat dissipation holes 5 are opened inside the frame body 1 to increase the air circulation on the frame body 1 and further improve the heat dissipation performance.

[0024] The working principle of this embodiment is as follows: In use, steel is used as the material to support the metal layer 8 through a casting process. Then, high-temperature resistant hot melt adhesive is coated on the outside of the metal layer 8 to form an adhesive layer 7. Then, the film layer 6 is bonded to the outside of the metal layer 8 through the adhesive layer 7 to form the skeleton body 1. Then, multiple staggered first heat dissipation holes 4 and second heat dissipation holes 5 are opened on the skeleton body 1 to achieve good heat dissipation performance. At the same time, air passage grooves 2 and ventilation grooves 3 are opened inside the skeleton body 1 to connect the first heat dissipation holes 4 and the second heat dissipation holes 5, increasing the air circulation on the skeleton body 1 and further improving the heat dissipation performance. Example

[0025] Reference Figure 3 A composite voice coil skeleton also includes multiple third heat dissipation holes 9, which are all opened on the outside of the skeleton body 1 and are evenly distributed. All the multiple third heat dissipation holes 9 are square.

[0026] The working principle of this embodiment is as follows: When in use, the heat dissipation hole is set as a square third heat dissipation hole 9, which can increase the space for air flow. Example

[0027] Reference Figure 4A composite voice coil skeleton also includes a plurality of fourth heat dissipation holes 10. The plurality of fourth heat dissipation holes 10 are evenly opened on the outer side of the skeleton body 1. A plurality of fifth heat dissipation holes 11 are opened on the outer side of the skeleton body 1 between two adjacent fourth heat dissipation holes 10. The fourth heat dissipation holes 10 are square and the plurality of fifth heat dissipation holes 11 are all circular.

[0028] The working principle of this embodiment is as follows: In use, the heat dissipation holes are set as a square fourth heat dissipation hole 10 and a circular fifth heat dissipation hole 11, and the fifth heat dissipation hole 11 is located between two adjacent fourth heat dissipation holes 10, thereby further increasing the space for airflow.
