Description

Technical Field

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

[0002] Currently, voice coil windings are generally made of copper or aluminum wire. Under the same power conditions, copper wire usually needs to be wound in four layers to achieve the same effect, while aluminum wire only needs to be wound in three layers to achieve the same effect. Moreover, aluminum wire is cheaper, so aluminum wire is generally used as the winding material.

[0003] However, when using aluminum wire winding, although theoretically only three layers are needed, an additional layer of return wire is required, resulting in the aluminum wire only being wound in four layers, thus failing to achieve true material savings. Therefore, a material-saving voice coil skeleton is proposed to solve the above problems. Summary of the Invention

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

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

[0006] A material-saving voice coil skeleton includes a skeleton body, a first conductive plate and a second conductive plate fixedly connected to the outer side of the skeleton body, two clearance openings are opened inside the first adhesive paper, and the tops of the second conductive plate and the first conductive plate are respectively located inside the clearance openings, the outer side of the skeleton body is provided with insulating paper, the bottom of the insulating paper is provided with clearance groove, and the bottom end of the first conductive plate is located inside the clearance groove.

[0007] As a further embodiment of this utility model, a first adhesive paper is fixedly connected to the outer circumferential wall of the skeleton body, and the first adhesive paper is in contact with the first conductive plate.

[0008] As a further embodiment of this invention, the insulating paper is located outside the first adhesive paper, and the insulating paper covers the first adhesive paper.

[0009] As a further improvement of this invention, the first conductive plate has a T-shaped structure.

[0010] As a further embodiment of this utility model, it also includes a first through hole, which is opened at the bottom of the skeleton body and the insulating paper. A second adhesive paper is fixedly connected to the inner side of the skeleton body, and the second adhesive paper covers the second through hole and the first through hole.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. This utility model not only enables precise control of the coil winding on the skeleton body through the combined use of the first conductive plate and the second conductive plate, but also avoids the waste of materials caused by winding excess coils, thus saving resources.

[0013] 2. The present invention not only facilitates the fixing of the first conductive plate by means of the first adhesive paper, thereby making the first conductive plate more stable, but also isolates the coil of the winding part from contact with the first conductive plate, thus improving the protective effect of the device.

[0014] 3. By using the first through hole and the second through hole together, the end of the coil after multiple layers of winding extends upward along the height of the skeleton body and is fixed to the guide plate, avoiding the need to wind the coil again when fixing the end, which would lead to waste and improve the use effect of the device.

[0021] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of the present application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate, so that all other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative effort should fall within the scope of protection of the present application. Example

[0022] Reference Figures 1-3 A material-saving voice coil frame includes a frame body 1. A first conductive plate 4 and a second conductive plate 5 are adhered to the outside of the frame body 1. Two recessed openings 2 are formed inside the first adhesive paper 7, and the tops of the second conductive plate 5 and the first conductive plate 4 are respectively located inside the recessed openings 2. An insulating paper 3 is adhered to the outside of the frame body 1, and a recessed groove 6 is formed at the bottom of the insulating paper 3. The bottom end of the first conductive plate 4 is located inside the recessed groove 6. When it is necessary to wind the coil, one end of the coil is soldered to the middle position of the surface of the second conductive plate 5. The coil is wound around the outside of the frame body 1, starting from the bottom of the second conductive plate 5, until the bottom of the frame body 1. This is one layer of coil. Then, the second layer of coil is wound upwards, and the third layer of coil is wound downwards. At this time, the end of the coil is located at the bottom of the frame body 1. Finally, the end of the coil is soldered to the bottom end of the first conductive plate 4, thereby enabling precise control of the coil and avoiding the waste of materials caused by using excess coil.

[0023] In this utility model, it should be noted that a first adhesive paper 7 is adhered to the outer circumference of the skeleton body 1, and the first adhesive paper 7 is in contact with the first conductive plate 4. The first adhesive paper 7 facilitates the fixation of the first conductive plate 4, thereby making the first conductive plate 4 more stable. It can also isolate the contact between the coil of the winding part and the first conductive plate 4. The insulating paper 3 is located outside the first adhesive paper 7. The insulating paper 3 covers the first adhesive paper 7 and makes the outer side of the skeleton body 1 insulated. The first conductive plate 4 has a T-shaped structure.

[0024] The working principle of this embodiment is as follows: In use, the first conductive plate 4 and the second conductive plate 5 are first bonded to the outside of the skeleton body 1, and the first conductive plate 4 and the skeleton body 1 are further fixed by the first adhesive paper 7. Then, the insulating paper 3 is bonded to the outside of the skeleton body 1. Then, one end of the coil is soldered to the middle position of the surface of the second conductive plate 5. The coil is wound around the outside of the skeleton body 1, starting from the bottom of the second conductive plate 5, until the bottom of the skeleton body 1. Then, the second layer of coil is wound upwards, and the third layer of coil is wound downwards. At this time, the end of the coil is located at the bottom of the skeleton body 1. Finally, the end of the coil is soldered to the bottom of the first conductive plate 4. Example

[0025] Reference Figures 4-5 A material-saving voice coil frame further includes a first through hole 8, which is opened at the bottom of the frame body 1 and the insulating paper 3. A second adhesive paper 9 is glued to the inner side of the frame body 1. The second adhesive paper 9 can position the part of the wound coil extending along the inner wall of the frame body 1, preventing the coil from easily falling off under force. The second adhesive paper 9 also blocks the second through hole 10 and the first through hole 8. A second conductive plate 5 away from the second through hole 10 is selected, and one end of the coil is soldered to the middle position of the outer surface of the second conductive plate 5. Then the coil is wound around the outside of the frame body 1, starting from the bottom of the second conductive plate 5, until the bottom of the frame body 1. This is the first layer of coil. Then the coil is wound upward to form the second layer of coil, and then wound downward to form the third layer of coil. At this time, the end of the coil is located at the bottom of the frame body 1. Then the end of the coil passes through the first through hole 8 and extends upward along the height of the frame body 1 into the second through hole 10, and is soldered to another second conductive plate 5.

[0026] The working principle of this embodiment is as follows: When it is necessary to wind the coil, firstly, one end of the coil is soldered to the middle position of the surface of a second conductive plate 5. Then, the coil is wound around the outside of the skeleton body 1, starting from the bottom of the second conductive plate 5 and continuing until the bottom of the skeleton body 1. This is the first layer of coil. Then, continue to wind upward to form the second layer of coil, and then wind downward to form the third layer of coil. At this time, the end of the coil is located at the bottom of the skeleton body 1. Then, the end of the coil passes through the first through hole 8 and extends upward along the height of the skeleton body 1 into the second through hole 10, and is soldered to another second conductive plate 5. Finally, the coil extending along the inner wall of the skeleton body 1 is positioned by the second adhesive paper 9.
