Embodiment 1

[0083] Such as Figure 1A As shown, this embodiment provides a voice coil combination, specifically a double voice coil self-adhesive combination arranged up and down. In this double voice coil combination, the combination of the two is a self-adhesive combination between the wired surface and the wireless surface. Specifically, the first bonding surface 110 can be the wired surface of the first voice coil 11, the second bonding surface 120 can be the wireless surface of the second voice coil 12, or the first bonding surface 110 can be the wireless surface of the first voice coil 11, and the second bonding surface 120 can be the wireless surface of the first voice coil 11. The two bonding surfaces 120 are wired surfaces of the second voice coil 12 .

[0084] On the other hand, the shape of the voice coil can be circular, rectangular and other desired shapes, please refer to Figure 1A As shown, but not limited to, square voice coils can be utilized Figure 1A It is obtained ...

Embodiment 2

[0114] This embodiment proposes another self-adhesive glued voice coil combination, please combine Figure 1B As shown, the voice coil combination of this embodiment still takes double voice coils as an example, the first joint surface 110 is the wireless surface of the first voice coil 11, and the second joint surface 120 is the wireless surface of the second voice coil 12, also That is to say, the wireless surfaces of the first voice coil 11 and the second voice coil 12 are connected to form a self-adhesive composite voice coil assembly.

[0115] The parts in this embodiment that are the same as those in the previous embodiment will not be repeated. For example, the structure of the single voice coil, the additional structure and the same parts in the winding machine, please combine the content of the previous embodiment, and only the different parts will be described below.

[0116] The voice coil combination of the wireless surface self-adhesive combination of two voice co...

Embodiment 3

[0130] This embodiment proposes another self-adhesive glued voice coil combination, please combine Figure 1C As shown, the voice coil combination of this embodiment still takes double voice coils as an example, the first joint surface 110 is the wired surface of the first voice coil 11, and the second joint surface 120 is the wired surface of the second voice coil 12, also That is to say, the wired surfaces of the first voice coil 11 and the second voice coil 12 are connected to form a self-adhesive composite voice coil combination. The parts in this embodiment that are the same as the previous two embodiments will not be repeated, such as the structure of a single voice coil, the additional structure and the same parts in the winding machine, please combine the content of the previous embodiment, and only describe the different parts below .

[0131] Such as Figure 9 As shown, the additional structure in this embodiment not only includes the additional structure in any on...

Abstract

Embodiments of the present invention provide a voice coil assembly, a manufacturing method, a loudspeaker, a wire winding device and an additional structure thereof, the voice coil assembly includes at least two voice coils combined by self-adhesive means; the wire winding device includes a wire machine, the winding machine includes a winding device, the winding device includes a mandrel, and the winding device also includes an additional structure that cooperates with the winding device, for winding the first voice coil A second voice coil is wound on the bobbin mandrel to form a self-adhesive glued voice coil assembly. Using the above-mentioned solution, the step of gluing can be omitted, so that ordinary inserts can be used satisfactorily, and the height of the voice coil is good, the concentricity of the voice coil is extremely high, the beat is accelerated, and mass production is easy to achieve.

Description

technical field [0001] The invention relates to the field of loudspeakers, in particular to a voice coil combination, a manufacturing method, a loudspeaker, a wire winding device and an additional structure thereof. Background technique [0002] A loudspeaker is a transducer device that converts electrical signals into acoustic signals. The voice coil is forced to move in a magnetic field when it is energized, thereby driving the diaphragm to vibrate and producing sound. In the prior art loudspeaker in the sensor working mode, the coil of the loudspeaker is used to sense the induced electric signal, and the sensor signal is processed based on the mathematical model of the loudspeaker, so as to obtain the position information of the voice coil. The disadvantage of these solutions is that dynamic loudspeaker parameters are not available. [0003] Using two coils in series, the coil reciprocates in the magnetic gap after the alternating current is passed through. After the coi...
