AI Technical Summary

Problems solved by technology

Due to the small bonding surface between the voice coil and the vibrating diaphragm, it is easy to cause rocking vibration between the voice coil and the vibrating diaphragm, especially when the speaker is working at a high power state, the rocking vibration will be more serious, resulting in poor sound quality. Seriously reduced, unable to meet the needs of large amplitude products

Embodiment 1

[0042] Figure 2A It is a top view of the special-shaped voice coil structure according to an embodiment of the present invention, Figure 2B yes Figure 2A Partial enlarged view of the special-shaped voice coil structure. Such as Figure 2A , Figure 2B As shown, the shaped voice coil 100 of the present invention includes two layers of coils wound together with wires, such as a first layer coil 101 and a second layer coil 201 , wherein the first layer coil 101 is rectangular or almost rectangular. The first layer coil 101 includes a first layer coil side portion 102 and a first layer coil corner portion 103 ; the second layer coil 201 includes a second layer coil side portion 202 and a second layer coil corner portion 203 .

[0043] Viewed from a direction perpendicular to the shaped voice coil 100, wherein the first layer coil side portion 102 is flush with the second layer coil side portion 202, and the second layer coil side portion 202 of the second layer coil 201 is ...

Embodiment 2

[0049] Embodiment 1 of the present invention is described in detail with the side portion 102 of the first layer coil being flush with the side portion 202 of the second layer coil. Figure 4 It is a top view of the special-shaped voice coil structure according to another embodiment of the present invention. Such as Figure 4 As shown, the present invention can also be implemented in the following manner, wherein the inner surface 206 of the second layer coil side portion 202 is kept flush with the inner surface 106 of the first layer coil side portion 102, and the second layer coil side portion The outer surface 207 of 202 is inwardly recessed relative to the outer surface 107 of the first-layer coil side portion 102 , so that a step 104 is also formed between the first-layer coil side portion 102 and the second-layer coil side portion 202 .

Embodiment 3

[0051] Embodiment 1 of the present invention is described in detail by taking the first-layer coil 101 as a rectangle or a rectangle-like shape. Figure 5A and Figure 5B It is a top view of the special-shaped voice coil structure in another embodiment of the present invention. Such as Figure 5A , Figure 5B As shown, the shape of the first layer coil 101 of the shaped voice coil 100 of the present invention can be a triangle, a five-pointed star or other polygonal shapes. Alternatively, it may be oval or circular.

Abstract

The invention provides a shaped voice coil, and a speaker and an electronic device using the same. The shaped voice coil includes at least two layers of coil layers wound, each of the coil layers includes a side portion and a corner portion; and the areas formed by being surrounded by adjacent two layers of the coil layers are different. The shaped voice coil provided by the invention can increasethe bonding area of the voice coil and the vibrating membrane, improve the bonding strength of the voice coil and the vibrating membrane, and can increase the ventilation of the four corners of the voice coil, and improve the heat dissipation effect of the voice coil.

Description

technical field [0001] The invention relates to a voice coil, in particular to a special-shaped voice coil, a loudspeaker and electronic equipment using the same. Background technique [0002] In recent years, with the rapid development of mobile communication technology and electronic equipment, more and more mobile communication equipment, such as mobile phones, handheld game consoles, laptop computers, multimedia players and other mobile terminals need to transmit audio signals. [0003] An electroacoustic product is a device that converts electrical energy into sound energy, and is usually called a loudspeaker or horn. Traditional loudspeakers generally include a frame, a magnetic circuit system installed in the frame, a voice coil movably accommodated in the magnetic circuit system, and a diaphragm installed on the frame. The voice coil and the diaphragm are connected to drive the diaphragm. The sheet vibrates, thereby producing sound. Among them, the voice coil is an...
