Description

Technical Field

[0001] The utility model relates to the technical field of voice coils, in particular to a shockproof voice coil. Background Art

[0002] The voice coil and the diaphragm are important components of the speaker. The diaphragm is bonded to one end of the voice coil frame. The voice coil is subjected to force in the magnetic field, which drives the diaphragm to vibrate. In traditional speakers, the voice coil vibrates, but the magnetic cylinder magnet does not vibrate, which produces sound. For speakers on vibrators, the magnetic cylinder magnet and the voice coil are integrated. The voice coil does not vibrate, and the entire combination produces a vibration effect. The positive and negative poles of the voice coil used on existing vibrators are both coil leads or soldered wires are welded on the coil leads. Since the amplitude of the vibrator is very large, the coil leads and the solder wires cannot bear the huge amplitude, which causes problems such as broken wires and circuit breaks, affecting the normal operation of the vibrator. Summary of the invention

[0003] The problem to be solved by the utility model is to provide a shockproof voice coil to avoid the problem of wire breakage and improve the working reliability of the voice coil.

[0004] To solve the above technical problems, a shock-proof voice coil is provided according to the utility model, comprising a skeleton and a coil, the skeleton comprising a first arc-shaped elastic skeleton piece and a second arc-shaped elastic skeleton piece, the first arc-shaped elastic skeleton piece and the second arc-shaped elastic skeleton piece are arranged opposite to each other and the centers of the two circles coincide, there is a gap between the ends of the first arc-shaped elastic skeleton piece and the second arc-shaped elastic skeleton piece, the coil is wound on the outer side walls of the first arc-shaped elastic skeleton piece and the second arc-shaped elastic skeleton piece and plays a shaping role for the first arc-shaped elastic skeleton piece and the second arc-shaped elastic skeleton piece, one end of the coil is welded to the first arc-shaped elastic skeleton piece to form a first welding portion, and the other end of the coil is welded to the second arc-shaped elastic skeleton piece to form a second welding portion.

[0005] The beneficial effects of the utility model are as follows: the utility model provides a shockproof voice coil, which forms a skeleton by forming a separated first arc-shaped elastic skeleton piece and a second arc-shaped elastic skeleton piece, winding the coil on the first arc-shaped elastic skeleton piece and the second arc-shaped elastic skeleton piece, and respectively welding the two ends of the coil on the first arc-shaped elastic skeleton piece and the second arc-shaped elastic skeleton piece, and the skeleton can be assembled on a bracket of a vibrator to position the skeleton, and the positive pole and the negative pole of the vibrator are respectively welded to the first welding part and the second welding part. When the vibrator is working, the magnetic cylinder magnet and the voice coil are integrated, the voice coil does not vibrate, and the whole combination produces a vibration effect, and there is no need to weld leads at both ends of the coil, so as to avoid the problem of voice coil breakage, thereby improving the working reliability of the voice coil, and directly welding the two ends of the coil to the skeleton without using cotton thread, so as to have better productivity and improve production efficiency.

[0011] The utility model provides a shockproof voice coil, comprising a skeleton 1 and a coil 2. The skeleton 1 comprises a first arc-shaped elastic skeleton piece 10 and a second arc-shaped elastic skeleton piece 11. The first arc-shaped elastic skeleton piece 10 and the second arc-shaped elastic skeleton piece 11 are arranged opposite to each other and their centers coincide with each other. There is a gap between the ends of the first arc-shaped elastic skeleton piece 10 and the second arc-shaped elastic skeleton piece 11. The coil 2 is wound on the outer side walls of the first arc-shaped elastic skeleton piece 10 and the second arc-shaped elastic skeleton piece 11 and plays a shaping role on the first arc-shaped elastic skeleton piece 10 and the second arc-shaped elastic skeleton piece 11. One end of the coil 2 is welded on the first arc-shaped elastic skeleton piece 10 to form a first welding portion 12, and the other end of the coil 2 is welded on the second arc-shaped elastic skeleton piece 11 to form a second welding portion 13.
