Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] Such as Figure 1 to Figure 3 As shown, it is a speaker provided by the embodiment of the present invention. The speaker includes a basin frame 10, a vibration system 20 fixed in the basin frame 10 and a magnetic circuit system 30. The vibration system 20 includes an upper sound film fixed in the basin frame 10. 21. The voice coil 22 connected to one side of the upper sound film 21 and driving the upper sound film 21 to vibrate, and the circuit board 25 connected to the end of the voice coil 22 away from the upper sound film 21. The voice coil 22 has a voice coil lead wire 221, and the circuit board 25 includes pads 254 electrically connected to voice coil leads 221 . The vibration system 20 also includes two lower diaphragms 23 corresponding to the upper diaphragm 21 and a dome 26 arranged between the upper diaphragm 21 and the voice coil 22 . ...

Abstract

The invention provides a loudspeaker. The loudspeaker comprises a basin stand, a vibration system fixed on the basin stand and a magnetic circuit system. The vibration system comprises an upper voicediaphragm fixed on the basin stand, a voice coil connected to one side of the upper voice diaphragm and driving the upper voice diaphragm to vibrate, and a circuit board connected to one end, far awayfrom the upper voice diaphragm, of the voice coil; the voice coil is provided with a voice coil lead; the circuit board comprises a bonding pad electrically connected with the voice coil lead; the vibration system further comprises a support, the support comprises a main body part attached to the voice coil and a bending part which bends and extends towards the circuit board from the side, away from the upper voice diaphragm, of the main body part, the bending part is fixed to the circuit board in an overlapped mode, the main body part is provided with receding holes corresponding to the voice coil leads, and the voice coil leads extend out through the receding holes and are electrically connected with the bonding pads. According to the invention, the voice coil is provided with the support, and the support avoids the voice coil lead, so that the swing of the voice coil is controlled, and the avoidance of the support does not affect the assembly of the voice coil and does not damage the voice coil lead.

Description

【Technical field】 [0001] The invention belongs to the field of electroacoustic technology, and in particular relates to a loudspeaker. 【Background technique】 [0002] With the rapid development of science and technology, audio equipment is also developing rapidly. People have higher and higher functional requirements for audio equipment. For speakers, more and more people put forward higher requirements for their audio performance. In the related art, the voice coil tends to swing unnecessarily during the operation of the loudspeaker, and the fixing of the lead wire of the voice coil will also be affected. 【Content of invention】 [0003] The purpose of the present invention is to provide a loudspeaker, aiming to solve the problem of voice coil swing in the related art. [0004] The technical scheme of the present invention is as follows: a loudspeaker, which includes a basin frame, a vibration system fixed on the basin frame and a magnetic circuit system, the vibration sy...
