Abstract

The invention discloses a loudspeaker with a breathable elastic wave module. The loudspeaker comprises a vibration assembly, a magnetic loop assembly, a loudspeaker base and a breathable elastic wavemodule. The vibration assembly comprises a diaphragm and a voice coil. The voice coil is connected to the bottom of the vibrating diaphragm; the magnetic loop assembly comprises an air guide base anda magnet piece; the magnet piece is arranged on the air guide base; the voice coil is arranged outside the magnet piece in a floating mode; the magnet piece is provided with a through hole; the loudspeaker base is arranged on the vibration assembly and the magnetic loop assembly; the breathable elastic wave module comprises a hollow cylinder and a first elastic piece; the hollow cylinder is arranged in the through hole and communicated with the air guide base; and the first elastic piece is arranged in the hollow position of the hollow cylinder and connected to the bottom of the vibrating diaphragm. According to the loudspeaker with the breathable elastic wave module, polarization distortion of the voice coil can be relieved through the breathable elastic wave module under the condition that the height of the loudspeaker is not increased, and the output volume of the loudspeaker is increased.

Description

technical field [0001] The invention relates to a loudspeaker, more particularly to a loudspeaker with a ventilated elastic wave module.

Especially at low frequencies, once the voltage is increased, the polarization distortion of the voice coil is more likely to occur, and even cause the voice coil to hit the magnetic return component to produce abnormal sound. [0003] Traditionally, in order to solve the polarization distortion of the voice coil at large amplitudes, it is usually necessary to use elastic waves as dampers to absorb the offset of the voice coil at large amplitudes, but the micro-speaker is small in size...

AI Technical Summary

Problems solved by technology

[0002] Due to the small size of the micro-speaker, the volume is limited. Although the volume can be increased by increasing the input voltage of the speaker, the amplitude of the voice coil will be increased, and it is difficult to maintain the stable vibration of the voice coil in the axial direction, resulting in sound distortion.

Especially at low frequencies, once the voltage is increased, the polarization distortion of the voice coil is more likely to occur, and even cause the voice coil to hit the magnetic return component to produce abnormal sound

[0003] Traditionally, in order to solve the polarization distortion of the voice coil at large amplitudes, it is usually necessary to use elastic waves as dampers to absorb the offset of the voice coil at large amplitudes, but the micro-speaker is small in size and uses the traditional elastic wave structure, However, it will increase the height of the micro-speaker, so it is not suitable for use in products such as thin notebook computers or tablet computers

In addition, the traditional elastic wave structure does not adopt a modular design. When the height and space of the micro-speaker are limited, it is not easy to assemble and connect the elastic wave with other parts of the speaker, and the assembly work is more complicated.
