Problems solved by technology

[0002] In the previous technology such as the traditional closed speaker, the vibration of the diaphragm will cause the sound wave to bounce in the speaker, and the pressure caused by the rebound of the sound wave will cause the vibration of the diaphragm to be disturbed, suppress the amplitude of the diaphragm, and make the speaker perform at low frequencies. poor
[0003] In order to improve the shortcomings of the traditional closed speakers, the active loudspeaker with reflexport has an inverted tube, which releases the pressure caused by the sound rebound to the outside of the speaker, so as to eliminate the shortcomings of the traditional closed speakers. The phase tube releases the pressure to the outside of the speaker, and the air in the speaker will leak out of the phase tube, which reduces the sound resistance inside the speaker and distorts the sound of the speaker

Embodiment Construction

[0025] figure 1 is a schematic diagram of the loudspeaker structure of the embodiment of the present invention. figure 2 yes figure 1 A top view of the loudspeaker structure. Please refer to figure 1 and figure 2 , the loudspeaker structure 100 of this embodiment includes a sound box 130 , a passive diaphragm 110 , an active diaphragm 120 and a magnet 140 . The passive diaphragm 110 is disposed on the speaker 130 . The active diaphragm 120 is disposed on the speaker 130 and has a voice coil 123 surrounding the magnet 140 . The active diaphragm 120 is adapted to vibrate by receiving signals from the voice coil 123 . The passive diaphragm 110 and the active diaphragm 120 correspond to the co-resonant space 150 of the sound box.

[0026] In this embodiment, when the active diaphragm 120 vibrates, the passive diaphragm 110 will vibrate together. When the active diaphragm 120 vibrates outward, the air pressure inside the sound box 130 becomes smaller, so that the passive ...

Abstract

The invention provides a loudspeaker structure. The loudspeaker structure comprises a sound box, a passive diaphragm and an active diaphragm. The passive diaphragm is disposed on the sound box. The active diaphragm is configured on the sound box and is suitable for receiving the signal and vibrating to drive the passive diaphragm to vibrate, and when the active diaphragm vibrates towards the inside of the sound box, the passive diaphragm vibrates towards the outside of the sound box.

Description

technical field [0001] The invention relates to an acoustic device, in particular to a loudspeaker structure. Background technique [0002] In the previous technology such as the traditional closed speaker, the vibration of the diaphragm will cause the sound wave to bounce in the speaker, and the pressure caused by the rebound of the sound wave will cause the vibration of the diaphragm to be disturbed, suppress the amplitude of the diaphragm, and make the speaker perform at low frequencies. poor. [0003] In order to improve the shortcomings of the traditional closed speakers, the active loudspeaker with reflexport has an inverted tube, which releases the pressure caused by the sound rebound to the outside of the speaker, so as to eliminate the shortcomings of the traditional closed speakers. The phase tube releases the pressure to the outside of the speaker, and the air in the speaker will leak from the inverter tube, which reduces the sound resistance inside the speaker a...
