The working principle of the utility model are as follows:
When audio power is exported to active speaker 3, the loudspeaker unit vibrating diaphragm of active speaker 3 generates vibration, complete
It is converted at electroacoustic and generates sound.The basic, normal, high sound that 3 vibrating diaphragm front of active speaker generates, is directly radiated listening volume, together
When in low frequency, vibrating diaphragm amplitude is very big, and vibrating diaphragm will compress the sky in ultra-thin cabinet 1 to when ultra-thin 1 internal vibration of cabinet
Gas makes the atmospheric pressure in ultra-thin cabinet 1 be greater than ambient air pressure, this pressure difference of generation will drive two passively to raise
The vibrating diaphragm of sound device 4 is vibrated to the direction of ultra-thin 1 outside of cabinet simultaneously.When 3 vibrating diaphragm of active speaker is vibrated to outside ultra-thin cabinet 1
When, the drop of pressure in ultra-thin cabinet 1 makes the pressure in ultra-thin cabinet 1 lower than ambient air pressure, drives again to generate pressure difference
Dynamic two 4 vibrating diaphragms of passive loudspeaker are simultaneously to ultra-thin 1 internal vibration of cabinet.Bass information stream is formed in cabinet 1 ultra-thin in this way
Spring effect, enhances bass, makes the ultra-thin cabinet 1 of speaker that can obtain the bass effect of big sound box under small volume
Fruit, while bass boost, box volume is significantly narrowed down within 0.7 liter.Meanwhile table is provided on ultra-thin cabinet 1
Face mounting device 2 realizes Ceiling loudspeaker housing and installs on the surface of ceiling in the case where not punching.Simultaneously in ultra-thin cabinet 1
On be also provided with LED light 8, LED light 8 generates light after being powered, realize headlamp effect.
The ceiling speaker of the utility model is set to independent closed cavity using active speaker 3 and passive loudspeaker 4
System design, tank-volumes are greatly reduced；Basic, normal, high sound can realize sound-reducing very well simultaneously.It is also provided with table
Face mounting device 2 realizes in the case where ceiling not wide-bore hole, installs on the surface of ceiling, greatly reduces peace
Complexity and difficulty and installation cost are filled, so that people is being punched and can be voluntarily being installed in ceiling without specific purpose tool, simultaneously
Use scope is expanded, the beauty of decoration is increased.The utility model is also provided with LED light 8, and simple function product is made to become sound
Case illuminates dual function product.
