Obtain preferable audio after radiator, but simultaneously because low frequency radiation device adds effect of vibration power caused by audio amplifier, and
Furred ceiling audio amplifier is connected on the furred ceiling in house, therefore during the motion of furred ceiling audio amplifier, the active force of vibration has been delivered into furred ceiling
On, so as to cause furred ceiling to send the noise of abnormal sound during the work of furred ceiling audio amplifier, the sound sent to furred ceiling audio amplifier generates interference.
The content of the invention
The purpose of this utility model is to provide a kind of furred ceiling audio amplifier, and the utility model can remove because vibration makes caused by furred ceiling
Noise.
The technical scheme for solving above-mentioned technical problem is as follows：
Furred ceiling audio amplifier, including fore shell, bonnet, loudspeaker, fore shell are provided with receiving cavity, and fore shell is provided with through hole, and loudspeaker are put
In in the receiving cavity on fore shell, after one end of loudspeaker is fitted in the through hole on fore shell, loudspeaker are tight with fore shell by fastener
It is solidified as a whole, fore shell is provided with the first low frequency radiation device, and bonnet is arranged on the oral area of the receiving cavity on fore shell so as to by loudspeaker
Be encapsulated in the airtight cavity that fore shell and bonnet are formed, fore shell or after cover the installation portion that is additionally provided with and is attached with furred ceiling,
Covered after described provided with pilot hole, be fitted with being used to offset effect of vibration power caused by the first low frequency radiation device at the pilot hole
The second low frequency radiation device, the position of the second low frequency radiation device and the first described low frequency radiation device is not staggered.
The second low frequency radiation device and the position of the first described low frequency radiation device are mutually corresponding.
The installation portion includes the endless member being arranged on fore shell, and vibration damping of the part configuration in endless member
Part, the both ends of damping means are exposed to the outside of endless member respectively.
The side face of the endless member is provided with breach, and the damping means are entered in endless member by the breach.
The damping means include sleeve pipe, and the both ends of the sleeve pipe are provided with radially projecting annular projection portion.
The installation portion also includes the supporting plate of support endless member, and the supporting plate is arranged on fore shell.
Such scheme is employed, i.e., is fitted with being used to offset to vibrate caused by the first low frequency radiation device at the pilot hole making
The second low frequency radiation device firmly, the position of the second low frequency radiation device and the first described low frequency radiation device are not staggered.Work as sound
When case works, the be squeezed active force of air of the first low frequency radiation device and the second low frequency radiation device produces vibration respectively, but the
It is opposite in terms of the vibration of one low frequency radiation device and the second low frequency radiation device, therefore, active force caused by both is a pair
Reverse active force, so, after setting up the second low frequency radiation device, it can offset caused by the work of the first low frequency radiation device
Effect of vibration power.
