Description

Ceiling type ceiling sound box system

Technical Field

The utility model relates to an audio amplifier field, concretely relates to ceiling type smallpox audio amplifier system.

Background

With the popularization of home theaters, ceiling-mounted ceiling-type sound boxes gradually enter a home music system, are widely applied to background music in hotels, restaurants, schools, office buildings, business places, panoramic sounds of cinemas and the like, are mainly mounted on ceilings and are very suitable for being used for playing background music in small-area spaces such as study rooms, bedrooms, business background music and the like. In the aspect of the appearance of the loudspeaker box, the front baffle plate of a common ceiling loudspeaker box is generally circular, and the number of the loudspeaker box units used is relatively small, and the loudspeaker box units are generally 2 units or less, so that the volume is greatly reduced, the ceiling can be decorated by using the ceiling loudspeaker box, the ceiling can be utilized to play a sound insulation effect, and the problems of sound diffraction and box body vibration can be solved even.

As shown in fig. 1, a ceiling-type sound box system in the prior art generally includes independent components such as a tuner, an effector, a volume controller, a frequency divider, a plurality of power amplifiers connected to the frequency divider, and a small sound box connected to the power amplifiers, which need to be installed on a ceiling of a building, respectively, so that the installation operation of the ceiling-type sound box system becomes quite cumbersome.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a ceiling type smallpox audio amplifier system to solve the complicated technical problem that leads to installing loaded down with trivial details of ceiling type smallpox audio amplifier system structure of prior art.

The utility model discloses a solve the technical scheme that its technical problem adopted and be:

the utility model provides a ceiling type smallpox audio amplifier system, its include sound source equipment and with the audio amplifier array that sound source equipment is connected, the audio amplifier array includes a plurality of main speakers and a plurality of follow audio amplifier, and each main speaker corresponds and is connected with a plurality of follow audio amplifiers, be provided with a DSP audio frequency processing circuit board in the main speaker, set up a DSP chip on the DSP audio frequency processing circuit board, tuner, effector, frequency divider and power amplifier have been integrated in the DSP chip.

In the embodiment of the present invention, the sound source device is a notebook computer or a tablet computer.

In the embodiment of the utility model provides an in, last WIFi module, bluetooth module, USB interface module and a plurality of sound channel output module of still having set up of DSP audio frequency processing circuit board.

In the embodiment of the utility model, the sound source equipment passes through USB interface module with main audio amplifier connects.

In the embodiment of the utility model, the main speaker passes through a plurality of sound channel output module with a plurality of from the audio amplifier is connected.

Compared with the prior art, adopt the technical scheme of the utility model, will integrate DSP chip into ceiling type smallpox audio amplifier system, integrated tuner, effector, frequency divider and power amplifier in the DSP chip the wire rod cost has been saved and the wire rod interference has been prevented, has simplified ceiling type smallpox audio amplifier system's structure, has reduced ceiling type smallpox audio amplifier system's the installation degree of difficulty.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in fig. 2, in the embodiment of the present invention, a ceiling type ceiling loudspeaker system is provided, which includes a sound source device 1 and a loudspeaker array (not labeled) connected to the sound source device. The loudspeaker array comprises a plurality of master loudspeakers 2 and a plurality of slave loudspeakers 3. Each main sound box is correspondingly connected with a plurality of auxiliary sound boxes 3. The sound source device 1 may be a notebook computer or a tablet computer, or may be a mobile phone or other mobile storage devices.

As shown in fig. 3, a DSP audio processing circuit board 4 is disposed in the main speaker 2, and a DSP chip 5, a WIFi module 6, a bluetooth module 7, a USB interface module 8, and a plurality of sound channel output modules 9 are disposed on the DSP audio processing circuit board 4. And a tuner, an effector, a frequency divider and a power amplifier are integrated in the DSP chip 5. Because inside tuner, effector, frequency divider and the power amplifier of having integrateed of DSP chip 5 to need not to adopt independent discrete device's tuner, effector, frequency divider and power amplifier, thereby reduced ceiling type smallpox audio amplifier system's structural complexity has simplified ceiling type smallpox audio amplifier system's installation.

The sound source device 1 can be connected with the main sound box 2 through the USB interface module 8. Further, the main speaker 2 may also perform wireless communication connection with the sound source device in a WIFi connection manner or a bluetooth connection manner through the WIFi module 6 or the bluetooth module 7. The master loudspeaker box 2 is connected with the slave loudspeaker boxes 3 through the sound channel output modules 9.

To sum up, adopt the technical scheme of the utility model, will integrate DSP chip into ceiling type smallpox audio amplifier system, integrated tuner, effector, frequency divider and power amplifier in the DSP chip the wire rod cost has been saved and wire rod interference has been prevented, has simplified ceiling type smallpox audio amplifier system's structure, has reduced ceiling type smallpox audio amplifier system's the installation degree of difficulty.
