Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of power amplifiers, in particular to an embedded four-channel power amplifier. Background Technique
[0002] The power amplifier, namely the power amplifier, is a basic and important device in the audio system, commonly known as the "amplifier". Its main function is to amplify the weak electrical signal from the signal source (such as the mixer in a professional audio system) to drive the speaker to emit sound. The main role of the power amplifier is to amplify the weak signal of the sound source or the preamplifier, and then drive the speaker to sound. In the audio system, the role of the power amplifier is crucial, which determines whether the audio system can provide high-quality and high-definition audio amplification.
[0003] The angle radiated to the front when the audio is played depends on various factors, such as the design of the speaker, the number of drivers, the size of the speaker, and the materials used, etc. Generally speaking, the radiation angle of the speaker can range from 0 degrees to 180 degrees. At present, for the hanging speakers or floor-standing speakers in indoor or basketball court and other places, the traditional ones are single two-channel speakers. Since the angle of most single speakers pointing forward is mostly 0-180 degrees, the sound intensity in the range behind the speaker will be much lower. Especially for the hanging speakers, the sound intensity behind the speaker is significantly weakened and cannot cover the entire venue range. Therefore, when used in places with a high frequency of temporary events and other mobile occasions, it is necessary to increase the number of speakers to achieve the effect of covering the entire venue sound. This not only increases the cost, but also is time-consuming and laborious for moving and handling, and also takes up space.
[0004] Therefore, in view of the above problems, an embedded four-channel power amplifier is needed. Content of the Utility Model
[0005] The purpose of the utility model is to provide an embedded four-channel power amplifier. The utility model rotates the second power amplifier housing through a damping rotating shaft on the first power amplifier housing. By rotating the angles of the first power amplifier housing and the second power amplifier housing, the range to be covered can be adjusted arbitrarily. For example, the traditional one can only cover 0-180 degrees. Through the first speaker, the second speaker, the third speaker and the fourth speaker of this device, the audio area to be covered within the range of 0-360 degrees can be quickly covered.
[0006] In the venue that needs to be hung, it can be directly connected by the connecting rod installed on the top of the ceiling and the threaded hole on the top of the second power amplifier housing of this application. One connecting rod can connect one speaker that covers the entire venue, without the disadvantage that multiple speakers need to be installed traditionally to cover the entire venue. The utility model is simple and convenient to operate and has strong practicability.
[0007] The present utility model is implemented as follows:
[0008] An embedded four-channel power amplifier includes a bottom plate. A first power amplifier housing is fixedly provided on the bottom plate. A first loudspeaker and a second loudspeaker are spacedly provided on the first power amplifier housing. A rotating shaft is provided at the top of the first power amplifier housing. A second power amplifier housing is rotatably connected through the rotating shaft. A third loudspeaker and a fourth loudspeaker are spacedly provided on the second power amplifier housing.
[0009] On both sides of the back end of the first power amplifier housing, inclined struts are provided. Bottom pads are fixedly provided at the bottom ends of the two inclined struts. When the entire device is placed on the ground through the bottom pads, the inclined struts can stably support the entire device.
[0010] Furthermore, the first loudspeaker and the second loudspeaker are both embedded in the first power amplifier housing. The third loudspeaker and the fourth loudspeaker are both embedded in the second power amplifier housing. The rotating shaft adopts a damping rotating shaft. A threaded connection hole is provided at the top of the second power amplifier housing. The threaded connection hole facilitates connection to the top of the venue through a threaded connecting rod to threadedly fix and connect the entire device to be suspended in the venue.
[0011] Furthermore, a control processing unit is fixedly provided in the first power amplifier housing. An information transmission unit is connected to the control processing unit. The control processing unit is also connected to a power amplification unit. The first loudspeaker, the second loudspeaker, the third loudspeaker, and the fourth loudspeaker are respectively connected to the output end of the power amplification unit. The power amplification unit adopts a DP-4065 type four-channel power amplifier.
[0012] Compared with the prior art, the present utility model has a second power amplifier housing rotatably connected to the first power amplifier housing through a damping rotating shaft. By rotating the angles of the first power amplifier housing and the second power amplifier housing, the coverage range to be covered can be adjusted arbitrarily. For example, the traditional one can only cover 0 - 180 degrees. Through the first loudspeaker, the second loudspeaker, the third loudspeaker, and the fourth loudspeaker of the present device, the sound field to be covered within the range of 0 - 360 degrees can be quickly covered.
[0013] In the venue where it needs to be hung, it can be directly connected through the connecting rod installed on the top of the ceiling to the threaded hole at the top of the second power amplifier housing of the present application. One connecting rod can connect an audio that covers the entire venue, eliminating the drawback of the traditional method that requires installing multiple audio to cover the entire venue. The present utility model is simple and convenient to operate and has strong practicability. The present utility model has strong practicability. Description of the Drawings
