Abstract

The invention discloses a novel sound box. The novel sound box comprises a box body. A power supply driving circuit, an audio playing circuit, a control circuit and an LED lamp circuit are arranged in the box body. The power supply driving circuit comprises an electromagnetic filtering circuit. The electromagnetic filtering circuit is successively connected with a bridge rectifying circuit, an inverting circuit, an output rectifying circuit and an output filtering circuit. A high frequency voltage transformation circuit is connected with a sampling circuit. The output filtering circuit is connected with the LED lamp circuit. The audio playing circuit comprises an audio power amplifying circuit connected with the output filtering circuit. The audio power amplifying circuit is connected with a loudspeaking circuit. The control circuit comprises a controller. The controller is connected with the bridge rectifying circuit controlled through a feedback signal of the sampling circuit, the LED lamp circuit and an audio power amplifier. According to the invention, the damage of the sound box in an operating process is reduced effectively, and the service life of the controlled through a feedback signal of the sampling circuit box is prolonged.

Description

[technical field] [0001] The invention relates to a novel sound box. [Background technique] [0002] Due to the large demand for electricity nowadays, it is easy to cause the current and voltage output by the grid to be unstable, which makes the speaker prone to noise under the action of an unstable power supply, and works in an environment of unstable current and voltage for a long time. At the same time, the existing speakers do not There is a good cooling device, which makes the speaker components very easy to damage and greatly reduces the life of the speaker. [Content of the invention] [0003] The present invention overcomes the disadvantages of the above-mentioned technologies and provides a new type of sound box. A drive circuit and a cooling circuit that can prevent lightning strikes and eliminate electromagnetic interference to stabilize the current and voltage are installed in the sound box to reduce damage to the sound box during operation and prolong its servi...
