Embodiment Construction

[0016] In order to make the above and other objectives, features and advantages of the present invention more obvious and understandable, the following is a detailed description of the preferred embodiments of the present invention in conjunction with the accompanying drawings:

[0017] The speaker of the present invention such as figure 2 , image 3 , Figure 4 , Consists of tweeter 1, midrange speaker 2, woofer 3, infrared receiver 4, LED display 5, audio input (left) 911, audio input (right) 912, stereo audio input 913, USB input 914, audio output (Left) 921, audio output (right) 922, video output 923, control module 924, processor 925, power amplifier 926. Tweeter 1, midrange speaker 2, and woofer 3 are sounding units, and the input audio signal is processed by the circuit integration block 6 and then sent to them for sound. The infrared receiver 4 is an infrared receiving device, which receives the control signal emitted by the speaker remote controller and cooperates with...

Abstract

The invention provides a loudspeaker box which comprises a high pitch loudspeaker, a middle pitch loudspeaker, a low pitch loudspeaker, an infrared receiver, an LED (Light Emitting Diode) display screen and a circuit integration block, wherein the infrared receiver is used for receiving a control signal; the LED display screen is electrically connected to the infrared receiver; the circuit integration block comprises one group of audio input, a stereo audio input, a USB (Universal Serial Bus) input, one group of audio output, a video output, a processor, a power amplifier and a control module; the power amplifier is electrically connected to the high pitch loudspeaker, the middle pitch loudspeaker, the low pitch loudspeaker, the infrared receiver and the LED display screen; the USB input is connected to the processor; and the audio output is used for outputting a signal which is input from the audio input, the stereo audio input, the USB input and the processor and is processed by the power amplifier. Therefore, the complex wiring when the traditional video and the traditional audio are played is avoided, and the loudspeaker box is convenient and quick to connect.

Description

Technical field [0001] The invention relates to a sound box, in particular to a sound box having both video and audio functions. Background technique [0002] Existing speakers such as figure 1 , It is generally composed of tweeter 1, midrange unit 2, and bass unit 3. This kind of speakers can indeed significantly improve the poor sound quality of TV speakers, but its function is single and can only play audio signals. When it is necessary to play audio and video files on mobile media such as mobile hard disks and U disks, There is nothing I can do. To this end, the present invention provides a new sound box structure, which not only can produce good sound quality, but also overcomes the shortcomings of the single function of the existing home sound box. It can input DVD, TV, MP3, MP4, etc. through multiple interfaces. The audio signal of iphone, ipad, music phone, etc. and the audio, video, graphic signal on mobile media such as computer, mobile hard disk, U disk, etc., and th...
