1. Field of the Invention
The present invention generally relates to a sound box and, more particularly, to a sound box having audio and video functions.
2. Description of the Related Art
A conventional sound box generally includes a tweeter 1, a mid-range speaker 2 and a woofer 3 as shown in
It is therefore the primary objective of the invention to provide a sound box having multiple audio and video interfaces for receiving audio signals from devices such as DVD, TV, MP3, MP4, iphone, ipad or music cell phone, as well as audio, video and image signals from devices such as computer, portable hard drive and flash drive.
Modern liquid crystal TVs are getting popular. However, the liquid crystal TVs do not provide good sound quality, requiring external sound boxes for better sound quality. In light of this problem, the invention provides a sound box which not only produces good sound quality but also provides more functions than the conventional sound box. The sound box of the invention provides multiple input and output interfaces, allowing audio signals of DVD, TV, MP3, MP4, iphone, ipad or music cell phone, as well as audio, video and image signals of computers, portable hard drives or flash drives, to be input in the sound box through the input interfaces. At the same time, the output interfaces of the sound box are connected to external devices to play the audio and video signals. Furthermore, the sound box of the invention has optimized internal circuits with simpler wiring for audio and video playing.
The invention discloses a sound box including a tweeter, a mid-range speaker, a woofer, an infrared receiver, a LED displayer and an integral module. The infrared receiver receives a control signal. The LED displayer is electrically connected to the infrared receiver. The integral module includes a processor, at least one audio input port, a stereo audio input port, an USB input port, a video output port, a power amplifier, at least one audio output port and a control module. The USB input port is electrically connected to the processor. The video output port is electrically connected between the processor and a displayer. The power amplifier has an output port and is electrically connected to the tweeter, mid-range speaker, woofer, infrared receiver and LED displayer. The audio output port sends signals from the audio input port, stereo audio input port, USB input port and processor to the power amplifier for amplification, wherein the power amplifier amplifies the received signals to generate an amplified signal that is sent to the tweeter, mid-range speaker and woofer via the output port thereof. The control module is electrically connected to the power amplifier, wherein audio, video or image signals are received via the audio input port, stereo audio input port and USB input port, and the audio output port and video output port are connected to an external device so as to replay the audio, video or image signals.
The present invention will become more fully understood from the detailed description given hereinafter and the accompanying drawings which are given by way of illustration only, and thus are not limitative of the present invention, and wherein:
In the various figures of the drawings, the same numerals designate the same or similar parts. Furthermore, when the term “first”, “second”, “third”, “fourth”, “inner”, “outer” “top”, “bottom” and similar terms are used hereinafter, it should be understood that these terms refer only to the structure shown in the drawings as it would appear to a person viewing the drawings, and are utilized only to facilitate describing the invention.
Referring to
The integral module 6 consists of the left audio input port 911, right audio input port 912, stereo audio input port 913, USB input port 914, left audio output port 921, right audio output port 922, video output port 923, control module 924, processor 925 and power amplifier 926. Thus, the integral module 6 allows the audio, video and image signals to be input in the sound box through various input interfaces thereof, and allows the processed audio and video signals to be played by external devices connected to the output interfaces thereof.
Referring to
The sound box of the invention not only allows audio signals to be input via the left audio input port 911, right audio input port 912 and stereo audio input port 913, but also allows audio, video and image signals to be input via the USB input port 914. As such, the left audio output port 921, right audio output port 922 and video output port 923 are connected to external devices to replay the audio, video or image signals. In conclusion, the sound box of the invention not only has both audio and video functions, but also allows inputting and outputting of both audio and video signals. Thus, easy usage of the sound box is provided.
Although the invention has been described in detail with reference to its presently preferable embodiment, it will be understood by one of ordinary skill in the art that various modifications can be made without departing from the spirit and the scope of the invention, as set forth in the appended claims.
