Description
[technical field]
The utility model relates to the equipment of the karaoke that is applied to family, particularly a kind of television karaoke device with USB interface.
[background technology]
Present Caraok device, normally rely on video disc player or Karaoke specialized equipment to come played songs and picture, and sing by microphone, video disc player need be bought a lot of Karaoke song dish, one, the two first songs that people have to like for oneself are bought whole song dish, and in today that new song, good song emerge in an endless stream, people need buy more song dish, uneconomical, and the frequent dish that changes all has very big influence to life-span of disc player and video disc; Simultaneously, along with the development of computer and network technologies with popularize, increasing people more gets used to the use of network multimedia resource, the equipment that has USB interface and other new types of data interfaces is also used by increasing people, people can find the song of oneself liking in a large number on the internet, but owing to device-restrictive can't also be to allow the incomparable regret of people with its download and performance.Therefore, how can provide a kind of and can download storage from the Internet, and the Caraok device that can upgrade in time, a difficult problem on the industry become.
[utility model content]
For addressing the above problem, fundamental purpose of the present utility model is to provide a kind of can download storage easily from the Internet, can upgrade in time and the television karaoke device of economical and practical band USB interface.
For achieving the above object, a kind of television karaoke device of the technical scheme of this creation with USB interface, comprise the audio frequency and video processing module, be connected with the audio frequency and video processing module, TV video processing module with the vision signal that is used for handling the output of audio frequency and video processing module, be connected with the audio frequency and video processing module, audio mix amplification module with the accompaniment signal that is used for handling the output of audio frequency and video processing module, the TV audio processing modules that connects described audio mix amplification module, receive microphone signal and it is carried out the voice reverberation processing module that reverberation is handled, it is characterized in that: described audio frequency and video processing module includes the GPIO interface, is connected with the USB driver module with this GPIO interface.
Compared to prior art, a kind of television karaoke device with USB interface of the utility model can be downloaded storage easily from the Internet, and can upgrade in time, and is economical and practical.
[description of drawings]
Fig. 1 is a functional-block diagram of the present utility model.
[embodiment]
Please refer to shown in Figure 1, a kind of television karaoke device of the utility model with USB interface, comprise the audio frequency and video processing module, be connected with the audio frequency and video processing module, TV video processing module with the vision signal that is used for handling the output of audio frequency and video processing module, be connected with the audio frequency and video processing module, with the audio mix amplification module of the accompaniment signal that is used for handling the output of audio frequency and video processing module, the TV audio processing modules that connects described audio mix amplification module, receive microphone signal and it is carried out voice reverberation processing module and power module and the infrared ray receiver module that reverberation is handled.
The audio frequency and video processing module possesses MPEG-1 is arranged, all functions of MPEG-2, MPEG-4 decoding, and its built-in 32-BIT CPU can handle special instruction to accelerate the processing speed of audio frequency and video; Described audio frequency and video processing module includes the GPIO interface, directly be connected by the GPIO interface with the USB driver module, draw two USB interface of supporting High Speed USB2.0, utilize these two USB interface of supporting High SpeedUSB2.0, can expand a plurality of USB interface.In the present embodiment, adopt following expansion: one of them is directly used in and connects the USB external device, and described USB external equipment can be external units such as PC; Another expands a plurality of interfaces by usb hub, connects the memory device of various band USB interface, and specifically expanding quantity can be according to actual needs.Described audio frequency and video processing module also includes compatible various form coding, with the DAB output interface that connects the audio mix amplification module, adapt to high definition output, with the video coding output interface that connects the TV video processing module and the infrared interface that receives the various operational orders that telepilot sends.
The original corresponding module of described infrared receiving module and televisor is shared, switch to the Karaoke state after, the various command of sending from the TV remote controller respective keys just can enter from the infrared interface of digital audio/video processing module, to produce various control commands.Produce switch command simultaneously, its power module of may command so that when Kara OK function is closed, cuts off its line related, more economize on electricity.
During application, the USB memory device, stores the proprietary format song files of downloading from the internet, by the televisor USB interface, the USB interface that is the usb hub expansion sends song data to the audio frequency and video processing module, the audio frequency and video processing module is decoded to the song files in the USB memory device, and the video signal transmission of decoding back output is given the TV video processing module; The sound signal of output, i.e. accompaniment part is imported the audio mix amplification module after treatment; People's acoustical signal that the voice part is then imported by MIC is transferred to voice reverberation processing module and carries out the reverberation processing, and the signal after the processing and untreated straight-through people's acoustical signal are mixed input audio mix amplification module; Like this, the accompaniment signal, the people's acoustical signal after reverberation is handled and straight-through people's acoustical signal three mix input audio mix amplification module and carry out hybrid processing; After the accompaniment signal that the audio mix amplification module will be imported, reverb signal and the through connect signal mixing amplification, output signal is the Karaoke sound signal that needs, and this signal is connected to can carry out on the related audio treatment circuit of televisor after the power amplification by the output of TV loudspeaker.
Storage file comprises video background, lyrics subtitle file, accompaniment music and primary sound three aspect contents for adopting special-purpose form on the external USB memory device.These content stores can be carried out down loading updating timely by special website on the storer of hard disk, USB flash disk.
Most preferred embodiment described above only is that the utility model is set forth and illustrated, but is not limited to disclosed any concrete form, and it is possible carrying out many modifications and variations.
