Abstract

The utility model discloses a digital-sound player combining a digital function and a power amplifier (preceding-stage control function and karaoke) function. The player comprises a power-amplifier device, a decoding device, a sound box and a wireless remote controller, wherein the decoding device capable of decoding data of a USB removable disk or MP3 and WMA of a SD card is arranged on the power-amplifier device; the sound box is arranged at the outer part of the power-amplifier device and connected with the power-amplifier device; and the wireless remote controller performs the integrated control over the power-amplifier device and the decoding device. The wireless remote controller has the functions of random song selection, volume, tone, MP3 play and the like. The utility model provides the digital-sound player which has the advantages of convenient operation, and structural and functional integration, and can be used for the karaoke.

Description

A kind of digital sound player

Technical field

The utility model relates to the player field, the digital sound player that particularly a kind of digital function and power amplifier (prime control function and Karaoke) function unites two into one.

Background technology

At present, player on the market mainly is audio amplifier that device is externally connected to by power amplification device, outside power amplifier and the Digiplex that can wirelessly operate power amplification device, also have with the power amplification device wired connection and can read the USB displacement disc or the SD card in the computer of data.During use, at first read the data of USB displacement disc or SD card by computer after, again the data in USB displacement disc or the SD card are sent on the power amplification device by computer, last with Digiplex control power amplification device the data after transmitting are play again.Because the player of this structure should be decoded to the data in USB displacement disc or the SD card with computer for the process of operation, with Digiplex power amplification device is play again, thus very loaded down with trivial details in the operation, be not easy to popular the use; Again because the decoding of USB displacement disc or SD card relies on computer to finish, so also very complicated on the structure.

The utility model content

In order to address the above problem, it is a kind of easy to operate that the purpose of this utility model is to provide, and 26S Proteasome Structure and Function is integrated, and can realize the effect that bass compensation, good tone color, range widen, and can be used for the digital sound player of Kara OK function in addition.

For achieving the above object, the technical scheme that the utility model adopted is:

A kind of digital sound player, it is characterized in that this player comprises power amplification device, is provided with the decoding device that can decode to the data of the MP3 of USB displacement disc or SD card and WMA on power amplification device, and be arranged at the audio amplifier that power amplification device is outside and is connected with power amplification device, the Digiplex that can unite two into one and control power amplification device and decoding device in addition.

More excellent, described decoding device comprises the shell that is arranged on the power amplification device, the USB slot that on shell, is provided with, the SD card slot that on shell, is provided with, portion is provided with the wiring board that is connected with SD card slot with the USB slot and can reads MP3 and WMA data on the USB displacement disc in the enclosure, on shell, be provided with and show the display screen that reads USB displacement disc or SD card state, and be provided with on the shell can be to USB displacement disc or SD card on the keyboard operated of MP3 and WMA data, this decoding device has been realized integrated number and the integrated control of function, can be on Digiplex each function (comprising the control of song) and the subsonic volume of logarithmic code, the global function of Karaoke, the DSP sound field effect, quality of balance or the like function is controlled.

More excellent is that the bottom is provided with the bass compensation loudspeaker that mates with left and right sides audio amplifier in the described power amplification device.

More excellent, described power amplification device is provided with the microphone jack that can realize Kara OK function.

After adopting technique scheme, because decoding device is arranged on the power amplification device, mainly be to adopt same CPU to control, and Digiplex can be controlled power amplification device and decoding device, during use, only need just can realize above-mentioned two devices are controlled, so easy to operate with a Digiplex; Because decoding device and power amplification device are one,, realized the incorporate effect of structure again so relative prior art is simple in structure many; Also, also can realize the effect that bass compensation, good tone color, range widen because the power amplification device bottom is provided with low sound column.

Embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail.

As Fig. 1 and shown in Figure 6, a kind of digital sound player, this player comprises power amplification device 1, be provided with the decoding device 2 that can decode to the data of the MP3 of USB displacement disc or SD card and WMA on power amplification device 1, and be arranged at the audio amplifier that power amplification device 1 is outside and is connected with power amplification device 1, the Digiplex that can unite two into one and control power amplification device 1 and decoding device 2 in addition.Described decoding device 2 comprises the shell 21 that is arranged on the power amplification device 1, the USB slot 22 that on shell 21, is provided with, the SD card slot 23 that on shell 21, is provided with, be provided with the wiring board 24 that is connected with SD card slot 23 with USB slot 22 and can reads MP3 and WMA data on the USB displacement disc in shell 21 inside, on shell 21, be provided with and show the display screen 25 that reads USB displacement disc or SD card state, and be provided with on the shell 21 can be to USB displacement disc or SD card on the keyboard 26 operated of MP3 and WMA data, power amplification device 1 bottom is provided with to match with audio amplifier realizes the low sound column 4 of bass compensation, and power amplification device 1 is provided with the microphone jack 3 that can realize Kara OK function.

During use, only need just can realize above-mentioned two devices are controlled with a Digiplex, thus easy to operate, realized the effect that good tone color, range widen.

Above-described only is the preferred implementation of the utility model digital sound player; should be understood that; for the person of ordinary skill of the art; under the prerequisite that does not break away from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
