Abstract: The invention relates to a data processing module of a digital audio processing device, a digital audio processing controller module of a portable device and a control system. Using the data processing module of the digital audio processing device and the digital audio processing controller module of the portable device, the portable device can transmit control command packet to control the digital audio processing device. The user can use a large-size screen of the portable device to control the digital audio processing device to overcome the shortage in the display function of conventional device. Furthermore, when using the portable device under the condition where the hardware of the digital audio processing device is not changed, the functions of the digital audio processing device can be additionally extended. Therefore, the extended functions of the digital audio processing device can be flexibly added in response to customers and DJ's requirements.

Abstract: A method for operating cue points on a lighting ring of a digital multimedia audio player is revealed. A lighting ring for showing data related to digital music playing now is disposed around a turntable of a multimedia audio player. The lighting ring is arranged with a plurality of visual markers at important cue points by DJs for producing special sound effects while one of the cue point markers is set at a position that matches DJs' operation way and this is the position of an active cue point. Thereby during operation of the multimedia audio player, the obvious markers at the cue points allow DJs to operate the device easily and conveniently. Moreover, the active cue point can be set and adjusted according to different operation ways of DJs. Thus the present invention provides DJs with an intuitive reminder and convenient operation on the vision and the operational control.

Abstract: A device includes a turntable, a pickup, and a digital audio signal processor with a built-in compression/uncompression chip; in use, as soon as the pickup reads analogous audio signals of a vinyl record, the analogous audio signals will be converted into digital ones by means of an analog-to-digital converter, which are next sent to the digital audio signal processor, and compressed by means of the built-in chip of the digital audio signal processor, and stored in a large-capacity storage medium; afterwards, the digital audio signals are uncompressed by means of the chip, and converted into analogous ones by means of a digital-to-analog converter, which are next sent out through a low-pass wave filter.

Abstract: An audio signal player includes a turntable unit, a conductive touch-control plate on top of the turntable unit, a round disk, a round disk central shaft made of electricity-conductive materials and joined to the touch-control plate, a reflective-type photoelectric interrupter secured in the touch-control plate for finding out rotational speed and direction of the round disk, and a photoelectric interrupter in a lower end of the turntable unit for finding out rotational speed and direction of the turntable unit; when the round disk is manually rotated, the audio signal player will produce scratch sound effects according to the rotational speed and direction of the round disk; the user is allowed to touch the touch-control plate so as to produce a touch signal, thus making the audio signal player produce a particular scratch sound effect according to the touch signal.

Abstract: A digital audio signal player includes a microprocessor, a light producing ring, a digital audio signal processor, a dynamic RAM, and a manually-operated turning plate; the dynamic RAM is used to store music data; the light producing ring can produce light of several different colors, and it is joined to the turning plate and electrically connected to the microprocessor; the digital audio signal processor will analyze the rhythms of high-frequency portions and low-frequency portions of the digital music data stored in the dynamic RAM, and transfer the result of analysis to the microprocessor, and in turn the microprocessor will make the light producing ring shine and flash on and off with the colors of its light varying with the rhythms of the high-frequency portions and the low-frequency portions of the digital music data stored in the dynamic RAM.

Abstract: A digital audio signal player includes a CD support seat for holding a CD, a microprocessor, a laser pick-up, and a dynamic RAM; a CD supported on the CD support seat will rotate several times the normal speed, and the laser pick-up will read the CD when the microprocessor starts functioning; when the laser pick-up reads a CD, data of the CD will be transferred to and stored into the dynamic RAM; the dynamic RAM is divided into first and second sections, which are respectively used for storing music, which is currently being played, and for storing music that is to be played immediately after the current music is finished; therefore, the first and the second sections of the dynamic RAM can take turns to store music of different compact disks, thus preventing interruption of music playing from happening owing to a change of CD.

Abstract: An audio signal player includes a turntable unit, a conductive touch-control plate on top of the turntable unit, a round disk, a conductive central shaft joined to the touch-control plate and the round disk, an upright grating on a lower edge of the turntable unit, a flat grating joined to a lower end of the central shaft, a photoelectric interrupter for use with the upright grating to find out rotational speed and direction of the turntable unit, a photoelectric interrupter for use with the flat grating to find out rotational speed and direction of the round disk; the round disk can be manually rotated to send out scratch sound effects; the user is allowed to touch the touch-control plate so as to produce a touch signal, thus making the player send out, according to the touch signal, a particular one of various scratch sound effects.

Abstract: A player includes an actuating mechanism, and a touch-control plate; the actuating mechanism is joined to a turntable at an output shaft; the output shaft holds a central shaft therein, which has a conductive inner part, and an insulating outer part around the inner part, and which is connected to inside of the player; the central shaft is connected to a center of a round disk on the turntable; the round disk can be manually rotated to produce scratch sound effects; the touch-control plate is conductive, and joined to the central shaft such that a touch signal will be transferred to the player inside when the plate is touched; when the output shaft makes the turntable rotate, and the touch-control plate is touched to produce a touch signal, the player will, according to the touch signal, send out a particular one of various scratch sound effects stored in the player.
