The present invention is provided with an amplifier, a tuner, a cassette deck, a compact disc deck, and the like on each side of a square body to form a main front, and the front panel is installed inside an audio equipment case having an operation part and an opening to be desired as a remote controller. The present invention relates to a main front drive device for an acoustic device in which the portion is located in the opening, thereby facilitating its use.

As is well known, acoustic devices such as audio were used separately in the form of amplifiers, tuners, cassette decks, and compact disc decks, with the fronts facing the front, stacked and placed in the proper position in the room. As dust accumulates on the part, and the dust enters the inside of the device, not only the sound quality is deteriorated but also the life of the device is shortened.

Therefore, the present invention solves the above-mentioned drawbacks as described above, and forms an amplifier, a tuner, a cassette deck, and a compact disc deck on each side of one rectangular body, and installs them in a case provided as a remote controller. In order to provide a main front drive device for an acoustic device that rotates by 90 ° so that only the portion to be used appears in the opening of the case so that dust and the like can be localized. The detailed description is as follows.

Insert a "+" in the center of the upper part of the cylindrical acoustic equipment main body (3) with the bass speaker (1) to emit sound in all directions at the lower part, and the mid and high speaker (2) (2 ') at the left and right sides. The hole 4 is drilled, and the rotor shaft 8 formed by forming the four blade pieces 5 at 90 ° in the lower portion of the insertion hole 4 and the fixing portion 6 and the insertion rod 7 at the upper portion thereof. To insert and install a motor (not shown) freely rotated forward and reverse in the lower part of the rotary shaft (8), and installed a rotation sensor (9) in the lower portion of the insertion hole (4) of the "+" type When the rotary shaft 8 is operated by a remote controller (not shown), the main front body can be rotated forward and backward by exactly 90 °, and fixedly inserted into the fixing part 6 and the insertion rod 7. 10, the fixing groove 11 and the insertion hole 12 are also formed in the center of the bottom of the bottom surface, and on each side of the main front body 10, an amplifier, a tuner, a cassette deck and a compact disc. After forming the decks and the like, and assembling them on the rotary shaft 8, the main body for the acoustic device is assembled by assembling the main body case 3 with the main front case 15 having the opening 13 and the operation portion 14 in front. It's a front drive.

Reference numeral 16 is a tightening screw, and 17 is a turntable.

Referring to the operation and effects of the present invention as described above are as follows.

A well-known motor is installed in the center of the cylindrical sound device main body 3 so as to be free to rotate left and right, and a rotary shaft 8 is installed in the motor so as to be remotely controlled as a remote controller. Since the main front body 10 made of a rectangular body having a tuner, an amplifier, a cassette deck and a compact disc deck is fixed, the main front body 10 can be easily rotated left and right by remote control operation. The main front, which needs to be rotated by 90 ° precisely by 90 °, can be accurately positioned as an opening of the case 15, and the bottom of the insertion hole 4 of the "+" type to detect this and achieve correct operation. Since the rotation sensor 9 detects the blade 5 fixed at an angle of 90 ° to the lower part of the rotation shaft 8, the rotation sensor 9 rotates by 90 ° accurately during forward and reverse rotation. Tuners, amplifiers, cassette decks, and compact disc decks, which are formed on each side of the chassis body 10, can only be attached to the power switch, etc. uniformly formed on the operation unit 14 of the case 15, thereby improving the efficiency of the operation of the device. And convenience.

As described above, the present invention has a tuner, an amplifier, a cassette deck, and a compact disc deck formed on each side of the main front body 14 formed in a quadrangular body, and are formed on the rotary shaft 8 which is built up inside the acoustic device body 3. The case 15 is assembled after the left and right rotations can be accurately adjusted as a remote control unit, and the use of the case 15 is very convenient and only the necessary parts are seen through the front opening 13 of the case 15. It is a very useful design that can minimize the inflow and extend the life of the device, as well as the simple structure, which causes very few failures and induces user curiosity.
