Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a cabinet device for audio equipment such as a tape recorder.

(B) Prior art In a tape recorder in which the operating knob is operated from the top surface of the cabinet that constitutes the equipment, in order to make the operating knob protrude from the top surface, for example, the actual opening 59-45.
As disclosed in Japanese Patent Publication No. 976 (H05K5 / 02), a front structure and a rear structure are combined with a chassis structure in which an operation knob is projected upward, and a top surface cabinet is separately prepared and combined. Was doing.

(C) Problems to be solved by the invention In the conventional cabinet device configured as described above, a speaker is attached to the inner surface of the front cabinet, and the chassis structure arranged so as to be sandwiched between the front and rear cabinets, Parts are provided on the side facing the front cabinet and on the side facing the rear cabinet, respectively.

This is because the components provided on the chassis structure, such as the cassette mounting component of the tape recorder mechanism and the tuning display component of the radio, are exposed from the front cabinet.

Therefore, when the front cabinet with the speaker attached and the chassis structure are combined, the escape space of the chassis structure is located at the back of the speaker, and the parts of the chassis structure disturb the rear air pressure of the speaker, which results in good acoustic characteristics. Was something I couldn't get.

Further, when assembling and disassembling the chassis structure with respect to the front cabinet, the parts exposed from the front cabinet are obstructive and the work is difficult. For this reason, when the outer surface of the front cabinet is matte and non-reflective coating (velvet coating) is applied, the outer surface coating may be damaged when the chassis structure is assembled and disassembled.

(D) Means for solving the problems The present invention solves the problems when the above-mentioned coating is applied to the outer surface of the front cabinet, the rear cabinet and the deck panel to give a soft-feeling texture finish. For this purpose, the outer surface is matted and has a non-reflective coating, and the front cabinet is formed with speaker sound emission holes, and the outer surface is matted and has a non-reflective coating, and is assembled to the front cabinet. A deck panel and a rear cabinet, and a mixture of calcium carbonate in a polystyrene resin molding material, the outer surface of which adheres to the inner surface of the front cabinet and a speaker sound emission hole is formed, and a speaker on the inner surface which does not adhere to the front cabinet, Main chassis to which electronic parts etc. are mounted, and the same material as the main chassis A sub-chassis that seals the speaker facing the speaker sound output hole and is attached to the inner surface of the main chassis, and increases the effective thickness of the front cabinet by the close contact of the main chassis. The present invention provides a cabnet device for an audio device, characterized in that it is configured to match.

(E) Operation According to the device of the present invention, parts such as a speaker, an electronic part, and a tape recorder mechanism are assembled on the inner surface side of the main chassis in a preparatory work step, and then the main chassis is assembled so that the outer surface thereof is in close contact with the front cabinet.

At this time, the front cabinet and the main chassis overlap with each other to substantially increase the thickness of the speaker mounting portion, and the speaker is sealed by the sub chassis.

(F) Embodiment An embodiment of the device of the present invention shown in the drawings will be described below. (1) is a front cabinet with a matte, non-reflective coating on the outer surface and speaker sound output holes (2), (3) and (4) formed, and (5) of the front cabinet (1) It is a decorative panel mounted on the surface. (6) and (7) are a deck panel and a rear cabinet, which are assembled on the front cabinet (1) with a matt and non-reflective coating on the outer surface.

The front cabinet (1) , the deck panel (6) and the rear cabinet (7) are made of ABS resin, and the outer surfaces are coated with a paint composed of "Bervex black / velvet hardener / velvetx thinner ^# 1500". It is a thing.

The deck panel (6) is provided with an operation button group (8) and a cassette insertion opening (9) for inserting a cassette (not shown) downward from above. (10) is a main chassis molded from a material in which calcium carbonate is mixed with polystyrene molding resin material, the outer surface is molded so as to be in close contact with the inner surface of the front cabinet (1) , and the speaker sound output hole (11) ( 12) and (13) are formed.

(14), (15) and (16) are a mid-high range speaker, a low-pitched speaker and a mid-high range speaker that are attached to the inner surface side of the main chassis (10) that is not in close contact with the front cabinet (1) .

(17) is also a tape recorder mechanism attached to the inner surface side of the main chassis (10) , and the mechanism (17) receives the cassette inserted from the insertion opening (9) of the deck panel (6) from above and is in a playing state. It is configured to.

(18) is a Sabushiyashi attached to Meinshiyashi (10) so that the made of the same material as Meinshiyashi (10) to seal surrounds the back of the bass-only speaker (15).

(19) is an amplifier substrate attached to the inner surface of the main chassis (10) , and (20) is a tuner substrate attached to the sub chassis (18).

Therefore, the assembly of the device of the present invention having the above-mentioned structure will be described.

First, as a first step, a speaker for mid-high range sound (14), a speaker for low-pitched sound (15) and a medium sound are provided on the inner surface side of the main chassis (10) so as to face the speaker sound output holes (11), (12) and (13). The treble speaker (16) is attached, and particularly for the bass only speaker (15), the subchassis (18 ) is attached to the main chassis (10) so as to be sealed by the subchassis (18). Then, the tape recorder mechanism (17) is attached to this main chassis (10 ).
Amplifier board (19) and tuner board
By attaching (20), the main chassis (10) can be recorded and played back as a semi-finished product.

In the second step, the main chassis (10) to which the parts are attached as described above is combined with the front cabinet (1) to which the decorative panel (5) is attached. At this time, the main chassis (10)
The outer surface of the is closely contacted with the inner surface of the front cabinet (1) .

Then, in the third step, the deck panel (6) is fitted to the front cabinet (1) from above.

As the final step, the rear cabinet (7) is fitted to the front cabinet (1) and the deck panel (6) and screwed.

Through the above steps, the assembly of the cabinet can be completed.

By the above assembling, the speaker sound emission hole (11) (12) (13) of Meinshiyashi (10) is a speaker sound emission hole (2) in front Kiyabinetsuto (1) (3) (4) and becomes substantially matching condition , The speaker mounting part is in a state where the main chassis (10) and the front cabinet (1) overlap and the effective thickness is increased, especially the speaker for low-pitched sound (15) is sealed by the sub chassis (18). Has become.

Therefore, even if the speaker for low-pitched sound (15) vibrates, the thickness of the speaker mounting portion is thick, so that unnecessary vibration does not occur and the rear air pressure of the speaker for low-pitched sound (15) is disturbed. Absent.

(G) Effect of the device Since the device of the present invention is configured as described above, it is possible to improve the acoustic characteristics by using a material in which calcium carbonate is mixed with the polystyrene resin molding resin material for the main chassis and the sub chassis. Since the main chassis is a semi-finished product, the front front cabinet, deck panel, and rear cabinet are assembled, so that the matte and anti-reflective coating can be assembled without damaging the outer surface. .

Further, according to the present invention, since the main chassis and the front panel are superposed in close contact with each other, the speaker mounting portion can be made to act as a thick baffle plate, and unnecessary vibration is not generated. Bass can be reproduced.

Further, since the parts attached to the main chassis are not exposed on the front cabinet side, it is easy to assemble and disassemble.
