DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a housing used for electronic equipment such as a portable radio and a portable radio.

[0002]

2. Description of the Related Art Conventionally, housings shown in FIG. 5 and those shown in FIG. The housing shown in FIG. 5 has a rectangular cylindrical case body e into which an operation unit b can be inserted from above and a radio unit d having a speaker c mounted on the front of the chassis a. The case body e includes a detachable battery part f, and a large number of small holes g for emitting sound emitted from the speaker c of the wireless unit d are opened on the front surface of the case body e. ing.

[0006] The housing shown in FIG. 6 has a structure in which a speaker c of a wireless unit d housed in a case body e is attached to the case body e.

[0004]

However, in the former case, the case body e is moved while the wireless unit d is slid.
Due to the internal structure, the adhesion between the speaker c attached to the wireless unit d and the case body e is poor, and as a result, there is a problem that the sound pressure and the sound quality are reduced. In the latter case, since the speaker c is attached to the case body e, the speaker c is difficult to be attached and detached, and the mounting efficiency of the chassis part b is poor.

An object of the present invention is to provide a housing of an electronic device in which a speaker can be easily attached and detached and the sound pressure and the sound quality are not deteriorated.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention accommodates a wireless unit and has a battery at the bottom.
A case body with a removable part and an opening on the front,
Attach acoustic components such as speakers and microphones on the back,
A front panel detachably attachable to the opening and a front
A frame that is electrically connected to the audio component and the wireless unit.
With a cable, and opening the front panel.
The optional unit from the opening to the wireless unit
It is attached to.

[0007]

According to the above construction, the sound quality and sound pressure of the acoustic component are not reduced by the case body, and the detachment of the acoustic component can be easily performed by removing the front panel.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described in detail with reference to the drawings shown in FIGS. In these figures, 1 is a case body, 2 is a wireless unit housed in the case body 1,
Reference numeral 3 denotes a front unit detachably mounted on the front surface of the case main body 1, and reference numeral 4 denotes a battery unit detachably mounted on the bottom of the case main body 1.

The case body 1 is formed in a rectangular cylindrical shape having an upper surface and a front surface opened.
The case body 1 is fixed to the wireless unit 2 by a set screw 6 screwed into the chassis 2a of the wireless unit 2 from the bottom surface of the case body 1.

An operation panel 2 is provided on the upper surface of the chassis 2a of the wireless unit 2 so as to close the upper opening of the case body 1.
b, and a liquid crystal display device 7 is provided on the upper front surface of the chassis 2a so as to be exposed through a liquid crystal display window 1a formed on the front surface of the case body 1. A press button 8 is provided on a side surface of the case body 1, and a front panel unit 3 is detachably attached to an opening 1b which is largely opened on the front surface.

The front panel unit 3 has a front panel 3b on one end side on which a locking piece 3a is provided so as to engage with the opening 1b of the case body 1. The front panel 3b
Is provided with a numeric keypad sheet switch 9 and a number of small holes 3c, and a fixing piece 3 is provided at the other end of the front panel 3b.
The front panel unit 3 is inserted into the opening 1b of the case body 1 by screwing a set screw 10 inserted from the bottom surface of the case body 1 into the screw hole 3e of the fixing piece 3d. It can be fixed.

On the other hand, the wireless board 11 housed in the chassis 2a of the wireless unit 2 has the opening 1 of the case body 1 with the wireless unit 2 housed in the case body 1.
The recording / reproducing unit 1 is attached by a set screw 13 from b.

The recording / reproducing unit 12 is provided with a connector 15 connected to a connector 14 provided on the wireless board 11 side. The wireless board 11 and the recording / reproducing unit 12 are connected via these connectors 14 and 15. A connector 16 is provided on the wireless board 11 for electrical connection, and the connector 16 is connected to the front panel 3b.
A speaker 17 and a microphone 18 attached to the back surface of the camera 10 and the numeric keypad sheet switch 9 and the like are connected via a flexible cable 19.

A pair of slide rails 1e are formed on the bottom surface of the case body 1, and the battery section 4 is attached to the case body 1 by inserting the battery section 4 along these slide rails 1e. It is supposed to be.

Next, the operation of the above-structured housing will be described. When the wireless unit 2 is housed in the case body 1 with the front panel unit 3 removed as shown in FIG.
The bottom surface of the case body 1 is fixed to the wireless unit 2 with a set screw 6.

Next, after connecting the front panel unit 3 and the connector 16 of the wireless board 11 with the flexible cable 19 through the opening 1b of the case body 1, the recording / reproducing unit 12 is inserted through the opening 1b as shown in FIG. Then, the recording / reproducing unit 12 is fixed to the wireless board 11 with the set screw 13.

After that, the engaging piece 3a protruding from one end of the front panel 3b is engaged with the opening 1a of the case body 1 as shown in FIG. 3, and the front panel unit 3 is fitted into the opening 1a. By screwing into the fixing piece 3d of the front panel 3b into which the set screw 10 is inserted from the bottom of the case body 1,
As shown in FIG. 4, the front panel unit 3 is
In use, the battery unit 4 may be further attached to the bottom of the case body 1 to supply electricity to the wireless unit 2 from the battery unit 4.

By opening the front panel unit 3 by the reverse operation, the options of the recording and reproducing unit 12 and the like can be easily exchanged.

[0019]

According to the present invention as the present invention has been described in detail above, the scan copy
Make sure that the sound quality and sound pressure of
Which problems could be solved and the front panel was opened
The option unit can be installed in the
Optional unit and radio
The entire function can be checked easily, and maintenance and maintenance
To obtain an excellent effect that can improve
Can be done.

Further, since a speaker or the like can be mounted with the front panel removed from the case body, the speaker can be easily mounted and the front panel can be opened as compared with a conventional case where the speaker is directly mounted on the case body. By doing so, it becomes possible to easily exchange optional units and the like.
