Description

[Detailed description of the invention] [Industrial field of application] The present invention relates to speaker boxes that require airtightness, and is particularly aimed at preventing mechanical and design problems in wiring between upper and lower devices when stacked in multiple tiers. It is something to do.

[Conventional technology]

In order to increase the acoustic effect, a bass reflex type speaker box in which the speaker is connected to the opening by a meandering duct has an airtight structure as shown in FIG. 2, for example. Figure a is a vertical sectional view, figure b is a
In this sectional view taken along the line A-A, 1 is an outer casing, 2 is an opening thereof, 3 and 4 are partitions forming an internal labyrinth for a duct, and 5 is a speaker for bass. speaker 5
The airtightness of the duct is important in order for the sound pressure dissipated in the front direction to be transmitted in the direction of the arrow in the duct 6 and exit to the opening 2. If this is insufficient, sound leakage will occur, and the No significant sound enhancement effect can be expected.

[Problems to be solved by the invention] Such bass reflex type speaker boxes are sometimes used by being stacked between other devices.
For example, there is a case where an amplifier power supply section is arranged below the speaker box and a radio player section is arranged above it. In such a case, it is necessary to lay the wiring from the lower amplifier power supply section to the upper radio player section, bypassing the intermediate speaker box section. If this is done on the back in general, the cords passing through the outside will be noticeable and will not be aesthetically pleasing. It is also possible to run the wiring through the inside of the speaker box, but in this case, manual work is required to ensure airtightness, making it difficult to mass-produce.

[Means for solving problems]

In order to solve the above-mentioned drawbacks, the present invention provides an airtight speaker box installed between a lower device and an upper device, which includes an outer casing for accommodating a speaker, and a predetermined portion of the outer casing. It is characterized by comprising a recess formed by recessing the inside of the recess, and a decorative panel covering the opening side of the recess, and a cord is inserted through the recess to connect the upper and lower devices. It is something.

[Effect]

A recess into which a cord can be pushed from the outside is formed in a predetermined part of a speaker box, and its surface is covered with a decorative panel. In this way, the wiring between the lower and upper devices of the speaker box can be laid without any mechanical or design problems.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows an embodiment of the present invention, in which a is a top view of a speaker box, b is a front view with a decorative panel removed, and c is an enlarged perspective view of the main parts. In the figure, 10 is an amplifier power supply section (lower device), 20 is a bass reflex type speaker box, and 30 is a radio player section (upper device), and these are stacked in multiple stages with the speaker box 20 in the middle as shown in b. be done. The speaker box 20 is roughly divided into an outer casing 21 and a front decorative panel 22, as shown in a, and the outer casing 21 is formed with one or more recesses 23 for inserting a cord. c is an enlarged view of this part.

In general, the inner wall of a bass reflex speaker box in areas where air flow and sound pressure are low (for example, the end on the front opening side) may lack flatness to a certain extent, but this will have little effect on the acoustic characteristics. Therefore, if the recess 23 is provided in such a portion, the acoustic characteristics will not be further deteriorated.

The recess 23 is formed integrally with a part of the outer casing 21 made of resin by pressing, and at the same time, a plurality of line processing claws 24 that partially protrude toward the opening side of the recess 23 are also formed. A pipe 25 is pushed into the recess 25 through the gap between the claws 24, and a cord 26 is inserted into the pipe in advance. There are connectors 2 on both ends of the cord 26.
7 is attached and used for connection between the amplifier power supply section 10 and the radio player section 30. Since the decorative panel 22 of a covers the surface of the outer casing 21, the recess 23 and therefore the cord 26 etc. are not visible from the outside.

Although the line processing claw 24 and the pipe 25 are not necessarily necessary, the claw 24 helps to hold the pipe 25 (cord 26) with its elasticity, and the pipe 25
prevents the cord 26 from escaping from the recess 23.

[Effect of idea]

As described above, according to the present invention, when a speaker box that requires airtightness is installed in the middle position and electronic devices are installed above and below and the electronic devices are connected using cords, the cords are connected to the outside. There is an advantage that the speaker box does not need to be laid in a position where it can be seen from the outside and does not affect the airtightness of the speaker box.

[Brief explanation of the drawing]

Fig. 1 is a configuration diagram showing one embodiment of the present invention;
The figure is a sectional view of a bass reflex type speaker box. In the figure, 10 is the lower device, 20 is the speaker box, 21 is its outer casing, 22 is a decorative panel, 23 is a recess, 24 is a wire processing claw, 25 is a pipe, 26 is a cord, 27 is a connector, and 30 is a This is the upper device.
