Abstract

PROBLEM TO BE SOLVED: To reduce the number of processes, to reduce the production cost and to improve productivity without separately providing any hole for passing a speaker cable by providing a bass reflex port hole and a hole for the speaker and passing the speaker cable through the bass reflex port hole. SOLUTION: A game machine housing 30 is provided with a monitor 38 at an upper part, two speaker boxes 10 at a central part and space for housing PCB rack 40 at a lower part. The PCM rack 40 is usually hidden by closing a maintenance door 36. A speaker cable 16 is passed inside the game machine housing 30 at the place hidden by a net 34 for the speaker and the maintenance door 36, and connected to an amplifier PCB 42 installed inside the PCB rack 40. Since the net 34 for the speaker really uses fine punched metal, a game player does not notice internal conditions.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a speaker system,
In particular, phase inversion type (hereinafter, referred to as bass reflex in this specification)
The present invention relates to a speaker box suitable for use in a speaker.

[0002]

2. Description of the Related Art In a conventional bass reflex speaker box, a bass reflex port hole 14 is provided on the front face of the speaker box as shown in FIG.

However, in the conventional bass reflex speaker box, it was necessary to separately provide a hole for passing a speaker cable. If a hole is provided in addition to the port, air leaks from the hole, and the effect of the bass reflex is reduced. Therefore, a step of filling a gap in the hole through which the cable passes is necessary.

[0004]

By providing a hole for passing a cable as described above, a step of making a hole in the speaker box is required once more, and a step of filling the gap is required. This increases the number of steps, leading to a rise in production costs and a decrease in productivity.

[0005]

In order to solve the above problems, a speaker box according to the present invention has a bass reflex port hole and a speaker installation hole, and a speaker cable is passed through the bass reflex port hole. It is characterized in that a hole for passing a speaker cable is not provided.

[0006]

FIG. 1 shows an example of a speaker box according to the present invention. Speaker box 10
Is provided with a port hole 14 for bass reflex and a hole 15 for speaker installation. The speaker 12 is attached to the speaker installation hole 15. The speaker cable 16 attached to the speaker 12 passes through the port hole 14 and communicates with the outside.

[0007]

FIG. 3 shows a speaker box according to the present invention.
This shows an example in which the present invention is used for an arcade video game machine. In this embodiment, the speaker box is
Since it is integrated with 0, it cannot be removed.

The game machine housing 30 has a monitor 38 at the top,
Two speaker boxes 10 at the center and PCB at the bottom
A space for accommodating the rack 40 is provided. The PCB rack 40 is normally invisible by closing the maintenance villa 36. Speaker cable 1
Reference numeral 6 denotes a place hidden by the speaker net 34 and the maintenance billboard 36, which passes through the inside of the game machine housing 30 and is connected to an amplifier PCB 42 installed in a PCB rack 40. In FIG. 3, the speaker net 34 is drawn coarse so that the speaker box can be easily understood. However, in actuality, since a fine-punched metal is used, the game user may notice the inside. Is unlikely.

[0009] The present invention is not limited to the above example, and various methods of use can be considered, such as using it as a built-in speaker of a television receiver.

[0010]

By making a speaker box with the above-described configuration, the number of places where holes are made in the speaker box is reduced by one, and the number of steps of filling the cushioning material for filling the gap is reduced. And the processing cost can be saved.
