Abstract

PURPOSE:To plan to make a tone quality high with a simple constitution, by releasing a sound from a speaker box installed behind a PACHINKO machine from an opening portion of the front face of the PACHINKO machine through a duct or a phone. CONSTITUTION:Communicting holes of a speaker box 22 and a PACHINKO machine 2 are communicated by a duct 24, whereby a sound produced from a speaker unit 23 into the speaker box 22 is released to the outside from the communicating hole of the PACHINKO machine 2 through the duct 24. Here, as the speaker unit 23 housed within the speaker box 22, one with a relatively large bore can be used, so that it becomes possible to enlarge a reproduction range and a reproduced sound from the speaker unit 23 is released to the outside through the duct 24, thereby improving a low sound range. Since the speaker box is disposed behind the PACHINKO machine where there is a relatively vacant space, a degree of freedom in place for disposing the speaker box can be increased, and the restriction in size of the speaker unit can be accordingly lessened.

Embodiments of the present invention will be described below in detail with reference to the drawings. In the drawings described below, the same parts as those in FIG. 1 are designated by the same reference numerals.

FIG. 2 shows a pachinko machine according to an embodiment of a speaker system for a pachinko machine of the present invention.
As shown in the figure, on the game board 3 of the pachinko machine 2 of the pachinko machine 1, various winning openings 4 to 7 and starting openings 8 to 10 for starting the fluctuation of the symbols on the display unit 11 are provided. The pachinko balls stocked in the upper plate 14 are turned one by one by turning the handle 13, and when one wins at the winning board 4 to 7 or the starting opening 8 to 10, the inside of the pachinko machine 1 is played. Speaker unit (not shown)
An electronic sound is emitted from.

Further, when a pachinko ball is won in the starting ports 8 to 10 and the symbols variably displayed on the display unit 11 are aligned, the big winning port 12 arranged below the display unit 11 is selected. It is set to open for a certain period of time.

A communication hole 21a for a duct 24, which will be described later, is provided below the upper plate 14, which is the lower portion of the pachinko machine base 2. The location of the communication hole 21a is not limited to this example, and the lower plate 15 may be provided as indicated by reference numeral 21b.
On the lower side, above the communication hole 21 as indicated by reference numeral 21c, or in any case where various parts such as the lower tray 15 on the front side of the pachinko machine 2 are not provided. It can be optionally provided.

FIG. 3 shows an arrangement state of the speaker system inside the pachinko machine 1. The one-chamber type speaker box 22 of the speaker system 20 is inside the housing 1A behind the pachinko machine 2. It is arranged. Here, since there is a relatively large amount of extra space inside the housing 1A, the speaker box 22 can be installed at an arbitrary location.

The speaker box 22 and the communication hole 21a of the pachinko machine 2 are communicated with each other by the duct 24, and the sound emitted from the speaker unit 23 inside the speaker box 22 travels through the duct 24 and is transmitted to the pachinko machine. It is discharged to the outside through the two communication holes 21a.
