Problems solved by technology

[0003] However, since the prior art speaker box basically has a cuboid shape, it is easy to form a clear standing wave by sound reflection from the inner wall
When the standing wave is contained in the speaker box, the disturbance of the sound characteristics tends to increase

[0021] Figure 1A is a perspective view of an electronic organ to which the speaker box structure according to the first embodiment of the present invention is applied. In this embodiment, the electronic organ 100 is taken as an example of the electronic device. This electronic keyboard 100 has a keyboard section KB. The direction in which the keys are arranged in the keyboard section KB is referred to as the lateral direction (left-right direction). The right and left sides are called based on the direction the player sees them. In the front-rear direction, the side where the keyboard part KB is provided is referred to as the front side.

[0022] The housing portion of the electronic organ 100 includes an upper housing 90, a lower housing 10 and a bottom plate 80 (reference will be made hereinafter Figure 3A with Figure 3B to describe). The housing portion is provided with a left speaker box spBL and a right speaker box spBR. Speaker boxes spBL, spBR have speakers SPL...

Abstract

A speaker box structure of an electronic device, includes: a left side speaker box having: a left side wall part; and a first opposed wall part which has a region where a distance in a lateral direction from the left side wall part to the first opposed wall part continuously varies; and a right side speaker box having: a right side wall part; and a second opposed wall part which is opposed to the first opposed wall part in an intermediate part in the lateral direction, and which has a region where a distance in the lateral direction from the right side wall part to the second opposed wall part continuously varies.

Description

technical field [0001] The invention relates to a speaker box structure of an electronic device, which comprises a left speaker box and a right speaker box. Background technique [0002] There are electronic musical instruments, audio equipment, etc. that include a left speaker box and a right speaker box. It is basically known that the bass becomes richer as the volume of the speaker enclosure increases. From this point of view, in Japanese Patent No.2541017, in order to increase the volume of the speaker box of the electronic organ as much as possible, it is proposed to increase the volume of the speaker box for the bass by utilizing the space below the keyboard and the panel. plan. In the bass reflex speaker device in JP-A-H10-13978, there is disclosed a design that minimizes the occurrence of noise due to fluid changes as sound in the region around the port. [0003] However, since the prior art speaker box basically has a cuboid shape, clear standing waves are easily...
