Speaker device

Abstract

In order to obtain a speaker device in which the localization point of a sound source is located at a distant place, providing a feeling of expanse (deepness) without involving an oppressive feeling due to sound pressure, and a good operability that makes it possible to reproduce sounds with frequency characteristics covering the high frequency range, and to achieve size reduction, there is provided a speaker device designed so that the sounds from speakers (2L, 2R) are emitted obliquely rearward to be reflected by reflection plates (8L, 8R) pivotally mounted on the back plates (7L, 7R) of a speaker cabinet (1L, 1R), the reflected sounds being directed to the audience.

Description

technical field [0001] The present invention relates to a loudspeaker device in which a reflecting plate is hingedly installed on the back of a sound box, etc., and particularly relates to a loudspeaker device in which a speaker unit emits sound obliquely rearward, and the sound is reflected by the reflecting plate before being listened to. Background technique [0002] Speakers 2L, 2R are installed inside the left and right speakers 1L, 1R, and are placed in front of the listener; the left and right speaker openings 4L, 4R pass through the left and right speakers 1L, 1R. Acoustic panel side, placed towards listener 3. [0003] Like this, following the sound L that enters the listener's 3 left ear 5L from the left speaker 2L, the same sound L' enters the right ear 5R after a very short delay. Similarly, the sound R from the right speaker 2R first enters the right ear 5R close to the right speaker 2R, and then after a delay, the sound R' reaches the left ear 5L. Therefore, f...

Problems solved by technology

[0004] For the existing sound box, as shown in Figure 12B, there are control devices for operating the sound box, such as a switch 18 for turning on and off the power supply, a volume adjustment knob 19, a bass knob 20 for controlling the low range, and a knob 21 for switching input, etc. The control devices are arranged on the front panels 25 of the speakers 1L, 1R to improve operability, but for the left and right speaker devices 10L, 10R, in order to install the left and right speakers 2L, 2R on the top of the control devices, the speakers 1L, 1R, The area of ​​the front panel 25 of 1R is larger than that of the speaker devices 2L and 2R of the present invention shown in FIG.

Someone once imagined designing the control device on the upper panel or the left and right side panels of the speakers 1L and 1R, but this will increase the area of ​​the upper panel or the left and right side panels, and it is inconvenient to use
