That is, since the speaker units are not too close to each other, excellent omnidirectionality can be obtained even in the vertical direction which is the vertical direction of the display. Thereby, the effect of virtual sound using crosstalk cancellation or the like can be obtained in a wide range. Therefore, the user can listen to a sound having excellent omnidirectionality even at a position shifted from the front of the speaker system.
- the two identical speaker units are disposed so that the sound wave emission surfaces face each other, vibrations can be canceled. Thereby, unnecessary vibration noise caused by a cabinet other than the speaker can be prevented. Therefore, it is possible to prevent the chattering sound of the casing caused by a large volume. Further, by canceling the vibration, it is possible to prevent the Doppler effect due to the vibration of the main body of the video display device or the like provided with the speaker system.
- the speaker system has an effect that the frequency characteristic of the sound pressure is small in a wide range, that is, it can output sound having excellent omnidirectionality.
