Signal Processing Device, Signal Processing Method, and Sound Emitting System
First Claim
1. A signal processing device for supplying sound signals to a first speaker for emitting a sound on a low-pitched sound side and a second speaker for emitting a sound on a high-pitched sound side higher than the low-pitched sound side, comprising:
- a control portion that controls a characteristic of the sound signal supplied to the first speaker so that an output level of the first speaker is maintained at a crossover frequency between the first speaker and the second speaker when an output level of the sound signal supplied to the first speaker is changed.

9. A sound emitting system, comprising:
-
a first speaker that emits a sound on a low-pitched sound side; a second speaker that emits a sound on a high-pitched sound side higher than the low-pitched sound side; and a signal processing portion that supplies sound signals to the first speaker and the second speaker; wherein, when an output level of the sound signal supplied to the first speaker is changed, the signal processing portion controls a characteristic of the sound signal supplied to the first speaker so that an output level of the first speaker is maintained at a crossover frequency between the first speaker and the second speaker. - View Dependent Claims (10, 11, 12)
