Abstract

The present technology relates to a sound output control apparatus, a sound output control method, and a program that make it possible to perform control to prevent a balance of a system from being disturbed when reproduction is performed using a plurality of wireless speakers. A sound output control apparatus includes a transmitter that transmits first setting information regarding a sound output of the sound output control apparatus; a receiver that receives second setting information regarding a sound output of another sound output control apparatus; and a controller that controls a sound pressure or a reproduction frequency range in which reproduction is performed, on the basis of the first setting information or the second setting information. The first setting information and the second setting information each include at least information regarding a temperature, information regarding an amplitude, information regarding a remaining capacity of a power supply, and information regarding the reproduction frequency range. The present technology is applicable to, for example, a wireless speaker.

First claim

1 . A sound output control apparatus, comprising:
a transmitter that transmits first setting information regarding a sound output of the sound output control apparatus; a receiver that receives second setting information regarding a sound output of another sound output control apparatus; and a controller that controls a sound pressure or a reproduction frequency range in which reproduction is performed, on a basis of the first setting information or the second setting information.

2 . The sound output control apparatus according to claim 1 , wherein
the first setting information and the second setting information each include at least information regarding a temperature, information regarding an amplitude, information regarding a remaining capacity of a power supply, and information regarding the reproduction frequency range.

3 . The sound output control apparatus according to claim 2 , wherein
the information regarding a temperature is information regarding a gain set to be used to control a temperature of a speaker, and when the second setting information includes the information regarding a temperature, the controller controls the sound pressure on a basis of the gain.

4 . The sound output control apparatus according to claim 2 , wherein
the information regarding an amplitude is information regarding a gain set to be used to prevent a speaker from exhibiting an excessive amplitude, and when the second setting information includes the information regarding an amplitude, the controller controls the sound pressure on a basis of the gain.

5 . The sound output control apparatus according to claim 2 , wherein
the information regarding a remaining capacity of a power supply is information indicating that a voltage supplied to an amplifier has been increased or decreased, and when the second setting information includes the information regarding a remaining capacity of a power supply, the controller controls the amplifier of the sound output control apparatus on a basis of the information indicating that the voltage has been increased or decreased.

6 . The sound output control apparatus according to claim 2 , wherein
the information regarding the reproduction frequency range is information indicating that a specified reproduction frequency range in which reproduction is performed has been suppressed, and when the second setting information includes the information regarding the reproduction frequency range, the controller performs control to increase a sound pressure in the suppressed specified reproduction frequency range.

7 . The sound output control apparatus according to claim 2 , wherein
the information regarding the reproduction frequency range is information indicating that a system includes the sound output control apparatus reproducing a low-frequency sound or a high-frequency sound, and when the second setting information includes the information regarding the reproduction frequency range, the controller performs control to suppress the reproduction frequency range for the low-frequency sound or the high-frequency sound reproduced by the sound output control apparatus included in the system.

8 . The sound output control apparatus according to claim 7 , wherein
when the controller detects that the sound output control apparatus reproducing a low-frequency sound or a high-frequency sound and being included in the system has been removed from the system, the controller returns the suppressed reproduction frequency range to an unsuppressed state.

9 . A sound output control method, comprising:
transmitting, by a sound output control apparatus, first setting information regarding a sound output of the sound output control apparatus; receiving, by the sound output control apparatus, second setting information regarding a sound output of another sound output control apparatus; and controlling, by the sound output control apparatus, a sound pressure or a reproduction frequency range in which reproduction is performed, on a basis of the first setting information or the second setting information.

10 . A program that causes a computer to perform a process comprising:
transmitting first setting information regarding a sound output of a sound output control apparatus; receiving second setting information regarding a sound output of another sound output control apparatus; and controlling a sound pressure or a reproduction frequency range in which reproduction is performed, on a basis of the first setting information or the second setting information.
