Abstract

An audio apparatus includes a main body, a plurality of speakers provided in the main body, a storage section configured to store a conversion table which indicates a correspondence between postures of the main body and control contents of audio signals to be supplied to the speakers, and a control section configured to refer to the conversion table of the storage section, and control the audio signals to be supplied to the speakers in accordance with a posture of the main body.

Claims

1. An audio apparatus comprising:

a main body;

a plurality of speakers provided in the main body;

a receiving section on the main body configured to receive an external device and receive posture information of the external device from the external device, the external device providing audio signals to said plurality of speakers and including a posture detector configured to generate the posture information;

a storage section configured to store a conversion table which indicates a correspondence between postures of the external device and control contents of audio signals to be supplied to the speakers; and

a control section configured to refer to the conversion table of the storage section, and control the audio signals to be supplied to the speakers in accordance with the posture information of the external device received by the receiving section.

2. The audio apparatus according to claim 1, further comprising:

a supply destination information receiving section that receives supply destination information indicative of supply destinations of the audio signals, from the external device,

wherein the control section configured to determine the speakers of the supply destinations of the audio signals, based on the supply destination information received by the supply destination information receiving section.

3. The audio apparatus according to claim 1, wherein the control section configured to control channels of the audio signals to be supplied to the speakers.

4. The audio apparatus according to claim 1, wherein the control section configured to control bands of the audio signals to be supplied to the speakers.

5. The audio apparatus according to claim 1, further comprising:

a content receiving section which receives content data from the external device,

wherein the control section configured to supply the audio signals to the speakers to reproduce the content data.

6. The audio apparatus according to claim 1, further comprising:

a connector provided on the housing,

wherein the connector is configured that the external device is attached thereto in the same posture as that of the main body.

7. A method of changing a sound emission mode of an audio apparatus, comprising:

receiving at a receiving section on the main body of the audio apparatus, the receiving section being configured to receive an external device, audio signals and posture information of the external device from the external device, the external device including a posture detector configured to generate the posture information;

referring to a conversion table stored in a storage section, wherein the conversion table indicates a correspondence between postures of the external device and control contents of audio signals to be supplied to speakers provided in the main body; and

controlling the audio signals to be supplied to the speakers in accordance with the posture information of the external device received from the external device and the correspondence of the conversion table.

8. The method according to claim 7, further comprising:

receiving supply destination information indicative of supply destinations of the audio signals, from the external device,

determining the speakers of the supply destinations of the audio signals, based on the supply destination information received from the external device.

9. The method according to claim 7, wherein in the controlling process, channels of the audio signals to be supplied to the speakers are controlled.

10. The method according to claim 7, wherein in the controlling process, bands of the audio signals to be supplied to the speakers are controlled.

11. The method according to claim 7, further comprising:

receiving content data from the external device; and

supplying the audio signals to the speakers to reproduce the content data.
