Abstract

An audio system utilizes a method for detecting and adjusting a sound field effect thereof. The audio system includes a first speaker and a second speaker. The first speaker is used to emit a first sound signal, and the second speaker is used to emit a second sound signal. The method for adjusting the sound field effect includes the steps of detecting a specific position and adjusting the first speaker or the second speaker based on the specific position to focus the first sound signal and the second sound signal on the specific position.

Claims

1. An audio system comprising:

a first speaker for emitting a first sound signal;

a second speaker for emitting a second sound signal;

a receiver located at a specific position and used to receive the first sound signal and the second sound signal to generate at least one feedback signal;

a controller electrically connected to the first speaker and the second speaker, respectively;

a first focusing reflector for reflecting the first sound signal;

a second focusing reflector for reflecting the second sound signal;

a first radian adjuster for adjusting the radian of the first focusing reflector; and

a second radian adjuster for adjusting the radian of the second focusing reflector, wherein the controller rotates the first speaker and the second speaker based on the at least one feedback signal to allow the first sound signal emitted by the first speaker and the second sound signal emitted by the second speaker to focus on the specific position, wherein the first sound signal and the second sound signal focus on the specific position via the first focusing reflector and the second focusing reflector, respectively, wherein the controller controls the first radian adjuster or the second radian adjuster to adjust the radian of the first focusing reflector or the second focusing reflector, respectively.

2. The audio system according to claim 1, wherein the receiver operates the controller in a wired or wireless mode.

3. The audio system according to claim 1, wherein the first radian adjuster and the second radian adjuster adjust the radians of the first focusing reflector and the second focusing reflector via steel ropes.

4. The audio system according to claim 1, wherein the first radian adjuster and the second radian adjuster are step motors.

5. The audio system according to claim 1 further comprising:

a first direction adjuster for adjusting the rotary angle of the first speaker; and

a second direction adjuster for adjusting the rotary angle of the second speaker;

wherein the controller is capable of controlling the first direction adjuster or the second direction adjuster to adjust the rotary angle of the first speaker or the second speaker.

6. The audio system according to claim 5, wherein each of the first direction adjuster and the second direction adjuster is a step rotor.

7. A method for detecting and adjusting a sound field effect for an audio system comprising:

emitting a first sound signal from a first speaker;

emitting a second sound signal from a second speaker;

generating at least one feedback signal by a receiver located at a specific position and receiving the emitted first sound signal and the second sound signal;

rotating the first speaker and the second speaker based on the at least one feedback signal and controlling the first sound signal emitted by the first speaker and the second sound signal emitted by the second speaker to focus on the specific position; and

adjusting a radian of a first focusing reflector or a second focusing reflector based on the at least one feedback signal to allow the first sound signal and the second sound signal to focus on the specific position, wherein adjusting the radian of the first focusing reflector or the second focusing reflector comprises;

controlling a first radian adjuster to adjust the radian of the first focusing reflector;

or

controlling a second radian adjuster to adjust the radian of the second focusing reflector.

8. The method according to claim 7, wherein rotating the first speaker or the second speaker comprises:

controlling a first direction adjuster to adjust a rotary angle of the first speaker;

or

controlling a second direction adjuster to adjust a rotary angle of the second speaker.
