Audio output device capable of switching a sound field

Abstract

An audio output device includes a housing, a speaker, a switching unit, a fixing component and a control unit. An opening is formed on the housing. The speaker is for outputting sound. The switching unit is installed inside the housing. The fixing component is fixed in the opening of the housing for triggering the switching unit so that the switching unit outputs a switching signal. The control unit is electrically connected to the switching unit and the speaker, and the control unit controls the speaker to output sound in a corresponding sound field as the control unit receives the switching signal.

What is claimed is: 
     
       1. An audio output device comprising:
 a housing, an opening being formed on the housing; 
 a speaker for outputting sound; 
 a switching unit installed inside the housing; 
 a fixing component fixed in the opening of the housing for pressing to trigger the switching unit so that the switching unit outputs a switching signal; and 
 a control unit electrically connected to the switching unit and the speaker, the control unit controlling the speaker to output sound in a corresponding sound field mode as the control unit receives the switching signal. 
 
     
     
       2. The audio output device of  claim 1 , wherein the control unit comprises a general purpose input/output (GPIO) port electrically connected to the switching unit. 
     
     
       3. The audio output device of  claim 2 , wherein the switching unit is grounded to output a low level switching signal to the general purpose input/output port, as the fixing component is fixed in the opening and presses to trigger the switching unit. 
     
     
       4. The audio output device of  claim 1 , wherein the control unit amplifies amplitude of a high frequency audio signal output from the speaker so as to control the speaker to output the sound in a wall-mounting sound field mode, as the control unit receives the switching signal. 
     
     
       5. The audio output device of  claim 4 , wherein the control unit does not amplify the amplitude of the high frequency audio signal output from the speaker so as to control the speaker to output the sound in a standing sound field mode, as the fixing component is not fixed in the opening of the housing. 
     
     
       6. The audio output device of  claim 1 , wherein the switching unit is a push switch. 
     
     
       7. The audio output device of  claim 1 , wherein the opening is a thread opening, and the fixing component is a wall-mounting screw for screwing the housing on a wall-mounting bracket. 
     
     
       8. The audio output device of  claim 1 , being a television device. 
     
     
       9. An audio output system comprising:
 a wall-mounting bracket installed on a supporting plane, a hole being formed on the wall-mounting bracket; and 
 an audio output device comprising:
 a housing, an opening being formed on the housing; 
 a speaker for outputting sound; 
 a switching unit installed inside the housing; 
 a fixing component fixed in the opening of the housing for pressing to trigger the switching unit so that the switching unit outputs a switching signal; and 
 a control unit electrically connected to the switching unit and the speaker, the control unit controlling the speaker to output sound in a corresponding sound field mode as the control unit receives the switching signal. 
 
 
     
     
       10. The audio output system of  claim 9 , wherein the control unit comprises a general purpose input/output (GPIO) port electrically connected to the switching unit. 
     
     
       11. The audio output system of  claim 10 , wherein the switching unit is grounded to output a low level switching signal to the general purpose input/output port, as the fixing component is fixed in the opening and presses to trigger the switching unit. 
     
     
       12. The audio output system of  claim 11 , wherein the control unit amplifies amplitude of a high frequency audio signal output from the speaker so as to control the speaker to output the sound in a wall-mounting sound field mode, as the control unit receives the switching signal. 
     
     
       13. The audio output system of  claim 12 , wherein the control unit does not amplify the amplitude of the high frequency audio signal output from the speaker so as to control the speaker to output the sound in a standing sound field mode, as the fixing component is not fixed in the opening of the housing. 
     
     
       14. The audio output system of  claim 13 , wherein the switching unit is a push switch. 
     
     
       15. The audio output system of  claim 14 , wherein the opening is a thread opening, and the fixing component is a wall-mounting screw for screwing a wall-mounting bracket on the housing. 
     
     
       16. The audio output system of  claim 9 , wherein the audio output device is a television device. 
     
     
       17. The audio output system of  claim 9 , wherein the control unit amplifies amplitude of a high frequency audio signal output from the speaker so as to control the speaker to output the sound in a wall-mounting sound field mode, as the control unit receives the switching signal. 
     
     
       18. The audio output system of  claim 17 , wherein the control unit does not amplify the amplitude of the high frequency audio signal output from the speaker so as to control the speaker to output the sound in a standing sound field mode, as the fixing component is not fixed in the opening of the housing. 
     
     
       19. The audio output system of  claim 9 , wherein the switching unit is a push switch. 
     
     
       20. The audio output system of  claim 9 , wherein the opening is a thread opening, and the fixing component is a wall-mounting screw for screwing a wall-mounting bracket on the housing.
