1. Field of the Invention
The present disclosure is to provide an audio output device, and more specifically, to an audio output device capable of switching a sound field when being installed in a wall-mounting mode.
2. Description of the Prior Art
A flat-screen television (TV) can be installed in a wall-mounting mode or a standing mode. Practically, there is much difference in outputting sound as the flat-screen television is installed in the wall-mounting mode or in the standing mode. In general, the flat-screen TV is often set in the standing mode as a default setting of the standard sound field mode, which is regarded as being installed in the standing mode, and a speaker of the flat-screen TV is facedown in the standing mode so that a supporting surface, such as a ground or a desk, can be a reflective surface for the sound. However, there is no reflective surface for the speaker as the flat-screen TV is installed in the wall-mounting mode, resulting in lack of quality of high frequency audio signals. It is necessary to adjust the sound field mode for the flat-screen TV installed in the wall-mounting mode to amplify the high frequency audio signals, such as manually switching the sound field mode by a user. Hence, it is an important issue to design a simple mechanism for correspondingly switching the sound field to amplify the high frequency audio signals as the flat-screen TV is installed in the wall-mounting mode, and for automatically restoring to the standard sound field mode as the flat-screen TV is installed in the standing mode.
The present disclosure is to provide an audio output device capable of switching a sound field when installing in a wall-mounting mode, to solve the above drawbacks.
According to the disclosure, the 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 pressing to trigger 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 mode as the control unit receives the switching signal.
According to the disclosure, the control unit includes a general purpose input/output (GPIO) port electrically connected to the switching unit.
According to the disclosure, 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.
According to the disclosure, 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.
According to the disclosure, 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.
According to the disclosure, the switching unit is a push switch.
According to the disclosure, the opening is a thread opening, and the fixing component is a wall-mounting screw for screwing the housing on a wall-mounting bracket.
According to the disclosure, the audio output device is a television device.
According to the disclosure, an audio output system includes a wall-mounting bracket and an audio output device. The wall-mounting bracket is installed on a supporting plane, and a hole is formed on the wall-mounting bracket. The 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 pressing to trigger 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, the control unit controls the speaker to output sound in a corresponding sound field mode as the control unit receives the switching signal.
The audio output system controls the speaker to output sound in the wall-mounting sound field mode by simply fixing the fixing component on the housing to press the switching unit, in the present disclosure. When the fixing component is not fixed on the housing and does not trigger the switching unit, the speaker can output sound in the standard standing sound field mode, that is, the audio output system is installed in the standing mode. The simple-structured fixing component can achieve both functions of fixing the housing on the wall-mounting bracket and triggering the switching unit to switch the sound field mode simultaneously, so that the inconvenience in switching the sound field mode manually by a user in a conventional system is improved.
These and other objectives of the present disclosure will no doubt become obvious to those of ordinary skill in the art after reading the following detailed description of the preferred embodiment that is illustrated in the various figures and drawings.

Step 100: Actuate the audio output device 50.
Step 102: Determine if the fixing component 58 is fixed in the opening 521 of the housing 52. If yes, go to step 104; if no go to step 108.
Step 104: The fixing component 58 presses to trigger the switching unit 56 so that the switching unit 56 outputs the switching signal to the control unit 60.
Step 106: The control unit 60 controls the speaker 54 to output sound in the corresponding sound field mode as receiving the switching signal.
Step 108: Do not change the sound field mode.
Step 110: End.
The above-mentioned steps are introduced in detail as follows. Please refer to
After the audio output device 50 is actuated, the switching unit 56 is not pressed by the fixing component 58 so that the sound field mode output by the speaker 54 is not changed, when the switching unit 56 is not pressed by the fixing component 58. When the fixing component 58 is fixed in the opening 521 of the housing 52, the fixing component 58 is designed to press to trigger the switching unit 56, so that the switching unit 56 output the switching signal to the control unit 60. The control unit 60 then controls the speaker 54 to output sounds in a corresponding sound field mode as receiving the switching signal. For example, the switching unit 56 is not grounded and output a high level switching signal to the GPIO port of the control unit 60, as the switching unit 56 is not pressed and not triggered by the fixing component 58. The control unit 60 does not amplify amplitude of a high frequency audio signal output from the speaker 54, so as to control the speaker 54 to output the sound in a standing sound field mode. The switching unit 56 is grounded to output a low level switching signal to the GPIO port, as the fixing component 58 is fixed in the opening 521 and presses to trigger the switching unit 56. The control unit 60 receives the corresponding switching signal, and the control unit 60 amplifies amplitude of a high frequency audio signal output from the speaker 54 so as to control the speaker 54 to output the sound in a wall-mounting sound field mode. That is, the frequency response of the speaker 54 is switched from the standard standing sound field mode to the wall-mounting sound field mode for high acoustic quality.
One of preferred embodiments is introduced above, and the present disclosure is not limited to this. For another example, the switching unit 56 can output a high level switching signal to the GPIO port of the control unit 60, as the fixing component 58 is fixed in the opening 521 of the housing 52 and presses to trigger the switching unit 56. And the switching unit 56 is grounded to output a low level switching signal to the GPIO port of the control unit 60, as the fixing component 58 is not fixed in the opening 521 of the housing 52. In addition, the sound field modes of the audio output device 50 are not limited to the wall-mounting sound field mode and the standing sound field mode, and it depends on the practical requirements. That is, the mechanism, which utilizes the fixing component 58 to be fixed on the opening 521 of the housing 52 for triggering the switching unit 56 so as to switch the sound field mode output by the speaker 54, is within the scope of the present disclosure.
In contrast to the prior art, the audio output system controls the speaker to output sound in the wall-mounting sound field mode by simply fixing the fixing component on the housing to press the switching unit, in the present disclosure. When the fixing component is not fixed on the housing and does not trigger the switching unit, the speaker can output sound in the standard standing sound field mode, that is, the audio output system is installed in the standing mode. The simple-structured fixing component can achieve both functions of fixing the housing on the wall-mounting bracket and triggering the switching unit to switch the sound field mode simultaneously, so that the inconvenience in switching the sound field mode manually by a user in a conventional system is improved.
Those skilled in the art will readily observe that numerous modifications and alterations of the device and method may be made while retaining the teachings of the disclosure. Accordingly, the above disclosure should be construed as limited only by the metes and bounds of the appended claims.
