Based on the above embodiments, the present invention provides a control method for an audio system.
Referring to fig. 5, fig. 5 is a flowchart illustrating a control method of an audio system according to a first embodiment of the present invention.
As described in the above embodiments, the sound system includes the master enclosure and the slave enclosure. As shown in fig. 5, the present embodiment proposes a control method of a sound system, which is applied to a main speaker, and includes the following steps:
s10, after receiving an access signal of a sound source device, the main sound box acquires a first signal intensity of the access signal;
s20, receiving a second signal strength sent by the slave loudspeaker, where the second signal strength is the strength of an access signal of the sound source device received by the slave loudspeaker;
s30, when the second signal strength is greater than the first signal strength, sending notification information to the slave loudspeaker box, wherein when the slave loudspeaker box receives the notification information, the slave loudspeaker box switches to the temporary master loudspeaker box and establishes connection with the sound source device;
and S40, receiving and playing the sound source data sent by the temporary main sound box.
In an embodiment, the sound source device may be a wireless sound source device or a USB sound source device, and as described in the above embodiments, the master speaker and the slave speaker each include an audio signal wireless transceiver module and a USB interface module, that is, when the sound source device is a wireless sound source device or a USB sound source device, the sound source device may be connected to the master speaker or the slave speaker.
Further, taking the sound source device as a wireless sound source device as an example, after the sound system is powered on and started up, the main sound box may first detect whether there is an access signal that the sound source device requests to access the sound system, and if so, the main sound box obtains the first signal intensity of the access signal.
Furthermore, as the slave loudspeaker box is also provided with the audio signal wireless transceiver module and the USB interface module, when the sound source equipment initiates an access application, the slave loudspeaker box also acquires an access signal of the sound source equipment and acquires the second signal intensity of the access signal. The main sound box, the slave sound box and the wireless sound source equipment are easily blocked by distances, interferents and the like, so that the access signal strength of the wireless sound source equipment transmitted to the main sound box and the slave sound box is different, namely the first signal strength is different from the second signal strength. Or, when there are multiple slave speakers in the sound system, the second signal strengths of the sound source device access signals obtained from the multiple slave speakers are different.
Further, when the slave loudspeaker box obtains a second signal strength of the access signal, the second signal strength is sent to the master loudspeaker box, and the master loudspeaker box receives the second signal strength sent by the slave loudspeaker box. Because when the signal intensity of the access signal of wireless sound source equipment is the biggest, it shows that the sound source data that the audio amplifier equipment that corresponds received from wireless sound source equipment is more clear, complete, consequently receiving behind the second signal intensity that follows the audio amplifier and send, the size of the signal intensity in first signal intensity and the second signal intensity need be judged to main audio amplifier to be connected the audio amplifier equipment that signal intensity is the biggest with sound source equipment, so that the audio frequency of broadcast in the sound system is more clear, complete, can not be intermittent.
Further, when the second signal strength is greater than the first signal strength, the master speaker transmits notification information to the slave speaker, wherein when the slave speaker receives the notification information, the slave speaker switches to the temporary master speaker and establishes connection with the sound source device.
Further, when the number of the slave loudspeaker boxes in the sound system is set to be one, the first signal intensity and the second signal intensity are directly compared, when the second signal intensity is greater than the first signal intensity, the slave loudspeaker box corresponding to the second signal intensity is switched to the working mode of the temporary master loudspeaker box through the equipment state defining module, and the slave loudspeaker box is connected with the sound source equipment.
Further, when the sound system includes at least two slave speakers, and when the second signal strength is greater than the first signal strength, the master speaker acquires the largest second signal strength of the received second signal strengths, and sends notification information to the slave speaker corresponding to the largest second signal strength. Specifically, the master loudspeaker acquires the number of the second signal intensities larger than the first signal intensity, that is, acquires the second signal intensities corresponding to the slave loudspeakers larger than the signal intensity of the master loudspeaker, and compares the second signal intensities in the slave loudspeakers, so as to use the slave loudspeaker corresponding to the largest second signal intensity in the second signal intensities as the slave loudspeaker connected to the sound source device, that is, send notification information to the slave loudspeaker corresponding to the largest second signal intensity, so that the slave loudspeaker corresponding to the largest second signal intensity is switched to the working mode of the temporary master loudspeaker through the device state definition module, and establishes connection between the slave loudspeaker and the sound source device.
Further, the notification information includes address information of a slave speaker in the sound system, and the temporary master speaker transmits the sound source data to other slave speakers except the temporary master speaker in the sound system according to the address information, so that the temporary master speaker can exercise temporary control authority given by the master speaker, that is, all other slave speakers in the sound system can be controlled.
Further, after the address information of all the slave loudspeaker boxes is acquired, the address information is sequenced, and the sequenced address information is stored in the first storage module of the master loudspeaker box in a form of a table, so that the master loudspeaker box subsequently controls the slave loudspeaker boxes corresponding to the address information, or all the address information except the slave loudspeaker boxes with the temporary master loudspeaker box permission is sent to the temporary master loudspeaker box, so that the temporary master loudspeaker box controls the slave loudspeaker boxes corresponding to the address information. Certainly, the temporary main speaker can only receive the control information sent by the main speaker and cannot be used for controlling the main speaker; however, the temporary master speaker may send the sound source data to the master speaker and each slave speaker through the second audio signal wireless transceiver module, and the master speaker may receive the sound source data sent by the temporary master speaker through the first audio signal wireless transceiver module.
Further, for example, the sound source device is a wireless sound source device, in the process of playing a sound source by the sound system, along with the change of the position of the wireless sound source device, the master speaker may receive the signal intensity of the wireless sound source device detected by the multiple slave speakers in real time, the master speaker gives the temporary master device permission to the slave speaker with the maximum signal intensity in real time according to the received signal intensity of the wireless sound source, in order to ensure the playing quality of audio in the permission transfer process of the temporary master device, in this embodiment, the master speaker and the slave speakers both adopt a mode of separately transmitting a control signal and an audio signal, that is, a first audio signal wireless transceiver module and a first control signal wireless transceiver module are disposed in the master speaker in this embodiment, and a second audio signal wireless transceiver module and a second control signal wireless transceiver module are disposed in the slave speaker.
Further, after the slave loudspeaker box is connected with the sound source equipment, the slave loudspeaker box receives sound source data of the sound source equipment, and at the moment, the slave loudspeaker box and the master loudspeaker box are both provided with audio processing modules, so that the slave loudspeaker box can directly send the received sound source data to the master loudspeaker box, or send the received sound source data of the sound source equipment to the master loudspeaker box after processing. At this time, the master speaker may receive the unprocessed sound source data or the processed sound source data sent by the slave speaker, and play the unprocessed sound source data after processing or directly play the processed sound source data sent by the slave speaker.
In an embodiment of the present invention, the method for controlling the audio system includes the steps of: the method comprises the steps that after the main sound box receives an access signal of sound source equipment, first signal intensity of the access signal is obtained; receiving a second signal strength sent by the slave loudspeaker box, wherein the second signal strength is the strength of an access signal of the sound source equipment received by the slave loudspeaker box; when the second signal intensity is greater than the first signal intensity, sending notification information to the slave loudspeaker box, wherein when the slave loudspeaker box receives the notification information, the slave loudspeaker box is switched to a temporary master loudspeaker box and connection with the sound source equipment is established; each is received and broadcast from audio amplifier and main audio amplifier the sound source data that interim main audio amplifier sent, can be through the access signal intensity of sound source equipment promptly, according to signal intensity, select to switch from the mode of operation of audio amplifier to interim main audio amplifier to by each audio amplifier equipment broadcast audio frequency of interim main audio amplifier control sound system, thereby improve the signal intensity of the sound source data that obtains from sound source equipment, improve sound system's performance.
Further, referring to fig. 6, a second embodiment of the control method of an acoustic system according to the present invention is proposed based on the first embodiment of the control method of an acoustic system, and in this embodiment, after the step of receiving the second signal strength transmitted from the loudspeaker, the control method of an acoustic system further includes:
