The word "if" as used herein may be interpreted as "at … …" or "when … …" or "in response to a determination", depending on the context.
Fig. 1 is a flowchart illustrating a device control method according to an exemplary embodiment, in which the method illustrated in fig. 1 is applied to an audio system including a first audio device and a second audio device, the method including:
in step 101, wireless signals transmitted by a terminal are received using a first audio device and a second audio device, respectively.
In the embodiment of the disclosure, the audio device has a function of playing audio and a function of receiving a wireless signal sent by a terminal. The audio device may be a sound box.
The Wireless signal transmitted by the terminal may be a short-wave signal, for example, a UWB (Ultra Wide Band) signal, a BT (bluetooth) signal, a WIFI (Wireless Fidelity) signal, an ultrasonic signal, or the like.
In step 102, a difference between the characteristic information of the wireless signal received by the first audio device and the characteristic information of the wireless signal received by the second audio device is determined.
The characteristic information of the wireless signal is characteristic information that the wireless signal exhibits during propagation, such as propagation distance, propagation time, propagation speed, reception time, signal strength, and the like of the wireless signal.
Accordingly, the difference between the characteristic information of the wireless signal received by the first audio device and the characteristic information of the wireless signal received by the second audio device may be a propagation distance difference, a propagation time difference, a reception time difference, a signal strength difference, and the like.
In one embodiment, a propagation distance of the wireless signal from the terminal to the first audio device is referred to as a first propagation distance, a propagation distance of the wireless signal from the terminal to the second audio device is referred to as a second propagation distance, and the first propagation distance and the second propagation distance are subtracted to obtain a propagation distance difference of the wireless signal.
In this embodiment, the difference includes a propagation distance difference. The wireless signal transmitted by the terminal may carry the transmission time of the wireless signal.
The audio system may determine a first receiving time for the first audio device to receive the wireless signal, obtain a sending time carried by the wireless signal, determine a first time difference between the first receiving time and the sending time, and multiply the first time difference by a propagation speed of the wireless signal to obtain a first propagation distance for the wireless signal to propagate from the terminal to the first audio device.
The audio system may determine a second receiving time for the second audio device to receive the wireless signal, obtain a sending time carried by the wireless signal, determine a second time difference between the second receiving time and the sending time, and multiply the second time difference by the propagation speed of the wireless signal to obtain a second propagation distance for the wireless signal to propagate from the terminal to the second audio device.
In one embodiment, the wireless signal transmitted by the terminal carries the transmission time of the wireless signal. The audio equipment can receive wireless signals sent by the terminal at different moments, and the sending time carried by the wireless signals sent at different moments is different.
In a case where each of the wireless signals received by the first audio device and the second audio device carries the transmission time of the respective signal, the sound box system may determine, based on the transmission time carried by each of the wireless signals, a difference between the characteristic information of the wireless signal received by the first audio device and the characteristic information of the wireless signal received by the second audio device and transmitted at the same time. Therefore, the wireless signals transmitted at different moments are distinguished and processed.
For example, the terminal sequentially sends wireless signals at three indoor positions, the sending time carried by the wireless signals sent at different moments is different, and the audio device can determine the wireless signals sent at the same moment according to the sending time carried by the wireless signals and determine the corresponding difference of the wireless signals sent at the same moment.
In step 103, when the audio system plays audio, the phase difference between the audio signals output by the first audio device and the second audio device is adjusted according to the difference, so that the terminal receives the audio signals output by the first audio device and the second audio device simultaneously.
In one embodiment, the audio system determines a propagation time difference of the audio signals according to the difference, the propagation time difference is a difference between a first propagation time and a second propagation time, the first propagation time is a time for the audio signals to propagate from the first audio device to the terminal, the second propagation time is a time for the audio signals to propagate from the second audio device to the terminal, the audio system controls the first audio device to output the audio signals, and after the propagation time difference, controls the second audio output audio signals so that the terminal receives the audio signals output by the first audio device and the second audio device at the same time. In the above process, the propagation time difference is greater than zero.
In this embodiment, the characteristic information may include a propagation distance of the wireless signal, and the difference may include a difference in the propagation distance of the wireless signal. The process of determining the propagation distance difference of the wireless signal can refer to the description in step 102.
Typically, the difference in propagation distance of the wireless signals is equal to the difference in propagation distance of the audio signals. The audio system may divide the difference in propagation distance of the wireless signal by the propagation speed of the audio signal to obtain the difference in propagation time of the audio signal.
In a fixed propagation medium, the propagation speed of an audio signal is fixed. For example, the propagation velocity of an audio signal is about 340m/s at 1 atm and 15 ℃ in air.
For example, the distance between the terminal and the first audio device is 4m, the distance between the terminal and the second audio device is 2m, the propagation speed of the audio signal in the air is 340m/s, and based on this, the propagation time difference of the audio signal is determined
And controlling the first audio equipment to output the audio signal, and controlling the second audio equipment to output the audio signal after the time t, so that the terminal receives the audio signals output by the first audio equipment and the second audio equipment at the same time.
In one embodiment, the time when the first audio device receives the wireless signal is called a first receiving time, the time when the second audio device receives the wireless signal is called a second receiving time, and the first receiving time and the second receiving time are subtracted to obtain the receiving time difference of the wireless signal.
In this embodiment, the characteristic information may include a reception time of the wireless signal, and the difference may include a reception time difference of the wireless signal.
Based on this, the loudspeaker system can determine the propagation time difference of the audio signals by the following means: firstly, multiplying the receiving time difference of the wireless signals by the propagation speed of the wireless signals to obtain the propagation distance difference of the wireless signals, wherein the propagation distance difference of the wireless signals is equal to the propagation distance difference of the audio signals, and then dividing the propagation distance difference of the audio signals by the propagation speed of the audio signals to obtain the propagation time difference of the audio signals.
In one embodiment, the first audio device and the second audio device each comprise a speaker array having the function of determining the direction of propagation of the signal.
Based on this, the audio system can adjust the phase difference of the audio signals output by the first audio device and the second audio device by: under the condition that the first audio equipment and the second audio equipment receive wireless signals sent by terminals at different positions, the phase difference of the audio signals output by the two loudspeaker arrays is adjusted according to the corresponding difference of the wireless signals sent at different positions, so that the terminal at each position simultaneously receives the audio signals output by the two loudspeaker arrays. Thus, users at different positions can obtain the best listening effect.
For example, a combined sound box is arranged indoors, each sound box in the combined sound box is provided with a speaker array, two persons respectively use mobile phones to send wireless signals, the combined sound box adjusts the phase difference of audio signals output by the two speaker arrays according to the corresponding difference of the wireless signals sent at different positions, so that the mobile phones at each position all receive the audio signals output by the two speaker arrays at the same time, and users at each position all can obtain the best listening effect.
In one embodiment, the first audio device and the second audio device are connected under the same router to form a local area network and then establish communication, wherein one audio device acquires the characteristic information of the wireless signal or the information for determining the characteristic information and sends the characteristic information of the wireless signal or the information for determining the characteristic information to the other audio device.
And the other audio equipment determines the difference according to the information sent by the one audio equipment and the information acquired by the self equipment, determines the time for the one audio equipment to start outputting the audio signal according to the difference, determines the time for the self equipment to start outputting the audio signal, and sends the time for the one audio equipment to start outputting the audio signal to the one audio equipment so that the one audio equipment starts outputting the audio signal when the time is reached.
Through interaction between the two audio devices, the audio signals output by the first audio device and the second audio device simultaneously reach the terminal.
In the embodiment of the disclosure, an audio system receives wireless signals sent by a terminal by using first audio equipment and second audio equipment respectively, determines a difference between characteristic information of the wireless signals received by the first audio equipment and characteristic information of the wireless signals received by the second audio equipment, and adjusts a phase difference of the audio signals output by the first audio equipment and the second audio equipment according to the difference when the audio system plays audio, so that the terminal receives the audio signals output by the first audio equipment and the second audio equipment at the same time. The user uses the terminal to send wireless signals, and triggers the audio system to automatically adjust the phase difference of the audio signals output by the two audio devices, so that the user can obtain the optimal listening effect. By the method, the user carrying the terminal can obtain the best listening effect at different positions, and the user experience is very good.
