The invention discloses a control method and a control device, and the method comprises the steps: processing to-be-outputted audio data into first to-be-outputted audio data outputted through electronic equipment and second to-be-outputted audio data outputted through the audio equipment under the condition that the electronic equipment is in communication connection with at least one piece of audio equipment; and obtaining relative position information of the target object with the electronic equipment and the audio equipment, and controlling output parameters of the first to-be-outputted audio data and the second to-be-outputted audio data at least based on the relative position information. According to the method, the electronic equipment and the audio equipment which establish the communication connection are controlled to output the output parameters of the first to-be-output audio data and the second to-be-output audio data of different frequency bands respectively, so that the first to-be-outputted audio data and the second to-be-outputted audio data can reach the target object at the same time, the high and low pitch error caused by not arriving at the target object at the same time is avoided, and the sound effect of the sound field formed by the electronic equipment and the audio equipment is improved.
Description
technical field [0001] The present application relates to the technical field of audio transmission, and in particular to a control method and a control device. Background technique [0002] At present, the audio devices installed in electronic devices such as notebook computers and smart speakers all simulate the user's use scene to adjust the fixed speaker sound effect, and the same audio source can be played through multiple audio devices, for example, using three audio devices (two tweeters and a subwoofer) to form 2.1 channels to improve the audio quality received by the user. [0003] However, each audio device is in a different position, resulting in a different time to reach the same position, so that the treble signal and bass signal received by the user are not synchronized, that is, the audio information cannot be accurately and clearly restored for the user. Contents of the invention [0004] In the first aspect, the embodiment of the present application provi...
