However, since the two speakers start playing the audio file at different times, and the clocks of the digital-to-analog converters (DACs) of each of the two speakers are not precisely synchronized, the two speakers often have different packet loss , there is a delay between the main speaker and the sub speaker, so the audience may have a relatively poor hearing experience

The present invention relates to an apparatus and a method for synchronizing speakers. The first speaker comprises a receiver, wherein the receiver is configured to receive a second runtime and a second number of audio files from the second speaker when the first speaker plays an audio file synchronized with the second speaker; a calculator, wherein the calculator is configured to calculate a timeinterval value according to the second runtime; a generator, wherein the generator is configured to generate a corrected second number of audio files according to the time interval value; a comparator, wherein the comparator is configured to compare the difference value between the corrected second number of audio files and a first number of audio files of the first speaker so as to determine theamount of delay of the first speaker; an adjuster, wherein the adjuster is configured to adjust the playing speed of the first speaker; and an output end, wherein the output end is configured to output the audio files according to the adjusted playing speed. According to the apparatus and method for synchronizing speakers provided by the present invention, the playing speeds of the first speakerand the second speaker can be effectively and precisely controlled, so that the two speakers can synchronously play the same audio file, the problem of the play delay existing between the two speakersis greatly eliminated, and the hardware cost can be controlled and saved through the algorithm.
Description
technical field [0001] The present invention relates to a synchronous loudspeaker, more particularly, but not limited to, a device and method for synchronizing loudspeakers in a wireless network. Background technique [0002] With the development of wireless technology, in some cases, two conventional speakers, usually a main speaker and a sub speaker, need to be coupled together in a continuous manner through a wireless connection. However, since the two speakers start playing the audio file at different times, and the clocks of the digital-to-analog converters (DACs) of each of the two speakers are not precisely synchronized, the two speakers often have different packet loss , there is a delay between the main speaker and the sub speaker, so the audience may have a relatively poor hearing experience. Therefore, it is desirable to provide an apparatus and method that can deal with the above-mentioned problems and minimize the possibility of delay between the main speaker a...
