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

Embodiment Construction
[0022]Various aspects and various embodiments of the present invention will now be described. The following description provides specific details to thorough understanding and implementation of these embodiments. However, those skilled in the art will appreciate that the present invention may be implemented without these details. Additionally, some well-known structures or functions may not be disclosed or described in detail to avoid unnecessary to confuse the relevant description.
[0023]figure 1 It is a schematic diagram showing a system 1000 including a first speaker 100 and a second speaker 200 of the present invention. Such asfigure 1 As shown, the first speaker 100 includes a first DAC 120, coupled to the first counter 130 of the first DAC 120, coupled to the first receiver 140 of the first DAC 120, coupled to the calculator 150 of the first receiver 140, coupled to the first The first clock 110 of the receiver 140 is coupled to generator 160 of the calculator 150, coupled to t...

The present invention relates to an apparatus and method for synchronizing speakers, wherein a first speaker includes a receiver configured to receive a second running audio file from the second speaker when the first speaker plays an audio file synchronized with the second speaker. time and a second number of audio files; a calculator configured to calculate a time interval value based on a second run time; a generator configured to generate a modified second number of audio files based on the time interval value; a comparator configured to a difference between the second number of audio files corrected in pairs and the first number of audio files of the first speaker to determine an amount of delay for the first speaker; an adjuster configured to adjust a playback speed of the first speaker; and an output terminal configured to output the audio file according to the adjusted playback speed. The synchronous speaker provided by the present invention can effectively and accurately control the playback speed of the first speaker and the second speaker, so that the two can play the same audio file synchronously, which greatly eliminates the problem of playback delay between the two speakers, and through the algorithm Control saves hardware costs.
Description
Technical field[0001]The present invention relates to a synchronous speaker, more specifically, but is not limited to, in particular, a device and method for synchronizing speakers in a wireless network.Background technique[0002]With the development of wireless technology, in some cases, two conventional speakers are typically a primary speaker and a sub speaker that needs to be coupled in a continuous manner through a wireless connection. However, since the two speakers start playing audio files at different times, and the clocks of each of the digital analog converters (DACs) in both speakers are not precisely synchronized, and 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 for processing the above problems and delays between the main speaker and the sub speaker.Inventive content[0003]An embo...
