Wireless audio playback device and wireless internet audio playback method

Abstract

The invention involves a wireless audio playback device, including the audio playback system, which includes: CPU module, storage module, playback module, sound module and wireless communication module.A wireless Internet audio playback method also provides the following steps: s1. Audio acquisition; S2. Audio storage; S3. Download and playback of audio.Large shortened the delay when playing audio playback, so that the playback of wireless audio equipment has high -fidelity sound quality, solving the slow speed of the existing audio signal, which delayed the signal transmission and the low sampling rate causes a large sound quality loss, so that the wireless wireless lossThe sound quality distortion of the audio equipment is high, the details of the details are large, and the sound quality is poor.

Description

technical field [0001] The present invention relates to the technical field of earphone audio playback, in particular, to a wireless audio playback device. Based on the wireless audio playback device, a wireless Internet audio playback method is also invented. Background technique [0002] Headphones and speakers use a pair of conversion units, which receive the electrical signals from the media player or receiver, and convert them into audible sound waves using speakers close to the ears. [0003] With the development of computer technology, the current headset and speaker products on the market have developed from wired to wireless. Music is transmitted to headphones or speakers through Bluetooth, and there are also online listening to songs through wifi. [0004] like Figure 8 As shown, at present, wireless audio devices such as Bluetooth headsets and Bluetooth speakers are wirelessly transmitted through Bluetooth. The playback mode of the wireless audio device is that ...

AI Technical Summary

Problems solved by technology

[0004] like Figure 8 As shown, at present, wireless audio devices such as Bluetooth earphones and Bluetooth speakers transmit wirelessly through Bluetooth. The played audio signal is transmitted to the wireless audio device, and the wireless audio device receives the audio signal through Bluetooth and plays the audio signal after decoding. The disadvantage of this audio playback method is that the signal is transmitted after being highly compressed, and its transmission distance is short and Low efficiency, low audio sampling rate, loss of sound quality during transmission, poor sound quality played by headphones or speakers

[0005] like Figure 9 As shown, there are currently wireless audio devices such as wireless earphones and wireless speakers on the market that transmit wirelessly through WiFi. WiFi directly transmits the audio signal played by the mobile terminal to the wireless audio device or transmits the audio signal played by the mobile terminal to the router through WiFi and then transmits it to the wireless audio device through WiFi. The audio signal is decoded and played. The disadvantage of this audio playback method is that the signal frequency occupancy rate is low, resulting in loss of sound quality during transmission, which affects the sound quality of the earphone playback.

[0006] The disadvantage of the above wireless playback method is that the audio signal data is compressed, and the bandwidth of the audio signal is small (less than 24BIT), which makes its transmission efficiency low, and the audio sampling rate is low (lower than 192KHZ), which leads to loss of sound quality during transmission, thus Affects the sound quality played by headphones, making the sound quality played from wireless audio devices highly distorted, with a lot of detail loss and poor sound quality
