Method for sharing audio by Bluetooth headsets

Abstract

The invention relates to the field of electronic communication and particularly relates to a method for sharing an audio by Bluetooth headsets. The method comprises the following steps of (1) connecting a first Bluetooth headset with audio output equipment with a Bluetooth function in a paired manner through a Bluetooth module; (2) connecting the first Bluetooth headset with a second Bluetooth headset in a paired manner; (3) transmitting an audio signal on the audio equipment to the first Bluetooth headset, and then, transmitting the audio signal to the second Bluetooth headset through the first Bluetooth headset. The method is free of additional modules, relatively low in cost and capable of meeting the requirement for sharing the audio at long distance.

Description

Technical field [0001] The present invention relates to the field of electronic communication, in particular to a method for sharing audio using Bluetooth headsets. Background technique [0002] Bluetooth technology is a low-cost, low-power and short-range wireless communication technology, which can be widely used in headsets. Through the Bluetooth headset, users can avoid the annoying wire ties, and can talk easily in various ways. [0003] However, Bluetooth headsets in the prior art can generally only be connected to the audio output device Bluetooth one-to-one, for example, only one Bluetooth headset can be connected to a mobile phone. Due to the limitations of Bluetooth protocol, system performance and power consumption, it will be quite difficult to achieve one-to-many connections; even if one Bluetooth device is connected to multiple headsets, the number of Bluetooth headsets that can be connected will be limited . [0004] With the popularity of various mobile smart termi...

[0005] For example, "A Bluetooth headset and a method for sharing audio using the Bluetooth headset" disclosed by the National Patent Office of China on November 13, 2013, its publication number is CN103391118. This patent requires two Bluetooth modules to be installed in a Bluetooth headset. Realize the audio sharing between bluetooth earphones, so just need to increase the production cost of bluetooth earphone, make the production cost higher; And this bluetooth earphone patent structure only has increased a bluetooth module, and other modules are all the same as common bluetooth earphones on the market Similarly, because the Bluetooth headsets on the market do not have the audio sharing function, and because of power consumption considerations, the power amplification of the RF power amplifier unit used in the Bluetooth headsets on the market is relatively small, that is, it can generally only transmit a distance of about 10 meters. Therefore, the Bluetooth headset in this patent can only transmit at a distance of about 10 meters, which cannot meet the needs of long-distance audio sharing.
