Low-loss wireless Bluetooth headset

Abstract

The invention discloses a low-loss wireless Bluetooth headset. The headset includes a cigar head charger and a Bluetooth headset body; the cigar head charger is provided with a plurality of Bluetooth headset charging holes and a plurality of USB interfaces; an NFC chip is built in the Bluetooth headset body, the Bluetooth headset body includes a protection circuit, a second output port, a solar cell panel, a third output port, a power adapter, a lithium ion battery, a first output port and a headset part; the lithium ion battery is connected with the headset part through the first output port, the protection circuit is connected with the lithium ion battery through the third output port, and the solar cell panel is connected with the protection circuit through the second output port. The low-loss wireless Bluetooth headset is reasonable in design, high in resource utilization rate and high in working efficiency, the energy loss is reduced; the lithium ion battery can automatically store electric power through the solar cell panel, and it is ensured that the lithium ion battery has sufficient electricity before use; the occurrence of over-charging is avoided, and the service life of the lithium ion battery is prolonged.

Description

technical field [0001] The invention relates to a bluetooth earphone, in particular to a low-loss wireless bluetooth earphone. Background technique [0002] Bluetooth audio receivers have been on the market for many years. All receivers have a single system-on-a-chip integrated circuit to communicate with a Bluetooth transmitter from a smartphone, PC, or a stand-alone audio transmitter. At present, Bluetooth technology has penetrated into various industries, and users of Bluetooth headsets can be seen everywhere. Bluetooth headsets are generally charged with a 220V adapter power supply, which has great limitations. The inconveniences are as follows: 1. The battery capacity of the Bluetooth headset itself is not high, and the power consumption is large. In addition to the loss of power in the buck-boost circuit, the use time is short and frequent charging is required; 2. When answering important calls Headphone battery warning, resulting in loss. 3. When the Bluetooth hea...
