Head-mounted Bluetooth interphone

Abstract

The invention discloses a head-wearing type Bluetooth interphone. The head-mounted Bluetooth interphone structurally comprises a clamping plate, a headband, a movable rotating shaft, earmuffs, a magnetic shielding structure and a microphone; one end of the headband is movably contacted with the clamping plate; the other end of the headband is movably matched with the earmuffs through movable rotating shafts; a magnetic shielding structure is installed in each earmuff. The microphone is movably contacted with the earmuffs; the magnetic shielding structure is composed of a stabilizing frame and a shielding ring; the stabilizing frame is of a ring-shaped structure; the outer ring of the stabilizing frame is provided with a shielding ring; an electronic device is mounted in the stabilizing frame; the shielding ring is formed by sequentially overlapping a first metal sheet, a second metal sheet and a third metal sheet; through the combined action of the shielding ring and the stabilizing frame, on one hand, magnetic field demagnetization is conducted through the annular shielding ring, and on the other hand, the electronic device and the shielding ring are fixed through the stabilizing frame, so that it is guaranteed that the positions of the electronic device and the shielding ring do not deviate due to vibration, and the magnetic field intensity demagnetization effect is not affected.

Description

technical field [0001] The invention relates to the field of bluetooth, in particular to a head-mounted bluetooth walkie-talkie. Background technique [0002] Unlike traditional wired walkie-talkies, Bluetooth walkie-talkies are easy to be directly damaged due to wiring problems. The convenience of using Bluetooth for call installation and other aspects has gradually improved. There will also be some restrictions during the adoption process, and some minor faults will occur, especially in large In environments such as Internet cafes, the distance of the walkie-talkie is short, and the number of cables, transformers and other coil components carrying high currents is large, and the strength of the magnetic field generated is relatively high. The Bluetooth walkie-talkie is easily magnetized, and the signal receiving frequency is affected. Due to the interference of the magnetic field, the signal cannot be received or the signal is not received completely, resulting in informat...
