Multifunctional Bluetooth earphone with adjusting device

Abstract

The invention discloses a multifunctional Bluetooth earphone with an adjusting device, which comprises a Bluetooth earphone body, two groups of receivers are symmetrically arranged on the Bluetooth earphone body, and a plurality of groups of circumferentially arranged movable parts are arranged in cavities of the two groups of receivers; a driving ring is rotationally clamped on the outer wall of the receiver, and the driving ring is engaged with the input ends, located on the inner cavity wall of the receiver, of the plurality of groups of moving parts. According to the multifunctional Bluetooth earphone with the adjusting device, the driving ring and the movable part are arranged, a threaded rod can be driven to rotate through rotation, a movable plate can be driven to do linear motion through a threaded pipe, the inner diameter of a listening cavity of a receiver can be changed to adapt to the requirements of different ear sizes, a limiting sliding block is installed at the lower end of the movable plate. The movable plate can be driven by the threaded pipe to do stable linear motion, the elastic buffering cushion is fixed to the outer wall of the movable plate, the pressure between the movable plate and the ear can be buffered through the elastic buffering cushion, and the use comfort of the ear cushion is improved.

Description

technical field [0001] The invention relates to the field of bluetooth earphones, in particular to a multifunctional bluetooth earphone with an adjusting device. Background technique [0002] Bluetooth headset is a small device based on Bluetooth technology. You only need to hide this lightweight device by the headset without directly using communication devices (mobile phones, computers, etc.) to achieve free calls. Bluetooth headsets are Bluetooth The technology is applied to hands-free headsets, allowing users to talk freely in various ways without being entangled by annoying wires. Since the advent of Bluetooth headsets, it has been a good tool for mobile business families to improve efficiency. Bluetooth is a low-cost, high-capacity short-distance wireless communication specification. Ericsson first proposed the concept of Bluetooth in 1995. The Bluetooth specification works in the microwave frequency band, with a transmission rate of 1M bytes per second and a maximum ...

AI Technical Summary

Problems solved by technology

[0003] Bluetooth headsets are derived from existing headsets into in-ear Bluetooth headsets and head-mounted blue night headsets. In order to ensure sound quality and call quality, the noise reduction function is applied to each Bluetooth headset. The earpiece of the existing headset Bluetooth headset The inner diameter cannot be adjusted according to the size of the human ear, which is not conducive to the fact that ears of different sizes can completely enter the hearing cavity of the earpiece, which reduces its comfort and limits its scope of use, and does not take advantage of the wide application of Bluetooth earphones. Therefore, we Propose a multifunctional bluetooth earphone with adjustment device to solve this problem
