5results about How to "Improve call quality" patented technology

The utility model provides an earphone and an earphone assembly. The earphone comprises a shell, a sound production unit and a sound reception unit. A sound inlet is arranged in the housing. The sound production unit and the sound reception unit are arranged in the housing. The sounding unit is arranged on one side, close to the auricular conchae, of the sound receiving unit. The sounding unit is electrically connected with the radio unit. A first pickup hole, a pickup channel and a second pickup hole which are integrally formed through injection molding are formed in the shell. The first pickup hole and the second pickup hole are arranged on two opposite sides of the shell along the first direction and are used for communicating with the external environment. The pickup channel is communicated with the first pickup hole and the second pickup hole along the first direction. The sound inlet is arranged on one side of the pickup channel along the second direction and is used for communicating the pickup channel with the sound receiving unit. The pickup channel is isolated from the sounding unit. Wherein the first direction intersects with the second direction. According to the earphone provided by the embodiment of the invention, the processing procedure after the shell is formed can be omitted, and the production cost of processing and manufacturing is reduced.

The utility model discloses an earphone, and belongs to the technical field of earphones. The earphone comprises a shell, a pickup assembly and a wind shielding piece, the shell is provided with a containing cavity and a pickup hole, the containing cavity is communicated with the pickup hole, the pickup assembly is arranged in the containing cavity, the wind shielding piece is arranged in the containing cavity and located on the side, close to the pickup hole, of the pickup assembly, and the surface of the side, close to the pickup hole, of the wind shielding piece is a concave surface. And the opening direction of the concave surface faces the pickup hole, so that the concave surface can change the direction of air flow entering the accommodating cavity through the pickup hole. The earphone can reduce wind noise.

This utility model discloses a Bluetooth microphone for use inside a breathing mask, relating to the field of Bluetooth microphone technology. The utility model includes a main body, and a microphone and a control unit disposed at both ends of the lower part of the main body. The microphone and control units are electrically connected to the inside of the main body via a plug-in connection. The outer shell of the microphone is evenly provided with microphone slots, and an integrated circuit board is built into the outside of the microphone. A microphone unit is configured on the integrated circuit board, and the microphone unit is connected to a Bluetooth module via PCB traces. A power supply unit is integrated inside the control unit, and the power supply unit is connected to the microphone through internal wires in the main body. This utility model integrates the microphone and control units into a U-shaped main body structure, resulting in a compact overall structure and convenient installation, facilitating use within the limited space inside a breathing mask. It also improves the modularity and maintainability of the device. The microphone unit, combined with a digital signal processing module, effectively suppresses environmental noise, significantly improving voice recognition and call quality.

The application relates to the field of mobile phone supports, in particular to a multipurpose mobile phone support which comprises a support base, the support base comprises a base, fixedly connected with fixed seats on both sides of the rear end of the base, rotatably connected with support arms through damping rods between the fixed seats, fixedly connected with a Bluetooth sound box on one side of the top of the support arms, slidably connected with telescopic arms in the support arms, rotatably connected with supporting mechanisms on the ends of the telescopic arms away from the support arms, provided with light supplementing mechanisms on both sides of the top of the base, connected with fixed mechanisms through reset mechanisms on the bottom of the rear side of the light supplementing mechanisms, and the fixed mechanisms are arranged on the bottom of the base. The fixed strip one can realize the compression and fixation of the binding belt, the support base can be converted between the flat laying and the fixation between the fixed points, the actual use is facilitated, and people can use the support on the car or when cooking.
