7results about How to "Improve call quality" patented technology

Disclosed are a noise reduction method for a microphone array of an earphone, an apparatus, an earphone, and a TWS earphone. The method comprising: acquiring, when a wearer of the earphone speaks, a first sound signal collected by a bone conduction microphone arranged on the earphone and second sound signals collected respectively by a preset number of microphones arranged on the earphone; determining, according to the first sound signal and the second sound signal, a delay time from a time when the voice signal arrives at each microphone to a time when the voice signal arrives at the bone conduction microphone; computing, according to the delay time, a pointing angle of the microphone array formed by the microphones relative to a mouth of the wearer; and adjusting a beam pointing angle of the microphone array according to the pointing angle, such that the microphone array forms a beam by means of an adjusted beam pointing angle. In the present disclosure, the bone conduction microphone is used to determine a time delay from reception of a voice signal by each microphone in the microphone array to that of the bone conduction microphone, thereby adaptively adjusting the beam pointing angle of the microphone array, ensuring a noise reduction effect of the microphone array, and improving user experience.

This disclosure provides a method, apparatus, device, medium, and program product for voice recovery. The method, applied to a receiving terminal, includes: receiving primary voice data from a transmitting terminal; receiving text information sent by the transmitting terminal, wherein the text information is generated by converting the sender's speech into text and sending it to the receiving terminal; obtaining secondary voice data based on the text information and pre-acquired user voiceprint information of the transmitting terminal; and supplementing the lost voice data packets of the primary voice data based on the secondary voice data to obtain reconstructed primary voice data. Since the packet loss rate of voice data is far greater than that of text information, and text information can contain all the information that the voice intends to express, the above method can supplement the lost voice data packets, complete the primary voice data heard by the receiving user, enable the receiving user to hear all the content spoken by the sender, improve call quality, and thus enhance the user's voice call experience.

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.
