Embodiments of this application disclose a wind noise suppression device including a first woven mesh, a second woven mesh, a device housing, and a structural component. The device housing defines a sound pickup hole. The first woven mesh covers the sound pickup hole. The structural component is disposed behind the sound pickup hole. The structural component is coupled to the device housing and forms a cavity. The structural component defines a sound transmission hole. The second woven mesh covers the sound transmission hole. A microphone is disposed at the sound transmission hole. Due to the structural characteristics of all the components the device, wind noise included in an audio signal that is be received by the microphone through the sound transmission hole is effectively reduced.

Wind noise suppression device and design method

An active noise cancellation (ANC) method applied to a headset includes obtaining a first group of filtering parameters, and performing noise cancellation using the first group of filtering parameters. The first group of filtering parameters is one of Ngroups of filtering parameters prestored in the headset. The Ngroups of filtering parameters are respectively used to perform noise cancellation on ambient sound in Nleakage states. The Nleakage states are formed by the headset and Ndifferent ear canal environments. Nis a positive integer greater than or equal to two.

Active noise cancellation method and apparatus

A foldable cover plate is configured to be mounted to a tailstock of the movable device to cover or open an opening provided with the tailstock, and includes a plurality of cover assemblies rotationally connected in sequence. each of the plurality of cover assemblies includes a photovoltaic panel and a substrate. the photovoltaic panel of each of the plurality of cover assemblies is arranged on an associated substrate. The photovoltaic panel is configured to absorb light energy and convert the light energy to electrical energy. Any two adjacent cover assemblies of the plurality of cover assemblies are electrically connected to each other; and in a connection direction of the plurality of cover assemblies, a one-end cover assembly of the plurality of cover assemblies is configured to be electrically connected to an energy storage device arranged in the tailstock to charge the energy storage device.

Foldable cover plate and movable device

A foldable cover plate is configured to be mounted on a tail box of a mobile device, to cover an opening of the tail box. The foldable cover plate includes a cover plate assembly, a profile assembly, a connecting assembly, a waterproof assembly, and a locking assembly. The cover plate assembly includes three cover plates rotationally connected in sequence. The cover plate is rotationally folded over the remaining cover plates to expose the opening. The profile assembly is fixed to a periphery of the cover plate. The connecting assembly is connected to the profile assembly. The waterproof assembly is mounted to the profile assembly. The locking assembly is mounted to a face of the cover plate facing an interior of the tail box. The locking assembly is configured to fix the cover plate to the tail box. The foldable cover plate is easy to fold and has a stable structure.

This application discloses a method for reducing an occlusion effect of an earphone, and a related apparatus. The method is applied to an earphone having at least one microphone and a speaker. The method includes: detecting an occurrence of at least one of the following events: a user speaks and the user is in motion; and triggering at least one of the following operations in response to the at least one event: processing the user's sound signal based on the at least one microphone to suppress an occlusion effect of the earphone, and playing an audio by using the speaker, to mask a sound signal in the user's auditory canal. Embodiments of this application can reduce or even eliminate the earphone occlusion effect, to improve user experience.

Embodiments of this application disclose a noise cancellation apparatus and method. The noise cancellation apparatus includes a main control unit and a noise cancellation processing circuit. The main control unit determines a noise cancellation parameter based on a noise cancellation level index or a feature value for determining a matching degree between a headset and an ear canal of a user. The noise cancellation processing unit obtains an inverse phase noise of an ambient noise based on the noise cancellation parameter. After the inverse phase noise is mixed with a played downlink audio signal, the ambient noise can be canceled. In addition, because the noise cancellation parameter is determined from a preset noise cancellation parameter library based on the received or autonomously determined noise cancellation level index, instead of being uniformly configured, a noise cancellation level can be flexibly adjusted, thereby improving a noise cancellation effect and user experience.

Noise cancellation apparatus and method

A method for adjusting a touch screen, a touch chip, and an electronic terminal are provided. The method for adjusting a touch screen includes: receiving a characteristic signal corresponding to a usage scenario type of a terminal device that includes the touch screen; acquiring a touch screen adjustment parameter corresponding to the characteristic signal, where the touch screen adjustment parameter includes: at least one of a chip simulation parameter for controlling a touch chip of the touch screen and a firmware algorithm parameter; and adjusting an operating state of the touch screen based on the touch screen adjustment parameter. Through the embodiments of the present disclosure, a user can get excellent experience when using the touch screen in various usage scenarios.
