The present disclosure relates to an apparatus. The apparatus may comprise two ear-hook assemblies configured to be hung outside of two ears of a user respectively, and a rear-hook assembly in a curved shape configured to connect the two ear-hook assemblies and wrap around a rear side of the head of the user. The rear-hook assembly may include an elastic metal filament, wires, and an elastic covering body covering the elastic metal filament and the wires.

An electronic device is provided. The electronic device includes a housing including a microphone hole, a support member connected to the housing, wherein the support member includes an antenna structure facing at least a part of the housing and a microphone chamber configured to receive external sound of the electronic device from the microphone hole, and a microphone module connected to the support member and configured to receive external sound of the electronic device through the microphone hole and the microphone chamber.

Implementations of the subject matter described herein provide a silent voice input solution without being noticed by surroundings. Compared with conventional voice input solutions which are based on normal speech or whispering, the proposed “silent” voice input method is performed by using ingressive voice during the user's breathing-in process. By placing the apparatus very close to the user's mouth with a ultra-small gap formed between the microphone and the apparatus, the proposed silent voice input solution can realize a very small voice leakage, and thereby allowing the user to use ultra-low voice speech input in public and mobile situations, without disturbing surrounding people.

An earphone device and system for improving wind resistance protection as well as controllability of true wireless stereo (TWS) headsets are provided. The earphone device includes headset microphones in a housing facing outwards and configured to generate a microphone signal. The earphone device includes a control dial rotatably attached to the housing through a pivot. The dial is substantially flat and arranged to form a narrow gap between the housing and the dial. The dial is further arranged to cover each microphone, thereby providing wind and dirt protection but leaving a gap for the sound waves to reach the microphones.

This present disclosure provides an acoustic device. The acoustic device includes a housing, one or more sound pickup assemblies, and one or more channel assemblies. The housing has an accommodating space and one or more communication holes. Each communication hole communicates the accommodating space and an outside space. The one or more sound pickup assemblies may be disposed in the accommodating space for picking up a sound through the communication holes. The one or more channel assemblies may be disposed in the accommodating space. At least one of the one or more channel assemblies is disposed between one sound pickup assembly of the one or more pickup assemblies and one communication hole of the one or more communication holes, so that the sound is transmitted to the sound pickup assembly through the at least one of the one or more channel assemblies after passing through the communication hole.

An audio capture device selects between multiple microphones to generate an output audio signal depending on detected conditions. The audio capture device determines whether one or more microphones are wet or dry and selects one or more audio signals from the one or more microphones depending on their respective conditions. The audio capture device generates a mono audio output signal or a stereo output signal depending on the respective conditions of the one or more microphones.

An earphone includes a housing and a microphone. The microphone is provided in the housing. The housing includes a hole that leads to the microphone. The hole has a shape in which a cross-sectional area expands, toward a back of a head of a user wearing the earphone, from the microphone toward an outside of the housing. The housing, in a case of being worn by the user, is located farther away from an external earhole, in an outside direction from a side of the head, than from an ear of the user.

A method of suppressing wind noise of a microphone and/or an electronic device are disclosed. The method of suppressing wind noise of a microphone includes receiving an audio signal, obtaining a frequency spectrum of the audio signal and a power spectrum of the audio signal, determining a wind noise power spectrum of the audio signal based on the power spectrum, determining a wind noise suppression gain based on the wind noise power spectrum and the power spectrum, correcting the frequency spectrum according to the determined wind noise suppression gain, and converting the corrected frequency spectrum into a time domain to obtain a corrected audio signal.

Systems and methods for enhancing a headset user's own voice include at least two outside microphones, an inside microphone, audio input components operable to receive and process the microphone signals, a voice activity detector operable to detect speech presence and absence in the received and/or processed signals, and a cross-over module configured to generate an enhanced voice signal. The audio processing components includes a low frequency branch comprising low pass filter banks, a low frequency spatial filter, a low frequency spectral filter and an equalizer, and a high frequency branch comprising highpass filter banks, a high frequency spatial filter, and a high frequency spectral filter.

A virtual image display includes acoustic sensors and a controller, and a method is for operating the same. The acoustic sensors are for detecting the wind frequency information in the environment. The controller computes time points of the acoustic sensors receiving the wind frequency information, and computes wind direction information based on the time points.
