Abstract

A vibration sensor and a microphone are provided. The vibration sensor includes a piezoelectric system and a capacitive system. The piezoelectric system includes a vibration component and a piezoelectric sensing component collecting a first electrical signal generated due to deformation of the vibration component. The capacitive system uses the vibration component in the piezoelectric system as a movable capacitive plate and a fixed substrate opposite to the vibration component to form a capacitive vibration sensor. The deformation of the vibration component changes a distance between the vibration component and the fixed substrate. A capacitive sensing component collects a second electrical signal generated due to the distance change. The capacitive sensing component is disposed in a region where the first electrical signal in the piezoelectric system is low, thereby better using space of the vibration sensor, and enhancing the second electrical signal without affecting output of the first electrical signal.

Abstract

A speaker comprises a housing, a transducer residing inside the housing, and at least one sound guiding hole located on the housing. The transducer generates vibrations. The vibrations produce a sound wave inside the housing and cause a leaked sound wave spreading outside the housing from a portion of the housing. The at least one sound guiding hole guides the sound wave inside the housing through the at least one sound guiding hole to an outside of the housing. The guided sound wave interferes with the leaked sound wave in a target region. The interference at a specific frequency relates to a distance between the at least one sound guiding hole and the portion of the housing.

Abstract

In an audio denoising method and system provided in the present disclosure, a gain coefficient corresponding to each frequency unit may be generated based on a parameter related to a frequency by using a frequency of an audio signal as a unit, and gain processing is performed on each frequency unit separately by using the gain coefficient. The gain coefficient corresponding to a frequency unit including more valid audio signals may be larger, and a gain coefficient corresponding to a frequency unit including fewer valid audio signals may be smaller, so that more audio signals corresponding to frequency parts including more valid audio signals are preserved, while less audio signals corresponding to frequency parts including fewer valid audio signals are preserved. In this way, fidelity and intelligibility of an audio signal are improved while quality of the audio signal is improved and noise is reduced.

Abstract

A speaker comprises a housing, a transducer residing inside the housing, and at least one sound guiding hole located on the housing. The transducer generates vibrations. The vibrations produce a sound wave inside the housing and cause a leaked sound wave spreading outside the housing from a portion of the housing. The at least one sound guiding hole guides the sound wave inside the housing through the at least one sound guiding hole to an outside of the housing. The guided sound wave interferes with the leaked sound wave in a target region. The interference at a specific frequency relates to a distance between the at least one sound guiding hole and the portion of the housing.

Abstract

The present description provides a voice activity detection method and system, a voice enhancement method and system. A microphone signal output by a microphone array satisfies a first model corresponding to a noise signal or a second model corresponding to mixing of a target voice signal and the noise signal. The methods and systems can optimize the first model and the second model by maximizing a likelihood function and minimizing a rank of a noise covariance matrix, and determine a first estimated value of a noise covariance matrix of the first model and a second estimated value of a noise covariance matrix of the second model, and decide whether the microphone signal satisfies the first model or the second model by means of a statistical hypothesis testing method, thereby determining whether a target voice signal is present in the microphone signal, as well as determine a noise covariance matrix of the microphone signal, and then perform voice enhancement on the microphone signal. The present methods and systems can improve noise covariance estimation precision, thereby improving a voice enhancement effect.

Abstract

The present description provides a speech presence probability calculating method and system, a speech enhancement method and system, and headphones. By comparing entropy of a speech presence probability and entropy of a speech absence probability, the speech presence probability and the speech absence probability in an iteration process are corrected to obtain a higher convergence speed and a better convergence result. Thus, the speech presence probability and noise covariance matrix estimation accuracy is higher, thereby improving the speech enhancement effect of MVDR.

Abstract

A speaker comprises a housing, a transducer residing inside the housing, and at least one sound guiding hole located on the housing. The transducer generates vibrations. The vibrations produce a sound wave inside the housing and cause a leaked sound wave spreading outside the housing from a portion of the housing. The at least one sound guiding hole guides the sound wave inside the housing through the at least one sound guiding hole to an outside of the housing. The guided sound wave interferes with the leaked sound wave in a target region. The interference at a specific frequency relates to a distance between the at least one sound guiding hole and the portion of the housing.
