The embodiments of the present disclosure provide a signal processing circuit and a signal processing method. The signal processing circuit may include a control circuit, a switch circuit, an analog circuit, and at least two signal acquisition circuits. The at least two signal acquisition circuits may be configured to acquire at least two-channel target signals. The switch circuit may be configured to control conduction between the at least two signal acquisition circuits and the analog circuit, so that the target signal acquired by a part of the at least two signal acquisition circuits may be transmitted to the analog circuit at the same time. The analog circuit may be configured to process the received target signal. The control circuit may be configured to receive the processed target signal and sample the processed target signal.

Signal processing circuits and methods

A voice activity detection method and system and a voice enhancement method and system are provided. A voice presence probability of a target voice signal present in microphone signals may be determined by calculating a linear correlation between a signal subspace where the microphone signals are located and a target subspace where the target voice signal is located. The voice enhancement method and system may be used to calculate filter coefficients based on the voice presence probability, so as to perform voice enhancement on the microphone signals. The calculation accuracy of the voice presence probability is improved, and the voice enhancement effect is also improved.

Voice activity detection method and system, and voice enhancement method and system

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.

Systems and methods for suppressing sound leakage

The present disclosure provides a fixing assembly and a wearing device of a bone conduction vibrator, comprising: an elastic fixing portion, the elastic fixing portion being in a form of a band structure, the elastic fixing portion including a first position and a second position, the first position and the second position being disposed at intervals along a length direction of the elastic fixing portion; and a fixing member, configured to fix the elastic fixing portion around a wearing object, so that the bone conduction vibrator is located between the elastic fixing portion and the wearing object. When the elastic fixing portion surrounds the wearing object and is in a natural state, the fixing member fits into the first position of the elastic fixing portion; when the fixing member fits into the second position, the elastic fixing portion provides the bone conduction vibrator with a pressure acting on the wearing object, and the pressure is within a preset pressure range.

Fixing assemblies and wearing devices of bone conduction vibrators
