Abstract: The present invention relates to a bone conduction speaker and its compound vibration device. The compound vibration device comprises a vibration conductive plate and a vibration board, the vibration conductive plate is set to be the first torus, where at least two first rods inside it converge to its center; the vibration board is set as the second torus, where at least two second rods inside it converge to its center. The vibration conductive plate is fixed with the vibration board; the first torus is fixed on a magnetic system, and the second torus comprises a fixed voice coil, which is driven by the magnetic system. The bone conduction speaker in the present invention and its compound vibration device adopt the fixed vibration conductive plate and vibration board, making the technique simpler with a lower cost; because the two adjustable parts in the compound vibration device can adjust both low frequency and high frequency area, the frequency response obtained is flatter and the sound is broader.

Abstract: An audio generation method and system provided in this disclosure can dynamically select a frequency splicing point of an audio signal based on voice quality of a first audio signal and a second audio signal corresponding to each frequency in a frequency domain, divide the frequency domain into a first frequency interval and a second frequency interval, select audio signals of higher voice quality that correspond to each frequency interval for splicing, and obtain a target audio signal after fusion of the first audio signal and the second audio signal, so that voice quality of the target audio signal in each frequency interval in the frequency domain is the best, thereby improving voice quality of the target audio signal after fusion.

Abstract: In an audio signal processing method and system for echo suppression, selection of a target audio processing mode is controlled based on strength of a speaker signal. In the method and system, a control signal is generated based on the strength of the speaker signal, and the target audio processing mode is controlled based on the control signal to perform signal processing on a microphone signal so as to obtain better voice quality. When the speaker signal does not exceed a threshold, the system selects a first mode, and performs signal processing on a first audio signal and a second audio signal to obtain a first target audio; or when the speaker signal exceeds a threshold, the system selects a second mode, and performs signal processing on a second audio signal to obtain a second target audio, and the mode can be switched based on the speaker 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: A bone conduction speaker is provided herein. The bone conduction speaker may include a magnetic circuit component for providing a magnetic field, a vibration component located in the magnetic field, and a case. At least a part of the vibration component may convert an electrical signal into a mechanical vibration signal.
