    Abstract: The present disclosure provides an acoustic output device including a speaker assembly. The speaker assembly may include a transducer, a diaphragm, and a housing. A vibration of the diaphragm driven by the transducer may generate an air conduction sound wave. The housing may form an accommodating chamber for accommodating the transducer and the diaphragm. The diaphragm may separate the accommodating chamber to form a first chamber and a second chamber. A sound outlet communicating with the second chamber is arranged on the housing. The air conduction sound wave is transmitted to the outside of the acoustic output device through the sound outlet. A sound guiding channel communicating with the sound outlet is provided on the housing for guiding the air conduction sound wave to a target direction outside the acoustic output device. The length of the sound guiding channel may be less than or equal to 7 mm.

    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: The present disclosure provides an acoustic device. The acoustic device may include a housing, a transducer, and a diaphragm. The housing may be configured to form a cavity. The transducer may be arranged in the cavity and connected to the housing. The housing may produce a bone-conduction sound under an action of the transducer. The diaphragm may be connected between the transducer and the housing to divide the cavity into a first cavity and a second cavity. The housing may be provided with at least one pressure relief hole communicating with the first cavity and at least one sound modulation hole communicating with the second cavity. At least a portion of the at least one pressure relief hole and at least a portion of the at least one sound modulation hole may be arranged adjacently. The housing may be further provided with a sound outlet hole communicating with the second cavity. The diaphragm may produce an air-conduction sound transmitted outward through the sound outlet hole during a relative movement of the transducer and the housing.

    Abstract: The embodiments of the present disclosure are for a signal processing circuit. The signal processing circuit includes an analog circuit. The analog circuit is used for processing an initial signal it receives. The initial signal includes a target signal and a noise signal. The analog circuit includes a first processing circuit and a second processing circuit. The first processing circuit is used to increase a ratio of the target signal to the noise signal, and output a first processed signal. The second processing circuit is used to amplify the first processed signal. A gain multiple of the second processing circuit to the first processed signal varies with a frequency of the first processed signal. The first processing circuit includes a common mode signal suppression circuit used to suppress a common mode signal in the initial signal, a lowpass filter circuit, and a high-pass filter circuit.
