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 embodiments of the present disclosure provide a sensor device, including: a sensor assembly with a first resonant frequency and a sound pickup assembly configured to communicate with an external sound of the sensor device through a sound inlet, wherein an acoustic cavity may be formed between the sound pickup assembly and the sensor assembly, when the sound pickup assembly vibrates in response to an air conduction sound transmitted through the sound inlet, vibrations of the sound pickup assembly may change a sound pressure in the acoustic cavity, and the sensor assembly may convert the air conduction sound into an electrical signal based on changes of the sound pressure in the acoustic cavity, wherein the sound pickup assembly may provide the sensor device with a second resonant frequency, and a difference between the second resonant frequency and the first resonant frequency may be in a range of 1000 Hz-10000 Hz.

Sensor device

The driving unit includes a plurality of driving beams, each of the plurality of driving beams includes a fixed region and an overhanging region. Each of the plurality of driving beams is connected with the casing through its fixed region, and each of the plurality of driving beams is connected with the vibration unit through its overhanging region.

Loudspeakers

A vibration sensor () is provided, comprising: a vibration receiver () including a housing () and a vibration unit (), the housing () forming an acoustic cavity, the vibration unit () being located in the acoustic cavity and separating the acoustic cavity into a first acoustic cavity () and a second acoustic cavity (); and an acoustic transducer () acoustically connected to the first acoustic cavity (). The housing () is configured to generate a vibration based on an external vibration signal, the vibration unit () changes an acoustic pressure within the first acoustic cavity () in response to the vibration of the housing (), causing the acoustic transducer () to generate an electrical signal. The vibration unit () includes a quality element () and an elastic element (), an area of the quality element () on a side away from the acoustic transducer () is smaller than an area of the quality element () on a side close to the acoustic transducer. The elastic element () is connected around a side wall of the quality element ().

Vibration sensors

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.

Audio denoising method and system

The present disclosure 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 disclosure 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.
