The embodiments of the present disclosure provide an acoustic output device, including: a first piezoelectric element configured to generate vibrations based on an audio signal; a fixing structure configured to place the acoustic output device near a user's ear without blocking the user's ear canal, an end of the fixing structure being connected to one end of the first piezoelectric element; and a vibration transmission component including an ear hook and an output assembly, one end of the ear hook being connected to an end of the first piezoelectric element away from the fixing structure, the other end of the ear hook being connected to the output assembly, the output assembly receiving the vibrations of the first piezoelectric element through the ear hook and outputting sound, and a frequency response curve of the sound having at least two resonant peaks.

Acoustic output device and wearable device

The present disclosure provides an earphone comprising a sound production component and a suspension structure. The sound production component includes a diaphragm and a housing. In a wearing state, the suspension structure is used to place the sound production component at a position near but not blocking an ear canal, wherein an inner side surface of the housing facing an auricle is provided with a sound outlet, at least another side surface of the housing is provided with a first pressure relief hole, and a distance between a center of the sound outlet and a midpoint of an upper boundary of the inner side surface is greater than a distance between a center of the first pressure relief hole and the midpoint of the upper boundary of the inner side surface.

Earphones

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 wearable device, the wearable device comprising a deflector structure configured to be worn on a head of a user, wherein the deflector structure may include a first connecting section, a second connecting section, and a concave section. The first connecting section, the concave section, and the second connecting section may be connected in sequence. The concave section has a downward depression relative to the deflector structure. A first microphone may be configured to collect a sound signal, the first microphone may be located at the concave section.

Wearable devices

The present disclosure discloses a wearable device and a wearing member thereof. The wearing member includes: a housing including a concave section, the concave section forms a downward hollow in a wearing state, and the hollow includes a first sound pickup hole for an input of a sound; and a first sound pickup member disposed in the concave section and configured to pick up the sound input through the first sound pickup hole. In such cases, the wearing member provided by the present disclosure may improve the quality of a picked-up sound by reducing a wind noise interference, thereby improving the voice control efficiency of a user to the wearing member or call quality of the wearable device.

Wearable devices and wearing members thereof

The present disclosure relates to a device for processing an audio signal. The device may include a first acoustic-electric transducer and a second acoustic-electric transducer. The first acoustic-electric transducer may have a first frequency response, and may be configured to detect the audio signal and generate a first sub-band signal according to the detected audio signal. The second acoustic-electric transducer may have a second frequency response, the second frequency response being different from the first frequency response. The second acoustic-electric transducer may be configured to detect the audio signal and generate a second sub-band signal according to the detected audio signal.
