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.

Acoustic devices

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.

Acoustic output devices

The present disclosure discloses a loudspeaker apparatus. The loudspeaker apparatus may include a support connection member configured to contact with a user's head. The loudspeaker apparatus may include at least one loudspeaker assembly. The loudspeaker assembly may include an earphone core and a core housing configured to accommodate the earphone core. The core housing may be fixedly connected to the support connection member. At least one button module may be arranged on the core housing. The interior of the core housing may further include at least two microphones, and the at least two microphones may be arranged at a position different from a user's mouth. The loudspeaker apparatus may further include a control circuit or a battery accommodated in the support connection member. The control circuit or the battery may drive the earphone core to vibrate to generate sound.

Loudspeaker apparatus

The present disclosure provides an acoustic output apparatus. The acoustic output apparatus may include a bone-conduction acoustic assembly, an air-conduction acoustic assembly, and a housing. The bone-conduction acoustic assembly may be configured to generate bone-conduction sound waves. The air-conduction acoustic assembly may be configured to generate air-conduction sound waves. The housing may include an accommodating chamber configured to accommodate the bone-conduction acoustic assembly and the air-conduction acoustic assembly. At least a portion of the housing may be in contact with a user's skin to transmit the bone-conduction sound waves under an action of the bone-conduction acoustic assembly. The air-conduction sound waves may be generated based on vibrations of at least one of the housing or the bone-conduction acoustic assembly when the bone-conduction sound waves are generated.

Acoustic output apparatus

The present disclosure provides a system and method for acoustic device. The acoustic output device may include an earphone core including at least one acoustic driver for outputting sound though one or more sound guiding holes set on the acoustic output apparatus; the acoustic output device may include one or more sensors configured to detect status information of a user of the acoustic output apparatus; the acoustic output device may include a controller configured to cause the at least one acoustic driver to output sound based on the detected status information of the user; the acoustic output device may further include a power source assembly configured to provide electrical power to the earphone core, the one or more sensors, and the controller; and the acoustic output device may further include a flexible circuit board configured to connect at least the earphone core and the power source assembly.

Acoustic output apparatus with multiple sound guide holes and bluetooth low energy reciever

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 an open earphone comprising: a sound production component including a transducer and a housing accommodating the transducer and an ear hook. In a wearing state, a portion of the ear hook is hung between an auricle and a user's head, and the other portion of the ear hook extends towards a side of the auricle away from the head and connects to the sound production component to place the sound production component in a position near an ear canal but not blocking the ear canal. The housing is provided with a sound outlet on an inner side surface towards the auricle for guiding a sound generated by the transducer out of the housing and to the ear canal, and a ratio of an area of the sound outlet to an area of the inner side surface is between 0.015 and 0.25.
