The invention relates to an interactive headphone system for storing and playing audio content comprising an NFC tag with an RFID code that contains a distinctive identification of the NFC tag, and headphones that comprise a memory that stores one or more audio files, where each of the one or more audio files is associated with a distinctive identification, where the one or more audio files are locked so that access is possible only with an RFID code containing a distinctive identification corresponding to the distinctive identification of a respective audio file, and an NFC reader, where, when the NFC tag having a distinctive identification corresponding to the distinctive identification of a respective audio file is brought into the immediate vicinity of the NFC reader, the headphones are configured to: process the RFID code containing the distinctive identification of the NFC tag; correlate the distinctive identification of the NFC tag with the distinctive identification of the audio file stored on the memory; unlock the audio file; and automatically start playback of the audio file.

A method for manufacturing a cartilage conduction audio device is disclosed. A manufacturing system receives data describing a three-dimensional shape of an ear (e.g., the outer ear, behind the ear, the concha bowel, etc.) of a user. The system identifies one or more locations for one or more transducers along a back of an auricle of the ear for the user that vibrate the auricle over a frequency range causing the auricle to create an acoustic pressure wave at an entrance of the ear canal. The system then generates a design for a cartilage conduction audio device for the user based on the one or more identified locations of the transducers at which acoustic pressure waves generated by the one or more transducers satisfy a threshold performance metric for the user. The design may then be used to fabricate the cartilage conduction audio device.

Stereo headphone and methods for content sharing and for authentication. The stereo headphone includes two earpieces each having a housing, at least one electronic circuit housed in the housing of at least one of the earpieces, configured to allow the headphone to be paired with a remote terminal such as a cellular telephone and to establish a wireless link therewith. The electronic circuit includes an internal memory with more than 32 GB of capacity, an audio player making it possible to play audio files, in particular those saved in this internal memory, and an interface making it possible to select, as the source to be broadcast in the earpieces, the audio player of the headphone or the paired terminal.

The present disclosure provides an acoustic output apparatus. The acoustic output apparatus may include an acoustic output component and a supporting structure forming an acoustically open structure that allows the acoustic output component to acoustically communicate with the surroundings. The acoustic output component may include a plurality of acoustic drivers, each of which may be configured to output a sound with a frequency range. At least one of the acoustic drivers may include a magnetic system for generating a first magnetic field. The magnetic system may include a first magnetic component for generating a second magnetic field and at least one second magnetic component. A magnetic gap may be formed between the first magnetic component and the at least one second magnetic component. A magnetic field intensity of the first magnetic field in the magnetic gap may be greater than that of the second magnetic field in the magnetic gap.

A method and system for a headset with internal gimbal, where the headset comprises a headband, a headband, and ear cups coupled to the headband, wherein each ear cup may be coupled to the headband utilizing an internal gimbal. The internal gimbal may comprise a tip that is wider than its base. The tip may be rounded. The headband may comprise headband endcaps at each end of the headband. A headband slide may be coupled to each headband endcap. The headband ear cups may be coupled to the headband via the headband slides. Each headband slide may be coupled to a headband endcap via a headband pivot. The headband pivot may provide rotational motion of the ear cups with respect to the headband. The force on ears of a user of the headset may be spread evenly by the internal gimbals.

Left and right earphones are independently wireless such that the left and right earphones are not physically connected when worn by a user. Each earphone comprises a speaker and a body portion with an SOC. Each SOC comprises a wireless communication circuit and a processor. Each speaker is for playing audio streamed to the earphones in a lossy compressed format.

The present disclosure relates to an open binaural earphone including a housing, at least one low-frequency speaker, and at least one high-frequency speaker. The housing may be placed on at least one of a head or an ear of a user and not blocking a user’s ear canal, and configured to accommodate the at least one low-frequency speaker and the at least one high-frequency speaker. The at least one low-frequency speaker may be configured to output sounds within a first frequency range from at least two first sound guiding holes through at least two first guiding tubes. The at least one high-frequency speaker may be configured to output sounds within a second frequency range from at least two second sound guiding holes through at least two second guiding tubes. The second frequency range may include one or more frequencies higher than one or more frequencies in the first frequency range.

A method for controlling headphones. The headphones include a feedback microphone and a speaker. The method includes: obtaining an ear canal audio signal by collecting an audio signal in an ear canal by the feedback microphone; obtaining an audio signal feature parameter by conducting feature extraction on the ear canal audio signal; determining a tightness level of the headphones in a current wearing status; generating an audio feature to be identified according to the audio signal feature parameter and the tightness level; inputting the audio feature to be identified into a preset interactive operation identification model, and outputting an identification result, where the identification result includes an interactive operation identifier; determining a control instruction corresponding to the interactive operation identifier; and controlling a playback status of the speaker according to the control instruction.
