A communication method between earphones and a charging box is disclosed. The method comprises: acquiring a data packet to be sent from a sending queue; sending a data request message containing the data packet to be sent to the earphones; and when having received a reply message from the earphones, continuing to execute the step of acquiring a data packet to be sent from the sending queue until the sending queue is empty. In the communication method between earphones and a charging box of the present disclosure, when data is transmitted between the charging box and the earphones, the data transmission between the charging box and the earphones can be realized without switching the master-slave relationship between the charging box and the earphones, which is simple to realize and reduces the additional communication burden.

An open audio device includes an acoustic module and a body that supports the acoustic module. The acoustic module is configured to be located at least in part on the outer ear and defines a first sound-emitting opening that is configured to be proximate but spaced from the user's ear canal. The body includes a housing and a bridge that couples the acoustic module to the housing. The housing is configured to be located behind an outer ear of a user and in contact with at least one of the outer ear and the head proximate the intersection of the head and the outer ear. The bridge is constructed to have bending compliance.

Disclosed is a headset for playing audio and charging an external electronic device. The headset includes a first earpiece including a first inner speaker and a first outer speaker, a second earpiece including a second inner speaker and a second outer speaker, a selector operable to select play modes, the play modes including a first play mode and a second play mode, the first play mode being configured to play audio via the inner speakers, the second play mode being configured to play audio via the outer speakers, and a chargeable power bank being configured to provide power through a power output jack. One or more of the speakers may include a chargeable power bank for providing power to an external device and/or a wireless communicator for receiving audio signals. One or more of the speakers may be detachably securable to a headband.

An electronic apparatus according to an embodiment may comprise: a housing including a first housing having a first surface facing a first direction and a second housing having a second surface facing a second direction opposite to the first direction; a first audio port having a sound hole formed in the first surface of the housing; a speaker arranged in the housing and configured to output the sound to the outside via the sound hole of the first audio port; and a first recess formed by extending from the first audio port, wherein the first recess extends from the first audio port by a first length to have a first depth and a first width and is configured to form a passage through which the sound output from the speaker moves while the electronic apparatus is worn.

A charging contact assembly for a hearing device system. The assembly has a first charging contact which is accessible on an outer side for contacting with a first mating contact of a mating contact assembly, and a second charging contact which is accessible on the outer side for contacting with a second mating contact of the mating contact assembly. Furthermore, the charging contact assembly has a control contact which is galvanically isolated on the outer side from the first and the second charging contacts, and a charging controller which is configured to detect a proper contacting of the first and second charging contacts with the corresponding mating contact based on contact with the control contact.

The present application provides a wireless headphone assembly, which includes: a wireless headphone including a left earphone and a right earphone; an adaptor including a plug and a wireless communication module that are electrically connected to each other; the plug is configured for plugging into an interface of the an electronic device, such that the electronic device is in wireless communication with the wireless headphone through the wireless communication module; and a rechargeable earphone box including a box body and a box cover; the box body is provided therein wherein a left earphone receiving groove and a right earphone receiving groove, and the rechargeable earphone box is further provided with an adaptor receiving groove. The wireless headphone assembly provided by the present application can receive the adaptor, such that the adaptor is not easy to lose, and it is convenient for users to use.

A storage system includes a protective housing member configured to mate with a handheld electronic device. The protective housing member includes a charging area formed between a surface of the protective housing member and a surface of an accessory item of the handheld electronic device. The charging area is configured to charge the accessory item of the handheld electronic device. The charging area is powered by at last one power component of the protective housing member or at least one power component of the handheld electronic device. The storage system further includes at least one integrated circuit which is either a component of the handheld electronic device or a component of the protective housing member.

A control circuit for an electrostatic transducer including: an audio signal input, a detector configured to detect a current or charge signal from the electrostatic transducer. The detector is configured to produce an audio output signal varying at audio frequencies. A transform circuit is configured to transform the audio output signal to produce a feedback signal. A comparator is configured to compare an input audio signal at the audio signal input to the feedback signal to produce an error signal. A controller is configured to input a control signal to the electrostatic transducer, the control signal responsive to the error signal. The control signal is configured to control acoustic transparency of the electrostatic transducer, from outside space through through-holes of the first electrode, across the membrane and through through-holes of the second electrode.
