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.

A convertible head wearable audio device is provided that may include a headband having a first earpiece at a first end and a receptacle at a second end. The convertible head wearable audio device may also include a wireless interface. The wireless interface may be configured to communicatively couple the convertible head wearable audio device to a remote device. The convertible head wearable audio device may further include an active noise cancellation module. The active noise cancellation module may be configured to reduce ambient noise from an audio output of the convertible head wearable audio device.

The present disclosure generally relates to user interfaces for electronic audio devices. In some examples, the operating mode of the device changes to various states of sound transparency.

A wearable device including a body having one or more embedded electronic components, the body further including a thermoset material having a polymeric backbone with at least one urethane linkage and a glass transition temperature. At a first temperature that is lower than the glass transition temperature, the body has an original shape. When the body is heated to a second temperature that is higher than the glass transition temperature, the body is deformable from the original shape to a first shape and when the body is cooled to a third temperature that is lower than the glass transition temperature, the first shape is maintained. The body is further configured to transition from the first shape to the original shape when the body is heated from the third temperature to a fourth temperature that is higher than the glass transition temperature.

The present disclosure provides a loudspeaker device. The loudspeaker device includes a support connector configured to be in contact with a head and at least one speaker component. The at least one speaker component may include an earphone core and a core housing for accommodating the earphone core. The core housing may be fixedly connected to the support connector. The core housing may be provided with at least one key module. The support connector may accommodate a control circuit or a battery. The control circuit or the battery may drive the earphone core to vibrate to produce sound. The loudspeaker device of the present disclosure may optimize sound transmission efficiency and increase volume, th ereby improving the user experience.

A method for in-ear detection, the method may include transmitting test signals, by a speaker of an earbud, during a test period, and while the earbud is operating at a first operational mode, wherein the test signals comprise at least one first test signal within a first frequency range, at least one second test signal within a second frequency range, and at one third test signal within a third frequency range; wherein the first frequency range, the second frequency range and the third frequency range differ from each other and are within a human auditory range; generating, by a feedback microphone of the earbud, sensed information that is indicative of audio signals sensed by the feedback microphone as a result of the transmitting of the test signals; and determining whether the earbud is located within an ear of a person, wherein the determining is based on the sensed information and a reference out of ear spectrum.

Various implementations include wearable audio devices with counter-bore port features for maintaining a cover on the port. In certain cases, the wearable audio device includes a port that is integrated into the device frame and acoustically couples one or more acoustic cavities to a distinct volume. The device frame has a counter-bore feature proximate to the port for positioning a metal mesh.

A wireless communication device that is capable of being fixed to a decorative piece, including a housing body comprising a first shell piece and a second piece, wherein the first shell piece and the second shell piece, when coupled together, define a first space volume, a second space volume, and a pathway connecting the first space volume and the second space volume, a speaker circuit arranged in the first space volume, an electronic circuit arranged in the second space volume, wherein the electronic circuit is electrically connected to the speaker circuit, and an activation circuit electrically connected to the electronic circuit, wherein an activation of the activation circuit operatively connects the speaker circuit with the electronic circuit.

The present disclosure provides an audio playback system adapted to automatically switch an active microphone back and forth between two or more devices. For example, where the system is a pair of earbuds, where each earbud is worn by a separate user, the system may switch the active microphone to the device worn by the user that is speaking at a given time. While that device holds the active microphone, the other device may wait until a particular event that frees up the microphone, such as if the user wearing the device with the active microphone stops talking. According to some examples, a notification may be provided through one or more of the devices in the system to let the user know, for example, that he does not have the active microphone, that the active microphone is free, that the active microphone has been switched, etc.

The present disclosure provides a loudspeaker device. The loudspeaker device includes a support connector configured to be in contact with a head and at least one speaker component. The at least one speaker component may include an earphone core and a core housing for accommodating the earphone core. The core housing may be fixedly connected to the support connector. The core housing may be provided with at least one key module. The support connector may accommodate a control circuit or a battery. The control circuit or the battery may drive the earphone core to vibrate to produce sound. The loudspeaker device of the present disclosure may optimize sound transmission efficiency and increase volume, thereby improving the user experience.
