The top surface of the box body is provided with an electronic cigarette accommodation groove, a left earphone accommodation groove and a right earphone accommodation groove. The electronic cigarette, the left earphone and the right earphone all are capable of being inserted into the electronic cigarette accommodation groove, the left earphone accommodation groove and the right earphone accommodation groove along the direction perpendicular to the top surface of the box body, respectively.

Techniques for wirelessly charging a portable device are described. Charging circuits are designed based on energy efficiency that a charging voltage increases when the voltage of a battery being charged increases. In the case of charging a wireless earphone, the voltage output from a charging case changes in real time in accordance with the voltage on the battery in the earphone so as to reduce the energy consumption and improve the energy efficiency.

The present disclosure discloses a loudspeaker apparatus. The loudspeaker apparatus may include an ear hook, a core housing, and a circuit housing. The ear hook may include a first plug end and a second plug end. The ear hook may be surrounded by a protective sleeve. The protective sleeve may be made of an elastic waterproof material. The core housing may be used for accommodating an earphone core. The core housing may be fixed to the first plug end and elastically abutted against the protective sleeve. The circuit housing may be used for accommodating a control circuit or a battery. The circuit housing may be fixed to the second plug end. The control circuit or the battery may drive the earphone core to vibrate. The vibration of the earphone core may generate a driving force to drive a housing panel of the core housing to vibrate. The driving force may be not parallel to a normal line of the housing panel. In the present disclosure, the core housing may elastically abut against the protective sleeve surrounding the ear hook to improve the overall waterproof effect of the loudspeaker apparatus and simplify the manufacturing and assemble process of the loudspeaker apparatus.

A multimodal audio broadcast assembly for selectively enabling individual and group listening includes a pair of earbuds and a docking station. Each earbud is selectively engageable a respective ear of a user so that the earbud is removably engaged to the respective ear. The earbuds can receive wirelessly an audio signal from an electronic device and can broadcast the audio signal into the ears of the user. The docking station operationally engages the pair of earbuds so that the docking station is positioned to charge the pair of earbuds. The docking station also can receive the audio signal from the electronic device. A dock speaker is engaged to the docking station and is positioned to selectively broadcast the audio signal.

A wireless power system includes a wireless power transmitting device such as a wireless charging mat for charging devices such as a cellular telephone and an earbuds battery case. The earbuds battery case receives earbuds and charges the earbuds from a battery. The wireless charging mat supports bidirectional in-band communications between the cellular telephone and the earbuds battery case. The earbuds battery case provides the cellular telephone with information on the battery charge level associated with the battery in the earbuds battery case and a battery charge level associated with each earbud in the earbuds battery case. The cellular telephone receives battery charge level information through the wireless charging mat and displays corresponding indicators. The earbuds battery case has a visual output device such as a light-emitting diode that is illuminated to indicate that the earbuds battery case is being charged.

Audio systems and methods for obtaining location information are disclosed. A portable, wireless speaker may include a beacon that a user may activate to remotely trigger a request for shot information, which may include location information of the user or speaker. The beacon may be wirelessly coupled to the speaker. Notably, the beacon may comprise an earpiece such as an earbud or pair of earbuds. The speaker may receive location information from a remote device, such as a GPS-enabled mobile phone. The shot information may be converted into an audio format for playback by the speaker. The speaker may pause the playback of the speaker to play out the shot information. The system may also comprise a visual display.

Various aspects include wearable audio devices and related systems. In particular implementations, a wearable audio device includes: a base having: an acoustic transducer; a controller coupled with the acoustic transducer; and terminals for connecting a power source; and a first cap including: an antenna; and a battery including terminals for connecting with the terminals in the base, where the first cap is removably coupled to the base.

A rotating mechanism and a housing case are provided. The rotating mechanism includes a connection panel, a mounting base, and a rotating shaft. The connection panel has a first position and a second position. The mounting base includes a base body and protruding portions extending out of either side of the base body. The base body has a second notch. The second notch is arranged between the two protruding portions. Each protruding portion forms an accommodation slot opened toward the outer side of the base body. When the connection panel is in the first position, a portion of the connection panel is in the inner side of the base body, and when the connection panel is in the second notch, the portion of the connecting panel is arranged in the notch and closes the notch.

An earphone housing includes an inserter to be inserted into an outer ear hole, and a main body to be coupled to the inserter. The main body includes a bottom surface to contact a surface of a cavum concha, and a side surface to contact a tragus and an antitragus. The side surface includes a depressed part depressed inward and contacting a top of the antitragus, and the side surface contacts the tragus at a part other than the depressed part.

The present invention relates to the technical field of charging wireless earphones, in particular to a wireless earphone charging case convenient for replacing outer shells. Its outer shell has an upper shell and a lower shell that are capable of being disengaged/engaged from/with each other, wherein a containing space is arranged inside the lower shell, a charging chamber is arranged within the containing space, a screw slot is arranged on bottom of the charging chamber, the bottom of the lower shell is fixed to the screw slot on the bottom of the charging chamber by means of a metal screw.
