A wireless sound device set compatible with various devices. The wireless sound device set compatible with various devices may include: a wireless sound device; a charging case; a connection cable, a controller for automatically performing one selected from a charging mode and a relay mode; and a wireless communication module for receiving output sound information and transmitting same to the wireless sound device. An independent wireless connection causes no intervention from another external device, and thus maintain stable pairing.

The disclosed computer-implemented method may include (i) detecting a battery condition of a wearable battery-operated device that indicates a threat to a battery's health and (ii) in response to detecting the battery condition, performing a battery-protection action by initiating a reverse power flow across a bidirectional connection from the wearable battery-operated device to a portable charging case that is designed to charge the wearable battery-operated device. Various other methods, systems, and computer-readable media are also disclosed.

The disclosure herein provides a mobile system including a mobile base station and a wireless earbud. The base station comprising a connection hole, a user input button, at least one processor, at least one memory, and circuitry. The wireless earbud is configured for plugging into the connection hole of the base station to form an integrated body with the base station. The system establishes a wireless Bluetooth pairing between a smartphone and the wireless earbud using two-way wireless communication to produce Bluetooth communication between the smartphone and the wireless earbud.

The present disclosure discloses a loudspeaker apparatus. The loudspeaker apparatus may include a circuit housing, an ear hook, a rear hook, a loudspeaker component, and a magnetic connector. The circuit housing may be configured to accommodate a control circuit or a battery component. The ear hook may be connected to one end of the circuit housing and at least partially covered by a first protective housing. The rear hook connected to another end of the circuit housing and at least partially covered by a second protective housing. The magnetic connector may be configured to absorb a charging interface of an external power source to establish an electrical connection so as to charge the loudspeaker apparatus.

A wireless communication system comprises a first wireless communication device for a first team member, and a second wireless communication device for a second team member. The first wireless communication device comprises a microphone and a transmitter for transmitting an oral message via a first wireless communication protocol. The second wireless communication device comprises a main transceiver, a wearable audio device, and a support configured for mounting the main transceiver onto hockey shoulder pads of the second team member in a location physically remote from the wearable audio device.

A self-auscultation device and method of using the self-auscultation device to listen to a target anatomy is described. The self-auscultation device includes a chest piece to receive a listening device, such as an earphone. The listening device is mounted in the chest piece to detect a sound from the target anatomy, through the chest piece. The listening device can operate in a self-auscultation mode to adapt the listening device to generate audio data corresponding to the detected sound. An equalization filter can be applied to the audio data to compensate for a frequency response of the listening device. A data processing system can compare the audio data to predetermined auscultation data to determine a health condition of the target anatomy. Other embodiments are also described and claimed.

A wireless charger inductively charges devices of various shapes and/or types, such as with multiple bend radii. Smartphones, headphones, key fobs, and other wireless devices may be laid atop the wireless charger. The wireless charger has flexible and pliable features that conform to the shape of the wireless device. The flexible and pliable features maintain a conformal relationship with the wireless device laid atop the wireless charger. The flexible and pliable features increase the efficiency of inductive power transfer and can reduce charge times and/or reduce heat generated due to thermal losses.

Disclosed is a charging case, comprising a control module, a charging case battery and a voltage conversion module; the charging case battery is connected with the voltage conversion module; the voltage conversion module is configured for converting a direct current output by the charging case battery into a charging voltage and outputting the charging voltage to a charging management chip of a to-be-charged device so as to charge a battery of the to-be-charged device through the charging management chip; the control module is configured to regulate the charging voltage output by the voltage conversion module according to a voltage of the battery of the to-be-charged device during charging of the battery of the to-be-charged device.

An ear-worn electronic system comprise a plurality of discrete devices configured for deployment at one ear of a wearer. The system comprises a first device configured for placement at least partially within an ear canal of the wearer. The first device comprises at least a first processor, one or more first microphones, a first speaker, a first rechargeable battery, and first charging circuitry. The system comprises a second device configured for placement at the wearer's ear proximal of the first device in an outer ear direction. The second device comprises at least a second processor, a second rechargeable battery, and second charging circuitry. The first device is configured to operate autonomously when operating in an independent mode relative to the second device. The first and second devices are configured to operate cooperatively when operating in a communicatively coupled mode.

The present disclosure provides a wireless earphone device and method for using the wireless earphone device. The wireless earphone device comprises a processing unit, a switch unit, a wireless transceiving unit, a language input unit, and a speaker unit. The switch unit is electrically connected to the processing unit. The wireless transceiving unit is electrically connected to the processing unit, transmitting wirelessly with the earphone. The language input unit is electrically connected to the processing unit. The speaker unit is electrically connected to the processing unit. While the earphone charging case is activated and switched to a translation mode by the switch unit, a first voice signal is inputted into the processing unit through the earphone, the processing unit processes the first voice signal into a second voice signal, and the second voice signal is emitted by the speaker unit.
