Latest Patents

Electronic Device Comprising Piezoelectric Device, and Touch Input Detection Method Using Piezoelectric Device. This invention describes an electronic device that uses a piezoelectric element for both touch sensing and audio output. When the device is connected to an external device through short-range communication, switching circuitry can connect the piezoelectric element to a touch sensing circuit. After detecting a touch input, the circuitry can reconnect the element to the audio output circuit to play audio, then return it to touch sensing.

Electronic Device for Outputting Sound and Operating Method Thereof. This invention describes a device that combines a microphone and vibration sensor to improve speech processing. The device receives a user’s speech and related vibrations transmitted through the body, predicts reverberation information from both signals, and uses that information to reduce reverberation in the speech signal.
