Abstract: A voice signal detection method, a terminal device and a storage medium. Said method comprises: receiving a time domain signal detected by a bone conduction sensor in the terminal device, and acquiring time domain features in the time domain signal (S10); converting the time domain signal into a frequency domain signal, and acquiring frequency domain features in the frequency domain signal (S20); and when the time domain feature satisfies a first preset condition and the frequency domain feature satisfies a second preset condition, determining that a voice signal has been detected by the bone conduction sensor (S30). The voice detection is performed according to a signal detected by the bone conduction sensor, without the need of combining with a signal detected by a microphone, so that the voice detection is simpler, and moreover, as voice recognition is performed merely in combination with the bone conduction sensor, the cost is low.

Abstract: An apparatus and a method for force sensing, and an electronic device. The apparatus includes at least one first sensor, at least one second sensor, and a comparator. The at least one first sensor generates a first signal, the at least one second sensor generates a second signal, and the comparator receives both the first signal and the second signal. The first signal is determined by deformation of a deformable portion and temperature at the deformable portion, and the second signal is determined by the temperature at the deformable portion. The comparator determines whether the deformable portion deforms based on the first signal, the second signal, and the threshold signal, and further generates the third signal which is in the active state in response to the determination being positive. The apparatus can make an accurate response when the deformation of the deformable portion serves as an input operation.
