摘要： A vibration signal generation apparatus includes an absolute value signal generator configured to generate an absolute value signal by detecting an absolute value of amplitude of an acoustic signal, an envelope signal generator configured to generate an envelope signal by detecting an envelope of the absolute value signal, a differentiator configured to differentiate the envelope signal, an amplitude limiter configured to generate an amplitude-limited signal by limiting amplitude of the envelope signal so that an amplitude value of the differentiated envelope signal becomes zero or greater, and a vibration signal generator configured to generate a vibration signal by multiplying the amplitude-limited signal by a reference signal having a frequency that allows a human to perceive a vibration.

摘要： An electronic device such as a speaker device may have a curved housing characterized by a vertical longitudinal axis. A layer of fabric may cover the curved housing. A touch sensor may be used to detect touch input on the layer of fabric. The touch sensor may include capacitive touch sensor electrodes including drive lines and sense lines. In some arrangements, the touch sensor is formed from conductive strands in the layer of fabric. In other arrangements, the touch sensor is formed from conductive traces on a substrate. The substrate may be formed from portions of the curved housing or may be formed from a layer that is separate from the housing. Light-emitting components and/or fabric with different visual characteristics may be used to mark where the touch-sensitive regions of the fabric are located. The touch-sensitive regions may be shaped as media control symbols.
