Abstract: The present application discloses a protective sleeve, which used for mobile terminals (2), includes a shell (1) and a luminous component (10) provided on the shell (1). The protective sleeve also includes a microphone (3), which is provided on the shell (1) with being used to receive an audio signal and convert it into a pulse signal, and a voice-activated lamp circuit (4), which is provided on the shell (1) with being electronically connected with the microphone (3) and the luminous component (10), respectively and being used to receive the pulse signal and generate a trigger signal corresponding to the pulse signal to turn on and off the luminous component (10). The protective sleeve in the present application is simple and practical, and has some entertainment.

Abstract: A moving toy, e.g. toy car, comprises a body, wheels for moving the body on a surface, and an electric motor provided in the body for driving the wheels. A control circuit is connected to the motor for controlling the performance of the motor. Also included one or more impact detectors connected to the control circuit for detecting an impact acted upon the toy and in response providing a signal to cause the control circuit to reduce the performance of the motor and hence the speed of the car.
