Abstract

A process executing on an acceleration sensitive sound producing apparatus, comprising: generating accelerometer output signals comprising magnitude and direction of acceleration sensed by a three axis accelerometer; processing, by a microcontroller, the accelerometer output signals into a pulse width modulation timer input signal; modulating, by an interrupt timer, a pulse width modulation timer according to the pulse width modulation timer input signal; generating, by the pulse width modulation timer, a pulse width modulation timer output signal; regulating, by the pulse width modulation timer, playback speed of stored sound according to the pulse width modulation timer input signal, comprising: increasing playback speed when the magnitude of acceleration increases, decreasing playback speed when the magnitude of acceleration decreases; and/or increasing playback speed when change in the direction of acceleration increases, decreasing playback speed when change in the direction of acceleration decreases; playing back the stored sound according to the regulated playback speed.

Abstract

The device includes an accelerometer for sensing a parameter of movement, such as direction and/or magnitude. A pre-recorded sound is played in response to the sensed movement. The speed and/or pitch at which the pre-recorded sound is played is a function of the sensed movement parameter. There may be one or more pre-recorded sounds from which playback is chosen. In one embodiment, hardwired circuits set the characteristics of the generated sound in accordance with the accelerometer output. In a second embodiment, the software selects which pre-recorded sound to play and sets the characteristics of the sound based upon parameters sensed by the accelerometer.

Abstract

The device includes an accelerometer for sensing movement in more than one direction, a sound chip for generating a pre-recorded sound in response to the sensed movement and a circuit for controlling the speed at which the pre-recorded sound is generated in response to the sensed movement, as a function of the direction of the sensed movement. The accelerometer senses the magnitude of movement. The sound chip generates sound in response to movement of a magnitude exceeding a pre-set level. The accelerator senses movement in at least two, preferably three directions. The sound chip includes an oscillator which determines the speed at which a pre-recorded sound is processed. The control means provides a control signal which sets the sound chip to generate the sound signal with a speed which is a function of the number of directions of sensed movement.
