AI Technical Summary

Technical Problem

Existing motion-sensing sound-triggering technology for track toys has limitations in terms of accuracy and reliability. Mechanical contact switches are prone to wear and aging, and photoelectric sensors are easily affected by ambient light, resulting in an unstable sound-effect interaction experience.

Method used

The magnetic field distortion signal caused by the permanent magnet marker at the bottom of the moving vehicle is captured by magnetic field induction technology. The real-time track position and speed are determined by multi-node time sequence comparison, sound effect triggering command is generated, and the directional sound generation component is driven to output through segmented progressive sound field projection control.

Benefits of technology

It achieves precise, stable, and responsive interactive sound effects, overcoming the wear and aging problems of mechanical triggering and the ambient light interference of photoelectric sensing, thus improving the quality of interactive track toys.

Abstract

This invention belongs to the field of intelligent toy control technology. It discloses an interactive track toy sensing sound effect interaction system and method, comprising: capturing the magnetic field distortion signal of the permanent magnet marker at the bottom of the moving carrier through a magnetic induction array within the track; performing multi-node time-series comparison of the distortion signal, and determining the real-time track position and speed parameters based on the peak arrival time difference and amplitude attenuation characteristics; matching the position coordinates with the boundary of the scene trigger section to generate a sound effect trigger command; retrieving sound effect segments according to the scene type, dynamically adapting the playback rate and pitch based on the speed parameters to generate speed-related sound effect data; and implementing segmented progressive sound field projection according to the progressive position sequence of the moving carrier, driving the directional sound-generating components to output sequentially; greatly improving the quality of interactive track toy products.
