Abstract: An interactive electronic toy includes a body, a sensor module, a data storage module, an output module and a processing unit. The sensor module generates sensing signals when the body is being operated. The data storage module has stored therein standard status parameters each having an accurate response signal. The processing unit runs an operation mode subject to the steps of: receiving the sensing signals and processing the sensing signal into an actual parameter, receiving the standard status parameters, matching the actual parameters with the standard status parameters, and outputting to the output module the accurate response signal of the standard status parameter that matches the actual parameter.

Abstract: A chorusing toy system includes multiple sound-generating devices. The sound-generating devices each include a storage module, a sound-generating unit, and a circuit module. The storage module stores a role-related datum, an ID datum, and at least a play datum. The circuit module is connected to the storage module and the sound-generating unit, and includes a starting switch and a playing switch. Once the starting switches are turned on, the circuit modules will execute a connection procedure whereby one of the sound-generating devices is defined as a master. Once the playing switches are turned on, the circuit modules will execute a playing procedure whereby the play datum are played by means of a playing unit of the sound-generating devices.
