<p>The invention relates to a sound reproduction device on the one hand comprising a transmitter element (100) that comprises: a base (102a) for adapting it in a bush, a receptacle (102b) for receiving at least one light transmitter, a storage medium reader (103) suitable for containing sound files, and a control module (107) for generating a control signal for the light transmitter incorporating a switch established from data contained in the sound files, such that the light transmitter transmits a switched light signal in response to the control signal. Additionally, the device comprises a receiver element (200) that includes a light sensor (202) sensitive to the switched light signal transmitted by the bulb, a control module (205) able to convert the detected switched light signal into an electrical signal, and a sound transmitter (206) able to transmit a sound in response to the electrical signal.</p> |
