Abstract

A decorative device includes a host-controlling device, a decoration, a slave-controlling device, and a mounting structure. The decoration includes a first connection portion. The slave-controlling device is fixed to the decoration and includes a first port, a speaker, and a string light, with the speaker and string light electrically connected to the first port. The mounting structure is installed on an object to be decorated and includes a second connection portion and a second port, selectively electrically connected to the first port. The host-controlling device is electrically connected to the second port. The first connection portion is detachably connected to the second connection portion, allowing the decoration to be detachably connected to the mounting structure. The first and second ports are fixed to the first and second connection portions, respectively, and electrically connected when the decoration is installed.

Dependent claims

An intelligent music synchronization lighting element, comprising:

a human body sensing module configured to sense a human body and output a sensing signal when the human body is sensed;
a control module connected with the human body sensing module, the control module configured to receive the sensing signal and output an enable signal and a control signal according to the sensing signal, generate a synchronized enable signal wherein the enable signal duty cycle is modulated according to musical beat patterns, the enable signal and the control signal being outputted by different output terminals;
a music control module connected with the control module, the music control module configured to receive the enable signal and play a predetermined music according to the enable signal;
and
a lighting element connected with the control module, the lighting element configured to receive the control signal and start to work according to the control signal, a duty cycle of the control signal in each cycle corresponding to beats of each section of the predetermined music, so that the flashing frequency of the lighting element, the beats of the predetermined music, and the frequency of human activity detected by the human body sensing module are synchronized.
