Two-way flashing light string circuit with music

A novel flashing light string controller suitable for Christmas tree decoration . It has two flash inputs
and a memory of S music. Its characteristic is that the light string can flash alternately synchronously with the rhythm of the music, and the buttons can control
the music sound. size and the way the light jumps. The core device of the fb circuit is the special MCSIP light control integrated circuit
    produced by Shenzhen Tianlang Semiconductor Co., Ltd. The rU circuit is packaged in DIP-1-1. Black paste soft packaging can also be provided according to customer requirements. The working voltage is typical The value is 4W. The SI and S2 terminals are used to drive the transistors VT and VT2 directly to control the flashing of the light string; VOI. The end is the volume control end. Each time you press SB, you can change the light flashing mode and the music sound volume. Press Qiku Big (the bright lights alternate synchronously), Sound Medium (the bright lights alternate synchronously), and the volume is small (double lights alternate l-step ). ), silent (sister-in-law lights alternate synchronously), silent (both women light up at the same time) cycle selection ; RZ terminal is the music output terminal, and the output music is passed through Rr. The transistor VT3 is amplified to drive the piezoelectric ceramic piece B to amplify; the X and Y terminals are externally connected to the oscillation resistor R. , to determine the chip oscillation frequency.     VT1 and VT2 are optional (8-1) //400--600V small plastic one-way gate, such as 2N6565, MCR100-8, etc. B is a piezoelectric ceramic speaker or an ordinary piezoelectric ceramic chip of ≠27mm . Other components have special requirements.
