The 7812 is a 12v DC regulator that takes an input volt up to 44v and outputs 12v ( i believe there can be a 32v between the input and the output so 12+32=44 but check the data sheet). So to answer your question the 7812 is a voltage source that more than likely powers the rest of the circuitry in the clap switch, such as the relay, amp for microphone and any other devices.

Can you explain how to connect a type 7812 voltage regulator ic?
A Type 7812 voltage regulator ic (integrated circuit) is 3-terminal device with separate pins for Input, Output and Ground.Basically you connect a suitable source (a battery or a power supply unit that plugs into the house's main electricity service) to the Input pin and the Ground pin. Connect your load device (the equipment which requires a regulated voltage) to the Output pin and the Ground pin.You can find circuit diagrams for using this type of voltage regulator IC in electronics textbooks and often in the catalogs produced by suppliers of electronic components.For technical and licensing reasons circuit diagrams cannot be included within the answers on this site.The Related Link shown below gives detailed information about the ic itself, including its own internal circuit diagram.

What resistor makes 10v into 5v?
You can't use one resistor to bring a voltage down, you have to use two in series in a voltage divider configuration, that is two resistors of the same value in serie between positive and negative, then you will have 5V between negative and the point between the resistors, any value can be used depending on the current jou are going to draw, note: you can not use to small a value at least 1K or up, if the value is to small the resistor will get to hot and it can burn out or it can burn your power supply or you can simply use a 7805 voltage regulator chip, it is inexpensive and easy to use, it only have 3 pins 1 = input, 2=GND and 3 is your output, one can get it in many deferent voltages 7803,7805, 7808, 7812 etc. Note: you can even adjust the output voltage between 5V and the RMS value of your power supply, by connecting a pot between GND and the center pin of the regulator, a smoothing cap is needed between GND and the input and one between GND and the output 1 to 10 mf 16V

A 7812 transistor is pnp type?
The 7812 is not a transistor. It is an integrated circuit, a voltage regulator designed to regulate an input voltage down to 12 volts output. It typically comes in a TO-220 case, and has three leads, so it sure does look like a transistor though!
Use of transistor 7812?
7812 is not a transistor. It is a three lead voltage regulator integrated circuit. Its maximum input voltage should be near 35 volts. The minimum input voltage should be near 14 volts. The output will be 12 volts.
