1. Features
Power Voltage: 9V--15V;
PCB Dimensions: 160mm*42mm.
2. Circuits Principle
The circuit is mainly composed by Power Circuit, Audio Amplifier Circuit, Frequency Dividing Circuit and LED Driver Circuit.
1) Power Circuit: The power output voltage is 9V--15V. D1 can avoid the demage of three terminal regulator when the power polarity is connected in a wrong way. After the C4's filtering , L7806 three terminal regulator will provide the whole circuit with a stable voltage of 6V.
2
)
Audio Amplifier Circuit: Electret microphone MK1 transfers the obtained sound to electric signal which will be amplifed twice by Q1 and Q2. At this time, UR1 can adjust the size of Q2 signal in order to adjust the sensitivity of the whole circuit.
3
)
Frequency Dividing Circuit: Three frequency dividing circuits is added to indicate the electrical level on the different frequency, as it's featured with three sections of LED indicator in a seperate way. VR2, VR3 and VR4 are used for adjusting the sensitivity of LED indicator on the different frequency. The sound signal from three different frequency can be distinguished according to the different capability of C6, C10 and C11. Q4, Q5 and Q18 collectors can obtain three different frequency and the voltages after dividing and amplifying by diode and transistor. The level of voltage depends on the size of the sound from outside.
4
)
LED Driver Circuit: There are 9 pieces of 1N4148 diode in each frequency. If the sound is louder, the higher voltage will be obtained by Q4,Q5 and Q18 connector and more 1N4148 start work. Then more LEDs can light.

Purchasing & Delivery
Before you make your purchase, it’s helpful to know the measurements of the area you plan to place the furniture. You should also measure any doorways and hallways through which the furniture will pass to get to its final destination.Picking up at the store
Shopify Shop requires that all products are properly inspected BEFORE you take it home to insure there are no surprises. Our team is happy to open all packages and will assist in the inspection process. We will then reseal packages for safe transport. We encourage all customers to bring furniture pads or blankets to protect the items during transport as well as rope or tie downs. Shopify Shop will not be responsible for damage that occurs after leaving the store or during transit. It is the purchaser’s responsibility to make sure the correct items are picked up and in good condition.Delivery
Customers are able to pick the next available delivery day that best fits their schedule. However, to route stops as efficiently as possible, Shopify Shop will provide the time frame. Customers will not be able to choose a time. You will be notified in advance of your scheduled time frame. Please make sure that a responsible adult (18 years or older) will be home at that time.In preparation for your delivery, please remove existing furniture, pictures, mirrors, accessories, etc. to prevent damages. Also insure that the area where you would like your furniture placed is clear of any old furniture and any other items that may obstruct the passageway of the delivery team. Shopify Shop will deliver, assemble, and set-up your new furniture purchase and remove all packing materials from your home. Our delivery crews are not permitted to move your existing furniture or other household items. Delivery personnel will attempt to deliver the purchased items in a safe and controlled manner but will not attempt to place furniture if they feel it will result in damage to the product or your home. Delivery personnel are unable to remove doors, hoist furniture or carry furniture up more than 3 flights of stairs. An elevator must be available for deliveries to the 4th floor and above.
