Product Information PAM8403 Amplifier is a small digital amplifier chip, high-definition sound quality highlights the advantages of digital chips, circuit using the most reasonable peripheral configuration, power supply filtering is upgraded to 470uf (some sellers are less did not even 100uf capacitance) 1.6mm glass sheet, the real amplifier board did the most detailed, high-fidelity sound output 3W + 3W, is a rare good product enthusiasts amplifier, potentiometer using original anti-meter body, potentiometer with switch can cut off the power supply directly counterclockwise. Feature Power range: DC 2.5V – 5.5V Minimum Output: 3W * 2 Dimensions: 29.5 * 20.2 * 15mm Note please make sure the power supply is not more than 5.5V and please don't do reverse polarity for "+" and "-", or else, it will burn the board. Excellent noise suppression, in the absence of circumstances connected to input audio ear close to the speaker can not hear any noise, two-channel stereo, 5V power supply can output 3W 3W power, can directly drive 4Ω, 8Ω small speakers, the output power large, full of energy, good sound quality. The unique non-LC filter Class-D digital power board can be directly used computer USB power supply. Double panel wiring, wiring properly resolve the ground potential caused by balance and inter-channel crosstalk, ultra-miniature design, can easily be placed in a variety of digital products within a small space, high amplification efficiency. All using the whole plate welding machine, welding quality comparable non-manual soldering iron! ! ! Note: The left and right channel output of the "negative" and can not be connected together, otherwise it will burn IC, and should be preceded powered speakers connected (load). Rated working voltage 2.5 ~ 5V, limit operating voltage 5.5V.
How to use:
When an electric current is sent through a coil of wire, it induces a magnetic field. In speakers, a current is sent through the voice coil which produces an electric field that interacts with the magnetic field of the permanent magnet attached to the speaker. Like charges repel each other and different charges attract. As an audio signal is sent through the voice coil and the musical waveform moves up and down, the voice coil is attracted and repelled by the permanent magnet. This makes the cone that the voice coil is attached to move back and forth. The back and forth motion creates pressure waves in the air that we perceive as sound. 5w Speaker
