Wholesale Pack Configuration This listing is supplied as wholesale packs. The displayed price applies to one complete pack, not to an individual unit. Select the Shopify option that matches the pack configuration you need. Current Shopify option Wholesale specification Pack quantity Default Title 20 pcs/Pack 20 units Each pack uses the 10% bulk discount from the aggregated individual-unit price. The compare-at price represents the total of the original individual-unit prices; the sale price represents one complete pack. Product specifications elsewhere on this page describe the individual item unless a section says otherwise. Unleash the potential of your DIY audio projects with the AKE-1 Mini Speaker Amplifier Kit, featuring the powerful PAM8403 chip. This compact and efficient amplifier delivers impressive sound quality with low distortion, perfect for building your own mini speakers or upgrading existing ones. Parameters Model: AKE-1 Operating Voltage: DC 4.5-5V (Using the included USB power supply is recommended) PCB Size: 42 x 31 mm Features Power Amplifier Chip:The AKE-1 kit utilizes the PAM8403, a Class D audio power amplifier capable of delivering 3W of power with over 85% efficiency. It features high efficiency, high power output, and low distortion. Capacitors:All capacitors used in the audio amplification circuit are monolithic capacitors, which are known for their excellent stability, low-temperature drift, low equivalent series resistance (ESR), and long lifespan. These capacitors are more expensive than ceramic capacitors of the same specification. Note: In the audio cable, light blue represents GND (ground), pink indicates L (left channel), and white corresponds to R (right channel). Usage Notes Power Supply Recommendation:Since the current output from a computer's USB port is limited, connecting the amplifier to a computer's USB may degrade audio quality, especially at high volumes or with heavy bass. A standalone USB power supply (with an output of at least 1A) is recommended for powering the speaker.The included USB power supply provides sufficient power for the AKE-1 amplifier, maximizing the speaker's performance. Preventing Signal Distortion:As the amplifier chip's digital volume control offers high gain, avoid feeding an overly strong input signal to prevent clipping and distortion in the sound. Optimizing Audio Performance:For improved sound quality, consider placing the speakers inside two containers for better resonance.
