The **AS06504PS-X-R** is a high-quality, miniature loudspeaker manufactured by **PUI Audio**. It is specifically designed for applications where space is limited but clear audio output is required. --- ### 1. Key Technical Specifications The following table highlights the primary electrical and mechanical characteristics of the component: | Parameter | Value | | :--- | :--- | | **Impedance** | 4 Ohms (±15%) | | **Power Rating (Nominal)** | 2.0 Watts | | **Power Rating (Maximum)** | 3.0 Watts | | **Sound Pressure Level (SPL)** | 84 dB @ 1W / 0.5M | | **Frequency Range** | 200 Hz ~ 20,000 Hz | | **Resonant Frequency (Fs)** | 350 Hz (±20%) | | **Magnet Material** | Neodymium (NdFeB) | | **Weight** | ~23 Grams | --- ### 2. Component Composition and Design This part is engineered for durability and high-fidelity sound reproduction in a small form factor: * **Neodymium Magnet:** Utilizes a rare-earth Neodymium magnet, which provides a high magnetic flux density. This allows the speaker to be much louder and clearer than traditional ferrite magnets of the same size. * **Cone Material:** Typically features a treated paper or composite cone with a rubber/cloth surround for smooth linear excursion. * **Square Frame:** The "065" in the part number refers to its **65mm x 65mm** square dimensions, making it easy to mount in flat-panel enclosures. * **Environmental Compliance:** The "-R" suffix indicates that the part is **RoHS compliant**, meaning it is free from hazardous substances like lead and cadmium. --- ### 3. Connection and Integration To integrate this part into an electronic circuit, consider the following: * **Amplifier Matching:** Ensure your audio amplifier is stable at a **4-ohm load**. Using a 2W to 5W Class-D amplifier is standard for this component. * **Polarity:** The terminals are usually marked with a (+) and (-) or a red dot. Proper polarity is crucial in stereo or multi-speaker setups to prevent phase cancellation. * **Enclosure Design:** Because it has a resonant frequency (Fs) of 350 Hz, it requires a sealed or ported enclosure to produce adequate "low-end" sound; otherwise, it will sound "tinny" due to acoustic short-circuiting. --- ### 4. Typical Applications * Point-of-Sale (POS) Terminals * Kiosks and Vending Machines * Industrial Control Panels (Audio alerts/instructions) * Portable Medical Instrumentation * Smart Home Hubs
