The **AS03808PR-R** is a high-performance, miniature dynamic speaker manufactured by **PUI Audio**. It is specifically designed for applications where space is limited but high-quality sound reproduction is required. --- ## 1. Technical Specifications The following table outlines the core electro-acoustic characteristics of the component: | Parameter | Specification | | :--- | :--- | | **Rated Input Power** | 0.5 Watts | | **Maximum Input Power** | 1.0 Watts | | **Impedance** | 8 Ohms (±15%) | | **Sound Pressure Level (SPL)** | 85 dB ± 3dB @ 0.5W, 10cm | | **Resonant Frequency (Fo)** | 500 Hz (±20%) | | **Frequency Range** | 500 Hz ~ 20,000 Hz | | **Magnet Material** | NdFeB (Neodymium) | | **Diaphragm Material** | Mylar | --- ## 2. Physical Dimensions and Build The "3808" in the part number typically refers to its dimensions. * **Size:** 38mm x 38mm (Square profile). * **Depth:** Extremely thin (8mm height), making it ideal for flat-panel integration. * **Weight:** Approximately 11.5 grams. * **Termination:** Lead wires for easy soldering or connector attachment. --- ## 3. Key Electronic Features ### Neodymium Magnet (NdFeB) The use of Neodymium allows the speaker to be much thinner and lighter than traditional ferrite speakers while maintaining high flux density. This results in better sensitivity and clearer audio output. ### Mylar Diaphragm The Mylar cone is resistant to moisture and environmental factors, making this speaker suitable for industrial or outdoor-adjacent applications where humidity might be a concern. ### Wide Frequency Response Unlike basic buzzers, the AS03808PR-R has a flat response up to 20kHz. This allows it to reproduce human speech and music with high fidelity, rather than just simple notification tones. --- ## 4. Common Applications * **Point-of-Sale (POS) Terminals:** For voice prompts and feedback. * **Medical Instrumentation:** For clear audible alarms and monitoring alerts. * **Security Systems:** Used in control panels for intercom communication. * **Consumer Electronics:** Handheld devices and smart home hubs.
