The **AS01808PR-N50-R** is a high-performance, miniature speaker manufactured by **PUI Audio**. It is specifically designed for space-constrained applications that require clear sound output, such as mobile devices, scanners, and IoT hardware. --- ### ## Technical Specifications Below are the primary electrical and mechanical characteristics of the component: | Parameter | Specification | | :--- | :--- | | **Speaker Type** | Permanent Magnet Dynamic Speaker | | **Impedance** | 8 Ohms ± 15% | | **Rated Input Power** | 0.8 Watts | | **Maximum Input Power** | 1.0 Watts | | **Frequency Range** | 500 Hz ~ 20,000 Hz | | **Sound Pressure Level (SPL)** | 86 dB @ 0.1W / 0.1M | | **Magnet Material** | NdFeB (Neodymium) | | **Diaphragm Material** | PEEK (Polyether Ether Ketone) | | **Weight** | ~1.5 Grams | --- ### ## Key Electronic Features 1. **Neodymium (NdFeB) Magnet**: Uses a high-grade Neodymium magnet which provides a high magnetic flux density. This allows the speaker to be incredibly small while maintaining high sensitivity and efficiency. 2. **PEEK Diaphragm**: The diaphragm is made of PEEK, a high-performance thermoplastic. This material is chosen for its thermal stability and rigidity, which helps minimize distortion even when driven at its maximum 1W power rating. 3. **Low Profile Design**: The "1808" in the part number typically refers to its dimensions (often approximately 18mm x 8mm). Its rectangular, slim form factor is ideal for modern "slimline" electronics. --- ### ## Application & Mounting * **Connection**: This model usually features **solder pads** for direct wire attachment or PCB integration. * **Polarity**: Polarity is marked (usually a "+" sign or a colored dot) to ensure phase consistency when using multiple speakers. * **Enclosure**: To achieve the best frequency response (especially in the lower 500Hz range), this speaker should be mounted in a sealed or ported acoustic chamber. ---
