### AS01508MS-SC11-WP-R Component Overview The **AS01508MS-SC11-WP-R** is a high-performance, miniature waterproof speaker manufactured by **PUI Audio**. It is part of their "Mobile Series" and is specifically designed for high-fidelity audio output in compact, rugged environments. --- ### Technical Specifications | Parameter | Specification | | :--- | :--- | | **Type** | Dynamic Speaker (Moving Coil) | | **Impedance** | 8 Ohms ± 15% | | **Power Rating (Rated/Max)** | 0.8W / 1.0W | | **Sound Pressure Level (SPL)** | 86 ± 3 dB @ 0.1W/0.1M | | **Frequency Range** | 500 Hz ~ 20,000 Hz | | **Resonant Frequency (Fs)** | 500 Hz ± 20% | | **IP Rating** | IP67 (Dust tight and Water immersion) | | **Dimensions** | 15mm x 11mm x 3.9mm | --- ### Key Features and Construction * **Waterproof Protection:** The "WP" in the part number denotes its **IP67 rating**. This is achieved through a specialized synthetic diaphragm and internal gaskets that prevent water ingress without significantly dampening sound quality. * **Magnet Material:** Utilizes high-strength **NdFeB (Neodymium)** magnets, which allow for a high power-to-size ratio, providing loud output in a very thin profile. * **Connection Method:** Features **Solder Pads** for secure electrical termination. * **Compact Footprint:** At only 3.9mm thick, it is ideal for modern handheld electronics where internal space is at a premium. --- ### Common Applications 1. **Handheld Devices:** Two-way radios, scanners, and ruggedized smartphones. 2. **IoT & Wearables:** Smart watches or outdoor sensors that require audible alerts. 3. **Medical Devices:** Portable monitoring equipment that needs to be cleaned/sanitized. 4. **Industrial Equipment:** Control panels exposed to moisture or outdoor environments. --- ### Driving the Component To integrate this speaker into a circuit, a small Class D audio amplifier is typically recommended for efficiency. ```cpp // Conceptual pseudo-code for generating a simple alert tone void playAlert(int pin, int frequency, int duration) { tone(pin, frequency); // Generate square wave to drive the speaker delay(duration); // Play for specified time noTone(pin); // Stop signal } ```
