The **AS06608PS-WR-R** is a high-quality, miniature waterproof speaker manufactured by **PUI Audio**. It is designed for applications requiring clear audio output in environments where moisture or dust may be present. --- ### 1. Key Technical Specifications | Parameter | Specification | | :--- | :--- | | **Manufacturer** | PUI Audio | | **Speaker Type** | Dynamic, Permanent Magnet | | **Rated Power** | 2 Watts | | **Maximum Power** | 3 Watts | | **Impedance** | 8 Ohms | | **Frequency Range** | 300 Hz ~ 20,000 Hz | | **Sound Pressure Level (SPL)** | 84 dB @ 1W/0.5M | | **Dimensions** | 66mm (Length) x 66mm (Width) x 21.5mm (Depth) | | **IP Rating** | IP67 (Waterproof & Dustproof) | --- ### 2. Physical & Material Composition * **Cone Material:** Typically constructed with a **Mylar (Plastic)** or treated paper cone. Because it is rated IP67, the cone and the surround are designed to repel water and prevent moisture from entering the motor assembly. * **Frame:** Ruggedized plastic housing to prevent corrosion. * **Wiring:** The "WR" in the suffix usually denotes that the part comes with **lead wires** pre-attached (often with a connector), making it easier to integrate into a chassis without direct soldering to the speaker terminals. --- ### 3. Electrical Characteristics The device operates on standard electromagnetic principles: * **Voice Coil:** A precision-wound copper coil that reacts to the magnetic field. * **Magnet:** Utilizes a high-flux magnet (often Neodymium or Ferrite) to maintain a slim profile while providing high sensitivity. * **Resonant Frequency (Fs):** Roughly 300 Hz, meaning it is optimized for voice and mid-range audio rather than deep bass. --- ### 4. Typical Applications Due to its waterproof rating and compact size, this speaker is frequently found in: 1. **Marine Electronics:** GPS units and fishfinders. 2. **Outdoor Security:** Intercoms and smart doorbells. 3. **Industrial Equipment:** Control panels in wash-down environments. 4. **Medical Devices:** Portable equipment that requires frequent sanitization.
