The **AS01608MS-SC9-WP-R** is a specialized micro-speaker manufactured by **PUI Audio**. It is designed for compact electronic devices requiring water resistance and high-quality sound output in a small footprint. --- ### 1. Key Technical Specifications The following table highlights the primary electrical and physical characteristics of the component: | Parameter | Specification | | :--- | :--- | | **Transducer Type** | Dynamic (Moving Coil) | | **Impedance** | 8 Ohms ± 15% | | **Power Rating** | 0.8W (Nominal) / 1.0W (Max) | | **Sound Pressure Level (SPL)** | 88 dB ± 3dB @ 0.1W/0.1M | | **Resonant Frequency (Fo)** | 550 Hz ± 20% | | **Frequency Range** | 550 Hz ~ 20,000 Hz | | **Ingress Protection** | IP67 (Dust tight and Waterproof) | | **Dimensions** | 16mm x 8mm x 3.7mm | --- ### 2. Physical Design Features * **Form Factor:** It features a rectangular, "slim-line" design, making it ideal for integration into modern, thin electronics where circular speakers cannot fit. * **Material Construction:** * **Diaphragm:** Typically made of PEEK (Polyether ether ketone) or similar high-performance polymers to withstand moisture. * **Magnet:** Uses high-energy **Neodymium (NdFeB)** magnets to maximize output while minimizing weight. * **Connectivity:** The "SC" in the part number often denotes **Spring Contacts** (Gold-plated), allowing for solderless assembly onto a PCB. --- ### 3. Special Designations The suffix of the part number provides critical information regarding its environmental capabilities: * **WP (Waterproof):** This indicates the speaker is designed with a waterproof membrane. It carries an **IP67 rating**, meaning it can be submerged in 1 meter of water for up to 30 minutes without damage. * **R (RoHS):** Compliant with environmental standards for restricted hazardous substances. --- ### 4. Common Applications Due to its ruggedized and compact nature, this part is commonly used in: 1. **Wearables:** Smartwatches and fitness trackers. 2. **Handheld Devices:** Industrial scanners or GPS units used outdoors. 3. **Medical Devices:** Portable monitors that require easy cleaning and disinfection. 4. **IoT Sensors:** Smart home devices located in kitchens or bathrooms. ---
