The **ASX10108-SPD-R** is a specific electronic component typically categorized as a **Micro-Speaker** or a **Micro-Transducer**. It is designed for compact electronic devices where space is limited but audio output is required. Below is a detailed breakdown of its specifications and electronic characteristics. --- ### 1. Technical Specifications The following table outlines the typical electrical and physical parameters for this series: | Parameter | Specification (Typical) | | :--- | :--- | | **Component Type** | Micro Dynamic Speaker | | **Impedance** | 8 Ohms (±15%) | | **Rated Power** | 0.7W - 1.0W | | **Max Power** | 1.2W | | **Sound Pressure Level (SPL)** | ~90 dB @ 0.1W/0.1m | | **Resonant Frequency (Fo)** | 850 Hz ± 20% | | **Frequency Range** | 850 Hz ~ 20,000 Hz | | **Dimensions** | ~10mm x 10mm x 3.5mm (Small Form Factor) | --- ### 2. Key Electronic Components & Materials * **Diode/Protection:** While not an active semiconductor, "SPD" in some naming conventions refers to **Surge Protection Devices** or specific damping; however, in this context, it usually denotes a specific mounting/packaging style (Spring Contact/SMD). * **Voice Coil:** Uses high-temperature copper wire wound around a bobbin, which reacts with the magnetic field to create movement. * **Magnet Type:** Generally utilizes **NdFeB (Neodymium)** magnets to provide high flux density in a tiny footprint. * **Diaphragm:** Made of PEI or Mylar plastic for durability and high-frequency response. --- ### 3. Connection & Integration The "R" suffix often indicates **RoHS compliance** or a specific **Tape & Reel** packaging for automated SMT (Surface Mount Technology) assembly. * **Interface:** Usually features **Spring Contacts** or **Solder Pads** on the underside. * **Driving Circuit:** Since it is a dynamic speaker, it requires an analog AC signal. It is typically driven by a Class-D audio amplifier or a simple PWM signal through a transistor for basic beeping functions. --- ### 4. Common Applications Due to its miniature size (10x10mm), this part is commonly found in: 1. **Handheld Terminals:** POS systems and scanners. 2. **IoT Devices:** Smart home sensors and alarms. 3. **Medical Equipment:** Portable monitors and diagnostic tools. 4. **Wearables:** Smartwatches or fitness trackers (if waterproofed).
