The **LSMT2-10560-R** is an electronic component typically categorized as a **Surface Mount (SMT) Magnetic Transducer** or **Buzzer**. These parts are designed to convert electrical signals into audible sound, commonly used for notifications in portable electronics. --- ### ## 1. Technical Specifications Below are the typical characteristics of the LSMT2-10560-R series: | Parameter | Value/Description | | :--- | :--- | | **Type** | Magnetic Transducer (Requires external drive circuit) | | **Mounting Type** | SMT (Surface Mount Technology) | | **Operating Voltage** | 3V - 5V (Typical peak-to-peak) | | **Rated Current** | Max 80mA - 100mA | | **Sound Pressure Level (SPL)** | 85dB+ at 10cm | | **Resonant Frequency** | ~2700 Hz (Standard for this series) | | **Operating Temperature** | -40°C to +85°C | --- ### ## 2. Key Components & Construction The "10560" in the part number usually refers to its physical dimensions (approx. **10mm x 10mm x 5.6mm**). The internal structure includes: 1. **Housing:** A High-Temperature Plastic (LCP) case designed to withstand reflow soldering temperatures. 2. **Diaphragm:** A thin metal plate that vibrates when subjected to a magnetic field. 3. **Electromagnet:** A coil of fine copper wire wound around a core. 4. **Permanent Magnet:** Provides the bias field necessary for the diaphragm to move. 5. **Terminals:** Gold-plated or tin-plated pads for soldering to a PCB. --- ### ## 3. Operating Principle Unlike a "piezo" buzzer which acts like a capacitor, a **magnetic transducer** like the LSMT2-10560-R acts like an inductor. * **Input Requirement:** It requires a square wave (PWM signal) at its resonant frequency to produce sound. * **Driving Circuit:** You cannot simply apply a DC voltage to it. You must use a transistor (NPN or MOSFET) to switch the current through the coil. ```python # Pseudo-code logic for driving a magnetic transducer while True: set_pin(HIGH) delay(1/2700 / 2) # Delay for half of the resonant period set_pin(LOW) delay(1/2700 / 2) ``` --- ### ## 4. Common Applications * **Medical Devices:** Alarms for handheld monitors. * **Consumer Electronics:** Microwave beepers, digital clocks. * **Industrial:** Status indicators on control panels. * **IoT Devices:** Audible feedback for smart home sensors.
