The **AS03604MR-N50-R** is a high-performance, miniature loudspeaker manufactured by **PUI Audio**. It is specifically designed for compact electronic devices where space is limited but audio clarity is essential. --- ### ## Technical Specifications The following table outlines the primary electrical and physical characteristics of the component: | Feature | Specification | | :--- | :--- | | **Manufacturer** | PUI Audio | | **Impedance** | 4 Ohms ± 15% | | **Rated Power (Nominal)** | 2.0 Watts | | **Maximum Power** | 3.0 Watts | | **Frequency Range** | 200 Hz ~ 20,000 Hz | | **Sensitivity (SPL)** | 82 dB @ 1W / 0.5M | | **Magnet Material** | Neodymium (N50) | | **Diaphragm Material** | Mylar (PET) | | **Weight** | ~6.5 Grams | --- ### ## Component Breakdown #### 1. Neodymium N50 Magnet The "N50" in the part number refers to the grade of the Neodymium magnet used. N50 is a high-strength rare-earth magnet that allows the speaker to provide high output and sensitivity while remaining very small and lightweight compared to traditional ferrite magnets. #### 2. Impedance (4Ω) A 4-ohm impedance allows for high current flow at lower voltages, making it ideal for battery-operated devices using Class-D amplifiers that typically run on 3.7V to 5V rails. #### 3. Material Construction - **Frame:** Usually high-temp plastic or metal to ensure structural integrity during soldering. - **Diaphragm:** The Mylar cone is moisture-resistant and provides a crisp response for high-frequency sounds and voice reproduction. --- ### ## Integration and Use Cases ### ### Typical Applications - **Handheld Scanners:** For audible feedback and alerts. - **IoT Devices:** Smart home hubs or security panels. - **Medical Instrumentation:** For diagnostic beeps and voice prompts. - **Portable Electronics:** Bluetooth speakers or ruggedized tablets. ### ### Mounting Considerations The unit typically features solder pads for wire attachment. To achieve the best frequency response (especially the lower range of 200Hz), it is recommended to mount this speaker in a **sealed enclosure** or use a gasket to prevent "acoustic shorting" (where sound waves from the front and back of the cone cancel each other out). ---
