The **ASX08804-TP-R** is a specialized electronic acoustic component manufactured by **PUI Audio, Inc.** It is a high-performance, micro-sized speaker designed for space-constrained applications that require clear sound output. --- ## 1. Core Technical Specifications The following table summarizes the primary electrical and mechanical characteristics of the ASX08804-TP-R: | Parameter | Specification | | :--- | :--- | | **Component Type** | Dynamic Speaker (Micro) | | **Impedance** | 8 Ohms (±15%) | | **Power Rating (Nominal)** | 0.8 Watts | | **Power Rating (Maximum)** | 1.0 Watts | | **Sound Pressure Level (SPL)** | 88 dB @ 0.1W/0.1M | | **Resonant Frequency (Fo)** | 850 Hz (±20%) | | **Frequency Range** | 850 Hz ~ 20,000 Hz | | **Magnet Material** | NdFeB (Neodymium) | | **Weight** | ~0.6 Grams | --- ## 2. Key Features and Construction The "TP" in the part number often signifies specific termination or packaging styles (typically **Transparent/Tape** or specific **Pin/Pad** configurations depending on the series). ### Mechanical Design * **Dimensions:** It features a very slim profile, typically measuring around **8mm x 8mm** or **10mm diameter** (depending on the specific frame sub-series), making it ideal for wearables. * **Diaphragm:** Usually constructed from Mylar or a similar lightweight polymer to ensure high sensitivity and fast response. * **Mounting:** Designed for Surface Mount (SMD) or lead-wire attachment depending on the exact footprint suffix. ### Material Science * **Neodymium Magnet:** Uses a high-grade NdFeB magnet to provide a strong magnetic field in a tiny footprint, which is essential for achieving the 88dB sensitivity rating. --- ## 3. Typical Applications Because of its small size and relatively high power handling (for its class), it is used in: 1. **IoT Devices:** Smart home sensors and hubs that require voice prompts or alerts. 2. **Medical Portables:** Handheld diagnostic tools or wearable monitors. 3. **Mobile Communication:** High-end walkie-talkies or specialized handsets. 4. **Security:** Compact alarm systems and keypad feedback. --- ## 4. Integration Considerations When designing a PCB for the ASX08804-TP-R, keep the following in mind: * **Enclosure Design:** To achieve the best bass response and prevent phase cancellation, the speaker should be mounted in a sealed or ported back-cavity. * **Driving Circuit:** Can be driven by a standard Class-D audio amplifier. Ensure the gain is set so the peak voltage does not exceed the 1.0W maximum power rating to avoid voice coil burnout. * **Polarity:** Observe the polarity markings (+/-) to ensure phase consistency, especially if using multiple speakers in a single device.
