Bring Your Audio Projects to Life
Finding the right balance between compact size and clear sound output is crucial for any custom electronics build. Our 52mm Round Full-Range Speaker is engineered to deliver reliable, high-fidelity audio for a wide variety of applications. Whether you are prototyping a smart home device or building a custom desktop radio, this component guarantees a professional audio experience.
Engineered for Clarity and Power
Don't let the compact 52mm diameter fool you. Featuring a premium PU edge surround, this speaker handles a broad frequency range from 150Hz to 20kHz, ensuring your audio doesn't sound tinny or hollow. With a rated power of 5W (peaking at 6W) and a 4 Ohm impedance, it efficiently translates power into clear, distortion-free sound. The robust 45mm magnet provides the driving force necessary for an impressive 95dB/W sensitivity, making it louder and more responsive than standard micro-speakers.
Seamless Integration for Makers and Engineers
Designed with makers in mind, this full-range speaker is incredibly easy to mount and wire into your existing circuits. Its lightweight 84g design and shallow 26mm mounting depth make it a perfect fit for tight enclosures. It pairs flawlessly with mini audio amplifiers and popular microcontroller platforms, making it an essential component for any engineer's toolkit.

FAQ Section
FAQ Section
Q. Do I need an amplifier to use this speaker with a microcontroller?
A. Yes. Microcontrollers output very low voltage. To drive this 4 Ohm 5W speaker effectively and prevent damage to your board, you will need a small audio amplifier module (such as a Class D amp).
Q. Can this be used as a replacement part for commercial electronics?
A. Absolutely. As long as your existing housing can accommodate a 52mm diameter and 26mm depth, and the original system supports a 4 Ohm impedance, this is an excellent replacement unit.
Q. Is the speaker magnetically shielded?
A. This model features a standard exposed 45mm magnet. We recommend keeping it at a safe distance from magnetically sensitive components or old CRT monitors.
