Introduction
The Bluetooth speaker and Boombox market continues to grow strong, driven by outdoor portable audio and mobile sound applications. These use cases demand speakers with high power output, portability, and durability. The 57mm multimedia outer magnet speaker has become a popular choice among Bluetooth speaker manufacturers, offering excellent power performance and superior sound quality. This article provides a detailed analysis of 57mm speakers for Bluetooth audio applications.
What is a Multimedia Outer Magnet Speaker?
A multimedia outer magnet speaker features an external magnet structure where the magnetic circuit is positioned outside the voice coil. Compared to inner magnet designs, outer magnet speakers offer greater magnetic flux density and stronger driving force. XDEC Electronics Co., Ltd. produces multimedia outer magnet speakers spanning 40-210mm, widely used in Bluetooth speakers, desktop audio systems, and soundbars.
Key Advantages of 57mm Outer Magnet Speakers
High Power Output: Rated power of 10-15W, moving more air for powerful bass
Outer Magnet Structure: High magnetic efficiency with strong driving force for rich, full sound
Superior Heat Dissipation: External magnet design enables fast heat dissipation, supporting extended high-power operation
Cost-Effective: More affordable compared to equivalent inner magnet speakers
Wide Compatibility: 57mm is an industry-standard size with mature supporting ecosystem
