双声道便携蓝牙音箱的设计与实现

Design and Implementation of Dual Channel Portable Bluetooth Soud Box

蓝牙技术是一种近距离无线通信技术,可以用来取代传统数字设备之间的电缆连接,在多个领域已经得到了广泛的应用。本文介绍了一种蓝牙音箱的原理和设计制作过程。该音箱主要由蓝牙信号接收和功放模块、音频发光二极管指示模块、喇叭、电池模块、外壳组成。经测试该音箱不仅实现了声音的播放,而且用发光二极管灯带直观显示声音音量和节奏的变化。该音箱有体积小、便于携带、配对快、无延迟、音质优美等特点。

Bluetooth technology is a near-field wireless communications technology that can be used to replace cable connections between traditional digital devices and has been widely applied in multiple fields.This article introduces the principle,design,and implementation of a Bluetooth sound box.The sound box consists of a Bluetooth signal receiving and power amplifier module,an audio LED indicator module,two speakers,a battery module,and a shell.After testing,the sound box not only achieves sound playback,but also visually displays changes in sound volume and rhythm using LED light strips.This sound box has the characteristics of small size,easily carrying,fast pairing,no delay,and good sound quality.
