Abstract

本实用新型是一种内外永磁动圈式扬声器,其特 征在于其音圈内有钕铁硼永久磁芯,音圈外套有钕铁 硼永久磁环。
本实用新型具有体积小音量大的特点。

Description

本实用新型涉及一种电子器件,特别是一种永磁动圈式扬声器。
现有永磁动圈式扬声器分内磁式和外磁式两种,当永磁体较小时,发出的声音音量受限制,制造超小型收音机(或放音机)只能采用耳机式或耳塞式扬声器。
本实用新型的目的是提供一种高效能的内外永磁动圈式扬声器。
本实用新型按下述方案实现:
本实用新型的永磁体采用钕铁硼磁性材料,包括外磁环和内磁蕊,外磁环套在内磁蕊上,两者之间的间隙内设置有音圈。
本实用新型具有体积小放音量大的特点。
以下结合附图和实施例对本实用新型的结构进行更详细的描述。
图1是本实用新型结构示意图。
如图所示,1、为内磁蕊,2、为外磁环,均由钕铁硼永久磁体材料制成,3、为音圈,4、为振动膜,5、为纸盆骨架,6、为纸盆。
本实用新型还可以用在耳机式或耳塞式上。
