Description

车载有源蜂鸣器
技术领域
本实用新型车载有源蜂鸣器属于传感器领域,特别是涉及一种蜂鸣器。
背景技术
普通的蜂鸣器是由后盖,振动片,防护罩构成,振动片安装在后盖和防护罩内,蜂鸣器没有音膜,声音尖锐,一般的蜂鸣器产品响度低、声压不稳定,温度变化时,容易造成声音衰减。
发明内容
本实用新型的目的在于避免现有技术的不足之处,提供一种结构简单,产品响度高,频带宽,声压稳定的车载有源蜂鸣器。
本实用新型的目的是通过以下措施来达到的,它是由后盖,振动片,振动膜,前腔,防护罩构成,后盖与前腔采用胶水密封,在前腔上设置有防护罩,振动膜安装在前腔上,在振动膜上安装振动片,振动片完全密封在振动膜与后盖之间,振动膜有锥度,前腔与振动膜的结合部是圆弧部。
振动膜安装在前腔上,在振动膜上安装振动片,振动膜带锥度,可以得到更响亮地悦耳的声音。
振动膜与前腔的结合部是圆弧部,振动膜与前腔采用胶水密封,密闭式结构、倾角装配、不积灰尘和雨水。可以使灰尘和雨水无法进入产品内部,使产品的防护更完善,
本实用新型结构简单,产品响度高、频带宽、声压稳定,温度变化时声音大小无衰减,没有安装角度要求。
附图说明
附图1是本实用新型的结构示意图。
附图2是附图1的B部放大示意图。
附图3是本实用新型的立体图。
具体实施方式
以下结合附图对本实用新型作进一步说明。
如附图1所示,本实用新型是由后盖1,振动片2,振动膜3,前腔4,防护罩5构成,后盖1与前腔4采用胶水密封,在前腔4上设置有防护罩5,振动膜3安装在前腔4上,在振动膜上安装振动片,振动片完全密封在振动膜与后盖之间,振动膜有锥度,前腔与振动膜的结合部是圆弧部。
如附图2所示,本实用新型振动膜3安装在前腔4上,前腔与振动膜的结合部是圆弧部。
