助听器麦克风有哪些常见故障?

助听器麦克风常见的故障现象有声弱,失真以及无外界声音的放大声等,故障原因的外界因素如污物,进水等。对于有T档的助听器,故障的检查比较容易。打开助听器电源开关,将助听器置于T档是工作正常,置于M档时工作不正常,则故障位置可能是麦克风。对于只有M档的助听器,可通过调节音量电位器的方法检查麦克风的工作情况。打开助听器电源开关,此时能听到电流声,调节音量电位器由大到小,电流声也由小到大,则故障位置可能是麦克风。

同样,麦克风也是非常灵敏的元件,在更换时要注意不要直接焊接麦克风,如果要焊接则控制焊接的温度和时间。高温会改变麦克风的性能指标,影响助听器的参数。同时注意导线的走向,以避免内部机械振动噪音,并对导线加以固定,提高使用的可靠性。因此,采用原厂的麦克风套件,类似于受话器套件,包括焊接好的麦克风,标准长度并固定好的导线,麦克风道声管和护套,以维修后的助听器的各项参数指标符合维修标准。
