Claims (6)
- 音声出力用スピーカー(15)の前方にスピーカーグリル(13)を備えた携帯型無線通信機であって、
前記出力用スピーカー(15)に接続された出力アンプ(17)と、
前記出力アンプ(17)の電源電圧を排水補助機能の動作に合わせて高くする電源電圧切替手段(21)と、
排水補助機能を作動させるための制御手段(22)と、
前記出力アンプ(17)へ受信復調回路(20)からの復調音声信号または制御手段(22)からの排水用信号を切り替えて入力する信号切替手段(18b)を備え、
排水補助機能動作時に、前記制御手段(22)が電源電圧切替手段(21)によって出力アンプ(17)への印加電圧を復調音声出力時の電圧より高い電圧へ切り替え、かつ、
信号切替手段(18b)によって出力アンプ(17)へ排水用信号を連続的に出力することにより、スピーカー(15)への出力電圧の振幅を音声信号出力時よりも大きくして、前記スピーカーグリル(13)内に侵入した水を排水することを特徴とする携帯型無線通信機。 - 上記電源電圧切替手段(21)を、電源電圧を分圧して出力アンプ(17)へ供給する分圧回路と、その分圧回路をバイパスして排水補助機能の動作時に高い電圧を出力アンプ(17)へ印加するスイッチ回路、あるいは、出力アンプ(17)へ排水補助機能の動作時に高い電圧を印加する昇圧回路(21´)で構成したことを特徴とする請求項1に記載の携帯型無線通信機。
- 上記排水用信号の一定レベルの出力が、信号切替手段(18b)へ入力するようにした請求項1または2に記載の携帯型無線通信機。
- 上記出力アンプ(17)の印加電圧の印加時間と排水用信号の入力時間を設定するタイマ手段を備えたことを特徴とする請求項1乃至3のいずれかに記載の携帯型無線通信機。
- 上記グリル(13)とそのグリル(13)の内側に装着した異物侵入防止ネット(14)との間に排水路(16)を設けたことを特徴とする請求項1乃至4のいずれかに記載の携帯型無線通信機。
- 上記排水用信号の生成をマイクロプロセッサのプログラムで行うようにしたことを特徴とする請求項1乃至4のいずれかに記載の携帯型無線通信機。
