PURPOSE:To improve operability and to simplify a connection by permitting one switch to change over an internal speaker, an external speaker and an external woofer. CONSTITUTION:When a speaker changeover switch 6 is in the state of an interior A, a voice output signal 8 is applied only to the internal speaker 7, and only its voice is emitted. When the speaker changeover switch 6 is in an exterior B, the voice output signal 8 passes by the speaker changeover switch 6, and is applied only to an external speaker terminal 2. If the speaker is connected to the external speaker terminal 2, only its voice is emitted. When the speaker changeover switch 6 is in a woofer C, the sound output signal 8 passes by a network capacitor 4. Its low frequency band is cut, and the remainder is applied to the internal speaker 7. It emits voice only in intermediate and high frequencies. |
