Abstract
Abstract Portable wireless telephone handset with a flap movable upon a housing. In a first position the flap is close to a speaker to enable the flap to be disposed near to a user's ear for the user to receive personal low volume sound from the speaker. In a second position, the flap is further from the speaker to detract from use of the speaker near to the user's ear. In the second position of the flap, the speaker operates in loudspeaker mode. A switch is provided to change the speaker between loudspeaker and low volume sound mode, the switch operation being dependent upon flap position.
