Portable communication device with speakerphone operation
First Claim
1. A portable communication device comprising:
- a first housing element containing a microphone;
a second housing element that is movably connected to the first housing element and settable to a substantially open position and a substantially closed position relative to the first housing element, the second housing element containing a single speaker having a first speaker side and a second speaker side, the second housing element having a front surface formed to have an earpiece opening for transmitting audio signals from the first speaker side when the second housing element is in the substantially open position, the second housing element having a back surface formed to have a speakerphone opening for transmitting audio signals from the second speaker side when the second housing element is set to the substantially closed position;
a sensor coupled to the first housing element and the second housing element for detecting a position of the second housing element relative to the first housing element and producing a position signal;
an activation element disposed on one of the first housing element and the second housing element, the activation element producing an activation signal in response to a user input; and
a controller carried in one of the first housing element and the second housing element, the controller for operating the portable communication device in one of a standby mode, a speakerphone mode, and a private mode in response to the position signal and the activation signal.

Abstract
A radiotelephone (100) comprises a first housing element (202) and a second housing element (204), wherein the second housing element (204) is movingly connected to the first housing element (202) such that the second housing element (202) is settable to a substantially open position and a substantially closed position. A single speaker is utilized for private mode operation when the second housing element (202) is in the substantially open position and speakerphone operation when the second housing element (202) is in the substantially closed position. An internal opening (209), a first sound (270), and a second sound port (211) port sound such that the inside of the first housing element (202) acts as an acoustical suspension enclosure to improve audio quality in the speakerphone mode of operation.

8. A radiotelephone comprising:
-
a first housing element containing a microphone and formed to have an internal cavity for functioning as an acoustical suspension enclosure, the first housing element formed to have a first sound port located on a surface of the first housing element such that the internal cavity is acoustically coupled to the first sound port; a second housing element that is movably connected to the first housing element and settable to a substantially open position and a substantially closed position relative to the first housing element, the second housing element containing a single speaker having a front speaker side, a back speaker side, and a speaker magnet, the second housing element having a front surface formed to have an earpiece opening for transmitting audio signals from the back speaker side when the second housing element is in the substantially open position, the second housing element having a back surface formed to have a speakerphone opening for transmitting audio signals from the front speaker side when the second housing element is set to the substantially closed position, the second housing element formed to have an internal opening and a second sound port, the second sound port located on the front surface of the second housing element such that the second sound port is in fluid communication with the speaker through the internal opening, the second sound port substantially identical in shape and size as the first sound port and positioned such that the first sound port and the second sound port substantially align and couple when the second housing element is set to the substantially closed position, thereby allowing acoustical signals to be coupled from the speaker to the internal cavity of the first housing element; a sensor coupled to the first housing element and the second housing element for detecting a position of the second housing element relative to the first housing element and producing a position signal; an activation element disposed on one of the first housing element and the second housing element, the activation element producing an activation signal in response to a user input; and a controller carried in one of the first housing element and the second housing element, the controller for operating the radiotelephone in one of a standby mode, a speakerphone mode, and a private mode in response to the position signal and the activation signal. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)
