Foldable portable telephone set
View Patent ↗A call tone output system for a foldable portable telephone set having a hinge to be unfolded and folded is disclosed. The call tone output system comprises a detector 14 for detecting the unfolding and folding of the hinge, and a tone output control unit ( 11 and 20 ) for causing tone output from a call tone output unit 8, which outputs a call tone at the time of a call arrival, when a call arrives in the folded state of the hinge, and from a receiver, which outputs a reception tone, when the hinge is unfolded from the folded state.
1. A call tone output system for a foldable portable telephone set having a hinge for being unfolded and folded, comprising:
a detector for detecting the unfolding and folding of the hinge; and
a tone output controller that causes tone output from a call tone output unit upon a call arrival when the hinge is in a folded state, and causes tone output from a receiver when the hinge is unfolded from the folded state.
2. The call tone output system for a foldable portable telephone set according to claim 1 , wherein the tone output controller causes tone output from the receiver at the time of the tone output from the call tone output unit.
3. The call tone output controller for a foldable portable telephone set according to claim 1 , wherein the tone output controller causes tone output from the call tone output unit at the time of the tone output from the receiver.
4. A call tone output system for a foldable portable telephone set having a hinge for being unfolded and folded, comprising:
a detector for detecting the unfolding and folding of the hinge; and
a tone output controller that causes tone output from a call tone output unit upon a call arrival and causes tone output from a receiver when the hinge is unfolded from a folded state.
5. A call tone output system for a foldable portable telephone set having a hinge for being unfolded and folded, comprising:
a detector for detecting the unfolding and folding of the hinge; and
a tone output controller that causes tone output from a call tone output unit upon a call arrival, when the hinge is in a folded state, an unfolded state, or when the hinge is folded from the unfolded state and that causes tone output from a receiver when the hinge is unfolded from the folded state.
6. The call tone output system for a foldable portable telephone set according to claim 5 , wherein the tone output controller causes tone output from the receiver at the time of the tone output from the call tone output unit.
7. A call tone output system for a foldable portable telephone set having a hinge for being unfolded and folded, comprising:
a detector for detecting the unfolding and folding of the hinge; and
a tone output controller that causes tone output from a call tone output unit upon a call arrival when the hinge is in a folded state, an unfolded state, or folded from the unfolded state and that causes tone output from a receiver when the hinge is unfolded from the folded state or when the hinge is folded from the unfolded state.
8. The call tone output controller for a foldable portable telephone set according to claim 7 , wherein the tone output controller causes tone output from the call tone output unit at the time of the tone output from the receiver.
9. A call tone output method for a foldable portable telephone set having a hinge to be unfolded and folded, comprising:
detecting the unfolding and folding of the hinge; and
outputting a call tone from a call tone output unit when a call arrives and the hinge is in a folded state; and
outputting a reception tone from a receiver when a call arrives and the hinge is unfolded from the folded state.
10. A portable telephone set having two member bodies capable of being unfolded and folded, comprising:
a detector for detecting the unfolding and folding of the two member bodies; and
a tone output controller that causes tone output from a call tone output unit upon a call arrival when the two member bodies are in a folded state, and that causes tone output from a receiver upon a call arrival when the two member bodies are unfolded from the folded state.
11. The portable telephone set according to claim 10 , wherein the tone output controller causes tone output only from the call tone output unit when a call arrives in the unfolded state of the two member bodies.
