Method and apparatus for alerting an operator of an incoming cellular or portable phone call
First Claim
1. An apparatus for notifying a user, comprising:
- a first cylindrical transducer adapted to generate a first acoustic field having a first frequency;
a first frequency generator coupled with said first cylindrical transducer;
a second cylindrical transducer positioned coaxially to said first cylindrical transducer and adapted to generate a second acoustic field having a second frequency not equal to said first frequency; and
a second frequency generator coupled with said second cylindrical transducer, said first and second acoustic fields are proximate to a user'"'"'s tissue, and exhibit an overlapping portion within the user'"'"'s tissue with said overlapping portion generating a vibrational sensation inside the user'"'"'s tissue; and
whereby said vibrational sensation results from a difference frequency generated in the user'"'"'s tissue by said overlapping portion within the user'"'"'s tissue of said first and second acoustic fields.

Abstract
A method and apparatus for notifying a user of an incoming cellular telephone call are provided. The apparatus includes a cellular telephone body having at least a back surface, a first transducer positioned within said cellular telephone body perpendicular to the back surface and adapted to generate a first acoustic field, and a second transducer positioned coaxially to the first transducer and adapted to generate a second acoustic field. A first frequency generator is coupled with the first transducer to drive the first transducer to generate the first acoustic field and a second frequency generator is coupled with the second transducer to drive the second transducer to generate the second acoustic field in response to an indication that an incoming cellular telephone call has been received. The first and second acoustic fields overlap. The overlapping fields generate a vibrational sensation from a difference of frequency from unequal frequencies generated by the first and second transducers. The vibration sensation being maintained from the overlapping fields at a user'"'"'s tissue, thereby indicating to a user that an incoming cellular telephone call has been received. A corresponding method for implementing the apparatus is also provided in accordance with the invention.

14. An apparatus for notifying a user of an incoming cellular telephone call, comprising:
-
a cellular telephone body having at least a back surface;
a first transducer positioned within said cellular telephone body perpendicular to said back surface and adapted to generate a first acoustic field;
a first frequency generator coupled with said first transducer to drive said first transducer to generate said first acoustic field in response to an indication that an incoming cellular telephone call has been received;
a second transducer positioned coaxially to said first transducer and adapted to generate a second acoustic field; and
a second frequency generator coupled with said second transducer to drive said second transducer to generate said second acoustic field in response to an indication that an incoming cellular telephone call has been received, said first and second acoustic fields exhibiting an overlapping portion within the user'"'"'s tissue with said overlapping portion generating a vibrational sensation in the user'"'"'s tissue, thereby indicating to the user that an incoming cellular telephone call has been received; and
whereby said vibrational sensation is generated by a difference of frequency generated in said overlapping portion of said first and second acoustic fields wherein said difference of frequency being more than a threshold difference of frequency so as to generate the vibration sensation at said user'"'"'s tissue. - View Dependent Claims (15, 16, 17, 18, 19, 20)

21. A method for notifying a user of an incoming cellular telephone call, comprising the steps of:
-
providing a first transducer positioned within a cellular telephone body perpendicular to a back surface thereof;
driving said first transducer to generate a first acoustic field in response to an indication that an incoming cellular telephone call has been received;
providing a second transducer positioned coaxially to said first transducer;
driving said second transducer to generate a second acoustic field in response to an indication that an incoming cellular telephone call has been received, said first and second acoustic fields overlapping; and
generating a vibrational sensation in or at the surface of a user'"'"'s tissue when said overlapping fields overlap the user'"'"'s tissue, thereby indicating to a user by a physical sensation on said user'"'"'s tissue, that an incoming cellular telephone call has been received;
whereby said vibrational sensation is generated only in accordance with a difference of frequency generated in said overlapping portion by said first and second acoustic fields wherein said difference of frequency being a substantial difference of frequencies generated from not equal frequencies from the first and second transducers. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28)
