[0020]
Next, an electrical configuration of the XY biaxial geomagnetic sensor 110 is shown in FIG. In the figure, an XY biaxial geomagnetic sensor 110 has a GMR (Giant Magneto Resistive) circuit 1110 and a voltage / magnetic field conversion circuit 1111.
The GMR circuit 1110 includes a constant current bias circuit 1112, an X-axis GMR element 1113 for detecting the geomagnetic X component, and a Y-axis GMR element 1114 for detecting the geomagnetic Y component.
[0021]
The constant current bias circuit 1112 receives the ON signal and supplies a constant current to the X-axis GMR element 1113 and the Y-axis GMR element 1114. The X-axis GMR element 1113 and the Y-axis GMR element 1114 are elements whose resistance values change in accordance with changes in magnetism, and a change in magnetism is detected as a change in voltage by flowing a constant current through these elements as a bias.

The voltage / magnetic field conversion circuit 1111 has a function of converting the voltage output from the GMR circuit 1110 into a magnetic field and outputting the magnetic field.
[0022]
Next, the operation at the time of orientation display in the mobile phone device according to the embodiment of the present invention will be described with reference to the flowchart of FIG. In this figure, when the XY biaxial geomagnetic sensor 110 is turned on (step 200), a constant current is supplied from the constant current bias circuit 1112 in the XY biaxial geomagnetic sensor 110 to the X axis GMR element 1113 and the Y axis GMR element 1114. The voltage output from the X-axis GMR element 1113 and the Y-axis GMR element 1114 is converted into an X component and a Y component of the magnetic field by the geomagnetism by the voltage / magnetic field conversion circuit 1111 and output.
[0023]
Next, the X component and Y component of the magnetic field generated by the geomagnetism output from the XY biaxial geomagnetic sensor 110 are captured (step 201), and offset correction is performed on the X component and Y component of the captured magnetic field (step 202). With reference to the magnetic field / orientation conversion table stored in the ROM 102, orientation data corresponding to the detection output of the XY biaxial geomagnetic sensor 110 is acquired (step 203). Further, based on the obtained azimuth data, the azimuth of the mobile phone device 1 is displayed on the display unit 118 as shown in FIG. 4 (step 204).
[0024]
Next, referring to the azimuth / sound source parameter conversion table from the ROM 102, the sound source parameter corresponding to the azimuth data obtained in step 202 is obtained (step 205), and the sound source in the music reproducing unit 116 is driven (step 206). Thus, the azimuth is notified not only on the display unit in step 204 but also on the scale by the sound source in the music reproduction unit 116. After the orientation of the mobile phone device 1 is notified by display and scale, an OFF signal is output to the XY biaxial geomagnetic sensor 110, and the orientation display operation is terminated (step 207).

In this embodiment, as shown in the figure, the azimuth is represented by 12 directions, and 12 scales (represented by symbols A to G, #, and ♭) are assigned to each direction. On the display unit 118 of the mobile phone device 1, as shown in FIG. 5, a key to which a desired tone length is assigned in the operation input unit 106 is operated in a state where N (north) of the direction hand indicates a predetermined pitch. By doing so, a note is input. At this time, the octave is determined based on the number of rotations of the mobile phone device 1 in the clockwise direction (octave up) and the number of rotations in the counterclockwise direction (octave down).
[0026]
The rotational speed is grasped by monitoring the sensor output from when the geomagnetic sensor is turned on. Note that the octave may be specified by assigning a specific key in the operation input unit 106 separately.
The rest is input by selecting a rest input mode with a predetermined key and operating a key to which each tone length is assigned. As described above, the keys for the sound length input and the rest length input are shared.

The voltage output from the X-axis GMR element 1113 and the Y-axis GMR element 1114 is converted into an X component and a Y component of the magnetic field by the geomagnetism by the voltage / magnetic field conversion circuit 1111 and output.
[0028]
Next, the X and Y components of the magnetic field generated by the geomagnetism output from the XY biaxial geomagnetic sensor 110 are captured (step 301), and the X and Y components of the captured magnetic field are offset corrected (step 302). With reference to the magnetic field / orientation conversion table stored in the ROM 102, orientation data corresponding to the detection output of the XY biaxial geomagnetic sensor 110 is acquired (step 303). Further, based on the obtained azimuth data, as shown in FIG. 5, the azimuth of the cellular phone device 1 (background indicates a pitch) is displayed on the display unit 118 (step 304).
[0029]
Next, based on the detection output of the XY biaxial geomagnetic sensor 110, the octave is determined from the rotation direction and the rotation speed of the mobile phone device 1, and stored in a predetermined memory area of the RAM 104 (step 305).
Next, it is determined whether or not a mode designation key has been input (step 306). If the determination in step 306 is negative, the process proceeds to step 308.
[0030]
If the determination in step 306 is affirmative, the state is switched to a state where note input and rest input are possible (step 307), and then in step 308 whether or not the sound length (rest length) key is operated. Is determined. If the determination in step 308 is negative, the process proceeds to step 312.
If the determination in step 308 is affirmative, it is determined whether or not it is a note input mode, that is, whether or not the # key has been operated (step 309).
[0031]
When the note input mode is set, the pitch is obtained by referring to the azimuth / pitch conversion table stored in the ROM 102, and the octave and pitch data are stored in a predetermined area of the RAM 104 as note data. Store (step 310).
On the other hand, if the determination in step 309 is negative, that is, if the * key is operated and the rest input mode is set, the rest length that has been input is stored in a predetermined area of the RAM 104 as rest data. Store (step 311).
[0032]
Next, at step 312, it is determined whether or not the composition has been completed. If it is determined in step 312 that the composition has not ended, the process returns to 301 and the above-described processing is repeated.
If it is determined in step 312 that the composition has ended, an OFF signal is output to the XY biaxial geomagnetic sensor 110, and this operation is ended (step 313).
