Voice output unit 13 exports sound according to the control information inputted by processing unit 12, thus can export the sound corresponding with the operating parameter of input equipment.
Below, the method for the operating parameter being determined input equipment by processing unit according to magnetic intensity vector is illustrated.
Here, when user utilizes input equipment to perform music, input equipment is brandished around electronic equipment or knocks.Described input equipment can be a pen embedding permanent magnet, or the device such as finger ring or baton of other embedding permanent magnet.Preferably, described input equipment is the capacitance pen being embedded with permanent magnet, and the direction of magnetization of described permanent magnet is the axis direction of pen.
The first, the method in the operator region determining input equipment according to magnetic intensity vector is described.
According to two or more preposition, the perimeter of electronic equipment 1 is divided into multiple subregion.Processing unit 12 carries out demarcation process, namely based on the size of the intended component in the magnetic intensity vector produced by Magnetic Sensor 11 when input equipment being placed on preposition, the magnitude range of the intended component in the magnetic intensity vector corresponding respectively with described multiple subregion is obtained.
Fig. 2 is the schematic diagram illustrating setting four precalculated positions (i.e. the upper left corner of the housing of electronic equipment 1, the lower left corner, the lower right corner, the upper right corner) and according to these four precalculated positions, the perimeter of electronic equipment 1 is divided into four sub regions (namely going up region, lower area, left region, right region).In addition, the number in precalculated position, position are only illustrate, and are not limited to the method shown in Fig. 2.
In the situation shown in fig. 2, processing unit 12 obtains the size of the intended component of the magnetic intensity vector when the upper left corner of housing input equipment being placed on electronic equipment 1, the lower left corner, the lower right corner, the upper right corner respectively, and the size of intended component according to obtained four magnetic intensity vectors, determine the magnitude range of the intended component of the magnetic intensity vector corresponding respectively with four sub regions.

As mentioned above, when carrying out demarcation process electronic equipment 1 is lain in surface level, the intended component of magnetic intensity vector is X-axis component and Y-axis component.But according to the attitude of the electronic equipment 1 undertaken by processing unit 12 when demarcating process, the result of demarcating process is different.Such as, when electronic equipment 1 being placed on the plane determined by X-axis, Z axis, the scope corresponding respectively with described multiple subregion is the magnitude range (namely intended component is X-axis component and Y-axis component) of X-axis component in magnetic intensity vector and Z axis component.Therefore, in the process using electronic equipment 1, if the attitudes vibration of electronic equipment 1, then change the magnitude range of the intended component in the magnetic field intensity information corresponding respectively with multiple subregion according to the attitude of electronic equipment 1.
Particularly, electronic equipment 1 also comprises acceleration transducer.The configuration of this acceleration transducer obtains the attitude of electronic equipment 1.Processing unit 12, according to the attitude of the electronic equipment 1 after change, adjusts the magnitude range of the intended component in the demarcated magnetic field intensity information corresponding respectively with multiple subregion.In addition, the parts for the attitude obtaining electronic equipment 1 are not limited to acceleration transducer, such as, also can be obtained the attitude of electronic equipment 1 by parts such as gyroscopes.
Utilize input equipment when particular sub-area is brandished or knock when user, the size of the intended component of the magnetic intensity vector obtained by Magnetic Sensor 11 falls into the magnitude range of the intended component corresponding with this particular sub-area.
Therefore, the result that processing unit 12 processes according to above-mentioned demarcation, based on the size of the intended component in the magnetic intensity vector produced by Magnetic Sensor 11, determine the corresponding subregion corresponding with the scope that the size of this intended component falls into, thus corresponding subregion is defined as the operator region of input equipment.

Processing unit 12, based on the period of change of the magnetic intensity vector obtained by Magnetic Sensor 11, determines the operation rhythm of input equipment.
Fig. 4 is illustrated in the oscillogram that input equipment carries out each component of magnetic intensity vector when knocking motion.As shown in Figure 4, each component of magnetic intensity vector according to the rhythm knocking motion, again to trough from trough to crest.
Particularly, first processing unit 12 can carry out high-pass filtering, using intended component large for high frequency power as handling object to each component of magnetic intensity vector.In the case of fig. 5, X-axis component can be chosen as handling object.And then processing unit 12 using the crest of X-axis component curve as the time point knocked, can calculate the time point of the crest of X-axis component curve, using the period of change of the time interval of adjacent crest as magnetic intensity vector successively.
In addition, the method for the period of change of calculating magnetic field strength vector is not limited to this, also can apply other method.Such as, also the period of change of the time interval as magnetic intensity vector of adjacent trough can be calculated, also can carry out process to obtain period of change to intended component in a frequency domain, process can certainly be carried out to obtain period of change to the curve of multiple components of magnetic intensity vector.
And then processing unit 12 produces and makes voice output unit 13 export the control information of sound with the sound rhythm corresponding with operation rhythm.
3rd, the method carrying out determination operation dynamics according to magnetic intensity vector is described.
When the operating force of input equipment is large, magnetic intensity vector is presented as the difference of crest value and trough value becomes large and trough shortened to time interval of crest.On the contrary, when the operating force of input equipment is little, magnetic intensity vector is presented as the difference of crest value and trough value diminishes and trough is elongated to the time interval of crest.That is, the period of change of operating force magnetic intensity vector is relevant with amplitude of variation, is directly proportional particularly to the amplitude of variation of magnetic intensity vector, and is inversely proportional to the period of change of magnetic intensity vector.
Therefore, processing unit 12, based on the period of change of magnetic intensity vector and amplitude of variation, determines the operating force of input equipment.
Particularly, first processing unit 12 can carry out high-pass filtering, using intended component large for high frequency power as handling object to each component of magnetic intensity vector.In the case of fig. 5, X-axis component can be chosen as handling object.And then, processing unit 12 can calculate the difference of adjacent crest value and trough value, thus as the amplitude of variation of magnetic intensity vector, and calculate the period of change of the time interval as magnetic intensity vector of adjacent trough and crest, finally utilize this period of change divided by the business of this amplitude of variation as operating force.
In addition, the method for the operating force of calculating magnetic field strength vector is not limited to this, also can apply other method.Such as, also the period of change of difference as magnetic intensity vector of adjacent crest value and trough value can only be calculated, also can carry out process to obtain period of change to intended component in a frequency domain, process can certainly be carried out to obtain period of change to the curve of multiple components of magnetic intensity vector.
And then processing unit 12 produces and makes voice output unit 13 export the control information of sound with the volume corresponding with operating force.
