[0041 ] 实施例二 [0041] Second Embodiment

[0042]为了配合内部芯片的运作,本实施例将实施例一中的霍尔IC130进行了优选设计,实施例一中公开的技术方案不在描述,实施例一公开的技术方案也属于本实施例。 [0042] In order to meet the operational chip, the Hall IC130 Example Example of the present embodiment will be a preferred design, disclosed in the first embodiment are not described aspect, an embodiment of the disclosed embodiments also belong to the technical solution of the present embodiment .

[0043]如图5所示,为清楚的显示本实施例与实施例一的区别技术特征,该图中仅示出了磁环140和霍尔ICl 30,具体而言:所述霍尔ICl 30包括两个霍尔元件,即主元件A和辅元件B(可任意指定其中一个为主元件A,则另一个为辅元件B),所述主元件A和所述辅元件B位于同一圆上的不同位置,所述圆与所述磁环140为同心圆,使得所述主元件A和所述辅元件B相对于磁环140的旋转的角速度、线速度都相同,提高所述输出电信号的规律性和可控性。 [0043] As shown in FIG 5, the present embodiment is clearly shown embodiment differs from the technical features of one embodiment, the drawing shows only 30 ICl ring 140 and Hall, specifically: the Hall ICl 30 comprises two Hall elements, i.e. the primary and secondary element a element B (can be specified in which a main element a, element B is another supplement), said main element and said auxiliary element a is located in the same circle B different positions on the circle concentric with the magnet ring 140, so that the main element a and the element B with respect to the secondary angular velocity of the ring 140, the same line speed, increase the output regularity and control signals. 并且,主元件A和辅元件B在其所在圆上所呈的圆心角α,优选设置为相邻的两个所述磁极在其圆环上所呈的圆心角β的3/4,据此,可实现当主元件A表面上的磁力下降(或升高)时,辅元件B表面上的磁力为下降和升高交替发生,即确保不会发生主元件A表面上的磁力变化与辅元件B表面上的磁力变化始终保持同步同向或者反向,若保持同步同向或者反向的磁力变化,则对于霍尔IC130的相对偏转方向的判定较为复杂且相对不准确。 Further, the primary and secondary element A in element B of the circle on which they form a central angle [alpha], is preferably disposed adjacent the poles of two annular rings which form in the central angle β is 3/4, whereby when, can be realized when the magnetic element on the surface of the main a decrease (or increase), on the surface of the secondary magnetic member B is increased and decreased alternately occur, i.e., to ensure that changes to the secondary magnetic member B on the main surface of the element a does not occur magnetic force change on the surface are always synchronized with the reverse direction or if the sync counter or the same magnetic force to change the yaw direction relative to the Hall IC130 determined more complicated and relatively inaccurate.

[0047] 结合图5和图6:当磁环140沿逆时针旋转时,主元件A位于N极磁场内且逐渐远离N极,主元件A表面上的磁力下降,主元件A被触发并产生一个脉冲,此时辅元件B位于S极磁场内并逐渐远离S极,主元件A检测到辅元件B表面上的磁力降低,即可表示为霍尔IC130相对磁环140顺时针旋转(图示右转),霍尔ICl 30的内部电路据此输出低电平。 [0047] in conjunction with FIGS. 5 and 6: when the rotating ring 140 rotates counterclockwise, the main element A is located in the N pole magnetic field and progressively away from the N-pole, the magnetic force on the surface of the main element A drop A main element is triggered and produces a pulse, then the secondary element is located in the S pole magnetic field B and moving away from the S-pole, the magnetic force of the main element a is detected on the surface of the auxiliary member B is reduced, can be expressed as a relative magnetic Hall IC130 140 rotates clockwise (shown turn right), Hall ICl internal circuit 30 outputs a low level accordingly.

[0048] 结合图5和图7:当磁环140沿顺时针旋转时,主元件A位于N极磁场内且逐渐远离N极,主元件A表面上的磁力下降,主元件A被触发并产生一个脉冲,此时辅元件B位于S极磁场内并逐渐靠近S极,主元件A检测到辅元件B表面上的磁力增加,即可表示为霍尔IC130相对磁环140逆时针旋转(图示左转),霍尔ICl 30的内部电路据此输出高电平。 [0048] in conjunction with FIGS. 5 and 7: When the rotating magnet ring 140 clockwise, the main element A is located in the N pole magnetic field and progressively away from the N-pole, the magnetic force on the surface of the main element A drop A main element is triggered and produces a pulse, then the secondary element is located in the S pole magnetic field B and S pole gradually approaches the main element a detects an increase in the magnetic force on the surface of the auxiliary element B, can be expressed as IC130 Hall ring 140 is rotated counterclockwise opposite (shown left), Hall ICl internal circuit 30 outputs a high level accordingly.

[0049] 3、霍尔IC130将产生的所述脉冲信号以及对应的高电平或者低电平输送至所述内部芯片。 [0049] 3, the pulse signal corresponding to a high level, and the resulting Hall IC130 or low fed to the chip.

[0050]内部芯片即可依据霍尔IC130所发送的脉冲信号和高电平调高衰减实现音量降低,或者依据霍尔IC130所发送的脉冲信号和低电平调低数衰减实现音量升高。 [0050] The chip according to a high level and a signal pulse transmitted Hall IC130 attenuation increase with volume reduction, or according to a pulse signal from the Hall IC130 transmitted down the number of low attenuation and increase the volume achieved.
