Description

感測壓力及位置之球體Sphere that senses pressure and position

本發明係一種感測壓力及位置之球體，尤指一種可藉由提升訊號雜訊比(SNR)值，進而改善電容觸控性能(Performance)之球體結構。The present invention is a sphere that senses pressure and position, and particularly refers to a sphere structure that can improve the performance of capacitive touch by increasing the signal-to-noise ratio (SNR) value.

第1圖所示的傳統電容觸控球體1，由內向外包括球心13、包覆球心13的接地層11、包覆接地層11的軟性彈性層14、貼附在軟性彈性層14外表面的感測層12，及包覆感測層12的表皮層15。其中，該感測層12與該接地層11電氣連接，用以感測球體1被手指20觸壓的壓力及位置數值。The traditional capacitive touch sphere 1 shown in Figure 1 includes a sphere core 13, a ground layer 11 covering the sphere core 13, and a soft elastic layer 14 covering the ground layer 11 from the inside to the outside, attached to the outside of the soft elastic layer 14.

Wherein, the sensing layer 12 is electrically connected to the ground layer 11 for sensing the pressure and position value of the ball 1 being pressed by the finger 20.

然而，請再參閱第1、2圖所示，該習知之電容觸控球體，都是將Sensor層 (如第1圖中之該等感測層12)做於最外層，而在拿取球體1時容易因接觸而產生一觸摸訊號(Noise)21，而此觸摸訊號21並非真正按壓球體所測得之信號，因此在按壓球體時，訊號雜訊比(SNR)值太小，以導致壓力及位置感測(pressure touch & performance)不佳，容易有誤觸誤報點22的誤判情形。However, please refer to Figures 1 and 2 again. The conventional capacitive touch spheres all use the Sensor layer (such as the sensing layers 12 in Figure 1) as the outermost layer, and the sphere is taken At 1 o'clock, a touch signal (Noise) 21 is easily generated due to contact, and this touch signal 21 is not the signal measured by pressing the sphere. Therefore, when the sphere is pressed, the signal-to-noise ratio (SNR) value is too small, causing pressure And position sensing (pressure touch & performance) is not good, it is easy to falsely touch the false alarm point 22.

為便  貴審查委員能對本發明之目的、形狀、構造裝置特徵及其功效，做更進一步之認識與瞭解，茲舉實施例配合圖式，詳細說明如下：In order to facilitate your reviewer to have a further understanding and understanding of the purpose, shape, features and effects of the structure of the present invention, the examples and diagrams are described in detail as follows:

本發明乃有關一種「壓力及位置感測的球體」，請參閱第3、4圖所示，本發明之壓力及位置感測的球體，其主要係包括有一球體3，係具有一表皮層35；一球心33，係設置於該球體3內部中央；複數片感測層31，係各為長弧形，並同時具有至少6片以上，並分別以相等之間距相互並排或層疊設置於該球心33之外層；一軟性彈性層34，係以海綿、泡棉或其他彈性層之材質包覆該複數片感測層31，其相對該複數片感測層31之另一面則面向該表皮層35；以及一接地層32，係設置介於該軟性彈性層34與該表皮層35之間，以包覆該軟性彈性層34之表面，並與該複數片感測層31電氣連接。The present invention relates to a "pressure and position sensing sphere". Please refer to Figures 3 and 4. The pressure and position sensing sphere of the present invention mainly includes a sphere 3 with a skin layer 35 A sphere center 33, which is set in the center of the interior of the sphere 3; a plurality of sensing layers 31, each of which is a long arc shape, and has at least 6 or more at the same time, and is arranged side by side or stacked on the The outer layer of the spherical center 33; a soft elastic layer 34, which is coated with the plurality of sensing layers 31 with sponge, foam or other elastic layer materials, and the other side of the plurality of sensing layers 31 faces the skin Layer 35; and a ground layer 32, which is disposed between the soft elastic layer 34 and the skin layer 35 to cover the surface of the soft elastic layer 34 and electrically connected to the plurality of sensing layers 31.

藉由上述構件之組成，該接地層32(GND層)設於外側層並包覆複數片感測層31(Sensor層)，可避免拿取球體3時所產生的觸摸訊號(Noise)41，並同時因該複數片感測層31以相等之間距相互並排設置，以避免內部短路而產生誤觸情況，進而提升訊號雜訊比(SNR)值改善電容觸控性能(Performance)。而該球體3可透過該複數片感測層31承受被手指42以電容觸控時之壓力及位置進而取得一信號數值。With the composition of the above components, the ground layer 32 (GND layer) is provided on the outer layer and covers a plurality of sensing layers 31 (Sensor layers), which can avoid the touch signal (Noise) 41 generated when the ball 3 is taken. At the same time, the plurality of sensing layers 31 are arranged side by side at equal intervals to avoid false touches caused by internal short circuits, thereby increasing the signal to noise ratio (SNR) value and improving the capacitive touch performance (Performance). The sphere 3 can receive the pressure and position of the capacitive touch by the finger 42 through the plurality of sensing layers 31 to obtain a signal value.

請參閱第5圖所示，該複數片感測層31係各為長弧形，並同時具有至少6片以上，並分別以相等之間距相互並排設置於該球心33之外層，以避免貼附球體1時不伏貼。Please refer to Figure 5, each of the plurality of sensing layers 31 are long arc-shaped, and have at least 6 or more at the same time, and they are arranged side by side on the outer layer of the spherical center 33 at equal intervals to avoid sticking. It does not fit when attached to the sphere.

在，請參閱第6圖所示，各該感測層31之高度H係大於等於(≧) 各該感測層31之長度L，同時各該感測層31相互之間之間距d係小於等於(≦)各該感測層31之長度L的一半。Please refer to Figure 6, the height H of each sensing layer 31 is greater than or equal to (≧) the length L of each sensing layer 31, and the distance d between each sensing layer 31 is less than It is equal to (≦) half of the length L of each sensing layer 31.

由上述可知，當本發明之球體經由使用者觸碰而移動該球體時，由於感測層被軟性彈性層包覆的關係，並不會因使用者的接觸而產生觸摸訊號(Noise)，而是須由使用者進行按壓觸控時所施予的力量透過軟性彈性層使感測層接收，進而使感測層取得使用者觸控時之壓力及位置的信號數值。It can be seen from the above that when the sphere of the present invention is touched by the user to move the sphere, because the sensing layer is covered by the soft elastic layer, the touch signal (Noise) will not be generated due to the user's contact. The force exerted by the user when pressing and touching is received by the sensing layer through the soft elastic layer, so that the sensing layer can obtain the signal value of the pressure and position when the user is touching.

綜合上所述，本發明之感測壓力及位置之球體，確實具有前所未有之創新構造，其既未見於任何刊物，且市面上亦未見有任何類似的產品，是以，其具有新穎性應無疑慮。另外，本發明所具有之獨特特徵以及功能遠非習用所可比擬，所以其確實比習用更具有其進步性，而符合我國專利法有關發明專利之申請要件之規定，乃依法提起專利申請。In summary, the sphere for sensing pressure and position of the present invention does have an unprecedented innovative structure. It has not been seen in any publications, and there have not been any similar products on the market. Therefore, it has novel applications. No doubt. In addition, the unique features and functions of the present invention are far from comparable with conventional ones, so it is indeed more progressive than conventional ones, and it complies with the requirements of the Chinese Patent Law regarding the requirements for invention patent applications.

以上所述，僅為本發明最佳具體實施例，惟本發明之構造特徵並不侷限於此，任何熟悉該項技藝者在本發明領域內，可輕易思及之變化或修飾，皆可涵蓋在以下本案之專利範圍。The above are only the best specific embodiments of the present invention, but the structural features of the present invention are not limited thereto.
