[0018] An embodiment of the present disclosure (hereinafter also referred to as the present embodiment) will be described in detail with reference to the drawings. Note that the same or corresponding parts in the drawings are designated by the same reference numerals and their description will not be repeated.

[0019] [Vibration module] [A. Overview] First, the configuration of the vibration module according to this embodiment will be described.

[0020] FIG. 1 is a perspective schematic diagram showing the configuration of a vibration module according to this embodiment. As shown in FIG. 1, the vibration module 3 includes a case 1 and a core 2. The core 2 is disposed inside the case 1. The case 1 has a generally rectangular parallelepiped shape.

[0022] [B.Case] FIG. 2 is a schematic plan view showing the configuration of the case. As shown in FIG. 2, case 1 has side surfaces along each side of a rectangle. Specifically, case 1 has a first side surface 11, a second side surface 12, a third side surface 13, and a fourth side surface 14 along each side of a first rectangle D1. When viewed in the front-to-rear direction as shown in FIG. 2, first side surface 11 and third side surface 13 are substantially parallel. Similarly, second side surface 12 and fourth side surface 14 are substantially parallel.

[0023] The rectangle has four corners. Specifically, the first rectangle D1 has a first corner 21, a second corner 22, a third corner 23, and a fourth corner 24. The case 1 of this embodiment has a recess at each of the four corners. Specifically, the case 1 has a first recess 31, a second recess 32, a third recess 33, and a fourth recess 34. The first recess 31, the second recess 32, the third recess 33, and the fourth recess 34 are provided at the first corner 21, the second corner 22, the third corner 23, and the fourth corner 24 of the first rectangle D1, respectively.

[0024] The first recess 31 is formed by a first vertical end portion 31a and a first horizontal end portion 31b connected to the first vertical end portion 31a. The first vertical end portion 31a is connected to each of the first side surface 11 and the front surface 15. The first horizontal end portion 31b is connected to each of the second side surface 12 and the front surface 15. The second recess 32 is formed by a second vertical end portion 32a and a second horizontal end portion 32b connected to the second vertical end portion 32a. The second vertical end portion 32a is connected to each of the second side surface 12 and the front surface 15. The second horizontal end portion 32b is connected to each of the second side surface 12 and the front surface 15.

[0025] The third recess 33 is formed by a third vertical end portion 33a and a third horizontal end portion 33b connected to the third vertical end portion 33a. The third vertical end portion 33a is connected to each of the third side surface 13 and the front surface 15. The third horizontal end portion 33b is connected to each of the fourth side surface 14 and the front surface 15. The fourth recess 34 is formed by a fourth vertical end portion 34a and a fourth horizontal end portion 34b connected to the fourth vertical end portion 34a. The fourth vertical end portion 34a is connected to each of the first side surface 11 and the front surface 15. The fourth horizontal end portion 34b is connected to each of the fourth side surface 14 and the front surface 15.

[0026] In the above description, the case 1 is described as having a recess at each of the four rectangular corners, but the vibration module 3 according to this embodiment is not limited to this. Specifically, it is sufficient that the case 1 has a recess at at least one of the four rectangular corners. For example, the case 1 may have the first recess 31, but may not have the second recess 32, the third recess 33, or the fourth recess 34.

[0027] Case 1 may have recesses in at least two of its four corners that are symmetrical left-right, top-bottom, or point-symmetric. For example, case 1 may have first recess 31 and second recess 32, but not third recess 33 and fourth recess 34. For example, case 1 may have first recess 31 and second recess 32, but not third recess 33 and fourth recess 34. For example, case 1 may have first recess 31 and third recess 33, but not second recess 32 and fourth recess 34.

[0028] 1 and 2, the recesses may extend from the front surface 15 to the rear surface 16. In the vibration module 3 according to this embodiment, the first recess 31, the second recess 32, the third recess 33, and the fourth recess 34 each extend from the front surface 15 to the rear surface 16. Of the first recess 31, the second recess 32, the third recess 33, and the fourth recess 34, at least one recess may extend from the front surface 15 to the rear surface 16, and the other recesses may not extend from the front surface 15 to the rear surface 16.

[0029] As shown in FIG. 2, the distance between the second side surface 12 and the fourth side surface 14 in the left-right direction is defined as a first case distance A1. The distance between the first side surface 11 and the third side surface 13 in the up-down direction is defined as a second case distance A2. In the vibration module 3 according to this embodiment, the first case distance A1 is greater than the second case distance A2. The distance between the second vertical end portion 32a and the third vertical end portion 33a in the left-right direction is defined as a third case distance A3. The distance between the third horizontal end portion 33b and the fourth horizontal end portion 34b in the up-down direction is defined as a fourth case distance A4. In the vibration module 3 according to this embodiment, the third case distance A3 is greater than the fourth case distance A4.

[0030] [C. Core] FIG. 3 is a partial cross-sectional schematic view taken along line III-III in FIG. 1. The cross-sectional view shown in FIG. 3 is parallel to both the left-right direction and the up-down direction. As shown in FIG. 3, core 2 has core recesses at positions corresponding to the recesses of case 1. Specifically, core 2 has a first core recess 51, a second core recess 52, a third core recess 53, and a fourth core recess 54. The first core recess 51 is located at a position corresponding to first recess 31. The second core recess 52 is located at a position corresponding to second recess 32. The third core recess 53 is located at a position corresponding to third recess 33. The fourth core recess 54 is located at a position corresponding to fourth recess 34.

[0031] Core 2 has a first core side surface 41, a second core side surface 42, a third core side surface 43, and a fourth core side surface 44. Third core side surface 43 is opposite first core side surface 41. Fourth core side surface 44 is opposite second core side surface 42.

[0032] The first core recess 51 is formed by a first core vertical end portion 51a and a first core horizontal end portion 51b continuing to the first core vertical end portion 51a. The first core vertical end portion 51a continues to the first core side surface 41. The first core horizontal end portion 51b continues to the second core side surface 42. The second core recess 52 is formed by a second core vertical end portion 52a and a second core horizontal end portion 52b continuing to the second core vertical end portion 52a. The second core vertical end portion 52a continues to the third core side surface 43. The second core horizontal end portion 52b continues to the second core side surface 42.

[0033] The third core recess 53 is formed by a third core vertical end portion 53a and a third core horizontal end portion 53b that continues to the third core vertical end portion 53a. The third core vertical end portion 53a continues to the third core side surface 43. The third core horizontal end portion 53b continues to the fourth core side surface 44. The fourth core recess 54 is formed by a fourth core vertical end portion 54a and a fourth core horizontal end portion 54b that continues to the fourth core vertical end portion 54a. The fourth core vertical end portion 54a continues to the first core side surface 41. The fourth core horizontal end portion 54b continues to the fourth core side surface 44.

[0034] The first core recess 51 is disposed more inward than the first recess 31. Specifically, the first core vertical end 51a is positioned more inward than the first vertical end 31a in the second direction R2. The first core horizontal end 51b is positioned more inward than the first horizontal end 31b in the fourth direction R4. The second core recess 52 is disposed more inward than the second recess 32. Specifically, the second core vertical end 52a is positioned more inward than the second vertical end 32a in the second direction R2. The second core horizontal end 52b is positioned more inward than the second horizontal end 32b in the third direction R3.

[0035] The third core recess 53 is disposed more inward than the third recess 33. Specifically, the third core vertical end portion 53a is positioned more inward in the first direction R1 than the third vertical end portion 33a. The third core horizontal end portion 53b is positioned more inward in the third direction R3 than the third horizontal end portion 33b. The fourth core recess 54 is disposed more inward than the fourth recess 34. Specifically, the fourth core vertical end portion 54a is positioned more inward in the first direction R1 than the fourth vertical end portion 34a. The fourth core horizontal end portion 54b is positioned more inward in the fourth direction R4 than the fourth horizontal end portion 34b.

[0036] The core 2 vibrates reciprocally in a linear manner. Specifically, the core 2 reciprocates in the left-right direction. The plane in which the core 2 reciprocates is perpendicular to the front-rear direction. In other words, the cross-sectional schematic diagram shown in FIG. 3 is a view from a direction in which the reciprocating motion of the core 2 is viewed from above.

[0037] According to the vibration module 3 of this embodiment, the core 2 is provided with a core recess at a position corresponding to the recess in the case 1. This prevents the core 2 from interfering with the housing or other components, while maintaining the volume of the core 2 and suppressing a decrease in the strength of vibration due to the size of the vibrator and / or the maximum amplitude.

[0038] The case 1 has a first inner wall surface 61, a second inner wall surface 62, a third inner wall surface 63, and a fourth inner wall surface 64. The first inner wall surface 61 faces the first core side surface 41. The second inner wall surface 62 faces the second core side surface 42. The third inner wall surface 63 faces the third core side surface 43. The fourth inner wall surface 64 faces the fourth core side surface 44. The distance between the second inner wall surface 62 and the second core side surface 42 in the left-right direction is greater than the distance between the first inner wall surface 61 and the first core side surface 41 in the up-down direction. The distance between the fourth inner wall surface 64 and the fourth core side surface 44 in the left-right direction is greater than the distance between the third inner wall surface 63 and the third core side surface 43 in the up-down direction. This ensures a space for the core 2 to reciprocate in the left-right direction.

[0039] The distance between the second core side surface 42 and the fourth core side surface 44 in the left-right direction is defined as a first core distance B1. The distance between the first core side surface 41 and the third core side surface 43 in the up-down direction is defined as a second core distance B2. The first core distance B1 is larger than the second core distance B2. The distance between the second core vertical end portion 52a and the third core vertical end portion 53a in the left-right direction is defined as a third core distance B3. The distance between the third core horizontal end portion 53b and the fourth core horizontal end portion 54b in the up-down direction is defined as a fourth core distance B4. The third core distance B3 is larger than the fourth core distance B4.

[0040] 3, the third case distance A3 is greater than the third core distance B3 and less than the first core distance B1. The fourth case distance A4 is greater than the fourth core distance B4 and less than the second core distance B2. This allows the volume of the core 2 to be increased without the core 2 protruding from the case 1.

[0041] 1 and 3, the first recess 31, the second recess 32, the third recess 33, and the fourth recess 34 are open. Specifically, the first vertical end 31a is continuous with the first inner wall surface 61. The first horizontal end 31b is continuous with the second inner wall surface 62. The second vertical end 32a is continuous with the third inner wall surface 63. The second horizontal end 32b is continuous with the second inner wall surface 62. The third vertical end 33a is continuous with the third inner wall surface 63. The third horizontal end 33b is continuous with the fourth inner wall surface 64. The fourth vertical end 34a is continuous with the first inner wall surface 61. The fourth horizontal end 34b is continuous with the fourth inner wall surface 64.

[0042] Although the above description has been given of a case where all four recesses are open, the vibration module 3 according to this embodiment is not limited to this. Specifically, one of the four recesses may be open and the remaining three recesses may not be open. In another aspect, two of the four recesses may be open and the remaining two recesses may not be open. In yet another aspect, three of the four recesses may be open and the remaining one recess may not be open.

[0043] According to the vibration module 3 of this embodiment, at least a portion of the recess is open. This allows air to flow in and out of the case 1 through the opening, allowing heat generated by the core 2 to escape to the outside of the case 1. This improves the heat dissipation performance of the vibration module 3.

[0044] FIG. 4 is a partial cross-sectional schematic view taken along line IV-IV in FIG. 3. As shown in FIG. 4, the vibration module 3 has a vibration mechanism 7. The vibration mechanism 7 has a core 2 and a coil 6. The core 2 is composed of, for example, a yoke 4 and a magnet 5. The core 2 moves relative to the coil 6. When an alternating current is applied to the coil 6, the core 2 performs a reciprocating linear motion. In this embodiment, the core 2 performs a reciprocating linear motion in the left-right direction. The coil 6 is stationary. The vibration mechanism 7 is, for example, a linear resonance actuator or a voice coil motor.

[0045] The magnet 5 is spaced apart from the coil 6. The magnet 5 is disposed opposite the coil 6. According to the vibration module 3 of this embodiment, the magnet 5 is provided, for example, on both sides of the coil 6 in the front-rear direction. The yoke 4 is provided in contact with the magnet 5. As shown in FIG. 4 , when viewed in the left-right direction, the yoke 4 is provided so as to surround the coil 6. The first core side surface 41 and the second core side surface 42 may be formed by the yoke 4. Similarly, the third core side surface 43 and the fourth core side surface 44 may be formed by the yoke 4.

[0046] The core 2 is only required to be composed of at least the yoke 4 and the magnet 5, and may include members other than the yoke 4 and the magnet 5.

[0047] [D. Magnet] FIG. 5 is a schematic plan view showing the configuration of the magnet. As shown in FIG. 5, in this embodiment, the magnet 5 is rectangular when viewed from a direction in which the reciprocating motion of the core 2 is viewed from above. The magnet 5 may be rectangular or square. The length of the magnet 5 in the left-right direction is defined as a first magnet length C1. The length of the magnet 5 in the up-down direction is defined as a second magnet length C2. The first magnet length C1 may be greater than the second magnet length C2.

[0048] [E. York] 6 is a plan view schematic diagram showing the configuration of the yoke. As shown in FIG. 6, when viewed from a direction in which the reciprocating motion of the core 2 is viewed from above, the yoke 4 may have a shape in which recesses are provided at the four corners of a second rectangle D2. Specifically, the yoke 4 is formed with a first core recess 51, a second core recess 52, a third core recess 53, and a fourth core recess 54. According to the vibration module 3 according to this embodiment, when viewed in the front-rear direction, the shape of the yoke 4 is substantially the same as the shape of the core 2.

[0049] 6, when viewed from a direction that reflects the reciprocating motion of the core 2 in a plan view, the shape of the core 2 may be symmetrical both vertically and horizontally. Specifically, the lengths of the first core vertical end portion 51a, the second core vertical end portion 52a, the third core vertical end portion 53a, and the fourth core vertical end portion 54a are substantially the same. The lengths of the first core horizontal end portion 51b, the second core horizontal end portion 52b, the third core horizontal end portion 53b, and the fourth core horizontal end portion 54b are substantially the same.

[0050] In the vibration module 3 according to this embodiment, the core 2 is composed of at least the yoke 4 and the magnet 5. When viewed from a direction in which the reciprocating motion of the core 2 is viewed from above, the vibration module 3 can be easily manufactured by forming a core recess in the yoke 4 and making the magnet 5 rectangular.

[0051] According to the vibration module 3 of this embodiment, the shape of the core 2 is symmetrical both vertically and horizontally when viewed from a plane in the direction of the reciprocating motion of the core 2. This not only prevents a decrease in vibration strength, but also prevents unintended vibrations caused by weight imbalance.

[0052] [F. Variations] Next, the configuration of a modified example of the vibration module 3 will be described. When viewed from a direction in which the reciprocating motion of the core 2 is viewed from above, the shape of the core 2 is vertically symmetrical and left-right symmetrical, and the shape of the case 1 does not have to be vertically symmetrical and left-right symmetrical. For example, the core 2 may be formed with a first core recess 51, a second core recess 52, a third core recess 53, and a fourth core recess 54, and the case 1 may be formed with only the first recess 31, without the second recess 32, the third recess 33, and the fourth recess 34.

[0053] In the above, the magnets 5 are provided on both sides of the coil 6, but this is not limited to the above configuration. There may be only one magnet 5. In this case, the magnet 5 may be provided on only one side of the coil 6 in the front-rear direction.

[0054] In the above, at least one of the recesses formed in the case 1 is open, but this is not limited to the above configuration. For example, all four recesses do not have to be open.

[0055] [controller] Next, the configuration of the controller according to this embodiment will be described. FIG. 7 is a partial cross-sectional schematic diagram showing the configuration of the controller according to this embodiment. As shown in FIG. 7, the controller 100 has a housing 110, a plurality of operation buttons 102, an operation stick 101, and a vibration module 3. The housing 110 has at least a portion that is rounded 113. The housing 110 of the controller 100 according to this embodiment has a housing front surface 114, a housing top surface 111, a housing bottom surface 112, the rounded portion 113, and a linear portion 115. The plurality of operation buttons 102 and the operation stick 101 are arranged on the housing front surface 114.

[0056] The housing top surface 111 is continuous with the housing front surface 114. The housing bottom surface 112 is continuous with the housing front surface 114. The housing bottom surface 112 is located opposite the housing top surface 111. The rounded portion 113 is continuous with the housing front surface 114. The rounded portion 113 has a rounded inner wall surface 113b and a rounded outer wall surface 113a. The rounded outer wall surface 113a connects the housing top surface 111 and the housing bottom surface 112. The linear portion 115 is continuous with the rounded portion 113. The linear portion 115 forms the housing bottom surface 112.

[0057] The vibration module 3 included in the controller 100 according to this embodiment is the same as the vibration module 3 according to this embodiment. The vibration module 3 is disposed in the housing 110. The vibration module 3 is disposed so as to be in contact with the rounded inner wall surface 113b of the rounded portion 113. In a front view, the rounded inner wall surface 113b may be an arc-shaped surface, an elliptical arc-shaped surface, or the like. A first recess 31 provided in the case 1 of the vibration module 3 is disposed in the rounded portion 113. Specifically, the first recess 31 is disposed so as to face the rounded inner wall surface 113b. The second side surface 12 of the case 1 faces the rounded inner wall surface 113b. The third side surface 13 of the case 1 faces the inner wall surface of the linear portion 115.

[0058] The vibration module 3 has the notches 31 at the corners, which makes it possible to avoid interference with the rounded wall surface 113b. In other words, the volume and vibration amount of the vibration module 3 (core 2) can be increased without interfering with the rounded wall surface 113b.

[0059] In the above, the case where housing 110 of controller 100 has rounded portion 113 and linear portion 115 has been described, but housing 110 of controller 100 does not have to have linear portion 115. Specifically, the shape of controller 100 may be a perfect circle or an oval when viewed from the front.

[0060] The vibration module 3 according to this embodiment has a case 1 and a core 2. The core 2 is disposed inside the case 1. The case 1 has a recess in at least one of its four rectangular corners. This allows the vibration module 3 to be disposed while avoiding interference with the housing 110 or other components. Furthermore, by providing recesses in at least two of the corners of the case 1 that are bilaterally symmetrical, vertically symmetrical, or point-symmetrical, the same module can be used in different devices (such as controllers) while avoiding interference with the housing or other components.

[0061] [Controller Set] Next, the configuration of a controller set according to this embodiment will be described. Figure 8 is a partial cross-sectional view showing the configuration of a controller set 300 according to this embodiment. As shown in Figure 8, the controller set 300 according to this embodiment has a first controller 100 and a second controller 200. The first controller 100 is the same as the controller 100 according to this embodiment.

[0062] 8, the second controller 200 has a second housing 210, a plurality of second operation buttons 202, a second operation stick 201, and a vibration module 3. The second housing 210 has a second rounded portion 123.

[0063] The vibration module 3 of the second controller 200 is the same as the vibration module 3 according to this embodiment. The vibration module 3 is disposed in the second housing 210. In front view, the inner wall surface of the second rounded portion 123 is arc-shaped. The second recess 32 provided in the case 1 of the vibration module 3 is disposed in the rounded portion 113. Specifically, the second recess 32 is disposed so as to face the inner wall surface of the rounded portion 113.

[0064] 8, the outer shape of the controller set 300 is line-symmetrical with respect to an imaginary line. Specifically, the outer shape of the first controller 100 and the outer shape of the second controller 200 are line-symmetrical with respect to the imaginary line X. The first operation stick 101 and the second operation button 202 are arranged in line-symmetrical positions with respect to the imaginary line X. Similarly, the second operation stick 201 and the first operation button 102 are arranged in line-symmetrical positions with respect to the imaginary line X.

[0065] According to the vibration module 3 of this embodiment, recesses may be provided in at least two of the four corners of the case 1 that are symmetrical left-right, up-down, or point-symmetric.
