Accordingly, the elastic body 17 is configured to be fixed in a state of being sandwiched between the lower end surface of the middle frame 8 and the inner surface of the back cover 6. For this reason, the position of the diaphragm 16 is regulated so as not to be pushed into the wristwatch case 1 by the lower end surface of the middle frame 8 even if the diaphragm 16 is pushed into the wristwatch case 1 from below.

  Further, as shown in FIG. 1, the diaphragm 16 is formed with a thickness that is substantially the same as the thickness of the back cover 6, but preferably a little thinner than the thickness of the back cover 6. desirable. Thus, the diaphragm 16 is configured such that the outer peripheral edge of the diaphragm 16 does not protrude toward the back side of the back cover 6 when it is disposed in the opening 15 of the back cover 6. In addition, a waterproof ring 6 a for waterproofing between the case body 2 and the back cover 6 of the watch case 1 is integrally formed on the outer peripheral portion of the elastic body 17.

  The vibration motor 18 mounted on the diaphragm 16 includes a motor portion 18a, a pair of eccentric rotation portions 18b, and a circuit portion 18c, as shown in FIGS. 1 to 4, and the motor portion 18a is a pair of eccentric rotations. By rotating the part 18b eccentrically, it is configured to generate vibration. The vibration motor 18 is configured to be attached to a motor holding portion 21 formed integrally with the vibration plate 16.

  The motor holding part 21 includes synthetic resin and is integrally formed with the diaphragm 16 by insert molding as shown in FIGS. That is, the motor holding portion 21 includes a main body portion 21a that holds the motor portion 18a of the vibration motor 18 and a fixing portion 21b that is embedded and fixed in the diaphragm 16, and these are integrated with a synthetic resin. Is formed.

  2 to 4, the main body portion 21a is formed in a substantially box shape with its upper side and both sides open, and a motor portion 18a is disposed therein, and in this state, the pair of eccentric rotating portions 18b It is comprised so that it may protrude outside the both sides of the main-body part 21a. The fixing portion 21b is exposed on the inner surface of the diaphragm 16 in a state where a part of the fixing portion 21b is embedded in the mounting hole portion 22 provided in the diaphragm 16, and the exposed portion is formed integrally with the main body portion 21a. ing.

  In this case, as shown in FIG. 4, the attachment hole portion 22 of the diaphragm 16 is formed so that the hole width at the position located on the inner surface of the diaphragm 16 is narrower than the inner hole width in the diaphragm 16. The fixing portion 21b is formed in a state of being embedded in the mounting hole portion 22 of the diaphragm 16 by insert molding together with the main body portion 21a. As a result, the fixed portion 21 b is formed integrally with the diaphragm 16 so as not to be detached from the diaphragm 16.

  As shown in FIGS. 2 to 4, the vibration motor 18 has the motor portion 18 a disposed in the main body portion 21 a by the presser fitting 23 in a state where the motor portion 18 a is disposed in the main body portion 21 a of the motor holding portion 21. It is comprised so that it may be pressed and fixed to. The presser fitting 23 is made of a metal plate such as stainless steel, and a pair of engagement pieces 23 a are provided on both sides along the axial direction of the vibration motor 18 by being bent downward.

  Accordingly, as shown in FIGS. 2 to 4, the presser fitting 23 is arranged on the main body 21 a of the motor holding portion 21 where the motor 18 a is arranged, and the engagement pieces 23 a on both sides are arranged on the main body 21 a. By being engaged with a hook portion 24 provided on the outer surface, the motor portion 18a is attached to the main body portion 21a while being pressed into the main body portion 21a.

  Further, as shown in FIGS. 2 to 4, the presser fitting 23 is provided with an opening 23 b into which the circuit portion 18 c of the vibration motor 18 is inserted and protrudes upward. Thereby, as shown in FIG. 1, the leaf | plate spring-shaped terminal board 25 is contacting elastically with the circuit part 18c of the vibration motor 18. As shown in FIG. The terminal plate 25 is configured to electrically connect the circuit portion 18 c of the vibration motor 18 and a circuit board (not shown) in the timepiece module 7.

Next, the operation of such a wristwatch will be described.
First, when attaching the vibration motor 18 to the diaphragm 16, the motor portion 18 a of the vibration motor 18 is disposed in the main body portion 21 a of the motor holding portion 21 formed integrally with the diaphragm 16 by insert molding. At this time, the pair of eccentric rotating portions 18b are arranged in a state of protruding outward from both sides of the main body portion 21a.

  In this state, the presser fitting 23 is disposed on the main body portion 21 a of the motor holding portion 21. At this time, the engagement pieces 23a on both sides of the presser fitting 23 are engaged with the respective hook portions 24 provided on the outer surfaces on both sides of the main body portion 21a. Then, the motor portion 18a is pressed into the main body portion 21a by the presser fitting 23. As a result, the vibration motor 18 is attached to the motor holding portion 21.

  When attaching the vibration plate 16 to which the vibration motor 18 is attached to the back cover 6 in this way, first, the vibration plate 16 is disposed in the opening 15 of the back cover 6. In this state, the elastic body 17 is bonded to the inner surface of the back cover 6 and the inner surface of the diaphragm 16 so as to straddle both the outer peripheral edge of the vibration plate 16 and the inner peripheral edge of the opening 15 of the back cover 6. Thereby, the diaphragm 16 and the back cover 6 are elastically connected by the elastic body 17.

  Then, the back cover 6 to which the diaphragm 16 is connected is attached to the lower surface of the case body 2 of the watch case 1. At this time, the timepiece glass 5 is attached to the upper opening of the case body 2 in advance, and the timepiece module 7 is disposed in the case body 2 together with the middle frame 8. When the back cover 6 is attached to the lower surface of the case body 2 in this state, the elastic body 17 is sandwiched between the lower end surface of the middle frame 8, the inner surface of the back cover 6, and the inner surface of the diaphragm 16.

  As a result, the position of the diaphragm 16 is regulated so as not to be pushed into the wristwatch case 1 by the lower end surface of the middle frame 8 even if the diaphragm 16 is pushed into the wristwatch case 1 from below. At this time, the waterproof ring portion 6 a formed integrally with the outer peripheral portion of the elastic body 17 is disposed between the case body 2 and the back cover. Thereby, waterproofing between the case main body 2 and the back cover can be achieved.

Next, the case where the wristwatch is used with the wrist attached will be described.
In this case, the watch band 9 is previously attached to the band attaching portion 2 c of the case body 2, and the watch case 1 is attached to the arm with the watch band 9. At this time, the back cover 6 and the diaphragm 16 are in contact with the arm.

  In this state, when the motor portion 18a of the vibration motor 18 rotates, the pair of eccentric rotation portions 18b rotate eccentrically by the rotation of the motor portion 18a, thereby generating vibration. Then, the motor holding portion 21 vibrates due to the vibration of the vibration motor 18, and the vibration plate 16 vibrates due to the vibration of the motor holding portion 21. At this time, since the diaphragm 16 is elastically connected to the back cover 6 by the elastic body 17, the back cover 6 does not vibrate, and only the diaphragm 16 vibrates.

  As described above, when only the diaphragm 16 vibrates, the mass to vibrate is greatly reduced as compared with the case where the back cover 6 and the wristwatch case 1 are vibrated, so that the amount of energy for driving the vibration motor 18 is reduced. Thus, the vibration amount of the vibration motor 18 is significantly increased. As a result, when the vibration motor 18 vibrates, the vibration plate 16 vibrates strongly together with the motor holding portion 21, and the vibration of the vibration plate 16 is reliably transmitted to the arm.

  Thus, according to this wristwatch, the back cover 6 attached to the back surface of the watch case 1 and provided with the opening 14, and the diaphragm disposed in the opening 15 of the back cover 6 and contacting the arm 16, an elastic body 17 that elastically connects the outer peripheral edge of the diaphragm 16 and the inner peripheral edge of the opening 15 of the back cover 6, and an inner surface of the diaphragm 16 positioned on the inner side of the watch case 1. By virtue of the vibration motor 18 that generates vibration, the vibration of the vibration motor 18 can be efficiently transmitted to the arm with low power consumption.

  That is, in this wristwatch, only the diaphragm 16 can be vibrated by the vibration generated by the vibration motor 18, and the vibration can be reliably transmitted to the arm by the diaphragm 16. For this reason, since it is not necessary to vibrate part or all of the back cover 6 and the wristwatch case 1 with the vibration motor 18, the vibration motor 18 can be vibrated with low power consumption, and vibration of the vibration motor 18 can be efficiently performed. Thus, the vibration motor 18 can be reduced in size.

  Further, in this wristwatch, the elastic body 17 is made of one kind of material selected from elastic materials such as silicone resin, urethane resin, foamed resin, and gel-like low-rebound material, so that Since the vibration plate 16 can be elastically displaced with respect to the back cover 6 in a state where the plate 16 is elastically connected to the back cover 6, only the vibration plate 16 is vibrated reliably and satisfactorily by the vibration motor 18. Can be made.

  In this case, since the elastic body 17 is formed of a silicone resin, a waterproof ring 6 a for waterproofing between the case body 2 and the back cover 6 can be integrally formed on the outer peripheral portion of the elastic body 17. Therefore, the number of parts can be reduced, and the assembling work of the back cover 6 can be simplified, thereby reducing the cost.

  In this wristwatch, the elastic body 17 is continuously formed in a frame shape in a state of straddling the outer peripheral edge of the diaphragm 16 and the inner peripheral edge of the opening 15 of the back cover 6. In addition to elastically connecting the diaphragm 16 to the back cover 6, the gap S between the outer peripheral edge of the diaphragm 16 and the inner peripheral edge of the opening 15 of the back cover 6 can be closed, and the diaphragm Waterproofness between the outer peripheral edge of 16 and the inner peripheral edge of the opening 15 of the back cover 6 can also be secured.

  Further, the elastic body 17 is sandwiched between the lower end surface of the middle frame 8 disposed in the watch case 1 together with the watch module 7, and the inner surface of the back cover 6 and the inner surface of the diaphragm 16. This can also reliably close the gap S between the outer peripheral edge of the diaphragm 16 and the inner peripheral edge of the opening 15 of the back cover 6, and the outer periphery of the diaphragm 16 and the opening 15 of the back cover 6. Waterproofing between the inner periphery and the inner periphery can be achieved reliably and satisfactorily.

  In this case, the lower end portion of the middle frame 8 is disposed across both the outer peripheral edge of the diaphragm 16 and the inner peripheral edge of the opening 15 of the back cover 6, so that the diaphragm 16 is placed in the watch case 1. The function as a position control part which prevents pushing in can be fulfilled. That is, when the diaphragm 16 is pushed into the wristwatch case 1, the outer peripheral edge of the diaphragm 16 comes into contact with the lower end portion of the middle frame 8, so that the diaphragm 16 is pushed into the wristwatch case 1 and the timepiece module 7. Can be prevented from being damaged.

  Further, the diaphragm 16 is formed so that its thickness is the same as or slightly thinner than the thickness of the back cover 6, so that the outer peripheral edge of the diaphragm 16 can be used when the watch case 1 is attached to the arm. It is possible to prevent the cuffs of the clothes from being caught on the clothes, thereby preventing the cuffs of the clothes from fraying or falling apart, so that they can be used with good attachment to the arm.

  Furthermore, each of the diaphragm 16 and the opening 15 of the back cover 6 is formed into a non-circular shape by partly biting into one attachment part 20 of the back cover 6. It is possible to prevent the diaphragm 16 from rotating in the surface direction in the opening 15 of the back cover 6 while being arranged in the opening 15 of the back cover 6. Thereby, it is possible to prevent the vibration motor 18 mounted on the vibration plate 16 from being displaced in the wristwatch case 1 and to reliably restrict the position of the vibration motor 18 to a predetermined position.

  In the first embodiment described above, the diaphragm 16 and the opening 15 of the back cover 6 are formed in a non-circular shape, and the diaphragm 16 does not rotate in the surface direction within the opening 15 of the back cover 6. However, the present invention is not limited to this, and the diaphragm 16 and the opening 15 of the back cover 6 may be formed in an elliptical shape or a polygonal shape such as a quadrangle or a pentagon.

  In addition, the present invention is not limited to this. For example, as in the first modification shown in FIG. 5, if the rotation stopper 27 is provided, the diaphragm 16 and the opening 15 of the back cover 6 may be formed in a circular shape. good. That is, the rotation stopper 27 includes a concave portion 27 a provided on the outer peripheral surface of the diaphragm 16 and a convex portion 27 b provided on the inner peripheral surface of the opening 15, and the convex portion 27 b of the opening 15 is provided. It is only necessary that the diaphragm 16 is configured not to rotate in the surface direction in the opening 15 of the back cover 6 by being engaged with the concave portion 27a of the diaphragm 16.

  In the first embodiment described above, the case where the diaphragm 16 is prevented from being pushed into the wristwatch case 1 by the middle frame 8 disposed in the wristwatch case 1 has been described, but the present invention is not limited thereto. For example, as in the second modification shown in FIG. 6, a position restricting portion 28 that prevents the diaphragm 16 from being pushed into the wristwatch case 1 is provided at the diaphragm 16 and the opening 15 of the back cover 6. There may be.

  That is, the position restricting portion 28 includes a position restricting projection 28 a that protrudes from the upper portion of the inner peripheral surface of the opening 15 of the back cover 6 toward the upper portion of the outer peripheral surface of the diaphragm 16, and the outer peripheral surface of the diaphragm 16. It only has to be configured to have a position restricting recess 28b provided in the upper portion and to be in contact with the position restricting projection 28a of the back cover 6 so as to be able to contact and separate.

  Furthermore, in the above-described first embodiment, the case where the elastic body 17 is disposed between the middle frame 8 of the timepiece module 7 and the back cover 6 and the diaphragm 16 is described. A configuration may be adopted in which a part of 17 is extended between the timepiece module 7 and the diaphragm 16 and the extended part is formed as a buffer part between the timepiece module 7 and the diaphragm 16.

  In the first embodiment described above, the case where the circuit portion 18c of the vibration motor 18 and the circuit board of the timepiece module 7 are electrically connected by the terminal plate 25 is described. You may comprise so that the circuit part 18c of the vibration motor 18 and the circuit board of the timepiece module 7 may be electrically connected by connection members, such as a wiring board.

(Second Embodiment)
Next, a second embodiment in which the present invention is applied to a pointer-type wristwatch will be described with reference to FIG. In addition, the same code | symbol is attached | subjected and demonstrated to the same part as 1st Embodiment shown by FIGS. 1-4.
As shown in FIG. 7, this wristwatch has a configuration that is different from that of the first embodiment in the elastic body 30 that elastically connects the back cover 6 and the diaphragm 16, and the other configuration is substantially the same as that of the first embodiment. It has become. Therefore, the configuration of the first modification shown in FIG. 5 and the configuration of the second modification shown in FIG. 6 are also effective in the second embodiment.

  That is, as shown in FIG. 7, the elastic body 30 is disposed in a gap between the inner periphery of the opening 15 of the back cover 6 and the outer periphery of the diaphragm 16, and in this state, the upper end 30 a is the diaphragm. The lower end 30 b is bent and bonded to the outer surface of the back cover 6. In this case, the elastic body 30 is continuously disposed in the gap between the inner peripheral edge of the opening 15 of the back cover 6 and the outer peripheral edge of the diaphragm 16.

  The elastic body 30 is fixed to the inner surface of the diaphragm 16 in a frame shape with the upper end portion 30 a thereof being continuous along the outer peripheral edge of the diaphragm 16. The elastic body 30 is fixed to the outer surface of the back cover 6 in a frame shape with the lower end portion 30 b thereof being continuous along the inner peripheral edge of the opening 15 of the back cover 6. Thereby, the elastic body 30 is configured to elastically connect the diaphragm 16 to the back cover 6.

  Further, the elastic body 30 is a sheet having elasticity, as in the first embodiment, and is formed of any one of a silicone resin, a urethane resin, a foamed resin, and a gel-like low-resilience material. Preferably it is formed of a silicone resin. Therefore, as shown in FIG. 7, the elastic body 30 is configured such that the diaphragm 16 is elastically displaced with respect to the back cover 6 in a state where the diaphragm 16 is elastically connected to the back cover 6. Has been.

  In this case, a buffer sheet 31 is disposed between the timepiece module 7 and the diaphragm 16 in the wristwatch case 1 as shown in FIG. The buffer sheet 31 is configured to restrict the position of the diaphragm 16 so that the diaphragm 16 is not pushed into the watch case 1 when the diaphragm 16 is pushed into the watch case 1 from below. .

Further, a waterproof ring portion 6 a is provided independently between the lower surface of the watch case 1, that is, between the lower surface of the case body 2 and the inner surface of the back cover 6.

  According to such a wristwatch, as in the first embodiment, only the diaphragm 16 can be vibrated by the vibration generated by the vibration motor 18, and the vibration can be reliably transmitted to the arm. For this reason, since it is not necessary to vibrate part or all of the back cover 6 and the wristwatch case 1 with the vibration motor 18, the vibration motor 18 can be vibrated with low power consumption, and vibration of the vibration motor 18 can be efficiently performed. Thus, the vibration motor 18 can be reduced in size.

  In this case, since the elastic body 30 is continuously arranged in a frame shape in the gap between the outer peripheral edge of the diaphragm 16 and the inner peripheral edge of the opening 15 of the back cover 6, the elastic body 30 causes the diaphragm 16 to be arranged. Can be elastically connected to the back cover 6, and the gap S between the outer peripheral edge of the diaphragm 16 and the inner peripheral edge of the opening 15 of the back cover 6 can be reliably closed. Waterproofness between the outer peripheral edge of 16 and the inner peripheral edge of the opening 15 of the back cover 6 can also be secured.

The diaphragm 16 and the back cover 6 can be reliably and satisfactorily connected by the elastic body 30 because the frame is fixed to the outer surface of the back cover 6 in a continuous state along the inner peripheral edge of the back cover 6. In addition, the diaphragm 16 can be suppressed from being pushed into the wristwatch case 1.

  Further, since the buffer sheet 31 is disposed between the timepiece module 7 and the diaphragm 16 in the watch case 1, when the diaphragm 16 is pushed into the watch case 1 from the lower side thereof. Further, the position of the diaphragm 16 can be regulated by the buffer sheet 31 so that the diaphragm 16 is not pushed into the wristwatch case 1. Further, the buffer sheet 31 can prevent the diaphragm 16 from coming into contact with the lower housing 11 of the timepiece module 7 and vibrating the timepiece module 7 due to the vibration of the diaphragm 16.
