  FIG. 1 is a top view crushing perspective view showing a configuration example of a speaker 100 with an actuator function as a first embodiment to which a vibrating body according to the present invention is applied. FIG. 2 is a cross-sectional view supplementing a configuration example of the front surface, and FIG. 3 is a cross-sectional view taken along arrow Y1-Y1 of FIG.

  An ultra-small speaker 100 with an actuator function shown in FIG. 1 is an application of a vibrating body (actuator with a speaker function) according to the present invention. In addition to the speaker function, an actuator function capable of generating a tactile sensation is provided. have. The speaker 100 can be applied to an information processing device that presents a tactile sensation to an operator when selecting an icon from a display screen for selecting an input item and inputting information, a mobile phone, a mobile terminal device, and the like. It is a thing.

  The speaker 100 has a housing portion 6 that constitutes an example of a member housing portion, and the lid member 1 is engaged with the housing portion 6 after the components are incorporated. The size of the housing part 6 is L = 15 [mm], width W = 5 [mm], and height H = L when the length is L, the width is W, and the height is H. It is about 3 [mm]. The lid member 1 has an opening at a predetermined site. In this example, four openings 1a, 1b, 1c, and 1d are provided so that sound leaks to the outside (see FIG. 2). For the lid member 1, for example, a resin molded product is used.

  A vibration yoke 5 that constitutes the function of the bottomed member is disposed inside the housing portion 6. The yoke 5 has a bottomed cylindrical recess 5 a at the center, and is movably disposed in the housing portion 6.

  The yoke 5 in this example is supported at both ends in the length direction by two conductive leaf springs 101 and 102 inside the housing portion 6. The yoke 5 has a left arm 5b and a right arm 5c (hereinafter simply referred to as arms 5b and 5c together) extending on both sides of a bottomed cylindrical recess 5a. The right arm 5 c is supported by the leaf spring 102 while being supported by the leaf spring 101.

  The leaf springs 101 and 102 constitute an example of a pair of support members, and each is disposed at both ends of the housing portion 6 in the longitudinal direction. The leaf springs 101 and 102 are composed of conductive band members that are curved to have elasticity.

  The leaf springs 101 and 102 have intermediate portions 101c and 102c fixed to the bottom of the housing portion 6 to form a movable fulcrum, and one end portions 101a and 102a extending inside the housing portion 6 to support the yoke 5. At the same time, the other end portions 101b and 102b extend to the outside of the housing portion 6 to form an extraction electrode of the coil 3 to be described later.

  Here, the intermediate portions 101c and 102c may include a midpoint in the length direction of the leaf springs 101 and 102, but may not include them. That is, the end portions 101a and 101b are not limited to the same length.

  Further, the leaf springs 101 and 102 of this example are bent at the end portions 101a ′ and 102a ′ of the end portions 101a and 102a, and are fixed to the bottom portion of the housing portion 6 like the intermediate portions 101c and 102c. (See FIG. 3). By doing in this way, since both ends 101a and 102a inside the housing part 6 are fixed to the bottom part of the housing part 6, the leaf | plate springs 101 and 102 can support the yoke 5 substantially horizontally. At the same time, the yoke 5 can vibrate parallel to the height direction inside the housing portion 6.

  Further, in this example, the leaf spring 101 on the left arm 5 b side is bonded to the yoke 5 via the insulating seal 7. The insulating seal 7 is made of an insulating member such as a PET (Polyethylene terephthalate) film, for example, and is attached so as to cover the upper surface, side surface, and lower surface of the left arm 5b. The leaf spring 101 is electrically insulated from the yoke 5.

  On the other hand, the leaf spring 102 on the right arm 5 c side is directly bonded or welded to the yoke 5. The leaf spring 102 is electrically connected to the yoke 5.

  A magnet 4 (permanent magnet) constituting an example of a magnetic body is fixed to the concave portion 5a of the yoke 5. For the magnet 4, for example, neodymium having a prismatic shape is used. A movable coil 3 (voice coil) is movably disposed around the magnet 4. The coil 3 has a winding shaft portion. The coil 3 is supplied with an audio signal, a vibration generation signal, and the like.

  A vibration plate 2 is attached to one side of the winding shaft portion of the coil 3 described above, and an outer edge portion of the vibration plate 2 is sandwiched between the lid member 1 and the housing portion 6.

  In the cross-sectional view shown in FIG. 2, between the two leaf springs 101 and 102 provided outside the bottom surface of the housing portion 6, for example, two openings 6 a and 6 b are formed on the bottom surface portion of the housing portion 6. Is provided. Mesh seals 8a and 8b are affixed to the outside of the two openings 6a and 6b. The mesh seal 8a is provided so as to cover the opening 6a, and the mesh seal 8b is provided so as to cover the opening 6b. The function of the mesh seals 8a and 8b is to ensure the breathing function inside and outside the housing portion 6.

  The leaf springs 101 and 102 are connected to end portions 3a and 3b which are lead wires of the coil 3, respectively. One end 3 a drawn out from the coil 3 extends along the lower surface of the diaphragm 2 and the inner wall of the housing portion 6 and is connected to the end 101 a of the leaf spring 101. Here, since the left side surface of the yoke 5 on the side where the end portion 3a extends is covered with the insulating seal 7, the end portion 3a and the yoke 5 are not electrically short-circuited.

  The other end 3 b drawn from the coil 3 extends along the lower surface of the diaphragm 2, reaches the upper surface of the yoke 5 at a position where the insulation distance from the coil 3 can be maintained, and is connected to the yoke 5. Here, since the yoke 5 and the leaf spring 102 are electrically connected, the end portion 3b and the leaf spring 102 are electrically connected. Thus, the leaf springs 101 and 102 constitute a spring terminal for the coil, and an audio signal to be supplied to the coil 3, a vibration generation signal, and the like can be input between the terminals of the leaf springs 101 and 102.

  Further, weights 9a and 9b are joined to the lower surfaces of the left and right arms 5b and 5c of the yoke 5, respectively. A weight 9a is joined to the lower surface of the left arm 5b using an adhesive. The weight 9b is also bonded to the lower surface of the right arm 5c using an adhesive. The weights of the weights 9a and 9b are about 0.597 [g], for example. The weights 9a and 9b each have a thickness of about 2 mm, and is approximately equal to the distance from the lower surface of each of the left and right arms 5b and 5c to the bottom surface of the housing portion 6. A very small gap is provided between the lower surfaces of the weights 9 a and 9 b and the bottom surface of the housing portion 6. This is to ensure a stroke (space) between the upper and lower sides of the yoke 5 in the direction of the coil winding shaft portion while securing the weights of the weights 9a and 9b. In this example, weights 9 a and 9 b are connected to the inside of the leaf springs 101 and 102 of the yoke 5.

  The leaf spring 101 on the side of the left arm 5b shown in the Y1-Y1 arrow cross-sectional view of FIG. 2 in FIG. 3 has a middle portion 101c and an end portion 101a ′ embedded in the bottom portion of the housing portion 6. It is fixed to the part 6. In this example, the end 101a 'constitutes a movable fulcrum of the end 101a together with the intermediate 101c. The leaf spring 101 and the housing part 6 have an embedded integral structure.

  The end portion 101 a extending inside the housing portion 6 has a curved shape in an arc shape, and a flat portion 101 e serving as a connecting portion of the yoke 5 is provided at a curved upper portion. The flat surface portion 101 e is substantially parallel to the bottom surface of the housing portion 6. Also, bent portions 101d are provided at both ends of the flat portion 101e for increasing the vertical elastic force and vibration width of the end portion 101a. Here, the vertical direction is the height direction of the housing portion 6.

  On the other hand, the end portion 101b extending to the outside of the housing portion 6 has a curved end surface 101b 'so that the curved outer surface is in contact with the external electrode. The end portion 101 b has an elastic force by extending obliquely with respect to the bottom surface of the housing portion 6, and the outermost end portion 101 b ′ constitutes a suitable contact portion for the external electrode.

In this manner, the leaf spring 101 has the functions of the support member and the extraction electrode. Further, the leaf spring 102 on the right arm 5c side is configured in the same manner, and has the functions of a support member and an extraction electrode.
Further, in this example, the end portion 3 a of the coil 3 connected to the leaf spring 101 is sandwiched between the flat portion 101 e and the insulating seal 7 and connected to the leaf spring 101. In this way, the end portion 3 a of the coil 3 is more firmly connected between the leaf spring 101 and the yoke 5.

  FIG. 4 is an exploded perspective view showing an assembly example of the speaker 100 with an actuator function. According to the speaker 100 with an actuator function shown in FIG. 4, first, the housing part 6 is prepared. In this example, the openings 6a and 6b are provided at the bottom, and the housing 6 having the housing reinforcing portions 6e and 6f for controlling the shaking that also serves to attach the leaf springs 101 and 102 is obtained. A predetermined mold is prepared, and an ABS resin or the like is injected into the mold to form a resin molded product. A PC resin may be used instead of the ABS resin.

  At this time, the leaf springs 101 and 102 may be attached to the case reinforcing portions 6e and 6f inside the housing portion 6 by a press-fitting method. Alternatively, the leaf springs 101 and 102 may be incorporated into the mold and simultaneously with the housing portion 6. It is good also as insert molding.

  As the leaf springs 101 and 102, conductive band members curved to have elasticity are used. As the leaf springs 101 and 102, for example, a phosphor bronze plate having a thickness of about 0.5 mm is subjected to sheet metal pressing. The plate springs 101 and 102 are plated. For example, Ni plating of about 2 to 3 μm, Ni-pd plating of about 1 to 3 μm, and Cu plating of about 0.03 μm are applied to the members constituting the leaf springs 101 and 102. Thereby, the housing part 6 as a container which can accommodate vibration components and the like is obtained.

  Next, the magnet 4 and the weights 9a and 9b are attached to the yoke 5. A yoke 5 having a bottomed cylindrical recess 5a at the center and arms 5b and 5c on the left and right is used. The yoke 5 has a length of L ′, a width of W ′, and a height of H ′ of L ′ = 10 [mm], a width W ′ = 3 [mm], The height H ′ is about 1.5 [mm]. In this example, a stainless steel plate (SUS301) having a thickness of about 0.3 mm is subjected to sheet metal press working to form a bottomed cylindrical concave portion 5a at the center and a yoke 5 having arms 5b and 5c on the left and right.

  Here, the insulating seal 7 is stuck or adhered to the left arm 5b. For the insulating seal 7, for example, a PET (Polyethylene terephthalate) film (seal) having a thickness of about 25 μm and having adhesiveness on one surface is used. Here, the insulating seal 7 is stuck so as to cover the upper surface, side surface, and lower surface of the left arm 5b.

  The magnet 4 is joined to the bottom surface of the bottomed cylindrical recess 5 a of the yoke 5. For example, it joins using a urethane type adhesive. The magnet 4 is a magnetic member having a prismatic shape such as neodymium.

  A weight 9a is joined to the lower surface of the left arm 5b using an adhesive. The weight 9b is also bonded to the lower surface of the right arm 5c using an adhesive. The weights of the weights 9a and 9b are about 0.597 [g], for example. Use urethane-based adhesive. Thereby, a vibration component that can be accommodated in the housing portion 6 is obtained.

  Next, the diaphragm 2 and the coil 3 are joined to form a voice coil component. For the diaphragm 2, a film member having a size approximately the same as that of the lid member 1 and a thickness of about 25 μm is used. PEN or PET is used for the film member, and the diaphragm 2 is processed into a cone shape. For the coil 3, a copper wire of about 0.05 mm is used. The coil 3 is formed to have a hollow shape in which a copper wire is wound into a prismatic shape a predetermined number of times.

  When the diaphragm 2 and the coil 3 are prepared, one side of the prismatic coil 3 is joined to the center of the back surface of the diaphragm 2. At this time, the diaphragm 2 and the coil 3 are joined using a urethane-based adhesive. Thereby, a voice coil component that can be attached to the upper portion of the housing portion 6 is obtained.

  When the above-described vibration parts and voice coil parts are prepared, these are housed in, for example, the housing portion 6 with the leaf springs 101 and 102, and the speaker 100 with the actuator function is assembled.

  In this example, when housed, the end portion 3 a of the coil 3 is soldered to the end portion 101 a of the leaf spring 101 inside the housing portion 6. The end 3a is preferably connected to the upper surface of the flat portion 101e of the leaf spring 101, but may be bonded to another portion of the leaf spring 101 in consideration of assembly efficiency.

  Alternatively, a conductive thin film electrically connected to the intermediate portion 101c of the leaf spring 101 may be formed on the inner wall of the housing portion 6 by printing or the like, and the end portion 3a may be soldered to the thin film. .

  Similarly, the lead wire 3 b of the coil 3 is soldered and connected to the upper surface of the right arm 5 c of the yoke 5 inside the housing portion 6.

  Thereafter, the yoke 5 is mounted on the housing portion 6. At this time, the lower surfaces of the left and right arms 5b and 5c of the yoke 5 are bonded to the upper surfaces of the flat portions 101e and 102e of the leaf springs 101 and 102, respectively. A leaf spring 101 may be bonded to the left arm 5b to which the insulating seal 7 is attached with an insulating adhesive, an adhesive member, or the like. In addition, the leaf spring 102 may be bonded (welded) to the right arm 5c by a conductive adhesive, an adhesive member, or soldering.

  Thereafter, the diaphragm 2 to which the coil 3 is joined is fitted from above the housing portion 6. At this time, the coil 3 is assembled so that the winding shaft portion of the coil 3 covers the magnet 4. Thereafter, the lid member 1 and the housing part 6 are aligned, and the outer edge part is joined using an adhesive or the like so that the outer edge part of the diaphragm 2 is sandwiched between the lid member 1 and the housing part 6. Thereby, the speaker 100 with an actuator function in which the yoke 5 is movable inside the housing portion 6 as shown in FIG. 1 is completed.

  Thus, according to the speaker 100 with an actuator function as the first embodiment of the present invention, the pair of leaf springs 101 and 102 fixed to the bottom portion of the housing portion 6 with the intermediate portion as a movable fulcrum is provided. One end of the leaf springs 101 and 102 extends into the housing portion 6 to support the yoke 5, and the other end extends to the outside of the housing portion 6 to form a signal input lead electrode. It is.

  With this configuration, the movable fulcrum, the support member, and the extraction electrode can be configured as a single member, so that the number of components applied to the speaker 100 can be reduced. As a result, the speaker 100 can be reduced in size, weight, and cost.

  In addition, for example, the support member and the extraction electrode can be configured with parts having a simple structure obtained by sheet metal pressing a plated phosphor bronze plate. Furthermore, since the leaf springs 101 and 102 can be fixed to the housing portion 6 by insert molding of the leaf springs 101 and 102 at the time of injection molding of the housing portion 6, the manufacturing process can be reduced.

  FIGS. 5A and 5B are perspective views showing a configuration example of weights 9 ′ and 9 ″ as other embodiments applicable to the speaker 100. A weight 9 ′ shown in FIG. 5A is bonded to the lower surface of the yoke 5 ′, thereby combining the functions of the weights 9 a and 9 b of the first embodiment.

  A yoke 5 ′ shown in FIG. 5A constitutes an example of a bottomed member, and has a bottomed recess 5 a ′ at the center. The yoke 5 ′ is provided with arm portions 5 b ′ and 5 c ′ at both ends in the longitudinal direction of the recess 5 a ′, and flange portions 5 d ′ and 5 e ′ at both ends in the short direction.

  The weight 9 'has an outer shape substantially the same as the outer shape of the yoke 5', and a hole 9a 'is opened at the center. The hole 9a 'is sized to fit the recess 5a'. Arms 9b 'and 9c' are extended at both ends in the longitudinal direction of the hole 9a ', and flanges 9d' and 9e 'are extended at both ends in the short direction.

  With the recess 5a ′ fitted in the hole 9a ′, the arm portions 9b ′ and 9c ′ and the flange portions 9d ′ and 9e ′ are formed on the lower surfaces of the arm portions 5b ′ and 5c ′ and the flange portions 5d ′ and 5e ′. The weight 9 'and the yoke 5' are connected to each other by adhering the upper surface.

  On the other hand, the weight 9 '' shown in FIG. 5B also has the functions of the weights 9a and 9b of the first embodiment. The weight 9 '' has a hole 9a '', arms 9b '' and 9c '', and flanges 9d '' and 9e ''. A yoke 5 '' is connected to the weight 9 ''.

  A yoke 5 ″ shown in FIG. 5B constitutes an example of a bottomed member, and has a bottomed concave portion 5a ″ in which the magnet 4 and the coil 3 can be accommodated. The yoke 5 ″ does not have portions corresponding to the arm portion and the flange portion. By fitting and adhering the yoke 5 ″ to the hole 9a ″ of the weight 9 ″, the weight 9 ″ and the yoke 5 ″ are connected.

  In order to support the weights 9 ′ and 9 ″ with the leaf springs 101 and 102, the upper surfaces of the end portions 101a and 102a of the leaf springs 101 and 102 are bonded to the lower surfaces of the weights 9 ′ and 9 ″. It is good to. In that case, for example, the insulating seal 7 is stuck so as to cover the upper surface, the side surface, and the lower surface of the arm portions 5b 'and 9b', 9b ''.

  As described above, according to the weights 9 ′ and 9 ″ according to the other embodiments, the leaf springs 101 and 102 can be bonded to the lower surfaces of the arm portions of the weights 9 ′ and 9 ″. Unlike the yoke 5, it is not necessary to bond the weights 9 a and 9 b inside the leaf springs 101 and 102. Accordingly, the length of the speaker 100 in the longitudinal direction can be reduced.

  In addition, since one member such as the weights 9 'and 9' 'can be used as the left and right weights 9a and 9b, the number of members can be reduced and the manufacturing process can be simplified.

  Thus, the speaker 100 with an actuator function can be reduced in size. This makes it possible to provide a very small receiver (receiver) with an actuator function, and in particular, the receiver can be sufficiently applied to an input device with a tactile function on the display unit side of a mobile phone (terminal device). .

  FIG. 6 is an exploded perspective view showing a configuration example of a speaker 200 with an actuator function as the second embodiment.

  The speaker 200 of this example includes a yoke 205 having a configuration different from that of the first embodiment, a housing portion 206, and leaf springs 201 and 202. In the speaker 200, the yoke 205 is movably supported at the center portion in the longitudinal direction of the housing portion 206. In this example, the same reference numerals and the same names as those in the first embodiment have the same function and the same structure, and thus the description thereof is omitted.

  The yoke 205 shown in FIG. 6 constitutes an example of a bottomed member, and has a bottomed recess 205a at the center. Arms 205b and 205c extend at both ends in the longitudinal direction of the recess 205a, and flanges 205d and 205e extend at both ends in the short direction. In this example, the arm portions 205b and 205c and the flange portions 205d and 205e are formed from one continuous surface.

  The yoke 205 is supported from the lower surface by leaf springs 201 and 202 curved in a substantially C shape. The leaf springs 201 and 202 constitute an example of a pair of support members, and are composed of a phosphor bronze plate having a thickness of about 0.5 mm, as with the leaf springs 101 and 102 of the first embodiment.

The yoke 5 is supported in the state. Therefore, the arms 5b and 5c of the yoke 5 can vibrate efficiently with a large vibration width.

  Further, since the intermediate portions 301c and 302c serving as the movable fulcrums of the leaf springs 301 and 302 are greatly inclined as compared with the first and second embodiments, the intermediate portions 301c and 302c are embedded in the housing portion 6. The length can be increased. Accordingly, the leaf springs 301 and 302 are stably fixed to the housing portion 6.

  As a result, the leaf springs 301 and 302 can be miniaturized, and an ultra-small receiver (receiver) with an actuator function can be provided. Accordingly, similarly to the first embodiment, the receiver can be sufficiently applied to an input device with a tactile function on the display unit side of the mobile phone (terminal device).

At the same time, the lower terminals 401b and 402b are extended to the outside of the housing portion 6 to form an extraction electrode of the coil 3.

  In the yoke 5 of the speaker 400 shown in FIG. 9, a nut fitting portion 5b 'is opened in the left arm 5b, and a screw hole portion 5c' is opened in the right arm 5c. In this example, an insulating nut 7a is fitted into the nut fitting portion 5b '.

  The insulating nut 7a is a nut of a predetermined size made of an insulating member, and the outer shape is set to be substantially the same shape and size as the inner shape of the nut fitting portion 5b '. The insulating nut 7a is fixed to the left arm 5b by, for example, integral molding with the yoke 5 or an adhesive. A screw hole portion 7b having substantially the same shape as the screw hole portion 5c 'is opened at the center of the insulating nut 7a. The upper terminal 401a of the spring terminal 401 is connected to the screw hole 7b.

  The upper terminal 401 a of the spring terminal 401 includes a screw part 411 and a nut pipe part 421. The screw portion 411 is a screw made of a metal member having conductivity, and has a head portion and a shaft portion. A screw groove is cut in the outer peripheral surface of the shaft portion.

  The nut pipe portion 421 has a cylindrical shape with a screw hole formed in the upper surface and a lower surface opened. On the inner peripheral surface of the screw hole of the nut pipe portion 421, a screw groove that can be screwed with the screw portion 411 is cut.

  The upper terminal 401a is screwed into the screw hole on the upper surface of the nut pipe portion 421 disposed on the lower side of the arm 5b after the screw portion 411 passes the shaft portion from the upper side of the yoke 5 to the screw hole portion 7b. Thus, it is fixed to the left arm 5b. Here, the spring terminal 401 is electrically insulated from the yoke 5 by the insulating nut 7a.

  On the other hand, the upper terminal 402a of the spring terminal 402 is connected to the screw hole 5c 'of the right arm 5c. The upper terminal 402a includes a screw portion 412 having a head portion and a shaft portion made of a metal member having conductivity, and a cylindrical nut tube having a screw hole formed in the upper surface and a lower surface opened.

Is fixed to the right arm 5c. Here, the spring terminal 402 and the yoke 5 are electrically connected.

  Further, tube portions 401c and 402c which are intermediate portions of the spring terminals 401 and 402 and function as support portions are embedded in the bottom portion of the housing portion 6. The tube portions 401c and 402c hold the positions of the upper terminals 401a and 402a and the lower terminals 401b and 402b movably with respect to the housing portion 6.

  The pipe parts 401c and 402c have a shape in which both pipe end parts are inclined inward and the opening part is narrowed. The tube portions 401 c and 402 c are fixed, for example, by integral molding in the vicinity of both ends in the longitudinal direction of the housing portion 6 so that the respective tube end portions open to the inside and the outside of the housing portion 6.

  The lower terminal side of the upper terminal 401a is engaged with the upper opening part of the tube part 401c fixed to the left side of the housing part 6 so as not to come off. The upper terminal 401a has a shape in which the lower side of the nut pipe part 421 is inserted into the pipe of the pipe part 401c, and the opening on the lower side of the inserted nut pipe part 421 greatly expands outside in the pipe of the pipe part 401c. By doing so, it is prevented from coming out of the opening of the tube portion 401c.

  Similarly, the upper terminal 402a of the spring terminal 402 is engaged with the opening on the upper side of the tube part 402c fixed to the right side of the housing part 6 so that the upper terminal 402a can be expanded and contracted.

  Further, the lower terminal 401 b of the spring terminal 401 includes a screw part 431 and a nut pipe part 441, and the lower terminal 402 b of the spring terminal 402 includes a screw part 432 and a nut pipe part 442. The lower terminals 401b and 402b are configured in substantially the same manner as the upper terminals 401a and 402a, and are engaged with the lower openings of the tube portions 401c and 402c so as to be extendable and not pulled out.

  That is, the lower terminals 401b and 402b also have a shape in which the portions inserted into the tube portions 401c and 402c of the opening portions of the nut tube portions 441 and 442 are widened inside the tube portions 401c and 402c. 402c cannot be removed.

  Further, the screw portion 411 of the upper terminal 401a of the spring terminal 401 and the screw portion 431 of the lower terminal 401b are connected to each other so as to be extendable and conductive by a spring 401d. The spring 401d is a spring spring that connects the upper terminal 401a and the lower terminal 401b so as to be extendable and contractable with respect to the tube portion 401c.

  The spring 401d is inserted or inserted into the pipes of the pipe part 401c and the nut pipe parts 421 and 441 communicating with each other, and the shaft parts of the screw parts 411 and 431 are connected or contacted to both ends. Thus, the screw portions 411 and 431 are also electrically connected.

  Similarly, the screw portion 412 of the upper terminal 402a of the spring terminal 402 and the screw portion 432 of the lower terminal 402b are connected to each other so as to be extendable and conductive by a spring 402d.

  The end 3 a of the coil 3 is connected to the head of the screw portion 411 so as not to touch the yoke 5. Here, the spring terminal 401 to which the end 3a is connected is electrically insulated from the yoke 5 by the insulating nut 7a. The outer shape of the insulating nut 7 a is set to a predetermined size such that the end 3 a connected to the screw portion 411 does not contact the yoke 5.

  Further, instead of the insulating nut 7a, a predetermined portion of the left arm 5b of the yoke 5 may be formed of an insulating member. Alternatively, the left arm 5b in which the screw hole 7b is opened may be coated with an insulating member. In this way, the spring terminal 401 has the function of the support member of the yoke 5 and the spring terminal for the extraction electrode of the end 3a.

  On the other hand, the end 3 b of the coil 3 is connected to the head of the screw portion 412. Alternatively, it is connected to the upper surface of the yoke 5 as in the first embodiment. The spring terminal 402 functions as a support member for the yoke 5 and a spring terminal for the extraction electrode at the end 3b.

  When assembling the speaker 400 of this example, the spring terminals 401 and 402 with the screw portions 411 and 412 on the upper terminal side removed are insert-molded at the time of injection molding of the housing portion 6, and the screw portions 411 and 412 are screwed. By combining, the yoke 5 may be coupled to the member on the housing portion 6 side.

  At that time, the spring 401d and the screw portion 411 can be electrically contacted with each other by being pressed against each other. Alternatively, since the screw part 411 and the nut pipe part 421 are connected to each other by being screwed together, the upper end part of the spring 401d may be connected to the upper side of the nut pipe part 421. .

  Alternatively, the terminal of the spring 401d may be pulled out from the screw hole portion of the nut tube portion 421 and connected to the screw portion 411 by soldering or the like, and then the screw portion 411 may be screwed into the nut tube portion 421.

  As described above, according to the speaker 400 with the actuator function as the fourth embodiment, the spring terminals 401 and 402 that can be expanded and contracted in the height direction of the housing portion 6 and that can freely vibrate are arranged in the longitudinal direction of the yoke 5. While supporting both ends movably, the extraction electrode of the coil 3 is comprised.

  Accordingly, the left and right arms 5b and 5c of the yoke 5 vibrate with a predetermined swing width according to the elastic force of the springs 401d and 402d. Therefore, the swing width can be easily adjusted by appropriately changing the spring spring used. it can. Thereby, it is easy to control the magnitude of the swing width of the yoke 5. Further, since the spring terminals 401 and 402 expand and contract in parallel with the height direction of the housing portion 6, the vibration direction of the yoke 5 is stabilized.

  Further, the support member for the yoke and the extraction electrode for the coil can be constituted by a single member engaged in a bar shape. This makes it possible to provide an ultra-small receiver (receiver) with an actuator function, and input the receiver with a tactile function on the display unit side of the mobile phone (terminal device) in the same manner as in the first embodiment. It will be fully applicable to equipment.

The mounting structure is supported by 64b and the straight rib 64c on the left side and is movable in the right direction. In this example, the input unit 24 and the display unit 29 are mounted so that the right surface side thereof abuts against (presses against) the side surface of the speaker 36b.

  In the panel side case 20b, the speaker 36b is supported by upper and lower L-shaped ribs 62a and 62b and a claw-like engagement member 63 on the right side in a state where the extraction electrodes 107a and 107b face upward. The mounting structure is movable in the left direction. Here, the extraction electrodes 107a and 107b correspond to the spring terminals 101 and 102 of the first embodiment, and have both a support member for the yoke of the speaker 36b and an extraction electrode for the coil. In this example, the speaker 36b is mounted such that the left side thereof comes into contact with (presses against) the side surfaces (the end surfaces) of the input unit 24 and the display unit 29.

  Thereafter, as shown in FIG. 13, the substrate side case 20a and the panel side case 20b are aligned and engaged. At this time, the flat plate electrode 66a and the extraction electrode 107a are brought into contact with and brought into contact with each other, and are electrically connected. Similarly, the plate electrode 66b and the extraction electrode 107b are brought into contact with each other and brought into contact with each other to be electrically connected. As a result, when the input detection means 45 detects the contact position of the operator who performs the input operation on the display screen, the yoke 5 vibrates in the housing portion 6 based on the vibration generation signal, thereby the input means 24 and the display means 29. Vibration can be transmitted to At this time, the speaker 36b with an actuator function vibrates the display screen from the side surface direction based on the position information obtained from the input detection means 45.

  Next, a mobile phone 500 with a tactile input function will be described. FIG. 14 is a block diagram illustrating a configuration example of the control system of the mobile phone 500 and an example of a feedback feedback function thereof.

  A cellular phone 500 shown in FIG. 14 is configured by mounting blocks of various functions on the circuit board 17 of the lower housing 10. In addition, the part corresponding to each part and means shown in FIGS. 10-13 is shown with the same code | symbol. The mobile phone 500 includes a control unit 15, an operation panel 18, a reception unit 21, a transmission unit 22, an antenna duplexer 23, an input detection unit 45, a display unit 29, a power supply unit 33, a camera 34, a microphone 13, a storage unit 35, an incoming call. It has a melody speaker 36a and a speaker 36b with an actuator function.

  The input detection means 45 shown in FIG. 14 has been described with reference to the capacitance type input device in FIG. 13, but any device can be used as long as it can distinguish between the function of curling and the selection. (SAW), an optical method, a multi-stage tact switch, or the like may be used. Preferably, any input device having a configuration in which position detection information and force detection information are provided to the control unit 15 may be used. The input detection means 45 described above receives at least the position detection signal S1 and the input detection signal S2 that is the input amount (pressing force; pressing force F) via the finger 30a of the operator 30.

  The control unit 15 constitutes a control system, and includes an image processing unit 26, an A / D driver 31, a video & audio processing unit 44, a CPU 32, and a memory unit 37. The A / D driver 31 is supplied with the position detection signal S1 and the input detection signal S2 from the input detection means 45. The A / D driver 31 converts an analog signal composed of the position detection signal S1 and the input detection signal S2 into digital data in order to distinguish the functions of cursoring and icon selection. In addition to this, the A / D driver 31 performs arithmetic processing on this digital data to detect whether it is a cursoring input or icon selection information, and flag data D3 or position detection information D1 or input detection for distinguishing between the cursoring input and the icon selection The information D2 is supplied to the CPU 32. These calculations may be executed in the CPU 32.

  A CPU 32 is connected to the A / D driver 31. The CPU 32 controls the entire telephone set based on the system program. The storage means 35 stores system program data for controlling the entire telephone. A RAM (not shown) is used as a work memory. When the power is turned on, the CPU 32 reads out system program data from the storage means 35 and develops it in the RAM, starts up the system and controls the entire mobile phone. For example, the CPU 32 receives position detection information D1, input detection information D2, and flag data D3 (hereinafter also simply referred to as input data) from the A / D driver 31, and sends predetermined command data D to the power supply unit 33, the camera 34, Control is performed such that the data is supplied to devices such as the storage unit 35, the memory unit 37, and the video & audio processing unit 44, the reception data from the reception unit 21 is taken in, and the transmission data is transferred to the transmission unit 22.

  In this example, the CPU 32 compares the input detection information D2 obtained from the input detection means 45 with a preset pressing determination threshold value Fth, and controls the vibration of the speaker 36b with an actuator function based on the comparison result. The memory unit 37 is read and controlled. For example, if the tactile sensations propagated from the input detection surface at the pressed position of the input detection unit 45 are A and B, the tactile sensation A lowers the input detection surface corresponding to the pressure F of the operator's finger 30a at the pressed position. It is obtained by changing from a vibration pattern having a frequency and a small amplitude to a vibration pattern having a high frequency and a large amplitude. The tactile sensation B is obtained by changing the input detection surface corresponding to the pressure F of the operator's finger 30a at the pressed position from a high frequency and large amplitude vibration pattern to a low frequency and small amplitude vibration pattern. It is done.

  Storage means 35 is connected to the CPU 32 described above, for example, display information D4 for displaying the input item selection display screen three-dimensionally, and the icon selection position and vibration mode corresponding to the display information D4. Control information Dc and the like are stored for each display screen. The control information Dc can generate a plurality of different tactile sensations synchronized with an application (three-dimensional display or various display contents) on the display means 29, and a plurality of specific vibration waveforms that generate the tactile sensations, and An algorithm for setting a specific haptic generation mode for each application is included. For the storage means 35, an EEPROM, a ROM, a RAM, or the like is used.

  In this example, the CPU 32 performs display control of the display means 29 and output control of the speaker 36b with an actuator function based on the position detection information D1, output detection information D2, and flag data D3 output from the A / D driver 31. . For example, the control unit 15 reads the control information Dc from the storage unit 35 based on the position detection signal S1 obtained from the input unit 24 and the input detection signal S2 obtained from the force detection units 55a to 55d, and accesses the memory unit 37. Then, control is performed so as to supply the vibration generation signal Sout2 to the speaker 36b with an actuator function.

  For example, the CPU 32 activates the tactile sense A when the input detection means 45 detects the input detection information D2 exceeding the press determination threshold Fth, and then detects the input detection information D2 below the press determination threshold Fth. The memory unit 37 is read and controlled so as to start up. In this way, it is possible to generate different vibration patterns in accordance with the “pressing force” of the operator's finger 30a and the like.

  A memory unit 37 is connected to the CPU 32, and vibration generation data Da is read based on the control information Dc from the CPU 32. The vibration generation data Da has an output waveform composed of a sine waveform. A video & audio processing unit 44 is connected to the memory unit 37, and each vibration generation data Da is supplied to the video & audio processing unit 44, and the vibration generation data Da is subjected to audio processing (digital / analog conversion / amplification etc.). The vibration generation signal Sout2 is supplied to the speaker 36b with an actuator function. The speaker 36b vibrates based on the vibration generation signal Sout2.

  In this example, the memory unit 37 stores a pressing determination threshold value Fth corresponding to each application. For example, the pressing determination threshold value Fth is stored in advance in a ROM or the like provided in the storage unit 35 as a trigger parameter. Under the control of the CPU 32, the storage means 35 inputs the input detection information D2, compares the preset pressing determination threshold Fth with the pressure F obtained from the input detection information D2, and determines that Fth> F. Processing or determination processing such as Fth ≦ F is executed.

  For example, when the pressing determination threshold Fth = 100 [gf] is set in the memory unit 37, the input detection surface is vibrated based on the vibration pattern for obtaining the tactile sensation of the classic switch. When the pressing determination threshold Fth = 20 [gf] is set, the input detection surface is vibrated based on a vibration pattern for obtaining a tactile sense of the cyber switch.

  In addition to the memory unit 37, the image processing unit 26 is connected to the CPU 32, and the display information D4 for three-dimensionally displaying button icons and the like is subjected to image processing. Display information D4 after image processing is supplied to the display means 29. In this example, the CPU 32 controls display of the display means 29 so that the button icons in the display screen are displayed in a three-dimensional manner with a perspective in the depth direction.

  The input device 90 configured in this way, for example, presses (contacts) one of a plurality of button icons displayed on the input item selection display screen to move the input unit 24 in the Z direction on the display screen. When pressed, a screen input operation is performed with a sense of touch. The operator 30 receives the vibration of the finger 30a and feels the vibration of each button icon as a tactile sensation.

  The display contents of the display means 29 are determined by the eyes of the operator's eyes 30b, and the sound emission from the speakers 36a, 36b and the like is determined by the sounds of the operator's ears 30c. The operation panel 18 is connected to the CPU 32 described above, and is used, for example, when manually inputting the telephone number of the other party. In addition to the icon selection screen described above, the display unit 29 may display an incoming video based on the video signal Sv.

  Further, the antenna 16 shown in FIG. 14 is connected to the antenna duplexer 23, and receives a radio wave from the other party from a base station or the like when an incoming call is received. A receiver 21 is connected to the antenna duplexer 23, receives reception data guided from the antenna 16, demodulates video and audio, and outputs the demodulated video and audio data Din to the CPU 32 and the like. The A video & audio processing unit 44 is connected to the receiving unit 21 through the CPU 32, and digital audio data is converted from digital to analog to output an audio signal Sout1, or digital video data is converted from digital to analog and converted into a video signal. Sv is output.

  Connected to the video & audio processing unit 44 are a speaker 36a for large sound and a speaker 36b with an actuator function for constituting a receiver. The speaker 36a is configured to ring a ringtone, a ringtone or the like based on the acoustic signal Sout1 when an incoming call is received. The speaker 36b receives the audio signal Sout2 and expands the other party's speech 30d. The speaker 36b vibrates based on the vibration generation signal Sout2 when presenting a tactile sensation.

  In addition to the speakers 36a and 36b, the video & audio processing unit 44 is connected to the microphone 13 constituting the transmitter, and collects the voice of the operator and outputs the audio signal Sin. The video & audio processing unit 44 performs analog / digital conversion on the analog audio signal Sin to be sent to the other party at the time of calling and outputs digital audio data, or analog / digital conversion of the analog video signal Sv. Digital video data is output.

  In addition to the receiving unit 21, the transmitting unit 22 is connected to the CPU 32 to modulate the video and audio data Dout and the like to be sent to the other party, and supply the modulated transmission data to the antenna 16 through the antenna duplexer 23. To be made. The antenna 16 radiates a radio wave supplied from the antenna duplexer 23 toward a base station or the like.

  In addition to the transmission unit 22, a camera 34 is connected to the CPU 32 described above, and a subject is photographed. For example, still image information and operation information are transmitted to the other party through the transmission unit 22. The camera 34 may be provided on the back side of the upper housing 20. The power supply unit 33 includes a battery 14, a CPU 32, an operation panel 18, a receiving unit 21, a transmitting unit 22, a display unit 29, a camera 34, a storage unit 35, a memory unit 37, a video & audio processing unit 44, and an input. DC power is supplied to the detecting means 45. In this example, the case where the memory unit 37 is provided separately from the video & audio processing unit 44 has been described, but a storage device provided in the video & audio processing unit 44 may also be used. The number of parts can be reduced.
