Description

Holder for attachment of vibration generating device {FIXING HOLDER OF VIBRATION GENERATING DEVICE}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates mainly to a vibration generating device operating with a silent alarm function mounted on a portable communication device (including electronic devices such as mobile phones, PHSs, small wireless communication devices, and other portable information communication terminals). Specifically, the present invention relates to a holder for attachment for determining a holding structure and a fixed position between a circuit board in a portable communication device case and the vibration generating device mounted on the circuit board.

For example, in a quiet public place where people such as art galleries, concert halls, etc. gather, consultation or important meetings, sudden ringing of a mobile communication device may be a big problem for the people around. Therefore, a silent alarm function (generally referred to as silent mode) using a vibration generating device that notifies the incoming call notification by bodily vibration by vibrating is mounted in various portable communication devices.

There are two kinds of vibration generating devices, which are largely divided in structure. One of them is a vibration generating motor using a so-called cylindrical or flat motor (hereinafter, simply referred to as a vibration motor if necessary). The other is also called a multi-function device having a so-called sound and buzzer function or a vibration linear device specialized only for the vibration function, which is a speaker drive type that reciprocates a magnetic circuit part with a low frequency signal. Simply referred to as a vibration actuator).

In the case of the vibrating motor, a weight or an eccentric part of the eccentric center is provided on the rotating shaft to be driven, and a mobile phone or the like is made by using an uneven centrifugal force in which the eccentric center positions of the weight and the like rotate during rotation of the rotor part. By vibrating the portable communication devices, the spread rate and the frequency of their use are also increasing day by day as the various types of portable communication devices are spread.

Similarly, in the vibration actuator, in addition to the vibration generating function of the magnetic circuit part due to the low frequency signal, it also has a sounding function of the sound region at the same time, thereby improving the efficiency of the installation space in the flat multifunctional integrated parts instead of the existing speaker. Can be realized, and its use is spreading according to the use. In particular, in recent years such as cellular phones and PHSs, which are widely spread and miniaturized, these two types of vibration generating devices are efficiently arranged and mounted in a limited mounting space in the case.

In these portable communication device cases, the power feeding method and the attachment structure from the power supply side (mainly circuit board) to the main body of the device for generating vibration are improved day by day, and one of them changes from the conventional lead wire soldering or connector connecting method, and is elastically pressed. The structure which combined the sieve and the feed terminal on a leaf spring, and the direct attachment structure by the solder reflow to a circuit board are newly examined.

For example, the vibration motor can be inserted into a case of a portable communication device (hereinafter, simply referred to as the device main body as needed) in a relatively small number of steps in the assembling operation, and directly into the motor main body from the circuit board side. As a method of enabling a power supply, there is conventionally a power supply terminal structure as shown in FIGS. 7 and 8.

The power supply terminal 104 shown in FIG. 7 is arranged in the terminal block 110 which becomes an attachment part of the housing case 103 end of the vibration motor 102 which has the weight 106, and one side is connected with the terminal by the connection part 104e. A part of the strip | belt shape which is soldered and runs from the said terminal block 110 to the contact part 104d is comprised by the leaf spring of the shape bent at the bending part 104f.

Due to the spring elasticity in the vicinity of the bent portion 104f, as illustrated in FIG. 8, the circuit board 50 provided with the contact portion 104d on the front end side of the movable portion 104 of the power supply terminal 104 in the device case 200. Pressing on the feed land (55). And as shown to FIG. 8 (b), 130g of elastic pressing bodies as a part of the holder 130 which covers the outer periphery of the said housing case 103 between the power supply terminal 104 and the housing case 103. As shown to FIG. And the casing 200 on the device side, the force of the interaction between the rubber elastic stress of the convex portion of the elastic pressing body 130g and the leaf spring elastic stress of the feed terminal 104, There is a method of pressing the contact portion 104d of the power supply terminal 104 with the power supply land 55 (for example, see Patent Documents 1 to 3).

(Problem that invention tries to solve)

However, in the case of the above patent document, for example, the vibration motor (102 in FIG. 7) is placed on the plate surface of the circuit board 50 and further supports the vibration motor 102 as shown in FIG. 8. Since the feed terminal 104 is sandwiched between the pressing portion 130g of the elastic holder 130 and the circuit board 50, the space in the height direction in the device case 200 is increased and thinning is desired. There was a problem that did not meet the development standards of the mobile communication device.

As a practical matter, for the outer diameter close to φ4 mm, which is the minimum diameter of the current cylindrical vibration motor, the height dimension through the elastic holder 130 is about 5 mm in total thickness, which is much larger among electronic components mounted on other circuit boards. , High dimension. In particular, in a portable communication device typified by a mobile phone, miniaturization is strongly desired, and the arrangement position of vibration generating devices such as the vibration motor and the like has always been a problem. Furthermore, as the vibrating motor 102 is reduced in size, the diameter of the eccentric weight 106 is also reduced, and thus, the vibration motor 102 cannot be obtained with a sufficient level of vibration force. There was a problem.

In view of this, the present inventors consider that a part of a circuit board is cut out and a vibration motor is disposed at the space position as a pre-applied source, and at the center position of the thickness in the height direction of the vibration generating device, The design proposal of thinning was made so that the said circuit board was inserted as a support member, and the vibration generating device was integrated integrally in the center thickness position of a circuit board. However, in a circuit board, many electronic components for forming an electronic circuit are mounted, and each one of them is arranged with the height in the thickness direction of the circuit board so that the thickness of the vibration device is in such a height range. In order to do so, it was necessary to add a function capable of height adjustment to the shape of the holder for attachment.

As mentioned above, the subject of this invention is a vibration which enables the structure which combined maintenance of a device for generating a vibration, height adjustment to the circuit board of the apparatus main body side to mount, and reliable attachment structure with respect to said each problem as mentioned above. An object of the present invention is to provide a holder for attachment of a generation device. Moreover, it aims at making it possible to make both the structure of attachment of a vibration generating device which does not generate an excessive stress or a load with respect to a circuit board, and the holding structure which reliably transmits a vibration to the case on the side of a portable communication device.

As explained above, according to the holder for attachment of Claim 1,

From the circuit board surface at a space position where a circuit board for holding or enclosing a part of the outer circumference of the vibration generating device and mounting the supported vibration generating device main body in the device case is cut out. The heights of both can be fixed by positioning to arbitrary dimensions. Arbitrary height represents the ratio of the height dimension of the vibration generating device which protrudes to an up-down direction across a circuit board, and shows the offset value from both center positions.

Specifically, for example, as shown in Fig. 1 (a), (b), (c), in the step of designing the parts of the circuit board, the height dimension FG from the substrate surface of the circuit board 50, The distribution of EE and HJ can be coordinated with the surrounding electronic components, and can be fixed and fixed by arbitrary height. Thereby, while being thinner in a portable communication device, it can arrange | position in a case without performing downsizing of the vibration generating device, and conventional vibration without changing the size diameter of the weight 6 Vibration force which is not different from the device for generation can be obtained.

Specifically, for example, as shown in FIG. 2 to FIG. 4, a board edge in which the circuit board 50 is cut into the concave groove-shaped rail portion U disposed at an arbitrary position on the outer circumference of the holder 3. Can be inserted to positionally fix the height dimension from the substrate surface to any height. In this case, the basic design of the vibration-generating device main body is common, and simply changes the positions of the concave groove shapes of the power supply terminal 4 and the holder 3 itself attached to the connecting portion 4e, and thus, to various models.

Electrical connection is performed so as to press-contact each other using the elastic force of the attachment member used as a holder.

Specifically, for example, as shown in Figs. 1, 2, and 3, when the vibration generating device 1 is set on the circuit board 50, the rail portion U in the concave groove shape is formed. In this case, by holding the holder 3 in the case of the apparatus main body in the plate thickness direction of the circuit board 50, the power supply terminal 4 is pressed against the power supply land 55 side of the circuit board 50 to reliably generate vibration. It is electrically connected inside the device. In addition, when the vibration generating device 1 is disposed inside the apparatus main body, the contact friction between the feed land 55 of the circuit board 50 and the contact portion of the feed terminal 4 can be reduced, such as poor conduction. It can solve the problem of energization.

Moreover, according to the holder for attachment of Claim 4, in addition to the effect of Claim 1 or 2, and Claim 3,

The attachment member of the holder is used as the rubber-based elastic member or the resin-based insulating member to facilitate assembly to the circuit board 50.

Specifically, as shown in FIG. 4, for example, a portion of the holder 3 (shown as a hatching portion) that holds the outer circumference of the vibration generating device is made of a rubber-based elastic member, and is connected to the circuit board 50. By assembling, the vibration generating device is elastically supported integrally with the circuit board. Accordingly, even if the case itself is subjected to a large impact by dropping or the like, the external shock to the vibration generating device main body can be alleviated, and the vibration force of the vibration generating device can be reliably transmitted to the outside of the main body of the device through the elastic body. have.

Moreover, according to the holder for attachment of Claim 5, in addition to the effect of Claim 1,

Can be fixed by soldering directly to the solder reflow fixing surface 56. At this time, the feed terminal 40 of the vibration generating device can also be connected to the feed land 55 of the circuit board 50 by the solder reflow process.

Can be.

Moreover, according to the holder for attachment of Claim 6, in addition to the effect of Claim 1 or 2, and Claim 5,

Since the holder attachment member is made of a metal member or a spring-like metal member, it becomes a holding structure corresponding to heat of solder reflow.

By soldering to the reflow fixing surface 56, the vibration generating device 1 can be firmly fixed. In addition, in the fixing method by solder reflow, as with other electronic components, the mounting on the circuit board 50 by the automatic machine is arranged using a mounter and heat-treated in the reflow furnace. There is no deformation of the holder itself by heating.

(The best mode for carrying out the invention)

<1st embodiment>

Hereinafter, the structure of 1st Embodiment which concerns on this invention is demonstrated, referring FIGS. In this first embodiment, as one embodiment of the device for generating vibration, a coreless cylindrical vibration motor having an eccentric weight on a rotating shaft will be described as an example. In addition, unlike the conventional motor structure shown in FIG.7 and FIG.8, the structure of the vibration motor 2 of this embodiment is a power supply containing the terminal block 11, as shown in FIG.4 and FIG.9. The whole mechanism part has the motor structure arrange | positioned at the center of the motor main body (near the connection part 4e) by the weight 6 side.

The vibration motor 2 has a weight 6 eccentrically fixed to one end of the rotating shaft 5, and a rotor portion for driving the rotating shaft 5 is supported by the bearing 9 to be inserted into the housing case 13. It is arranged to be stored. The drive mechanism of the motor is largely divided into the housing case 13 on the stator side and the terminal block 11 holding the feed terminal 4, the bearing 9, the magnet 7, and on the other hand, the rotor portion side. Is arranged between the rotary shaft 5, the winding coil 8, and an electrical rectifying mechanism portion 12 required for rotational driving that integrally couples the rotary shaft 5 and the winding coil 8. It is. The weight 6 is shaken and rotated by the rotational operation of the rotor unit, and vibration force is generated.

In FIG. 1, three pattern examples in embodiment of this invention are shown as schematic. As shown to Fig.1 (a), (b), (c), the attachment position of the vibration generating device 1 is a distribution of height dimension FG, EE, HJ from the board surface of the circuit board 50. It determines by synchronizing with surrounding electronic components, and positioning fixed to arbitrary height. The arrangement position of these three patterns makes each holding | maintenance part a common inner diameter shape, and changes the manufacturing design design on the holder 3 side by changing the position of the concave groove-shaped rail part of the outer peripheral part of the holder 3. This is possible and correspondence of the holder 3 side is possible also in various various specifications. Of course, the vibration motor used in the vibration generating device 1 can use a common model and can share the main part.

As a result, compared with the conventional attachment method, the portable communication device can be made thinner, and the vibration generating device can be placed in the case of the main body of the device to be mounted without further minimizing the vibration generating device. The vibration force which is not different from the conventional vibration motor size can be obtained, without changing the size diameter of the weight 6 to be made.

2 and 3 show the direction when the vibration generating device 1 is inserted into the circuit board 50. In addition, the circuit board 50 and the vibration generating part are inserted in both sides of the cutout of the circuit board 50 by inserting the concave groove-shaped rail portion U portion of the holder 3 along the direction of the arrow. The device 1 is fixed.

The outer shape of the holder 3 is formed so as to substantially surround the outer circumferential portion of the vibrating motor, for example, as shown by a hatching portion in FIG. 4, and is configured such that a part of the motor main body and a weight 6 portion protrude. have. In the state where the holder 3 is inserted into the circuit board 50, as shown in FIG. 1, the power supply terminal 4 is disposed on one side of the rail portion U in the concave groove shape, and the circuit It is sandwiched together with the substrate 50.

In addition, the whole holder 3 is clamped and hold | maintained in the up-down direction of the surface of the circuit board 50 by the case of 2 parts of the apparatus main body side which is not shown in figure. In order to actually hold the holder 3, the nonuniformity of the plate thickness of the circuit board 50, the nonuniformity of the concave groove dimension of the rail portion U of the holder 3, and the like affect the dimensions of the components to be combined. In this embodiment, the material of the holder 3 is made of a rubber-based elastic member. In this embodiment, the adaptability and ease of insertion with the circuit board 50 are considered, and the pressing to the power supply terminal 4 is performed. To keep the power constant.

<2nd embodiment>

Next, the structure of 2nd Embodiment which concerns on this invention is demonstrated, referring FIG. 5 and FIG. In this 2nd Embodiment, the general cylindrical vibration motor provided with the eccentric weight in a rotating shaft as an aspect of a device for vibration generation is demonstrated, for example. In addition, the structure of the vibration motor of this embodiment is a type with the feed mechanism part located in the opposite side to the weight 60, and the feed terminal 40 sticks out axially from the cylindrical end side of a motor main body.

As shown in FIG. 5, there is a notch space on the circuit board 50 side, and both sides of the board edge correspond to the solderable reflow fixing surface 56 and the power supply terminal 40 that can be soldered. The power supply land 55 is disposed on the same surface of the circuit board 50. Moreover, the vibration motor 20 side is a form in which the holder shape press-molded the metal thin plate, and formed the wing-shaped seating part 30R in the cylindrical outer peripheral part of a 2 division tank, and this holder ( The vibration motor 20 held by 30 is set at a position where the circuit board 50 is cut out. In this case, it inserts in a direction different from the said 1st Embodiment. In other words, the vibration motor 20 can be set so as to be separated from the substrate surface as shown in the drawing. Thereby, the automation line by a mounter apparatus becomes possible, for example in the assembly process at the time of mass production.

Of course, a cream soldering layer is provided in advance on the solder reflow fixing surface 56 and the feeding land 55 of the circuit board 50, and when the vibration motor 20 is mounted on the circuit board 50, the circuit board 50 is provided. The phase is fixed. The temporarily fixed state is shown in FIG. At this time, the height dimension from the board | substrate surface of the circuit board 50 can be adjusted with the arrangement position of the said mounting part 30R. The circuit board 50 and the vibration motor 20 are joined and fixed through the holder 30 by being put into a solder reflow furnace and heat treated while being in this state.

Naturally, the inside of the solder reflow furnace is a high temperature condition of 200 ° C. or higher, and since the temperature of the vibration motor 20 itself in the reflow furnace during processing is also subjected to a high temperature, each component of the vibration motor 20 Needs heat resistance. For the same reason, the material of the holder 30 also basically uses a SUS-based metal member. In addition, although not shown in detail, the heat-resistant elastic sheet 36 may be interposed between the holder 30 and the vibration motor main body (housing case outer periphery) and serve as a heat insulating effect.

In the case of this second embodiment, since the vibration motor 20 is directly fixed by soldering via the metal holder 30 to the circuit board 50, the transmission of the vibration to the case of the apparatus main body side is a circuit board. Through (50). In addition, the holder shape may not necessarily cover the whole vibration motor 20, and may be a shape which couples the vibration motor 20 to the lower part. In addition, as long as the arrangement relationship between the electric circuit board 50 and the vibration motor 20 can be maintained, it is not necessary to mount the holder portion on the vibration motor 20 side, and it is vibrated on the holder portion disposed on the circuit board 50 side. Even if the motor 20 is fitted and attached, the same object and effect can be acquired.

Moreover, this invention can be variously changed based on the technical idea of embodiment shown above, and in a vibration generating mechanism, it is not limited to the cylindrical vibration motor of this embodiment, but the flat vibration motor which has a rotating shaft or a fixed shaft. Needless to say, the present invention can be applied to various vibration generating devices such as a multi-function device, a vibration linear device, or a vibration actuator.
