Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vibration generator for transmitting an incoming signal to a user by vibration provided in a small portable wireless device typified by a pager or a portable telephone. The present invention relates to a vibration generation device that gives a strong bodily sensation to a user by ascending, descending, and reversing the weight around a support column to generate a notice of an incoming call of a wireless device.

[0002]

2. Description of the Related Art Generally, a small portable radio device represented by a pager or a portable telephone is provided with a vibration generating device for transmitting an incoming signal to a user not by voice but by vibration. Here, a conventional vibration generator provided in this type of portable wireless device will be described with reference to FIG. FIG. 4 is a schematic external perspective view showing a vibration generator provided in a conventional portable wireless device such as a pager.

As shown in FIG. 1, the conventional vibration generating device includes a drive motor 101 and a weight (counter wit) 102 which is driven to rotate by the drive motor 101, and the weight 102 is connected via a shaft 103. It is provided in a housing of a portable wireless device such as a pager (not shown) while being attached to the drive motor 101.

When the wireless device receives a signal from the outside, the drive motor 1 is driven by electric power from a control unit (not shown).
01 is driven to rotate the weight 102 in one predetermined direction via the shaft 103, and the rotation of the weight 102 causes eccentric vibration. This eccentric vibration is felt by the user via the housing of the wireless device, and the user can know the incoming signal without voice.

[0005]

However, in such a conventional vibration generator, the weight rotated by the drive motor rotates only in one direction, so that the vibration component generated is only one plane. The bodily sensation of the user becomes weak, especially when the user is walking or working.
Depending on the situation, there may be a case where vibration cannot be experienced, and there is a problem that an incoming call of the wireless device cannot be reliably transmitted to the user side.

In addition to the vibration generating device that generates vibration by rotating the weight, a voice coil such as a "payer vibration actuator" described in Japanese Patent Application Laid-Open No. 9-308209 may be used. There has been proposed an apparatus that generates vibration by moving a mold damper up and down to collide with a housing. However, such a vertical collision type vibration generating device has a problem that although a vertical vibration component is generated, there is no horizontal vibration component, and the vibration is weak as a bodily sensation for the user.

The present invention has been proposed in order to solve the problems of the prior art, and provides a user with a weight that generates rotational vibration by moving the weight up and down and forward / reverse around a column. An object of the present invention is to provide a vibration generating device that gives a strong bodily sensation and reliably notifies an incoming call of a wireless device.

[0008]

According to a first aspect of the present invention, there is provided a vibration generating apparatus provided in a wireless device, wherein a predetermined signal is input from the wireless device to generate a vibration. Helical vibration generator
A column having a groove formed on the outer periphery along the axial direction;
Helical groove to engage with the part, eccentric rotation of the column
A magnet that moves up and down along the column while rotating as an axis
A weight provided on one of the columns and the radio
Magnetic force of the magnet toward the weight based on the signal from the vessel
Drive to intermittently generate a magnetic force that repels
Due to the intermittent occurrence of magnetic force, the weight is moved along the support.
And a main urging means for moving up and down .

According to the second aspect, the other of the columns is
Provided, and raised or lowered by being biased by the main biasing means.
The weight that has fallen is pushed back to the main biasing means side.
A biasing means, wherein the primary biasing means and the secondary biasing means are biased.
The weight causes the weight to move along the spiral groove of the column.
Thus, the vertical movement and the normal / reverse rotation are repeated .

According to a third aspect of the present invention, the coil of the main biasing means generates a magnetic force intermittently toward the weight magnet by a pulse signal from the wireless device.

According to the vibration generating apparatus of the present invention having the above-described structure, a spirally extending groove is provided on a column on which the weight is rotatably mounted, and the weight is moved from the main biasing means and the secondary biasing means. The weight is biased toward both ends of the column by two biasing means.
While going up and down along the column, the normal and reverse rotation is repeated around the column.

As a result, the weight generates eccentric vibration due to forward and reverse rotation about the column in the horizontal direction, and also generates vertical vibration by moving the column up and down. Is compounded to give the user a strong bodily sensation. In addition, the rotation and lifting movement of the weight are divided into two cases: forward rotation while raising the support, and reverse rotation while lowering the support.
Since the repetition is performed alternately, the user can feel the vibration more strongly. Therefore, compared with the conventional bodily sensation vibration caused by a single rotation in only one direction, the arrival of a signal can be transmitted to the user without fail.

According to a fourth aspect of the present invention, the main urging means and the sub urging means have different urging forces.

According to such a structure, the biasing force of the main biasing means and the biasing force of the biasing means are made different from each other, so that the weight moves forward while moving up the support, and the reverse movement moves while moving down the support. In this case, two vibrations having different amplitudes and vibration times can be generated, and the different vibrations are alternately and repeatedly generated, so that the user's sensation of the vibrations can be further enhanced.

Further, in claim 5 , the follower urging means has the same configuration as the main urging means. In this way, the follower biasing means also has a weight that has a magnet and a coil that generates a repulsive magnetic force, thereby making it possible to further strengthen the forward / reverse and vertical movements of the weight, and to generate stronger vibration. Therefore, the user's bodily vibration can be enhanced. In addition, since the space can be omitted as compared with the case where the biasing means is constituted by a spring, it is possible to reduce the thickness of the entire vibration generator. In addition, claim 6
As shown, in claim 1 to claim 5, the biasing means
May be composed of an elastic member.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the vibration generator according to the present invention will be described below with reference to FIGS. FIG. 1 is a schematic sectional front view of a main part showing a vibration generator according to an embodiment of the present invention. FIG. 2 is a schematic external perspective view showing a weight of the vibration generator according to the embodiment of the present invention shown in FIG. FIG. 3 is an explanatory diagram showing a pulse signal input to the vibration generator of the present embodiment.

The vibration generator 1 of the present embodiment shown in FIG.
Is provided in a main body of a wireless device such as a pager (not shown). When the wireless device receives a wireless signal from the outside, the weight 20 is rotated by a predetermined signal input from the wireless device side to cause eccentric vibration. It is a device that generates and informs the user of the incoming signal. As shown in FIG. 1, the vibration generating device 1 includes a housing 1a provided in a main body of the wireless device.
In the housing 1a, there are provided a column 10 and a weight 20 which is rotatably mounted with the column 10 as an eccentric rotation axis and generates eccentric vibration.

As shown in FIG. 1, the column 10 has a housing 1a.
The upper and lower ends are fixed to the upper and lower surfaces of the inner wall of the housing 1a, respectively. A groove 12 extending spirally along the axial direction is formed on the outer periphery of the column 10.

A weight 2 is provided at the lower end of the support 10.
A spacer base 11 is provided which is in contact with the lower surface side of the housing 1, and functions as a spacer in which the weight 20 attached to the column 10 stops at a predetermined position facing a coil 30 described below provided below the housing 1 a. doing. In addition, this support 1
A spring 40 is wound around the outer periphery of the upper end of the zero.
As will be described later, when the spring 40 is compressed by the weight 20, the weight 20 urges the weight 20 toward the coil 30 below the housing 1a, and constitutes a biasing means for pushing back .

On the other hand, as shown in FIG. 2, the weight 20 rotatably supported by the column 10 has a through hole 21 through which the column 10 passes through on one side, and the through hole 21 having the through hole 21 as a center point. The support 10 is formed in a substantially fan shape that extends in the direction around the axis. The fan-shaped weight 20 rotates the support 10 with the eccentric rotation axis to generate eccentric vibration.

Although the weight 20 has a substantially fan shape in the present embodiment, the weight is not particularly limited to a fan shape, and eccentric vibration is generated by rotating the support column 10 as a rotation axis. Anything should do. That is, as long as the weight 20 rotates with the support 10 as an eccentric rotation axis, eccentric vibration can be generated by rotation. For example, the weight 20 is formed as an eccentric disk shape or an eccentric semicircle shape with the support 10 as a rotation axis. Is also good.

A spirally formed engaging portion movably engaged with a groove 12 formed on the outer periphery of the column 10 is provided on the inner periphery of the through hole 21 through which the column 10 of the weight 20 passes. 22 are provided. The weight 20 has a magnet disposed at least in a portion of the fan-shaped plate surface opposed to the coil 30 so as to repel magnetic force from a coil 30 serving as a main biasing means described later. Here, the entire weight 20 is formed by a magnet.

As shown in FIG. 1, the weight 20 is placed in the axial direction of the column 10 (in the present embodiment, on the lower side of the housing 1a) by a predetermined signal from a control unit of a wireless device (not shown). a coil 30 as the main urging means for urging the), is biased by the coil 30, it has increased
A spring 40 is provided as urging means for urging the weight 20 toward the coil 30 and pushing it back .

The coil 30 is provided with a weight 2 below the housing 1a.
It is disposed so as to face one surface (the lower surface shown in FIG. 1) of the fan-shaped plate surface of No. 0. In the present embodiment, the coil 30 is formed annularly around the axis centered on the column 10 of the housing 1a so as to always face the weight 20 rotating around the axis of the column 10. The coil 30 is not limited to the annular coil 30 of the present embodiment, as long as the coil 30 always faces the weight 20 that rotates around the axis of the column 10.
For example, a plurality of coils may be provided around the axis of the support 10.

The coil 30 is connected to a control unit on the main unit side of the wireless device (not shown). When the wireless device receives a signal from the outside, the coil 30 is connected via the control unit.
A predetermined signal is input to
A magnetic force of the same polarity repelling the magnet of the weight 20 toward 0 is generated intermittently.

Here, in the present embodiment, the pulse signal shown in FIG. 3 is input from the wireless device to the coil 30, and the coil 30 moves toward the weight when the input pulse signal is at the H level. A magnetic force is generated, and no magnetic force is generated at the L level. As a result, the coil 30 generates a magnetic force intermittently on the weight 20, thereby repelling the weight 20 to the upper side of the housing 1a and energizing the weight.

On the other hand, a spring 40 serving as a biasing means is provided.
Is wound around the upper end of the support 10 in the drawing.
Then, the weight 20 is compressed by the weight 20 rotating and moving upward in the axial direction of the column 10, and the weight 20 is urged toward the coil 30 again by the elastic force. As shown in FIG. 1, the spring 40 is wound around the upper end of the column 10, and the weight 20 is wound at the lower end of the spring 40.
And is compressed in contact with the upper surface of the main body.

Here, as shown in FIG. 1, at the lower end of the spring 40 of the present embodiment, a contact plate 41 disposed in parallel with the upper surface of the weight 20 is disposed. The surface 41 is in parallel surface contact with the upper surface of the weight 20 that has risen on the column 10. Thus, the resilient force of the compressed spring 40 is transmitted uniformly to the weight 20 via the contact plate 41.

In the present embodiment, the biasing force of the spring 40 and the coil 30 on the weight 20 is different. When the biasing force of the spring 40 and the coil 30 are made different, the weight 20 vibrates forward while moving up the support 10 and the weight 20 vibrates reversely while moving down the support 10. Since vibration is generated, different vibrations are alternately and repeatedly generated, so that the user's bodily sensation of vibration can be enhanced.

The supporting means constituted by the spring 40 is urged from the main urging means side to support the support 1.
Any means for urging the weight 20 that has moved to one end of the zero in the opposite direction is not limited to the spring 40 of the present embodiment, and may be replaced with a well-known elastic member such as a leaf spring. it can.

In the present embodiment, the two biasing means including the spring 40 and the coil 30 are set in the vertical direction (vertical direction) of the apparatus, but the weights 20 are attached to the one side and the other side along the column 10. As long as it is energized, the energizing direction can of course be a direction other than the up-down direction, for example, the left-right direction (horizontal direction), depending on the structure of the wireless device or the vibration generating device.

Next, the operation of the vibration generator of the present embodiment having the above-described configuration will be described. First, when the wireless device receives a wireless signal from the outside, a predetermined pulse signal is output from the control unit (not shown) of the wireless device and input to the coil 30 as shown in FIG.

When the input pulse signal is at the H level (see FIG. 3),
A magnetic force having the same polarity as the magnet of the weight 20 is generated toward the weight 20. As a result, the weight 20 is urged to the upper side of the housing 1a against the same magnetic force generated intermittently from the coil 30, so that the strut with which the engaging portion 22 of the through hole 21 is engaged. Along the ten spiral grooves 12, it moves above the support column 10 while rotating (forward rotation) in one direction.

When the weight 20 that has moved while rotating toward the upper end of the column 10 comes to a position where it comes into contact with the contact plate 41 of the spring 40, the weight 20 rises while further compressing the spring 40. In this state, when the pulse signal input to the coil 30 becomes L level (see FIG. 3), the coil 3
Since the magnetic force from zero stops and the urging force against the weight 20 is lost, the weight 20 is urged toward the coil 30 by the resilient force of the compressed spring 40, and moves along the spiral groove 12 of the support 10. Then, the column 10 is lowered while rotating (reversely rotating) in the opposite direction to the direction in which the column is raised.

The lowered weight 20 rebounds against the magnetic force of the coil 30 intermittently generated by the pulse signal, rotates again along the column 10, and lowers again by the elastic force of the spring 40. At this time, since the biasing forces of the coil 30 and the spring 40 are different, the amplitude and the vibration time are different between the case where the weight 20 moves forward while moving up the support 10 and the case where the weight 20 moves reversely while moving down the support 10. Two vibrations occur.

In this manner, the weight 20 is formed in the spiral groove 12 of the support 10 while the pulse signal is being input.
Up and down and forward and reverse rotations along. As a result, the weight 20 generates not only eccentric vibration due to normal / reverse rotation about the support 10 but also vibration due to up-and-down motion that moves up and down along the support 10, and the two different vibrations are combined to form a housing. The user can experience the signal reception via the wireless communication device 1a and the housing (not shown) of the wireless device, so that the user can know the arrival of the signal.

As described above, according to the vibration generating apparatus of the present embodiment, the spirally extending groove 12 is provided on the support 10 on which the weight 20 is rotatably mounted, and the weight 20 is biased by the coil 30 and the spring 40. The weight 20 is urged toward the both ends of the column 10 by means.
Will repeat forward / reverse rotation around the column 10 while moving up and down along the column 10.

As a result, the weight 20 generates not only eccentric vibration due to forward and reverse rotation about the column 10 in the horizontal direction, but also vertical vibration by moving the column 10 up and down. The combination of the two vibrations gives the user a strong bodily sensation. In addition, the rotation and lifting movement of the weight 20 are alternately and repeatedly performed between a case where the rotating motion is forward while moving up the column 10 and a case where the rotating motion is reversed while moving down the column 10. Can feel the vibration more strongly. Therefore, compared with the conventional bodily sensation vibration caused by a single rotation in only one direction, the arrival of a signal can be transmitted to the user without fail.

The vibration generator according to the present invention is not limited to the embodiment described above, and various modifications can be made within the scope of the present invention. For example, the main urging means and the sub urging means for urging the weight toward the upper and lower ends of the column are at least one of which constitutes the main urging means for urging the weight in response to a signal received by the wireless device. It is only necessary that the secondary urging means has the same configuration as the main urging means, and both of the two urging means are the main urging means (coil 30 in the above embodiment).

As described above, by using a coil having a magnet and generating a repulsive magnetic force with respect to the weight provided with the magnet, the forward / reverse rotation and the vertical movement of the weight can be further increased, and the stronger vibration can be obtained. Is generated, and the bodily vibration of the user can be enhanced. In addition, since the space can be omitted as compared with the case where the biasing means is constituted by a spring, it is possible to reduce the thickness of the entire vibration generator.

As described above, the weight attached to the column may have any shape and form as long as it generates eccentric vibration by eccentric rotation about the column. That is, as described above, in the above embodiment, the weight is formed in a plate-like member that spreads substantially in a fan shape. However, in addition to this, for example, a semi-disc shape or a semi-cylindrical shape may be used.

[0042]

As described above, according to the vibration generating apparatus of the present invention, the weight for generating the rotational vibration is raised and lowered about the support column, and is rotated in the normal and reverse directions to give the user a strong bodily sensational vibration and to provide the radio equipment. Can be surely notified.
