Description

Shock vibration generating device and application device using same

The present invention relates to an apparatus for generating shock vibration, in particular, a shock that can be used as an interface means for various signals and communication between various devices such as multimedia devices, game machines, communication devices, and users by generating shock vibration freely. The invention relates to the invention of a vibration device.

In general, the vibration generating device, for example, is embedded in an electronic device such as a mobile phone to perform the function of notifying the incoming or short message arrival by vibrating instead of ringing, the built-in game operation device generates a vibration effect sound It is used to increase the enjoyment or interest to give the user a sense of reality.

In addition, with the development of technology, not only communication, but also multimedia playback and transmission, the Internet, games, etc. can be enjoyed by a mobile phone; Internet and video playback are also possible with game machines; Video players can play music, videos, and play Internet and games. Most of these devices have a built-in vibration generator, and the interest is doubled, and the conventional vibration generator mainly uses a small vibration motor.

The vibration motor is generally divided into a flat type vibration motor and a bar type vibration motor as shown in FIGS. 1 and 2 according to the shape thereof. The conventional vibration motor mainly uses the eccentric vibration by rotating the eccentric weight.

FIG. 1 is a schematic configuration diagram of a conventional flat vibration motor disclosed in Korean Patent No. 0389631, which generates a rotational force by electric current flowing through a coil 6 and a magnetic field of a permanent magnet 3 to produce a coil 6 and a bearing 7. Eccentric rotation unit 2, etc.) is rotated about the rotation axis (1) to generate a vibration caused by the eccentricity, the current flowing through the coil 6 is the rotational force by the commutator 5 and the brush (4) It is controlled to occur smoothly. The vibration is generated when the eccentric rotation part 2 rotates when power is applied to the motor, and stops when the power is cut off.

In addition, Figure 2 is a schematic configuration diagram of a conventional rod-type vibration motor disclosed in Korean Patent Laid-Open No. 2005-0086150, which includes a rotating shaft 20, coil 19, commutator 18, eccentric weight 13 The rotating part rotates by the action of the current flowing through the permanent magnet 17 and the coil 19 to generate vibration by the eccentric weight 13, and rotates by the commutator 18 and the brush 16 to generate a smooth rotational force. The current supplied to the coil 19 is controlled. The vibration is generated when the eccentric weight 13 is rotated by the rotation of the rotating part when the power is applied to the motor and stops when the power is cut off.

3 is a schematic configuration diagram of a vibrator using a reciprocating motion of a conventional flat vibration motor disclosed in Korean Patent Laid-Open Publication No. 2005-0122101, in which a weight 34 is fixed to a spring 31 to a coil 35. When a current is applied, a magnetic circuit leading to the permanent magnet 36, the yoke 32, and the coil 35 is formed, and the weight is increased by the attractive force and repulsive force between the permanent magnet 36 and the winding coil 35. The portion including the weight 34 is suspended in the spring (31). When the current direction is applied to the coil 35 while changing the current direction, the weight 34 moves up and down to generate vibration. In the case of the vibration generating apparatus using the rotation of the conventional eccentric member as described above is using the rotation of the motor. However, since the motor speed is determined by the design of the motor, the vibration generator generates the vibration by rotating the motor only for a predetermined time of applying a current. Therefore, on / off control of vibration generation is possible, but it is not suitable for freely controlling vibration frequency or magnitude, and it is very difficult to generate single vibration.

In addition, Figure 4 is a schematic configuration diagram of a device having a structure capable of shock vibration in the prior art disclosed in Korean Patent No. 1084715, and controls the direction of the current flowing through the coil 41 and the magnet facing the coil By using the attraction force and the repulsive force generated between the 42, the magnet 42 hits the coil 41 and the support plate 43 to generate a vibration, the magnet 42 acts as a weight weight to reciprocate . In the case of the reciprocating motion type, the vibration intensity is small compared to the volume, and there is a limit to use in the resonance region.

Figure 5 shows an example of the vibration amount adjustment method in the disclosed conventional portable communication terminal. In FIG. 5, the ON / OFF signal coding unit 50 of the portable communication terminal generates a signal to be applied to the vibration motor 52, and according to the signal, the switch unit 54 generates the vibration motor ( Since the vibration motor 52 is rotated / stopped by turning on / off a voltage applied to 52), vibration is generated while voltage is applied, and vibration is not generated when voltage is not applied.

6 shows a configuration of a game device of the prior art disclosed in Korean Patent No. 0563391. As shown in FIG. 6, an image output device 64 is connected to a game machine main body 60 that performs game content and controls the game, and a game is executed through a plurality of operation buttons, and transmits data with the game machine main body. And a game operation device 62 for receiving is connected. The game operating device includes a vibration motor 66 which is a vibration generating device and is configured to rotate at a high speed and generate vibration when a voltage is applied according to a signal generated from the main body 60.

In the related art, the vibration adjustment in a portable terminal, a game operation device, or the like has no technology other than a method of generating a difference in vibration by changing a voltage and changing a motor speed.

In general, in the prior art, vibration is generated using vibration caused by rotating the eccentric weight body with the vibration motor or vibration caused by the reciprocating motion of the weight body in the resonance region. However, when the rotation of the eccentric weight body is used, the vibration amount is small during the starting time when the motor starts and reaches the normal speed, so that it is difficult to use it practically, and it is difficult to generate a short time vibration within the starting time. By rotating at a speed, it is very difficult to adjust the period of vibration, the number of vibrations, and the like. Moreover, it is extremely difficult to generate a single vibration in which the vibration occurs momentarily.

In addition, the conventional reciprocating vibration motor is provided with a drive control circuit to adjust the frequency in a limited range, but the vibration strength is small compared to the volume, and the magnet becomes large, resulting in high cost. In addition, in the conventional reciprocating vibration motor, in order to increase the vibration intensity, the power consumption is greatly increased, so there is a limitation to use in the resonance region, and thus the use region is limited. . In addition, since the resonant motion makes it difficult to adjust the vibration period, frequency, and the like, in the related art, only a power source is turned on and off in a resonant region to drive a reciprocating vibration motor.

As described above, the vibration adjustment in the prior art uses vibration generation On / Off due to a change in rotational speed due to voltage adjustment or on / off of a power supply, and thus generates a period of vibration. It is difficult to adjust the number of vibrations and the like, and there are disadvantages such as a phenomenon that the remaining vibrations gradually disappear even after the power is turned off.

In addition, it is difficult to generate a single vibration (vibration) and difficult to create sharp and strong instantaneous vibration, such as shock vibration.

The present invention has been made to solve the above-mentioned conventional problems, and generates a sharp and strong vibration, that is, the impact vibration (Impactive Vibration) with a simple configuration, the game device by freely adjusting the frequency and frequency of occurrence of the impact vibration The purpose of the present invention is to provide a shock vibration generating device and an application device using the same, which can increase the interest and realism of a user of a portable communication terminal or a multimedia reproducing device such as a mobile phone.

In this case, since the protrusion 74 may be configured to rotate together with the rotation part, the protrusion 74 may be coupled to another component that can rotate. However, the protrusion 74 should be configured to be separated from the stopper 79 to be described later.

In addition, as shown by the solid line and the dotted line shown in FIG. 13 mentioned later, the space | gap whose magnetic flux flows in the direction of a rotation axis, ie, the direction parallel to a rotation axis, is called the space | gap of an axial direction. In rotating electric machines, that is, electric motors or generators, air gaps are formed between a fixed part and a rotating part to generate a flow of magnetic flux, and the air gaps are in the radial direction and in the axial direction.

8A and 8B are conceptual views for explaining the operation of the shock vibration generating apparatus according to an embodiment of the present invention illustrated in FIG. As shown in FIG. 8A, when the rotary part is rotated counterclockwise, the protrusion 74 rotates counterclockwise together with the rotary case 72 to contact the stopper 79 at the rotational speed thereof.

In this case, since the energy of the rotating part is rotated and consumed by the collision of the protrusion 74 and the stopper 79, the inertia force is lost, so that the rotating part is easily reversed. In addition, since the shock vibration occurs due to the impact of the stopper 79 and the protrusion 74, the vibration may be instantaneously and strongly generated.

The timing and period of occurrence of the collision between the protrusion 74 and the stopper 79 are adjusted by the rotation timing, the reciprocation rotation period, and the rotation speed of the rotating part, and thus, the vibration of the impact may be freely adjusted using the rotation period.
