Impulse pattern generator {THE APPARATUS FOR GENERATING IMPULSE PATTERN}

The present invention relates to an apparatus for generating an impulse pattern, and more particularly, an impulse capable of giving a user a feeling of click by changing the frequency and strength of a pulse according to whether the connection signal increases or decreases according to a user's touch input. It relates to a pattern generator.

In order to effectively convey various information transmitted through the ubiquitous network environment to the user through mobile devices, the five senses of human beings have been transmitted. However, the mobile devices that we have encountered so far depend mainly on vision and hearing. .

Recently, however, research on technology for transmitting touch, which is another very important sense along with vision and hearing, has been actively conducted, and a device using such touch is called a haptic device.

Haptic devices are used in various fields such as virtual reality, simulation, wearable computers, robotics, and medical applications, and are also known as haptic interfaces.

These haptic devices use force feedback devices that deliver physical forces to muscles and joints, as well as mechano receptors built into the skin to stimulate skin such as texture, temperature, pressure, vibration, and pain. It is divided into a tactile device (or a tactile display device) that transmits the light.

Here, it is important that the haptic device has a tactile technology for realizing a realistic force such as the texture of an actual object to the user by skin irritation.

Recently, electronic devices such as mobile phones, for example, have delivered visual information as well as auditory information such as SKT's "3G +" and KTF's "SHOW". As a result, a larger display is required, and thus, a mobile phone having a touch screen form without a control button such as a "haptic phone or touch web phone" is being changed.

As there is no operation button provided in an electronic device such as a conventional mobile phone, users operate a mobile phone using only a touch screen. As a result, the user touches the touch screen when the user operates the touch screen. It's hard to recognize that it's done properly, which increases the incidence of false touches on the touch screen.

In order to overcome the drawbacks described above, when the touch screen is touched and manipulated, the vibration motor is driven to generate vibration, or the touch screen itself is shaken.

However, when the vibration motor is driven when the touch screen is operated to generate vibration, the user may not feel the vibration vividly and only have to implement one type of vibration. There was a limit that could not deliver the impact amount.

The present invention has been made in view of the above problems, and determines the point of time of increase or decrease of a connection signal according to a user's touch input, and can give a user a feeling of click by changing the frequency and strength of a pulse. Its purpose is to provide an impulse pattern generator.

In order to achieve the above technical problem, the present invention relates to an impulse pattern generating apparatus, the touch sensing unit for detecting a user's contact, and transmitting the impact amount received from the actuator to the user; A controller configured to apply electrical energy to an actuator based on a user's touch signal detected through the touch detector; And an actuator receiving periodic electric energy from the controller and transferring a specific impact amount to the contact sensor. Characterized in that it comprises a.

According to the present invention as described above, by outputting a pulse having a different frequency and strength of the power periodically, there is an effect that can generate a variety of types of impulse.

Specific features and advantages of the present invention will become more apparent from the following detailed description based on the accompanying drawings. In the meantime, when it is determined that the detailed description of the known functions and configurations related to the present invention may unnecessarily obscure the subject matter of the present invention, it should be noted that the detailed description is omitted.

Hereinafter, with reference to the accompanying drawings will be described in detail the present invention.

The impulse pattern generator according to the present invention will be described with reference to FIGS. 1 to 10.

1 is an overall configuration diagram of an impulse pattern generating apparatus according to the present invention, and includes a touch sensing unit 100, a controller 200, and an actuator 300 as shown.

The touch sensing unit 100 detects a user's touch and performs a function of transmitting an impact amount received from the actuator 300 to the user.

In this case, the touch sensing unit 100 may be variously set as a touch sensor capable of detecting the presence or intensity of the touch or a touch panel sensing the contacted position (relative coordinate) in the panel.

In addition, the controller 200 performs a function of applying electrical energy to the actuator 300 based on the user's contact signal detected by the touch sensor 100.

Specifically, the control unit 200 determines the frequency of the pulse by determining the time of increase or decrease of the user's touch signal detected by the touch sensing unit 100, and the intensity (force) of the pulse through the voltage intensity and duty By determining the, pulses having a specific frequency and intensity (hereinafter referred to as 'shock pulses') are generated and applied to the actuator 300.

On the other hand, Figures 2 and 3 is an exemplary view showing the appearance of a shock pulse having a different frequency and intensity (force) according to the user contact signal, as shown in Figure 2, the control unit 200, Can generate a shock pulse (first shock pulse) of a predetermined intensity at the moment (a) when the user presses the touch sensing unit 100 (the time when the user touch signal increases). A relatively weak shock pulse (second shock pulse) may be generated in comparison with the moment (a) of pressing the part 100, and at the moment (c) (a time point at which the contact signal decreases) when released from the touch sensing unit 100. In addition, it may be set to generate a shock pulse (first shock pulse) of the same intensity as the moment (a) of pressing the contact detection unit 100.

In addition, as shown in Figure 3, the control unit 200 is a shock pulse (second shock pulse) of a predetermined intensity at the moment (d) (the time when the user touch signal is increased) the user presses the touch sensor (100). At the moment (e) of being finally pressed and clicked, a relatively strong shock pulse (first shock pulse) may be generated as compared with the moment (d) of pressing the touch sensor 100.

On the other hand, the control unit 200 applies the 'shock pulse' periodically to the actuator 300, and will be described in detail below, but the 'shock pulse' causes the actuator 300 to shock or inertial vibration.

That is, as shown in (a) and (c) of FIG. 2, the shock pulse (first shock pulse) at the point of time when the user's contact signal increases and decreases, causes the actuator 300 to vibrate, and FIG. ), The impact pulse (second shock pulse) at the moment of pressing the contact sensing unit 100 causes the actuator to inertia vibrate.

In addition, the actuator 300 receives a periodic shock pulse (electrical energy) from the controller 200 and transmits a specific shock amount to the contact sensor, as shown in FIG. 4, as illustrated in FIG. 4. It includes a motion conversion means 310 for converting the shock pulse applied from the kinetic energy and reciprocating means 320 for receiving the kinetic energy converted from the motion conversion means 310 to reciprocate.

As shown in FIG. 4, the motion converting means 310 includes a magnetic force generating unit 311 made of a magnetic material and an upper portion of the magnetic force generating unit 311 so as to generate magnetic force when the impact pulse is applied from the control unit 200. It is fixed spaced apart in the, and includes an elastic providing unit 312 to provide an elastic force in the vertical direction.

In addition, the reciprocating means 320 is completely risen completely apart from the magnetic force generating unit 311 when supplying a periodic shock pulse (first impact pulse) having a voltage strength or duty exceeding the reference value to the magnetic force generating unit 311 Periodic shock pulses (second shock pulses) are generated by repeating the state and the complete falling state hitting the upper surface of the magnetic force generating unit 311 and having a voltage strength and duty of less than the reference value in the magnetic force generating unit 311 ) When supplied, the permanent magnet 321 which generates inertial vibrations by repeating the partially elevated state spaced apart from the magnetic force generating unit 311 and the partially lowered state approaching the upper surface of the magnetic force generating unit 311, and the permanent It is fixed to one side of the magnet 321, and includes a contactor 322 that rises or falls together according to the movement of the permanent magnet 321.

Specifically, the magnetic force generating unit 311 of the motion conversion means 310 is a component that generates a magnetic force when supplied with electrical energy such as an impact pulse from the outside, made of a magnetic body. For example, the magnetic force generating unit 311 may be composed of a general solenoid coil. In this embodiment, it consists of the bobbinless solenoid coil of the form which opened the center.

Here, the magnetic force generating unit 311 is the upper pole is S pole and the lower pole is N pole when supplying voltage in the forward direction, the upper pole is N pole and the lower pole is S pole when supplying voltage in the reverse direction. Of course, the polarity can be configured in reverse.

In addition, the elastic providing unit 312 is spaced apart and fixed to the upper portion of the magnetic force generating unit 311, and provides an elastic force in the vertical direction.

Here, the elastic providing unit 312 is not shown, but is formed in a plate shape, the fixing hole for the fixed contact through the contactor 322 and a slot for elastic deformation is formed around the fixing hole, by the slot It is formed to provide an elastic force in the vertical direction about the fixing hole.

The permanent magnet 321 of the reciprocating means 320 is configured to be connected to the elastic providing unit 312, when the shock pulse is not supplied to the magnetic force generating unit 311, the upper surface of the magnetic force generating unit 311 by its own magnetic force As it descends to be attached to or close to, the elastic providing unit 312 is to be in a state holding the elastic restoring force. In the present embodiment, the permanent magnet 321 may be configured as the upper pole of the N pole and the lower pole of the S pole.

As shown in FIG. 5, when a signal of "a1" having a voltage of 0 is sent to the magnetic force generating unit 311, the attraction force between the permanent magnet 321 and the magnetic force generating unit 311 is elastic providing unit 312. When greater than the elastic force of the) is the permanent magnet 321 is attached to the upper surface of the magnetic force generating unit 311, the attraction between the permanent magnet 321 and the magnetic force generating unit 311 and the elasticity providing unit 312 When the force between the elastic force of the balance is maintained in a balance with each other, the permanent magnet 321 may be in a state close to the upper surface of the magnetic force generating unit (311).

Hereinafter, the shock vibration and the inertial vibration of the permanent magnet 321 will be described. First, the shock vibration of the permanent magnets 321 will be described. As shown in FIG. 5, in the state where the permanent magnets 321 are lowered to be attached (or close to) the upper surface of the magnetic force generating unit 311, When the periodic shock pulse (first shock pulse) having a duty or voltage exceeding the reference value is supplied to the magnetic force generating unit 311, the permanent magnet 321 is completely spaced apart from the magnetic force generating unit 311. The shock vibration is generated by repeating the raised state and the fully lowered state that strikes the upper surface of the magnetic force generating unit 311.

That is, as shown in FIG. 6, the controller 200 receives the periodic shock pulse a2 having the duty exceeding the reference value or the periodic shock pulse a2 ′ having the voltage exceeding the reference value in the forward direction. When the upper portion of the magnetic force generating unit 311 becomes the S pole and the lower portion becomes the N pole, thus the permanent magnet 321 is the resilience of the magnetic force generating unit 311 and the elastic restoring force of the elastic providing unit 312 As a result, it is in a fully ascending state, which is completely spaced apart from the magnetic force generating unit 311.

In addition, as shown in FIG. 7, when a periodic shock pulse a3 having a duty exceeding a reference value or a periodic shock pulse a3 ′ having a voltage exceeding a reference value is supplied in the reverse direction, the magnetic force generating unit The upper part of the 311 becomes the N pole and the lower part becomes the S pole. Accordingly, the permanent magnet 321 is in a fully lowered state in which the upper surface of the magnetic force generating unit 311 is hit by the attraction force with the magnetic force generating unit 311. Becomes

As described above, when the permanent magnet 321 is in the fully lowered state, the elastic force is stored in the elastic providing unit 312 to provide the elastic restoring force when the next permanent magnet 321 is raised.

As described above, the contactor 322 is fixed to one side of the permanent magnet 321, the contactor 322 is raised or lowered according to the movement of the permanent magnet 321, the permanent magnet 321 is fully raised The impact is generated by hitting the tip of the contact sensing unit 100 and the contactor 322.

That is, as shown in FIG. 6, the contactor 322 is vertically fixed to the upper surface of the permanent magnet 321 and spaced apart from the upper portion of the elastic providing unit 312 to provide the contact sensing unit 100. Can be.

Therefore, when the permanent magnet 321 is in a fully elevated state, the end of the contactor 322 hits the contact sensing unit 100 to generate an impact.

In conclusion, as shown in FIGS. 6 and 7, when the permanent magnet 321 is fully raised, the end of the contactor 322 strikes the contact sensing unit 100 to generate an impact and permanently. When the magnet 321 is in the fully lowered state, the lower surface of the permanent magnet 321 strikes the upper surface of the magnetic force generating unit 311 to generate an impact, thereby generating shock vibration.

On the other hand, the sound limiter 313 is stacked on the upper surface of the magnetic force generating unit 311, the permanent magnet 321 is in a fully lowered state, the lower surface of the permanent magnet 321 hits the upper surface of the magnetic force generating unit 311 It is desirable to prevent noise in the background.

In addition, the periodic electrical energy is a signal in which periodic shock pulses having a voltage exceeding a reference value are alternately alternately in the forward and reverse directions, and of course, may be configured as electrical energy in which polarities are alternately intersected. As such, when the polarity is composed of alternating electrical energy, the vibration of the permanent magnet 321 may occur more greatly.

In addition, the inertial vibration of the permanent magnet 321 will be described. As shown in FIG. 8, in the state where the permanent magnet 321 is lowered to be attached to (or close to) the upper surface of the magnetic force generating unit 311, the magnetic force is lowered. When the periodic shock pulse (second shock pulse) having a duty and voltage below the reference value is supplied to the generating unit 311, the partial lift state and the magnetic force generating unit partially spaced from the magnetic force generating unit 311 ( The inertia vibration is generated by repeating the partially lowered state close to the upper surface of 311).

That is, as shown in FIG. 9, when the periodic shock pulse a4 having the duty and voltage lower than the reference value is supplied from the controller 200 in the forward direction, the upper portion of the magnetic force generating unit 311 is the S pole. The lower portion becomes the N pole, and thus the permanent magnet 321 is partially separated from the magnetic force generating unit 311 by the repulsive force with the magnetic force generating unit 311 and the elastic restoring force of the elastic providing unit 312. It goes up. In detail, the distance between the elastic providing unit 312 and the upper surface of the permanent magnet 321 is "d1", and the distance between the lower surface of the permanent magnet 321 and the soundproof limiter 313 is "d2".

At this time, since the magnetic force generating unit 311 is supplied with a periodic shock pulse having a duty and voltage of less than the reference value, the permanent magnet 321 and the generated repulsive force is smaller than the fully elevated state.

As described above, following the state of the partial rise, when the periodic shock pulse a5 having the duty and voltage lower than the reference value is supplied in the reverse direction, the magnetic force generating unit 311 The upper portion is the N pole and the lower portion is the S pole. Accordingly, the permanent magnet 321 is in a partially lowered state close to the upper surface of the magnetic force generating unit 311 by attraction with the magnetic force generating unit 311. In detail, the distance between the elastic providing unit 312 and the upper surface of the permanent magnet 321 is "d1" and larger than "d1", and the distance between the lower surface of the permanent magnet 321 and the limiter 313 is As "d2 '", it becomes smaller than "d2".

At this time, since the magnetic force generating unit 311 is supplied with a periodic shock pulse having a duty and voltage of less than the reference value, the permanent magnet 321 and the attraction force is smaller than the full rise state.

As described above, when the permanent magnet 321 is in the partially lowered state, the elastic force is stored in the elastic providing unit 312 to provide the elastic restoring force when the next permanent magnet 321 is raised.

In conclusion, as shown in FIGS. 9 and 10, when the permanent magnet 321 is partially lifted, the end of the contactor 322 does not strike the touch sensing unit 100, and the permanent magnet When 321 is in the partially lowered state, the lower surface of the permanent magnet 321 does not strike the upper surface of the magnetic force generating unit 311, and thus inertial vibration generated by the weight of the permanent magnet 321 This will occur.

On the other hand, the periodic electrical energy is a signal in which the periodic shock pulses having a voltage less than the reference value is alternately in the forward and reverse directions, of course, may be composed of electrical energy in which the polarity is alternated. As such, when the polarity is composed of alternating electrical energy, the vibration of the permanent magnet 321 may occur more significantly.

In the present embodiment, the actuator will be set as a bobbinless solenoid coil actuator, but the present invention is not limited thereto, but is not limited thereto, such as an AC motor, a DC motor, a servo motor, a rotary type / linear type vibration motor, a voice coil motor (VCM), The solenoid actuator, the piezo actuator, the ultrasonic actuator, the ceramic actuator, the electroactive polymer actuator, the shape memory alloy actuator (shape memory alloy) can be variously configured, or a combination thereof.

As described above and described with reference to a preferred embodiment for illustrating the technical idea of the present invention, the present invention is not limited to the configuration and operation as shown and described as described above, it is a deviation from the scope of the technical idea It will be understood by those skilled in the art that many modifications and variations can be made to the invention without departing from the scope of the invention.
