FIG. 1 is a view showing the inside of a smart table 100 according to an embodiment of the present invention, and FIG. 2 is an illustration showing the outside of a smart table 100 according to an embodiment of the present invention. The smart table 100 according to an exemplary embodiment of the present invention is a table having a built-in speaker. The smart table 100 may be a circular or square plate and a leg supporting the same.

1 and 2, the smart table 100 includes at least one speaker 102, at least one motion detection sensor 104, 106, a control module 108, a touch sensor 110, a lighting module 112, a power supply unit 114, an extension socket 116, and a support pedestal 118.

The speaker 102 is a device for outputting sounds, and may be provided in the smart table 100 or more. The speaker 102 may include, for example, a first speaker 102a and a second speaker 102b, wherein the first speaker 102a is provided on the left side of the smart table 100 and the second speaker 102b May be provided on the right side of the smart table 100. However, this is merely an example, and the number and position of the speaker 102 are not limited thereto. 1 and 2, the speaker 102 is shown as being embedded in the smart table 100, but the present invention is not limited thereto. The speaker 102 may be mounted on the outer surface of the smart table 100.

The speaker 102 may be connected, for example, by a wired or wireless connection to a user terminal (not shown, e.g., a smart phone, MP3, etc.), an audio device (not shown, e.g., The sound output from the selected sound or audio device can be output. To this end, the speaker 102 may include a connector (not shown) for wired communication, a Bluetooth module (not shown) for wireless communication, and a Wi-Fi module (not shown).

Also, as will be described later, the speaker 102 can be easily controlled according to the motion of the user rather than being controlled by a user pressing a separate button. Accordingly, the operation of the user (for example, , Conference, etc.) efficiency and concentration can be improved.

The motion detection sensors 104 and 106 are sensors for sensing the operation of the user and may be disposed at least one point of the smart table 100. [ The motion detection sensors 104 and 106 may include a plurality of infrared sensors 104 and a plurality of ultrasonic sensors 106, for example. The infrared sensor 104 may include a first infrared sensor 104a and a second infrared sensor 104b and the first infrared sensor 104a and the second infrared sensor 104b may be connected to the smart table 100 On the left side and the right side, respectively. The ultrasonic sensor 106 may include a first ultrasonic sensor 106a, a second ultrasonic sensor 106b and a third ultrasonic sensor 106c. The first ultrasonic sensor 106a, the second ultrasonic sensor 106a, The second ultrasonic sensor 106b and the third ultrasonic sensor 106c may be disposed on the outer surface of the smart table 100 at a predetermined interval. However, this is merely an example, and the number and position of the infrared sensor 104 and the ultrasonic sensor 106 are not limited thereto.

The infrared sensor 104 and the ultrasonic sensor 106 can sense the operation of the user and the control module 108 to be described later can detect the operation of the user by the operation of the user detected by the infrared sensor 104 and the ultrasonic sensor 106. [ The sound volume and the sound band of the sound output from the sound output unit 102 can be controlled. Here, the operation of the user may include, for example, an operation in which the user raises the hand upward, an operation in which the user moves the hand downward, an operation in which the user moves the hand from the left to the right, Or an operation of moving in a direction. However, this is merely an example, and the operation of the user is not limited thereto.

Each of the infrared sensors 104a and 104b can sense the operation of the user by sensing the presence or absence of a target object within a set distance (e.g., a user's hand), and each of the infrared sensors 106a, 106b, And by detecting how far the object is from the ultrasonic sensors 106a, 106b, and 106c. The infrared sensors 104a and 104b may be used for sound volume control, mute control, selection of light emitted from the illumination module 112, and the like. The ultrasonic sensors 106a, 106b, It is possible to use the relative distance to each of the ultrasonic sensors 106a, 106b, and 106c and the object to control the sound band of the sound (i.e., the equalizer function).

Each of the ultrasonic sensors 106a, 106b and 106c has a trigger pin (not shown) for preventing overlapping (or interference) between signals output from the ultrasonic sensors 106a, 106b and 106c. The operation can be sequentially detected. In general, the ultrasonic sensors 106a, 106b, and 106c transmit ultrasonic waves to a target object, and receive ultrasonic waves reflected from the target object and return to the target object. Then, the ultrasonic sensors 106a, 106b, 106c and the object can be calculated. However, in the present embodiments, since the plurality of ultrasonic sensors 106a, 106b, and 106c are used, signals (i.e., ultrasonic waves) output from the respective ultrasonic sensors 106a, 106b, and 106c overlap each other The ultrasonic sensors 106a, 106b, and 106c sequentially transmit and receive signals. To this end, each of the ultrasonic sensors 106a, 106b, and 106c may sequentially perform signal transmission and reception alternately after waiting for a predetermined time by communicating with each other. In this case, it is possible to prevent overlapping and interference between signals output from the ultrasonic sensors 106a, 106b, and 106c, and more accurately detect the operation of the user. Also, the sequential signal transmitting / receiving process can be repeated 10 times per second, for example, so that the accuracy of motion detection can be further improved.

The control module 108 controls at least one of the volume and the band of the sound output from the speaker 102 according to the operation of the user detected by the motion detection sensors 104 and 106. As described above, the motion detection sensors 104 and 106 may include a plurality of infrared sensors 104 and a plurality of ultrasonic sensors 106. The control module 108 controls the volume of the sound output from the speaker 102 according to the operation of the user sensed by the plurality of infrared sensors 104. In accordance with the operation of the user sensed by the plurality of ultrasonic sensors 106 It is possible to control the band of the sound output from the speaker 102. [ The control module 108 may include a microcontroller unit (MCU) or an audio hacker kit for controlling the sound, and the MCU or the audio hacker kit may be configured to amplify, And the like. The control module 108 is connected to the speaker 102, the motion sensors 104 and 106, the touch sensor 110, the illumination module 112 and the like to transmit and receive signals. (For example, compressing 24-bit sound quality to 8 bits), recording, repeated loop playback, selecting a song / turning a song / returning a song, voice guidance for each language, lighting module And the light emission control of the light source 112 can be performed.

The control module 108 receives an input value relating to the operation detected by the infrared sensor 104 or the ultrasonic sensor 106 from the infrared sensor 104 or the ultrasonic sensor 106 and outputs the input value to the input value Converted to a corresponding code value, and then transmitted to the speaker 102. [ The speaker 102 can receive the code value from the control module 108, so that the volume, the frequency band, etc. of the sound output from the speaker 102 can be controlled.

In one example, when the operation detected by the infrared sensor 104 is " an operation in which the user raises his / her hand upward ", the control module 108 sets an input value related to " (For example, 010100) corresponding to the input value, and may transmit the converted value to the speaker 102. The speaker 102 may receive the input value from the infrared sensor 104, The speaker 102 may increase the volume of the sound output according to the code value received from the control module 108. [

As another example, when the operation sensed by the ultrasonic sensor 106 is " an operation in which the user moves his or her hand from left to right ", the control module 108 determines that " the operation in which the user moves his / her hand from left to right Quot; from the ultrasonic sensor 106 and convert the input value to a code value (for example, 100110) corresponding to the input value, and then transmit the code value to the speaker 102. [ The speaker 102 can convert the sound band of the sound output according to the code value received from the control module 108 into a preset low frequency band.

At this time, the control module 108 may compare any of the input values detected by the ultrasonic sensors 106a, 106b, and 106c to select any one of the plurality of frequency bands. As an example, when it is assumed that the first ultrasonic sensor 106a corresponds to the low sound, the second ultrasonic sensor 106b corresponds to the middle sound, and the third ultrasonic sensor 106c corresponds to the high sound, The second ultrasonic sensor 106b and the third ultrasonic sensor 106c are operated by the user's hand when the input value sensed by the first ultrasonic sensor 106a is smaller than a set valid value (for example, an input value measured when the object is sensed within 30 cm) It can be determined that the same object has been detected and the operation of the user can be detected. When the input value detected by the first ultrasonic sensor 106a is smaller than the set effective value, the second ultrasonic sensor 106b waits for input of an input value smaller than the valid value, and the input sensed by the second ultrasonic sensor 106b The third ultrasonic sensor 106c may wait for input of an input value smaller than the valid value. When the input value sensed by the third ultrasonic sensor 106c is smaller than the set effective value, the control module 108 may perform a frequency band (filter) selection process. Specifically, the control module 108 compares the input values sensed by the first ultrasonic sensor 106a, the second ultrasonic sensor 106b, and the third ultrasonic sensor 106c with each other, and calculates a relative difference Quot; high " or " low ", it is possible to recognize the following operation of the user and select the corresponding band.

User behavior First ultrasound
The sensor
Input value Second ultrasound
The sensor
Input value Third ultrasound
The sensor
Input value A sound band
(filter) → height lowness lowness ① ← lowness height lowness ② ↗ lowness lowness height ③ ↘ height height lowness ④ ↖ height lowness height ⑤ ↙ lowness height height ⑥

For example, when the input value sensed by the first ultrasonic sensor 106a is low and the input sensed by the second ultrasonic sensor 106b and the third ultrasonic sensor 106c is high, the control module 108 controls the sound The frequency band of the sound can be controlled to the sixth band of Table 1 by selecting a filter that increases the middle and high frequencies and reduces the bass. Also, as described later, the control module 108 may control the lighting module 112 to switch the color of the light emitted from the lighting module 112 to a color corresponding to the selected band. In the above example, the lighting module 112 may emit light of "green (middle tone) + blue (treble) = cyan". The number of operations and the frequency band of the user is only an example, and the number of the operation and the frequency band of the user can be further increased by increasing the number of the ultrasonic sensors 106.

Conventionally, any one of three predetermined filters (High Pass Filter, Band Pass Filter, and Low Pass Filter) has to be manually selected, so that it is difficult for a user to output a sound in a desired atmosphere. For example, the High Pass Filter sounds high, but low-frequency sounds such as drums and bass can hardly be heard. In the case of the Low Pass Filter, only the drums and bass sounds are emphasized. There was a problem that can not be heard clearly. However, according to the embodiments of the present invention, instead of selecting only the three bands of the predetermined bass, midtone, and treble, the input values sensed by the respective ultrasonic sensors 106 are compared with each other, In this case, it is possible to select various ranges according to the needs and preferences of the user.

The touch sensor 110 is a sensor used to switch the motion detection sensors 104 and 106 into the locked state or the unlocked state and is provided in the smart table 100 to sense the user's touch. For example, the control module 108 may detect the touch of the user at the touch sensor 110, and thereby detect the touch of the user in the locked state or the hold state (i.e., (I.e., a state in which the operation recognition of the operation unit 10 can not be recognized). In addition, the control module 108 controls the operation of the operation sensors 104 and 106 in the unlocked state (that is, the operation detection sensors 104 and 106) (I.e., a state in which it is possible).

In addition, the touch sensor 110 may include an LED (not shown), and may emit light of different colors through the LED depending on whether the motion detection sensors 104 and 106 are in a locked state or an unlocked state can do. For example, when the user touches the touch sensor 110 and the motion detection sensors 104 and 106 are switched to the locked state, the touch sensor 110 can emit red light through the LED. In addition, when the user touches the touch sensor 110 again and the motion detection sensors 104 and 106 are switched to the unlocked state, the touch sensor 110 emits green light (or light Blocking).

The lighting module 112 emits light of different colors or changes the brightness of the light depending on the sound level or the sound band of the sound output from the speaker 102. As shown in FIG. 2, the illumination module 112 may be cylindrical and may be disposed on the outer surface of the smart table 100. However, this is merely an example, and the shape and arrangement position of the lighting module 112 are not limited thereto.

As an example, the lighting module 112 may emit light of different colors or change the brightness of the light according to the volume of the sound output from the speaker 102. For example, when the volume of the sound output from the speaker 102 increases under the control of the control module 108, the control module 108 controls the lighting module 112 such that the brightness of the light emitted from the lighting module 112 increases, (112). At this time, the lighting module 112 may receive a code value regarding the volume of the sound from the control module 108, and may change the color or brightness of the light according to the code value.

As another example, the lighting module 112 may emit light of different colors or change the brightness of the light according to the band of the sound output from the speaker 102. For example, when the frequency band of the sound output from the speaker 102 under control of the control module 108 is converted to the sixth band of Table 1, the control module 108 emits light from the illumination module 112 The lighting module 112 can be controlled so that the color of light is converted to cyan. At this time, the lighting module 112 can receive the code value of the sound band of the sound from the control module 108, and can change the color or brightness of the light according to the code value.

As described above, according to the embodiments of the present invention, the color or brightness of the light emitted from the lighting module 112 is changed according to the sound volume or the sound band of the sound output from the speaker 102, You can intuitively identify information about the sound (volume, range, etc.).

The power supply unit 114 is a device that provides power to the speaker 102, the motion detection sensors 104 and 106, the control module 108, the touch sensor 110, and the illumination module 112. The speaker 102, the motion detection sensors 104 and 106, the control module 108, the touch sensor 110, the lighting module 112 and the like can be operated by receiving power from the power supply 114. The power supply unit 114 may be connected to an outlet or an extension socket 116.

The extension socket 116 is a component for power supply and can be connected to the power supply 114. The extension receptacle 116 performs a function similar to that of the multi-charger, and may include a plurality of USB terminals (not shown). Also, the extension socket 116 may be connected to an outlet provided inside the smart outlet 100.

The support pedestal 118 is a pedestal for supporting the smart table 100 and may be disposed on the inner surface of the smart table 100 at a predetermined interval. The support pedestal 118 may have a rectangular plate shape, but the shape of the support pedestal 118 is not limited thereto.

3 is a flowchart illustrating a process of controlling the volume of sound output from the smart table 100 according to an exemplary embodiment of the present invention. The methods described below can be performed, for example, by the smart table 100 described above. Further, although the above-described method is described by dividing into a plurality of steps in the flowchart shown in the figure, at least some of the steps may be carried out in sequence, combined with other steps, performed together, omitted, divided into detailed steps, May be performed with one or more additional steps being added.

In step S302, the first infrared sensor 104a senses the operation of the user.

In step S304, the second infrared sensor 104b senses the operation of the user.

In step S306, the first infrared sensor 104a and the second infrared sensor 104b communicate with each other to determine the time required between steps S302 and S304 (i.e., the time when the first infrared sensor 104a senses the operation, (I.e., the difference between the time at which the infrared sensor 104b senses the operation) is within a set value (for example, 1.5 seconds).

If it is determined in step S306 that the required time between step S302 and step S304 is within the set value, the first infrared sensor 104a and the second infrared sensor 104b are operated by the corresponding sensor And transmits an input value relating to the detected operation to the control module 108. [

If it is determined in step S306 that the required time between step S302 and step S304 exceeds a predetermined value, the first infrared sensor 104a and the second infrared sensor 104b may detect an operation Is not transmitted to the control module 108, and steps S302 and S304 are repeatedly performed. If the required time between steps S302 and S304 exceeds the set value, the operation detected by the first infrared sensor 104a and the second infrared sensor 104b is not a user's operation (for example, a manual operation) It may be an obstacle. That is, according to the embodiments of the present invention, it is assumed that the operation of the user is performed within a set time (for example, 1.5 seconds), and only when the steps S302 and S304 are performed within the set time, Can operate.

In step S310, the control module 108 controls the volume of the sound output from the speaker 102 using the input value. Specifically, the control module 108 may convert the input value into a code value corresponding to the input value, and then transmit the code value to the speaker 102 to control the volume of the sound.

In step S406, the first infrared sensor 104a senses the operation of the user.

In step S408, the second infrared sensor 104b senses the operation of the user.

The first infrared sensor 104a and the second infrared sensor 104b communicate with each other at step S410 so that the time required between steps S406 and S408 (i.e., the time when the first infrared sensor 104a senses the operation, (I.e., the difference between the time at which the infrared sensor 104b senses the operation) is within a set value (for example, 1.5 seconds).

If it is determined in step S410 that the required time between step S406 and step S408 is within the set value, the first infrared sensor 104a and the second infrared sensor 104b are operated by the corresponding sensor And transmits an input value relating to the detected operation to the control module 108. [

If it is determined in step S410 that the required time between step S406 and step S408 exceeds a predetermined value, the first infrared sensor 104a and the second infrared sensor 104b may detect an operation The control module 108 does not transmit the input value to the control module 108, and steps S404 to S408 are repeatedly performed.

In step S414, the control module 108 controls the volume of the sound output from the speaker 102 using the input value. Specifically, the control module 108 may convert the input value into a code value corresponding to the input value, and then transmit the code value to the speaker 102 to control the volume of the sound.

In step S416, the control module 108 controls the lighting module 112 according to the input value and the corresponding volume. For example, when the volume of the sound output from the speaker 102 increases under the control of the control module 108, the control module 108 controls the lighting module 112 such that the brightness of the light emitted from the lighting module 112 increases, (112).

In step S418, the plurality of infrared sensors 104a and 104b simultaneously detect the user's operation. The simultaneous detection of the user's operation by the plurality of infrared sensors 104a and 104b may be performed when the user covers the plurality of infrared sensors 104a and 104b by hand, for example.

In step S420, the illumination module 112 simultaneously emits light of a predetermined color as the plurality of infrared sensors 104a and 104b sense the user's operation. The stored color may be the same as the color in step S404, but is not limited thereto, and the lighting module 112 may emit light of a different color from that in step S404.

FIG. 5 is a flowchart illustrating a process of controlling whether a sound output from the smart table 100 is muted according to an embodiment of the present invention. Referring to FIG.

In step S502, the plurality of infrared sensors 104a and 104b simultaneously detect the user's operation. The simultaneous detection of the user's operation by the plurality of infrared sensors 104a and 104b may be performed when the user covers the plurality of infrared sensors 104a and 104b by hand, for example.

In step S504, the first infrared sensor 104a and the second infrared sensor 104b transmit the input value related to the operation detected by the corresponding sensor to the control module 108. [

In step S506, the control module 108 turns off the speaker 102 so that the volume of the sound output from the speaker 102 becomes 0 according to the input value, (112) is turned off.

In step S508, the plurality of infrared sensors 104a and 104b simultaneously detect the user's operation. The simultaneous detection of the user's operation by the plurality of infrared sensors 104a and 104b may be performed when the user covers the plurality of infrared sensors 104a and 104b by hand, for example.

In step S510, the first infrared sensor 104a and the second infrared sensor 104b transmit the input value related to the operation detected by the corresponding sensor to the control module 108. [

In step S512, the control module 108 turns on the speaker 102 to restore the volume of the sound output from the speaker 102 according to the input value, and controls the lighting module 112 to restore the light output from the lighting module 112 112).

In step S608, the first ultrasonic sensor 106a, the second ultrasonic sensor 106b, and the third ultrasonic sensor 106c communicate with each other so that the time required in steps S602 through S606 is set to a predetermined value (for example, 1.5 seconds) Or not.

If it is determined in step S608 that the required time in steps S602 to S606 is within the set value, the process proceeds to step S610. In step S610, the first ultrasonic sensor 106a, the second ultrasonic sensor 106b, The controller 106c transmits an input value related to the operation detected by the sensor to the control module 108. [

If it is determined in step S608 that the required time in steps S602 to S606 exceeds the set value, the first ultrasonic sensor 106a, the second ultrasonic sensor 106b, The control module 108 does not transmit the input value related to the operation detected by the sensor to the control module 108, and steps S602 to S606 are repeatedly performed. If the time required in steps S602 to S606 exceeds a predetermined value, the operation detected by the first ultrasonic sensor 106a, the second ultrasonic sensor 106b, and the third ultrasonic sensor 106c is the operation of the user For example, it may be a temporary obstacle rather than a hand movement. That is, according to the embodiments of the present invention, it is assumed that the operation of the user is performed within a set time (for example, 1.5 seconds), and only when the steps S602 to S606 are performed within the set time, Can operate.

In step S612, the control module 108 controls the band of the sound output from the speaker 102 using the input value. As described above, the control module 108 may convert the input value into a code value of a band corresponding to the input value, and then transmit the code value to the speaker 102 to control the band of the sound. At this time, the control module 108 compares the input values sensed by the first ultrasonic sensor 106a, the second ultrasonic sensor 106b, and the third ultrasonic sensor 106c with each other, and calculates a relative difference between the input values It is possible to recognize the operation of the user and select the corresponding range band by classifying each input value as " high " or " low ".

In step S614, the control module 108 controls the lighting module 112 according to the input value and the corresponding frequency band. For example, when the frequency band of the sound output from the speaker 102 under control of the control module 108 is converted to the sixth band of Table 1, the control module 108 emits light from the illumination module 112 You can turn the color of light into cyan.
