Meanwhile, in this embodiment, it has been explained that an anti-phase signal is generated by measuring and analyzing noise generated during treatment using a handpiece, etc., but the present invention is not necessarily limited to this.

That is, the storage unit 31 may further store information resulting from pre-measurement and analysis of noise generated during the operation of the plurality of handpieces provided in the treatment drive unit 14.

Therefore, when a handpiece among a plurality of handpieces starts operating, the control unit 30 searches for result information corresponding to the handpiece among the result information stored in the storage unit 31, and determines the noise level based on the searched result information. It can be controlled to output an anti-phase signal.

In the case of a general active noise removal device, time delays occur in the process of measuring and analyzing noise, making it difficult to respond to noise in real time, which may reduce noise removal efficiency.

Therefore, the present invention measures and analyzes the noise generated during operation of each handpiece provided in the treatment drive unit in advance, stores the resulting information in the storage unit, and generates an anti-phase signal corresponding to the noise generated at the same time as the corresponding handpiece operates. By printing, noise generated during the treatment process can be more effectively eliminated.

A concave groove may be formed on the front of the support 15 so that the patient's head can be comfortably seated.

The guide rails 16 may be installed on the support 15 in one or more pairs, for example, along the horizontal direction.

A pair of moving members 17 functions to fix the patient's head during the treatment process. To this end, the pair of moving members 17 can each move along the guide rail 16.

That is, the pair of moving members 17 are normally placed on both sides of the support 15 at a certain distance or more from each other, and when the patient's head is seated on the support 15, they are positioned to approach both ears of the patient. You can move.

Here, the angle or distance between the two ears may vary depending on the patient's age, gender, physique, etc.

Therefore, the pair of moving members 17 can be installed on the pair of guide rails 16 to enable angle adjustment.

In this way, by adjusting the distance between the pair of moving members 17 and the angle of each moving member 17, the opposing angle of the pair of speakers 23 is configured to be variable, so that the speaker ( 23) can be moved in close contact or proximity.

In addition, the headrest 13 may be provided with a driving unit (not shown) that generates a driving force to move the moving member 17 according to a control signal from the control unit 30.

Additionally, a detection sensor (not shown) may be installed in the headrest 13 to detect whether the patient's head is seated on the support 21.

The detection sensor can detect whether the patient's head is seated in various ways, such as a pressure sensor that detects the pressure applied to the support 15, a distance sensor, a proximity sensor, or an ultrasonic sensor that detects whether the head is seated. there is.

Therefore, the control unit 30 may generate a control signal to control the driving of the driving unit to move the pair of moving members 17 away from or closer to each other based on the detection signal output from the detection sensor.

The speakers 23 are each installed on a pair of moving members 17, and can be brought into close contact with or close to both ears of the patient by moving the moving members 17.

Therefore, the speaker 23 outputs an anti-phase signal to control noise generated during the treatment process and can output various contents such as music or sounds preferred by the patient.

And the microphone provided as the noise measuring unit 21 may be installed on any one of the pair of moving members 17 or on each of the pair of moving members 17.

As such, the present invention can remove noise generated during treatment and provide music or sounds preferred by the patient by installing speakers on the headrest to be movable toward both ears of the patient.

Meanwhile, the active noise control chair 10 according to a preferred embodiment of the present invention may further include a display unit 40 that displays an operating state and a communication unit 50 that communicates with an external electronic device 60.

The display unit 40 may be provided as a touch panel that provides both an input function for receiving operating commands from a user, that is, a doctor or nurse, and a display function for displaying an operating state.

Of course, the present invention may be modified to provide an input unit separate from the display unit 40.

The communication unit 50 can communicate with various types of electronic devices 60 having communication functions, such as a user's or patient's smartphone, a tablet PC, and a laptop or desktop computer provided at the relevant hospital, through wireless or wired communication.

For example, the communication unit 50 may communicate with the electronic device 60 through a wired network inside the hospital or through various wireless communication methods such as Bluetooth, Wi-Fi, and WiMAX.

Therefore, the communication unit 50 can receive various contents such as videos, music, and pictures from the corresponding electronic device 60.

That is, the control unit 30 transmits content such as videos, music, and pictures received from various electronic devices 60, such as computer terminals in the hospital or patient user terminals, through the communication unit 50 to the display unit 40 and the speaker 23. You can control the output through .

For example, if the patient is a child, the control unit 30 can control to select and output content such as videos, music, or pictures featuring characters that children like during treatment.

As such, the present invention can actively control noise generated during the treatment process by applying an active noise control device to the treatment chair in hospitals that use handpieces, etc. during the treatment process, such as dentistry or otolaryngology.

In addition, the present invention can relieve the patient's tension caused by noise generated during treatment, reduce pain, and eliminate fear of noise by providing a variety of content tailored to the patient's taste during the treatment process.

Figure 4 is a flowchart explaining step by step the control method of an active noise control chair according to a preferred embodiment of the present invention.

When the power switch (not shown) is turned on in step S10 of FIG. 4, the power supply unit (not shown) supplies power to each device provided in the active noise control device 100.

Then, the control unit 30 executes the driving program stored in the storage unit 31 to initialize each device and prepares to perform a treatment operation.

At this time, when the patient sits on the chair body 11, the angle of the backrest and headrest may be adjusted through a tilting operation so as to comfortably support the patient's back and head.

Therefore, when the backrest 12 and the headrest 13 are contacted, the detection sensor installed on the headrest 13 outputs a detection signal according to the contact with the patient's head. Then, the control unit 30 can control the pair of moving members 17 installed on both sides of the headrest 13 to move closer to both ears of the patient. Therefore, the patient's head can be fixed by a pair of moving members (17).

In step S12, when an operation command from a user, that is, a doctor or nurse, is input through the display unit 40 or an input unit, the control unit 30 controls the treatment drive unit 14 to operate according to the input operation command.

At this time, the control unit 30 may receive various contents from the electronic device 60 through the communication unit 50 and control the received contents to be output through the display unit 40 and the speaker 23.

When treatment begins in step S14, the noise measurement unit 21 provided in the noise removal unit 20 measures noise generated during the treatment process.

In step S16, the control unit 30 compares the measured noise level with a preset decibel value to check whether noise exceeding the set decibel value is generated.

If the noise measured as a result of the inspection in step S16 is less than the set decibel value, the control unit 30 proceeds to step S14 and repeats the subsequent process.

On the other hand, if the noise measured as a result of the inspection in step S16 is more than the set decibel value, the control unit 30 determines that noise has occurred. Then, the analysis unit 22 provided in the noise removal unit 20 analyzes the measured noise, and the control unit 30 controls to output an anti-phase signal of the analyzed noise through the speaker 23 (S18).

Of course, the present invention measures and analyzes the noise generated during operation of each handpiece provided in the treatment drive unit in advance, stores the information in the storage unit, and generates an anti-phase signal corresponding to the noise generated at the same time as the handpiece operates. By printing, noise generated during the treatment process can be more effectively eliminated.

In step S20, the control unit 30 checks whether the treatment process is completed and repeats steps S14 to S20 until the treatment process is completed.

Meanwhile, when the treatment process is completed as a result of the examination in step S20, the control unit 30 stops operating each device and ends.

Through the process described above, the present invention can actively control noise generated during the treatment process by applying an active noise control device to the treatment chair in hospitals that use handpieces, etc. during the treatment process, such as dentistry or otolaryngology.

In addition, the present invention can relieve the patient's tension caused by noise generated during treatment, reduce pain, and eliminate fear of noise by providing a variety of content tailored to the patient's taste during the treatment process.

Accordingly, the present invention can facilitate patient treatment and improve satisfaction by allowing patients to receive treatment comfortably.

Although the invention made by the present inventor has been described in detail according to the above-mentioned embodiments, the present invention is not limited to the above-described embodiments and, of course, can be changed in various ways without departing from the gist of the invention.
