Hereinafter, the present disclosure will be described in more detail with reference to the drawings.

1A and 1B are diagrams for describing an air conditioner according to an exemplary embodiment of the present disclosure.

Referring to FIG. 1A, the air conditioner 100 includes a fan 11, a duct 12, a microphone 110, a processor 120, and a speaker 130.

The air conditioner 100 may perform an operation for conditioning indoor air. Specifically, the air conditioner 100 purifies contaminants contained in indoor air, cooling to lower the temperature of indoor air, heating to increase the temperature of indoor air, blowing to form an airflow in the room, and dehumidification to lower indoor humidity. At least one of the air cleaning functions may be performed.

The air conditioner 100 may include a fan 11 and may perform an operation for conditioning indoor air using the fan 11. Specifically, as power is applied from the air conditioner 100 to the fan 11, the fan 11 may start to rotate. The fan 11 is configured to cause air to flow, and may rotate at a constant number of rotations or cycles according to a preset operation mode of the air conditioner 100. Here, the operation mode may mean an operation state including a wind speed level of the air conditioner 100, a speed of the air conditioner, and the number of revolutions per minute of the fan 11 when the air conditioner 100 is operated.

The fan 11 rotates when the air conditioner 100 is operated, and may be a noise source of flow noise generated inside the air conditioner 100 according to the rotation of the fan 11. Since the fan 11 can operate at a constant number of rotations or at a constant cycle, it can generate a regular flow noise. Further, the noise generated from the fan 11 may be radiated to the inlet or outlet of the air conditioner 100 along the duct 12. Alternatively, noise generated from the fan 11 may pass through the main body of the air conditioner 100 and radiate to the outside of the air conditioner 100.

The air conditioner 100 may include a microphone 110. The microphone 110 is disposed inside the air conditioner 100 and may detect noise generated inside the air conditioner 100. The microphone 110 may be disposed in a direction in which noise generated inside the air conditioner 100 is discharged through the duct 12. The microphone 110 may be implemented in a form in which a wind prevention structure is applied to measure noise in a strong flow inside the air conditioner 100. In particular, the microphone 110 may be disposed at a location where air flow is relatively small, and may be disposed on an inner wall surface of the duct 12 of the air conditioner 100 or an airfoil structure.

In addition, the air conditioner 100 may include a plurality of microphones 110, and the plurality of microphones 110 may be disposed to be spaced apart between the fan 11 and the inlet or outlet. When a plurality of microphones 110 are included, since noise caused by wind detected by the microphone 110 can be distinguished, a reduction in noise can be increased.

The air conditioner 100 may include a processor 120. The processor 120 may generate noise information from the air conditioner 100 based on a signal output from the microphone 110. In addition, the processor 120 may generate an acoustic signal for canceling noise sensed at the spaced apart position based on position information and noise information about a position spaced apart from the air conditioner 100. In addition, the processor 120 may provide the generated sound signal to the speaker 130. A description related to the generation of the sound signal will be described later in FIG. 1C.

When receiving the location information for the spaced apart location, the processor 120 calculates a sound transfer function between the spaced location and the air conditioner based on the received location information, and based on the calculated sound transfer function and noise information. It can generate an acoustic signal.

The air conditioner 100 may include a speaker 130. The speaker 130 may receive an acoustic signal generated from the processor 120 and output a signal having a phase opposite to that of noise detected at a spaced apart position based on the acoustic signal. The speaker 130 may be disposed inside the air conditioner 100, and specifically, the speaker 130 may be disposed along the inner wall surface or the duct 12 of the air conditioner 100, and the airfoil structure Can be placed on As shown in FIG. 1A, the speaker 130 may be disposed farther away from the fan 11 than the microphone 110. In addition, the air conditioner 100 may include a plurality of speakers 130, and noise reduction performance may increase as the number of speakers 130 and microphone 110 increases. Meanwhile, the speaker 130 may be in the form of an exciter that has a specific structure and generates sound.

Referring to FIG. 1C, a process of generating an acoustic signal by applying a weight filter to noise information is illustrated. The sound signal is generated by the processor 120 and may be a signal that controls the speaker 130 in order to cancel noise sensed at a spaced apart position.

The processor 120 may generate noise information from the air conditioner 100 based on a signal output from the microphone 110 and may generate an acoustic signal by applying a weight filter to the generated noise information. A method of calculating the weight filter will be described in detail in FIG. 1D.

Specifically, the processor 120 may generate an acoustic signal by applying a weight filter and a control path filter to noise information. Referring to FIG. 1A, due to the structure of the air conditioner 100, sound radiated from the speaker 130 into the duct 12 may be received by the microphone 110. When the microphone 110 recognizes the sound received from the speaker 130 as noise, the processor 120 generates an erroneous sound signal, thereby reducing the degree of noise reduction. Accordingly, a sound transfer function from the speaker 130 to the microphone 110 is calculated, and the sound received by the microphone 110 is filtered to generate a more accurate sound signal.

The air conditioner 100 may more accurately calculate the weight filter when the surrounding environment is similar to the experimental environment. Accordingly, the air conditioner 100 may calculate a weight filter or perform an update after determining whether the noise level satisfies a preset criterion.

The air conditioner 100 may generate a trigger signal by controlling the speaker 130 (S100). The trigger signal is recorded using the microphone 110 included in the air conditioner 100 and the microphone included in the external device, and the air conditioner 100 may analyze the spectrum of the recorded trigger signal (S110). ). The air conditioning apparatus 100 may determine whether the noise level satisfies a preset criterion by analyzing the spectrum of the recorded trigger signal (S120).

When the noise level satisfies a preset criterion, the air conditioning apparatus 100 may calculate a weight filter or perform an update. The air conditioner 100 may generate a trigger signal by controlling the speaker 130 (S130). The trigger signal generated by the speaker 130 may be recorded using a microphone 110 included in the air conditioner 100 and a microphone (not shown) included in an external device (S140). Then, the sound transfer function from each of the microphone 110 included in the air conditioner 100 and a microphone (not shown) included in the external device to the air conditioner 100 is calculated, and based on the calculated sound transfer function Thus, the control path filter may be calculated and stored (S150). In addition, the control code filter may be calculated and stored every predetermined period and updated (S160).

Without applying an acoustic signal for noise canceling to the speaker 130 of the air conditioner 100, the weight filter may be calculated and stored by accurately grasping noise information from the air conditioner 100. First, the air conditioner 100 may start to operate (S170). That is, the fan 11 of the air conditioner 100 may be driven and an operation for conditioning indoor air may be performed. In a situation in which flow noise is generated by the operation of the air conditioner 100, a trigger signal is generated by controlling the speaker of the air conditioner 100 in order to calculate a weight filter (S180). Trigger signals may be recorded from the microphone 110 included in the air conditioner 100 and a microphone (not shown) included in an external device. A sound transfer function may be calculated from each of the microphone 110 included in the air conditioner 100 and a microphone (not shown) included in an external device, and a weight filter may be calculated and stored based on the calculated sound transfer function ( S190). The air conditioner 100 may update an existing weight filter with the calculated weight filter (S200).

As the fan 21 operates, air flow may occur from the intake port at the lower end of the air conditioner 100 to the discharge port at the upper end. Together with the generated air flow, the flow noise generated from the fan 21 may be radiated to the inlet or outlet. Flow noise may be detected by the auxiliary microphone 150 disposed at the inlet or outlet of the air conditioner 100.

The auxiliary microphone 150 may be disposed adjacent to the suction port or the discharge port, and may be mounted on the inner wall surface 23 of the duct. In addition, the air conditioner 100 may include a plurality of auxiliary microphones 150. The processor 120 generates error information based on a signal output from the auxiliary microphone 150 and a signal output from the microphone 110, and position information about a position spaced apart from the air conditioner 100, the generated error An acoustic signal may be generated based on the information and noise information from the air conditioner output from the microphone 110. When generating an acoustic signal by further considering the output signal sensed by the auxiliary microphone 150, the degree of noise reduction at the inlet or outlet where the auxiliary microphone 150 is disposed is determined based on the error information, and an acoustic signal is generated. Therefore, it is possible to increase the degree of noise reduction.

The communication interface 140 may communicate with an external device. The communication interface 140 may receive at least one of a location of an external device capable of communicating with the air conditioning device 100 or a location of a user detected by the air conditioning device.

In one embodiment, the infrared module (not shown) is user input information from the remote control of the air conditioner 100 Infrared light can be received.

In particular, the memory 160 may be implemented as a nonvolatile memory, a volatile memory, a flash memory, a hard disk drive (HDD), a solid state drive (SSD), or the like.

When the air conditioner 100 receives location information about a location spaced apart from the air conditioner 100, the sound transfer function between the spaced location and the air conditioner 100 is calculated based on the received location information. , A sound signal may be generated based on the calculated sound transfer function and noise information. Here, the sound transfer function may mean a mathematical relationship between an output and an input in a frequency domain.

The air conditioning apparatus 100 may receive location information on at least one of a location of an external device or a location of a user from an external device capable of communicating.

It can generate an acoustic signal. The closer to the air conditioner 100, the greater the noise generated from the air conditioner 100 can be detected. Therefore, the air conditioner 100 is located at the closest position to the air conditioner 100 among a plurality of spaced positions. An acoustic signal can be generated so that the size of the corresponding noise is the smallest. In FIG. 3, when the position of the desk 32 among the positions of the user 31, the desk 32, and the bed 33 is the closest, the air conditioner 100 is An acoustic signal is generated based on the sound transfer function up to (32), and noise generated at the position of the desk 32 can be reduced.
