The mask apparatus 2 may transmit and receive sound information to and from a terminal or server through the wireless communication portion 520. Sound information received through the wireless communication portion 520 may be stored in the information storage portion 510. The controller 500 may output sound through the second speaker 580 based on the sound information stored in the storage device. For example, the controller 500 may output music sound to the second speaker 580 through the audio signal processor 550. The audio signal processor 550 may transform the frequency of the sound output through the second speaker 580 into a frequency that can be resonated in the second resonant spaces 631a and 632a and output the converted sound. A sound having a higher frequency than the frequency of the sound output through the second speaker 580 may be output through the second resonance opening 620.
The mask apparatus 2 may enable voice communication through the wireless communication portion 520, the microphone 560, and the second speaker 580. The controller 500 may transmit and receive sound information to and from the terminal through the wireless communication portion 520. A user's sound may be received through the microphone 560 and the received sound may be transmitted to the terminal through the wireless communication portion 520. Sound information received from the terminal to the wireless communication portion 520 may be output through the second speaker 580.
In other words, the user can enjoy music in a state of wearing the mask apparatus 2. In addition, the user may make a phone call in a state of wearing the mask apparatus 2. In addition, the user may be able to communicate with others in a state of wearing the mask apparatus 2. In addition, the mask apparatus 2 may modify the frequency of the output sound so that the sound is output with a higher frequency. In other words, since the output of the speakers 570 and 580 can be adjusted while outputting a loud sound using resonance, the power efficiency of the mask apparatus 2 can be improved.
Meanwhile, the mask apparatus 2 according to the present disclosure may include a first boundary region B1 formed in the sealing portion 40 forming a breathing space, and a second boundary region B2 located outside the breathing space and formed in a flange of the mask body 10.
A breathing space is located in the first boundary region B1, and an enclosed space distinguished from the external space may be formed. A space formed by the first boundary region B1 may be referred to as a first boundary space B1s. The user's nose and mouth are located in the first boundary space B1s, and the microphone 560 may be located inside the first boundary space B1s. The first boundary space B1s is located in front of the user's nose and mouth, and components for supplying air to the breathing space may be located.
The second boundary area B2 is located outside the sealing portion 40 and may form a separate space distinguished from the first boundary area B1. A space formed by the second boundary area B2 may be referred to as a second boundary space B2s. The second boundary space B2s may be located between the first boundary area B1 and the second boundary area B2. The second boundary space B2s may be located in front of the user's cheekbones and both cheeks. Speakers 570 and 580 may be located in the second boundary space B2s. Since the speakers 570 and 580 are installed in the second boundary space B2s, weight distribution on both sides of the mask apparatus 2 can be uniformly adjusted. By forming a resonance space in the second boundary space B2s, the structure of the mask apparatus 2 can be optimally disposed. In this embodiment, a plurality of second boundary space B2s may be provided on both sides of the first boundary space B1s.

Detecting the operating mode may be understood as determining an operating mode based on the sensing information detected by the sensor portion 530 of the mask apparatus 2 by the controller 500 of the mask apparatus 2, the sound information processed by the audio signal processor 550, or the like (S10). The sensing information may include user breathing information, operation signal information of a fan module, and the like.
When the operation sound of the fan module is input to the microphone 560 of the audio signal processor 550 and the operation of the fan module of the mask apparatus 2 is detected by the sensor portion 530, the breathing mode (S100) can work (S110). It may be determined that the breathing mode (S100) is a state where no sound is input from the user and the user concentrates on breathing.
Alternatively, the user may directly control the operation of the mask apparatus 2 to select the breathing mode (S100). In addition, the user may select an operation mode by calling a breathing mode.
Since the user is concentrating on breathing in the breathing mode (S100), the sound generated by the fan module of the mask apparatus 2 may be transmitted as a loud noise to the user's ears.
In the breathing mode (S100), the controller 500 may output antiphase sound information corresponding to the sound of the fan module from the second speaker 580 based on the sound of the fan module input to the microphone 560 (S120).
Since the second speaker 580 outputs antiphase sound information corresponding to the sound of the fan module, the operation sound generated by the fan module can be canceled by the antiphase sound information. Through this, the operation sound of the fan module may be restricted from being transmitted to the user's ears.
When sound is input from the user to the microphone 560 of the audio signal processor 550 and the operation of the fan module of the mask apparatus 2 is detected by the sensor portion 530, the conversation mode (S200) may be activated (S200).
Alternatively, the user may directly control the operation of the mask apparatus 2 and select the conversation mode (S200). In addition, the user may select an operation mode by calling a conversation mode.
When the mask apparatus 2 operates in the conversation mode (S200), the rotation speed of the fan module of the mask apparatus 2 may be reduced (S210). Operational noise of the fan module that may be generated by the fan module may be minimized by reducing the rotation speed of the fan module. In addition, it is possible to prevent excessive supply of air by the fan module when a user has a conversation.
After the rotation speed of the fan module decreases, the user's sound can be received through the microphone 560 (S220). The user's voice input through the microphone 560 may be stored in the information storage portion 510 of the mask apparatus 2. The controller 500 can determine frequency information of the user's sound based on the sound information stored in the information storage portion 510. When the frequency of the sound input from the user is low, the controller 500 can recognize accurate sound information by amplifying the frequency of the sound.
The user's sound input through the microphone 560 may be output through the first speaker 570 (S230). The sound output through the first speaker 570 may be output as an amplified sound by resonating in the first resonance spaces 611a and 612a of the mask apparatus 2. The controller 500 may adjust the frequency of the sound output from the first speaker 570 so that the sound output from the first speaker 570 can be amplified in the first resonance spaces 611a and 612a, and may outputs the sound.
When the wireless communication portion 520 of the mask apparatus 2 transmits and receives sound information to and from the terminal, sound is input from the user to the microphone 560 of the audio signal processor 550, and the operation of the fan module of (2) is detected by the sensor portion 530, the communication mode (S300) may operate (S300).
Alternatively, the user may directly control the operation of the mask apparatus 2 to select the communication mode (S300). In addition, the user may select an operation mode by calling the communication mode.
When the mask apparatus 2 operates in the communication mode (S300), the rotation speed of the fan module of the mask apparatus 2 may be reduced (S310). Operational noise of the fan module that may be generated by the fan module may be minimized by reducing the rotation speed of the fan module. In addition, it is possible to prevent excessive supply of air by the fan module when a user has a conversation.
After the rotation speed of the fan module decreases, the user's sound can be received through the microphone 560 (S320). The user's sound input through the microphone 560 may be stored in the information storage portion 510 of the mask apparatus 2.
The user's sound information stored in the information storage portion 510 is transmitted to the terminal by the wireless communication portion 520, and the sound information of the terminal may be received by the wireless communication portion 520 to the information storage portion 510 (S330). The terminal may communicate with the wireless communication portion 520 to transmit and receive sound information. The sound information of the terminal transmitted through the wireless communication portion 520 and the sound input from the microphone 560 may be stored in the information storage portion 510.
The controller 500 may output the sound information of the terminal and the user's sound stored in the information storage portion 510 to the second speaker 580 (S340).
Sound input through the microphone 560 may be transmitted to the terminal, and sound information transmitted from the terminal may be transmitted to the mask apparatus 2 and transmitted to the second speaker 580 through a communication network in real time. The second speaker 580 further outputs the user's sound, so that it can be confirmed whether the user's voice is transmitted to the other party on the call. The mask apparatus 2 can communicate with a terminal, allowing a user to make a phone call in a state of wearing the mask apparatus 2.
Sound information about music is previously stored in the information storage portion 510, or sound information about music is transmitted through the wireless communication portion 520, and when an operation of the fan module of the mask apparatus 2 is detected by the sensor portion 530, the music listening mode (S400) may operate (S400).
Alternatively, the user may directly control the operation of the mask apparatus 2 to select the music listening mode (S400). In addition, the user may call a music listening mode to select an operation mode.
When the mask apparatus 2 operates in the music listening mode (S400), the rotation speed of the fan module of the mask apparatus 2 may decrease (S410). Operational noise of the fan module that may be generated by the fan module may be minimized by reducing the rotation speed of the fan module.
Sound information about music may be received from a terminal or a server through the wireless communication portion 520 (S420). Sound information about music received through the wireless communication portion 520 is stored in the information storage portion 510, and the stored music information can be recognized by the controller 500. Alternatively, information on music previously stored in the information storage portion 510 may be recognized by the controller 500.
When the sound information about the music is recognized, the controller 500 can output the sound information about the music to the second speaker 580. The controller 500 may adjust the frequency of the sound output from the second speaker 580 so that the sound is amplified in the second resonance spaces 631a and 632a and output to the external space.
Meanwhile, when the operation mode is not detected, the operation of the mask apparatus 2 is turned off to save power of the mask apparatus 2.
A mask apparatus 3 according to another embodiment of the present disclosure is characterized in that a portion of the mask apparatus according to an embodiment of the present disclosure is modified. Some components included in the mask apparatus 3 according to another embodiment of the present disclosure may be the same as those included in the mask apparatus according to one embodiment of the present disclosure. Therefore, descriptions of some components included in the mask apparatus 3 according to other embodiments of the present disclosure may be understood by being replaced with descriptions of the same components included in the mask apparatus according to other embodiments of the present disclosure.
Referring to
The first speaker 570 according to another embodiment of the present disclosure may be located under the mask body 10, and the second speaker 580 may be located on both sides of the mask body 10. The sound output from the first speaker 570 may be the sound input through the microphone 560. The sound output from the second speaker 580 may include sound information input through the microphone 560, previously stored sound information, sound information about music, or the like.
The first speaker 570 may be installed to be exposed toward the rear surface of the mask body 10. The sound output from the first speaker 570 may be resonated in the second boundary space B2s formed between the user and the mask apparatus 3 and output to the front of the mask apparatus 3.
Based on the rear surface of the mask apparatus 3, a first boundary space B1s may be formed on the outer circumferential surface of the sealing portion 40, and a second boundary space B2s may be formed on the outer circumferential surface of the mask body 10. A first boundary space B1s may be defined inside the first boundary space B1s, and a second boundary space B2s may be defined between the first boundary space B1s and the second boundary space B2s. A user's nose and mouth may be located in the first boundary space B1s, and a microphone 560 may be installed. When the mask apparatus 3 is worn on the user's face, the second boundary space B2s may be formed between the user's face and the mask apparatus 3. When the mask apparatus 3 is in close contact with the user's face, the second boundary space B2s may form an airtight space. When the second boundary space B2s forms an airtight space between the user's face and the mask apparatus 3, the second boundary space B2s may form a resonance space where sound can resonate. At this time, the second boundary space B2s may be defined as a third resonance space.
The mask apparatus 3 may include a front opening 600 and a rear opening 640. The front opening 600 may be formed in the mask body cover 20, and the rear opening 640 may be formed in the mask body 10. The front opening 600 and the rear opening 640 may communicate with each other. The front opening 600 may include a front opening 601 on one side and a front opening 602 on the other side. The rear opening 640 may include a rear opening 641 on one side and a front opening 642 on the other side.
A connection duct 610 may be included between the mask body 10 and the mask body cover 20 to communicate the front opening 600 and the rear opening 640. The connection duct 610 may extend from the mask body 10 toward the mask body cover 20 or may extend from the mask body cover 20 toward the mask body 10. When the mask body 10 and the mask body cover 20 are coupled, the front opening 600 and the rear opening 640 may communicate with each other by the connection duct 610. A connection space for connecting the front opening 600 and the rear opening 640 may be formed inside the connection duct 610.
The sound output from the first speaker 570 may resonate within the second boundary space B2s. Sound resonated within the second boundary space B2s may pass through the rear opening 640 and be output to the front opening 600. Sound transmitted from the rear opening 640 toward the front opening 600 may be amplified in the connection space and output to the front opening 600. In other words, the sound output from the first speaker 570 is firstly amplified in the second boundary space B2s, then passes through the rear opening 640, is secondarily amplified in the connection space, and then may be output to the external space through the front opening 600.
The second speaker 580 may be installed to be exposed toward the rear surface of the mask body 10. When the second speakers 580 are disposed on both sides of the mask body 10, sound output from the second speakers 580 can be quickly transmitted toward the user's ears.
According to the present disclosure, while minimizing power consumption of the first speaker 570, it is possible to output a loud sound to the front of the mask apparatus 3. In addition, since a resonance space is formed in the remnant space of the mask apparatus 3, sound output from the first speaker 570 can be amplified and the mask apparatus 3 can be designed optimally.
Although the present disclosure has been described in detail through representative embodiments, those skilled in the art will understand that various modifications are possible to the above-described embodiments without departing from the scope of the present disclosure. Therefore, the scope of the present disclosure should not be limited to and not be defined by the described embodiments, and should be defined by all changes or modifications derived from the claims and equivalent concepts as well as the claims to be described later.
