The present invention relates to an implantable device and a noise shielding method performed by the implantable device, and more particularly, to a noise shielding method for outputting a noise-separated signal in order to shield a user's hearing nerve damage due to noise.

In general, in order to listen to sound and communicate a voice signal, an earphone is used by being worn on the ear of a user in a wired or wireless connection with an external device such as an audio device or various mobile devices. Earsets function to allow only the user to listen to sound and to block noise generated around the user.

However, since the earphone is exposed to the outside of the microphone, it is difficult to hear the sound desired by the user in an environment where noise is generated due to the introduction of noise through the microphone, and there is a disadvantage in that it blocks important surrounding sounds. In addition, when repeatedly exposed to noise for a certain period of time every day, the user cannot rule out the possibility of hearing damage due to the accumulation of continuous hearing loss.

Accordingly, in recent years, studies have been conducted to block external noise while the earset is worn, and studies have been conducted to provide filtered sound by filtering the sound required by the user from the external noise.

However, when the standard for external sound required by the user is unclear, and the earset is worn to block external noise, the purpose of filtering becomes meaningless. In addition, it is difficult to cope with each noise environment as the exposed noise environment is different according to the user's tendency to use the ear set.

Accordingly, while solving the above-described problem, there is a need for a method of providing a signal from which noise is removed from among signals collected through an ear set to a user.

The present invention provides a noise blocking method for outputting a danger signal in which noise is separated according to a preset noise level for each user by identifying a frequency band of a danger signal collected through a microphone constituting an implantable device.

The sensor according to an embodiment of the present invention is in close contact with the user's skin, and may measure blood, brain waves, and/or bio-signals related to heart rate in consideration of at least one of the user's skin temperature, humidity, and movement.

1 is a diagram illustrating an overall operation of an implantable device according to an embodiment of the present invention.

Referring to FIG. 1, the implantable device 101 is a small handset designed to be mounted on the ear of the user 103, and is a device that transmits a voice signal by operating a diaphragm using a piezoelectric effect. The insertion type device 101 is classified into an open type, an insertion type, and an earring type, depending on the shape fixed to the ear. Here, it is obvious that the implantable device 101 is a concept encompassing not only conventional earphones, but also headsets and types of earphones having an earphone function. For example, the implantable device 101 may include a wired/wireless hands-free headset, a wired/wireless hands-free earset, a Bluetooth headset, and a Bluetooth earset.

The implantable device 101 may detect noise using a microphone built in the implantable device 101. In detail, the microphone built in the implantable device 101 has a characteristic of receiving a wide range of noises such as car sound, noise sound, music sound, etc. in the working space 102 where noise is generated. When noise is detected through the microphone, the implantable device 101 may collect a danger signal in the work space 102 where the noise is detected. Here, the work space 102 to which the noise is exposed may be a place that causes irregular sound by a noise source existing in a factory site, a construction site, a road, etc.

The implantable device 101 may determine the frequency band of the collected danger signal. The implantable device 101 is a region from the minimum value to the maximum value of the danger signal, and can determine a range of noise generated in the working space 102. Accordingly, the implantable device 101 may set a regulation standard according to the necessity of noise and vibration regulation in the work space 102 and determine the frequency band of the danger signal according to the set regulation standard.

In addition, the implantable device 101 may determine an acceptable noise level of a user wearing the implantable device 101. In detail, the user may have different levels of signals output to the user's eardrum through the implantable device 101 according to the space in which the user is located, the type of work of the user, and working hours. As a result, according to the present invention, the working space 102 to which noise is exposed is different according to the user's tendency to use the ear set, and the level of the signal to be output to the user for each working space 102 may be different.

The implantable device 101 may separate voice and noise constituting the danger signal according to the noise level. The implantable device 101 can separate and eliminate noise from the danger signal through the following method.

① Active control

The implantable device 101 can actively control the danger signal. The implantable device 101 may separate and control the danger signal by automatically changing the frequency level specified for each work space or the noise level in consideration of the noise level. In addition, the implantable device 101 may model the danger signal for each noise level, and separate and remove the received danger signal according to the modeled noise level.

The implantable device 101 may configure an acceptable dB for each user and for each noise-generating operation (hammer operation, welding operation, equipment, …). The implantable device 101 may be configured to be able to actively control signals other than signals set for each user and each task.

② Noise canceling control

The implantable device 101 may perform noise canceling through destructive interference according to the noise level. Noise canceling is a technology that blocks noise by inputting ambient noise through a microphone and then generating destructive interference that cancels the noise in a noise canceling circuit.

Accordingly, the implantable device 101 can separate the voice and noise constituting the danger signal by performing noise canceling. The voice separated from the danger signal can be output to the user, and the noise separated from the danger signal can be removed.

The implantable device 101 may receive the user's biosignal using a sensor built into the implantable device. The sensor included in the implantable device is in close contact with the user's skin, and may measure blood, brain waves, and/or biological signals related to heart rate in consideration of at least one of the user's skin temperature, humidity, and movement.

The implantable device 101 may output a danger signal in which noise is separated based on the user's biometric signal. In detail, the implantable device 101 may adjust the amplitude of the danger signal such that the amplitude of the sound determined based on the noise suppressed by the destructive interference is greater than the amplitude of the suppressed noise. The implantable device 101 may output a danger signal whose amplitude is adjusted to the eardrum of the user 103 through ear fins of the implantable device 101.

The implantable device 101 may interwork with the cloud 104. In detail, the implantable device 101 may transmit data related to a specific time period to the cloud 104. The specific time period may be a period determined as noise among the danger signals collected in the work space. The implantable device 101 may transmit data corresponding to N seconds before and after the signal existing in a specific time interval to the cloud 104.

This may be to use the noise generated in the work space 102 as information for sharing between different users. In addition, the present invention may be used to block noise in advance in consideration of when the user 103 revisits the work space 102 to perform work in the future.

The ear tip 201 may be an end of the insertable device 101 that is directly inserted into the user's ear, made of a comfortable material such as silicone, rubber, etc. that does not cause discomfort to the ear during a long operation.

The cable 205 may have a connection jack 204 formed on each of one side and an opposite side of the cable 205. Each connection jack 204 formed in the cable 205 may be coupled to a connection groove 203 formed in the body 202 of the right ear pin 207 and the body 202 of the left ear pin 207, respectively. Here, the cable 205 may be used for the purpose of separating the right ear pin 207 and the left ear pin 208, respectively, or preventing loss.

The right ear pin 207 and the left ear pin 208 may actively or dynamically reduce noise generated in the work space according to a direction corresponding to the right or left. The right ear pin 207 and the left ear pin 208 are detachable, respectively, and can operate in a dual structure that performs different functions, respectively. As an example, the right ear pin 207 performs a function of a speaker outputting a danger signal from which noise has been removed, and the left ear pin 208 can perform a function of collecting a danger signal in a work space where noise is generated. have.

In the present invention, the right ear pin 207 and the left ear pin 208 do not perform the same function, but operate in a dual structure that performs respective roles, so that an effect of saving power may occur.

The sensor 206 may measure a biosignal related to blood, brain waves, and/or heart rate in consideration of at least one of a user's skin temperature, humidity, and movement. As an example, the sensor 206 is a commercially available product line that can measure a user's bio-signal using an earphone, and may utilize Kyocera, Alps Electric, Bio Surround System, LG Chip-on, and the like. Here, Kyocera is an earphone using a laser blood flow sensor, Alps Electric is a near-infrared spectral sensor that measures scatter, pulse, and anemia, and the Bio Surround system measures the user's brain waves, and the LG Chip-on checks blood flow and heartbeat signals.

That is, the processing unit 302 may perform predictive maintenance using machine learning when abnormal noise occurs while detecting noise in a similar band at all times in the work space.

The processing unit 302 may separate voice and noise constituting the danger signal according to the noise level. The processing unit 302 may remove noise constituting the danger signal in order to perform user-to-user/user-manager communication.

The processing unit 302 may separate the user's voice frequency from the danger signal received through the microphone. The processing unit 302 may remove active noise due to noise tasks. Here, the noise operations may include hammer, welding, noise of the machine equipment itself. The processing unit 302 may attenuate more noise between the corresponding noise section (2 to 6 kHz).

The processing unit 302 may control to maintain a power saving state when it is not in the noise section, and control to enable communication only by operating only one of the pair of ear pins L and R.

The processing unit 302 may transmit the data through communication when a specific band section occurs (threshold value). The processing unit 302 may store the time range before (+) the noise section exceeding the threshold value: the time range before (+) the occurrence, and then transmit it to store as much as the capacity allowed by the memory 305. The processing unit 302 may transmit the time range stored in the memory 305 through the communication unit 306 to the cloud server, and may be used as noise evaluation data after machine learning.

The input unit 303 may collect a danger signal generated from the outside through a microphone built in the ear pin. The input unit 303 may perform a function of enabling communication between users or between users and administrators.

The output unit 304 may output a danger signal from which noise is removed to a user through a speaker embedded in the ear pin. The output unit 304 may perform a function of enabling communication between users or between users and administrators.

In the case of listening to music or the like, the output unit 304 may minimize a burden on hearing by increasing specific sound components for sound quality or performing a volume control function.

The memory 305 may be utilized for predictive maintenance of the implantable device and for storing and managing abnormal shapes of body information. For example, the memory 305 may only need a small amount of capacity for predictive maintenance and storage of body abnormality information.
