1 is a block diagram schematically illustrating a configuration of an in-ear type mite number detecting device 100 according to an embodiment of the present invention.

In-ear type chewing frequency detection apparatus 100 according to the present invention is a power supply unit 110 for supplying power to the chewing habit correction device, vibration detection unit 120 for detecting the vibration caused by the movement of the jaw in contact with the ear canal surface. ), The feature extractor 130 converts the vibration detected by the vibration detector 120 into a frequency form and extracts the feature of the vibration, and analyzes the vibration characteristic extracted by the feature extractor 130 to detect the number of times of mastication. The mite number detecting unit 140 and the power supply unit 110, the vibration detector 120, the feature extraction unit 130 and the mite number detecting unit 140 are disposed, and includes a seating unit 150 inserted into the ear.

Meanwhile, the in-ear type work count detection device 100 of the present invention may further include a wireless communication module unit 160 for transmitting information on the number of works detected by the work count detection unit 140 to an external receiving device. have. In addition, the support unit 190 may be further connected to the seating unit 150 to support the entire number of chew detection apparatus 100 to maintain a stable fixed state.

The support unit 190 is formed of a member having elasticity such as metal or synthetic resin to support the seating unit 150 in a form of covering a part or the entirety of the wheel. The support part 190 may be in various forms, but preferably, the support part 190 extends from one side of the seating part 150 exposed to the outside in a state where the seating part 150 is inserted into the ear.

The power supply unit 110 supplies power to the vibration detector 120, the feature extractor 130, the chew count detector, and the wireless communication module 160 corresponding to the electrical device. The power supply unit 110 may be the same device included in the seating unit 150, or may be a separate power supply device connected to the seating unit 150 by wire or wirelessly.

The seating part 150 corresponds to a main body inserted into the ear and preferably has elastic rubber, plastic, synthetic resin, and the like, and as shown in FIG. 2 (a), the vibration detecting part 120 and the feature extracting part ( 130, it is preferable that the number of times detection unit 140, the wireless communication module 160 and the power supply unit is disposed in the seating unit 150 (Fig. 2 (a) is not shown in the wireless communication module unit). In particular, the sensor for measuring the vibration of the ear in the vibration detection unit 120 is preferably disposed in a position in contact with the ear canal out of the outer surface of the seating portion 150.

In another embodiment, at least one of the feature extraction unit 130, the chewing frequency detection unit 140, and the power supply unit may not be disposed in the seating unit 150, but may be included in an external device. Can be. In this case, however, the wireless communication module unit 160 that transmits and receives certain signal information from the device inserted into the ear is required.

The main feature of the present invention is to measure the number of times of writing in the device having a form that is inserted into the ear. As an example of a device inserted into the ear, there are a hearing aid, an earphone, and the like, and such a device may include a chewing frequency detecting device 100 according to the present invention.

Figure 2 (a) is a perspective view schematically showing each configuration in the state in which the in-ear type chew number detecting apparatus 100 according to the present invention is inserted into the ear, Figure 2 (b) is the in-ear type of the present invention An example of the support 190 for supporting the main body of the chewing frequency detection apparatus 100 of FIG.

2 (a) shows an intermediate step in which the seating portion 150 is inserted into the ear. There is a side (S) that is exposed to the outside even when inserted into the ear from the seating portion 150, the display unit for displaying the number of mastication may be disposed on this side.

Looking at Figure 2 (b), the support portion 190 supports the seating portion 150 in the form of wrapping a portion or the entire wheel. The support 190 has a form extending from one side (S) of the seating portion 150 exposed to the outside in a state in which the seating portion 150 is inserted into the ear. On the other hand, the support 190 is preferably composed of a member such as a synthetic resin and / or metal having elasticity.

The vibration detector 120 of the present invention measures the vibration of the surface of the ear canal. The vibration detector 120 includes a sensor that can detect vibration. After the vibration is detected by the vibration sensor, the feature extractor 130 converts the vibration into an electrical frequency form, and detects a frequency characteristic unique to the vibration.

Furthermore, sensors such as piezo film sensors that convert vibrations directly into electrical data can also be used. Also in this case, the feature extractor 130 detects a feature by converting an electrical signal of the piezo film sensor into a vibration waveform.

The vibration detector 120 of the present invention preferably includes at least one piezo film sensor 121 to detect vibration detected on the surface of the ear canal.

Furthermore, the piezo film sensor unit 121 includes a plurality of piezo film segments, and the plurality of piezo film segments are disposed on a surface in contact with the ear canal, and each piezo film segment preferably measures chewing.

The inner ear has a hollow shape of a circular column. Since the inner ear is different in each person and there are various bends, the measuring sensor may not be able to perform accurate measurement depending on the area to be measured. Accordingly, the present invention constitutes the vibration detector 120 with a plurality of piezo film segments. If vibration is measured with each piezo film segment, at least one piezo film segment is capable of accurate vibration measurements.

Incorrectly measured vibration data is preferably removed beforehand. Therefore, the feature extractor 130 measures a pulse signal that appears when converted into an electrical signal for vibration, and removes the mastication signal having an abnormal upper and lower amplitude through filtering, and detects only a valid mastication signal.

To this end, the feature extractor 130 may further include an effective data detector 131 for detecting noise-free data among the mastication signals measured in the plurality of piezo film segments.

Alternatively, the valid data detector 131 may operate. For example, the final effective chew signal may be detected by averaging the remaining values, excluding the measured value with extreme noise in the measured values of the entire piezo film segment.

The authoring number detecting apparatus 100 according to the present invention may further include a display unit 170 displaying the authoring number detected by the authoring number detecting unit 140. The display unit 170 may be implemented in a separate device spaced apart from the seating unit 150. If the chew number detecting apparatus 100 is configured in one piece to be inserted into the ear, the display unit 170 is disposed on one side of the seating unit 150 exposed to the outside in the state in which the seating unit 150 is inserted into the ear. It is preferable.

When the piezo film segment is in contact with various parts of the ear canal to measure vibration, the possibility of valid vibration data being extracted from at least one segment becomes very high.

Since the piezo film itself is usually made of a synthetic resin material having elasticity, the piezo film itself can be in close contact with the curvature of the inner wall of the ear canal, and furthermore, the piezo film segments are connected to each other by elastic members so that the piezo film segments are formed. 121) can be in close contact with the position for measuring vibration.

Various embodiments are possible where the piezo film sensor unit 121 is disposed on the seating unit 150. The piezoelectric film sensor 121 may be disposed on the entire surface of the seating part 150 in contact with the outer ear canal wall, the measuring part may be arranged at regular intervals in several groups, or may be arranged like one straight band.

3 (a) and 3 (b) are exemplary views for explaining the arrangement of the piezo film segment of the present invention. Figure 3 (a) shows the shape disposed on the entire outer surface of the seating portion 150, Figure 3 (b) shows that it is disposed in the form of an annular band on the outer surface of the seating portion 150.

 The piezo film sensor unit 121 is disposed on an outer surface of the seating unit 150 that contacts the outer ear, and may be disposed on all or part of the outer surface of the seating unit 150.

Figure 3 (a) shows an example disposed on the entire outer surface of the mounting portion 150. Since the piezo film sensor unit 121 is positioned only at a portion in contact with the ear canal, it is illustrated in a form disposed on a part of the outer circumferential surface of the cylindrical shape.

When the piezo film sensor unit 121 is disposed on a portion of the outer surface of the seating unit 150, it is preferable that the piezo film sensor unit 121 is disposed in the form of one or more annular bands surrounding the outer surface. Of course, the annular band would be in contact with the inner wall of the ear canal. In FIG. 3 (b), the case in which the annular band is one is illustrated, but it is obvious that the band may be composed of a plurality of bands.

3 (a) and 3 (b), the piezo film sensor unit 121 is illustrated as a piezo film segment having a square shape having a predetermined size, but the piezo film segment may have various sizes or shapes. . For example, polygonal forms such as circles, rhombuses, rectangles, triangles, and the like are possible.

The piezo film segments illustrated in FIG. 3 are disposed on the outer side surfaces of the seating part 150, and the piezo film segments do not have separate connected means. In another embodiment, the piezo film segment may be connected by an elastic connecting member.

4 is a form in which the analog vibration signal detected by the feature detection unit is digitally converted when the in-ear type mite number detecting apparatus 100 or the mastication habit correcting system measures the number of mites by measuring the vibration of the ear. Shows.

When a person chews food, vibrations occur on the inner skin surface and space as the jaw moves. A portion marked in a circle in the ear model of FIG. 4 is a position at which the chew number detecting apparatus 100 of the present invention is inserted to measure vibration.

4 shows an example in which vibration is detected by being converted into a frequency form. The diagrams indicate that nine, three, and four authoring operations occur at regular intervals, respectively. Since one chew forms a constant vibration waveform, one period of the vibration waveform corresponds to one chew.

Food chewing varies from person to person depending on the shape and location of the jaw joint, muscle strength or habits. Therefore, in order to accurately detect the number of mastication, it is desirable to know in advance which vibration waveform is shown in each mastication. The user-customized number of times detection device 100 is to be.

To this end, the mite number detecting apparatus 100 according to the present invention analyzes the characteristics extracted by the feature extractor 130 to determine the individual mastication characteristic detection unit 180 for determining the vibration waveform that is the reference of the single mastication according to the user. It is preferable to further include.

For example, when the user inserts the in-ear type chew number detecting apparatus 100 of the present invention into a learning mode before inserting or inserting the ear, and authors food for a certain time, the individual chew characteristic detection unit 180 is a feature extractor ( 130 analyzes the extracted feature and saves the exact waveform that occurs when authoring once. Thereafter, the number of times of food mastication is detected using the stored individual waveforms. Therefore, when the user changes, it is desirable to go through the learning mode again.

The amount of food brought into the mouth is called a single base chew. The object to which the chew number detection apparatus 100 of this invention detects a frequency | count is food and drink of a reference | standard chew amount once. Detecting the number of mastication for the amount of chewing once, detects the number of mastication from the time when food of the first chewing amount is put into the mouth and before the food of the 1 st chewing amount goes to the neck. When the vibration frequency is analyzed, a certain pattern is detected until food is introduced and swallowed. The present invention uses this to detect the number of times for the amount of chewing once.

On the other hand, rather than ingesting the food of one standard chewage amount in the mouth and then eating the next food, rather than ingesting the next food, it is common to write the next food continuously in the mouth when the food of the amount of one time chew is completed to some extent. . Since the number of times of food mastication is preferably detected separately with respect to the amount of one-time mastication, the number of mastication is calculated from the point of time when the food of the first standard mastication amount (the first reference mastication amount) is input, and the next one-time mastication is performed. If the amount of food (second reference chew) is injected, the number of chews should be counted separately from that point. Thus, at the same time, works on the first, second or third reference chew are separately detected.

When the food of the second reference chew is injected while the food of the first reference chew is chewed, the chewing cycle is rested for two to three times. Therefore, if the vibration waveform is detected again more than two or three times, the instant is set as the starting point for the number of times of the second reference chew amount.

On the other hand, discontinuous vibration waveforms may be detected when talking while eating, although not preferred. In this case, it is preferable to provide a device capable of detecting a certain voice in the chew number detecting apparatus 100 of the present invention so as not to set the chew number again during the time when the voice is detected.
