Description

Wearable acoustic device {WEARABLE ACOUSTIC DEVICE}

The present invention relates to a wearable acoustic device, and relates to an acoustic device capable of delivering rich and three-dimensional sound to a user wearing such a wearable acoustic device, and increasing exercise efficiency based on the user's heart rate.

In general, the sound that a person hears is transmitted in the form of waves, and the frequency range of the sound that can be heard is about 20Hz to 20000Hz, which can be seen as a wide range. In addition, such a wide range of frequency domains may be subdivided into various ways according to the characteristics or effects of each frequency domain, and various feelings or effects on a person may be given along with the BPM (Beat Per Minute) of a sound or sound source. For example, a sound in the low frequency range that includes a range of about 150 to 300 Hz can convey a high sense of density to the listener, and a sound that includes a range of about 3000 to 6000 Hz is a great way for the listener to feel calm or noisy. Can have an effect. With reference to the above example, when sounds of various sound ranges are output and transmitted to a single speaker device, the three-dimensional effect and richness of the sound are relatively lower than when configured with multiple speakers. Conventional portable acoustic devices have only one speaker or one channel that transmits sound to each of the user's ears, so it is difficult for the user to provide rich sound unless a separate sound device consisting of multiple channels is provided. There was this. In addition, when the high-pitched sound is listened to through earphones or the like over a certain size or over a long period of time, there is a problem that hearing loss may occur or discomfort such as headache may be caused.

In addition, in relation to the BPM of sound or sound source, for example, if the listener listens to music of about 120 to 147 BPM, the use of the body may increase, so the efficiency during exercise may be increased, and the music of about 60 to 80 BPM. In the case of listening to lactic acid, the rate of decomposition of lactic acid in the body can increase and stress can be reduced.For example, it can help in situations where rest and exercise finishes are in progress.In addition, grasping the physical state according to the situation occurs directly in the body. It can be said that it is accurate to measure the vital signs.

Here, if the above-described characteristics of the BPM are utilized well, the listener may increase exercise efficiency as in the above-described example, but even if the listener is aware of the effect of each BPM, the heart rate, etc., is self-regulated in order to generate an accurate effect in a necessary situation. There is a problem in that it is difficult to determine a physical state by measuring a bio-signal to be included, and accordingly change a sound source and perform an exercise.

The wearable acoustic device 100 and the acoustic device 110 shown in FIGS. 1 and 2 are according to an embodiment, and their components are not limited to the embodiments shown in FIGS. 1 and 2, and are required. Some components may be added, changed, or deleted according to the requirements.

The sound device 110 may transmit sound to the user through the vibration unit 101 and the speaker unit 102, and the sound device 110 may be configured in plural.

Here, the vibration unit 101 may output a vibration corresponding to the sound data, and the speaker unit 102 may output a sound corresponding to the sound data.

The fixing member 120 may fix the acoustic device 110 to the user's body in close contact with the user's body.

In one embodiment, referring to FIG. 3A, the fixing member 120 may be formed in a band shape, and may be manufactured using a material having elasticity such as fabric or silicone. In addition, the fixing member 120 may be formed to be detachable from the acoustic device 110 described above. However, the shape or material of the fixing member 120 is not limited to the above-described embodiment, and a cured material having no elasticity may be used.

3A and 3B are views showing a state in which the acoustic device 110 and the fixing member 120 are coupled to each other according to an exemplary embodiment of the present invention.

When describing the relationship between the sound device 110 and the fixing member 120 described above with reference to FIGS. 3A and 3B, the sound device 110 may be configured as a pair, and both sides of each sound device 110 As the fixing member 120 is coupled, as a result, a pair of the acoustic device 110 and the fixing member 120 may be coupled to each other to be connected.

In FIG. 3B, an example of a state in which a user wears the wearable acoustic device 100 illustrated in FIG. 3A is shown. When the user wears the wearable sound device 100, each sound device 110 may be located at the top of the user's ear (for example, a temple part), but the number and placement of the sound devices 110 The location is not limited to what is represented in FIG. 3B.

The vibration unit 101 and the speaker unit 102 that may be included as components of the acoustic device 110 may be described in detail with reference to FIGS. 4A to 4C.

4A to 4C are views for explaining the shape of the acoustic device 110 according to an embodiment of the present invention.

Referring to FIG. 4A, the acoustic device 110 according to an embodiment of the present invention may include a vibration unit 101 and a speaker unit 102 for transmitting sound to a user. In this embodiment, a vibration unit It consists of one and two speaker units (102). However, the present invention is not limited thereto, and each of the vibration unit 101 and the speaker unit 102 may be composed of one or more.

In one embodiment, the vibration unit 101 may be in close contact with the user's ear upper portion or the temple portion (see FIG. 3B) by the above-described fixing member 120. In addition, the vibration unit 101 and the speaker unit 102 may amplify and output a preset frequency range for each of the vibration unit and the speaker unit. First, the vibration unit 101 may be set to transmit a high frequency region of the frequency region of sound transmitted to the user through vibration. For example, the vibration unit 101 may deliver a sound having a frequency of 6 to 12 KHz to the user. By transmitting a sound corresponding to a relatively high frequency to the user through the vibration unit 101, it is possible to prevent the user from generating an uncomfortable phenomenon that may occur when a high sound is heard as a general sound (transmission through sound waves in the air). In addition, the vibration for the vibration unit 101 to transmit sound to the user may be made through a vibrator or an element that performs a function equivalent thereto, but is not limited thereto.

Next, referring to FIG. 4B, the speaker unit 102 may be arranged to face the user's ear when the sound device 110 is worn by the user by the fixing member 120, and as shown in FIG. When composed of dogs, each of the speaker units 102 may output sound toward different directions. In addition, the speaker unit 102 may be set to transmit a medium or low frequency region to a user through vibration.

Therefore, as shown in FIG. 4A, when the acoustic device 110 is configured with three channels through one vibration unit 101 and two speaker units 102, sound can be output in a total of three directions, and the user Can feel the three-dimensional effect and richness of sound through this sound transmission method. In addition, it is possible to further increase the three-dimensional effect of the sound by setting the three channels to output sounds in the high-pitched, mid-pitched, and low-pitched areas, respectively. (For example, the vibration unit 101 is a high-pitched area and a speaker unit 102). The two channels of each output the mid-range and the low-pitched range)

In addition, in the case where the speaker unit 102 of the acoustic device 110 is composed of two, one of the speaker units 102 directs the sound of the frequency band that the user wants to listen to in the inner auricle as shown in FIG. 4B. The other speaker unit 102 may be set to output sound in a frequency band determined to have a relatively small weight to the outside of the auricle. In the above embodiment, a case in which the speaker unit 102 is composed of two has been described, but the number of the speaker units 102 is not limited thereto, and the direction in which each speaker unit 102 is directed for sound output is also limited thereto. It doesn't work.

In addition, the acoustic device 110 may not be exposed to danger due to blocking from an external situation by taking a form that is not directly mounted on the ear.

Referring to FIG. 4C, the acoustic device 110 transmits a biosignal detection unit 103 that detects a biosignal including a user's heart rate and the detected biosignal to a user terminal, and transmits the biosignal from the user terminal. It may include a communication unit 104 for receiving the sound data selected based on.

Here, the biosignal detection unit 103 may detect a biosignal of a user through an electric means or a method using light. For example, an electrode may be used to detect a user's electrical signal, and the user's pulse may be sensed through an infrared projection method, and the heart rate may be measured based on the detected pulse.

In one embodiment, the acoustic device 110 may measure the user's heart rate by detecting the user's bio signal through the bio-signal detection unit 103, and output acoustic data selected based on the measured heart rate data to the user. You can do it or recommend it. At this time, the selection or recommendation of the sound data may be performed through a user terminal connected to the sound device 110 through wireless communication, and the sound device 110 based on the bio signal detected by the bio signal detection unit 103 It can also be done on its own. In addition, by detecting the user's bio-signal, the user's exercise state can be identified, and information including the user's calories burned, exercise distance, and exercise time can be delivered to the user. The user's state information may be guided by voice through the microphone shown in FIG. 4C or through a user terminal connected to the sound device 110 through wireless communication.

In addition, the wearable acoustic device 100 may determine the user's exercise state through the above-described user's heart rate measurement configuration, and select and output or recommend acoustic data based on the identified user's exercise state.

In this regard, the wearable acoustic device 100 according to an embodiment of the present invention may bring about an effect of increasing exercise efficiency to a user. For example, by measuring the user's heart rate through the biosignal detection unit 103, it is possible to determine what state the user is in, and when it is determined that the user is exercising (e.g., the user's heart rate is 110 BPM). Above), the acoustic device 110 may output a sound source corresponding to a range of about 120 to 147 BPM. When a user listens to a sound source with a high BPM corresponding to the above-described range during exercise, the actual exercise intensity can be increased by about 15%, and accordingly, cardiorespiratory endurance, muscular endurance, and muscular strength are additionally improved. . In addition, when it is determined that the user is in the finishing stage or the rest stage after exercising by measuring the heart rate (for example, the user's heart rate enters 50-70 BPM), the acoustic device 110 has a relatively medium and low speed of about 60 It can output a sound source of ~80 BPM. When a user listens to such a sound source of medium and low speed BPM, the rate of decomposition of lactic acid accumulated in the user's body may increase and stress may be reduced, thereby reducing fatigue and preventing injury after exercise.

The user terminal illustrated in the present invention may execute an application that performs a specific function and may correspond to a device including a touch display device. For example, the user terminal may correspond to a smartphone or a tablet PC. On the other hand, these examples are not intended to limit the scope of the present invention, and if a device is configured including a touch display device capable of executing a specific application and recognizing a user's touch input, the user terminal according to the present invention Should be interpreted as.
