1. A device for relieving headache and pain caused by temporomandibular joint disorders, the device comprising:
a body having a neck band configured to partially surround a neck of a user, first connectors extending straight horizontally and forwardly from both ends of the neck band by first lengths, respectively, and second connectors extending straight upwardly from front ends of the first connectors by second lengths, respectively;
first frequency electrostimulators respectively disposed on the second connectors and configured to come into contact with temporalis muscles, when the body is worn on a head of the user, to apply frequencies to the temporalis muscles; and
second frequency electrostimulators respectively disposed on connected portions between the first connectors and the second connectors and configured to come into contact with masseter muscles, when the body is worn on the head of the user, to apply frequencies to the masseter muscles,
wherein front ends of the first connectors and bottom ends of the second connectors are connected seamlessly, and both ends of the neck band and rear ends of the first connectors are connected seamlessly,
wherein each first frequency electrostimulator comprises a first micro vibrator for applying micro vibrations to each of the temporalis muscles when the body is worn,
wherein each second frequency electrostimulator comprises a second micro vibrator for applying micro vibrations to each of the masseter muscles when the body is worn, and
wherein each first frequency electrostimulator is separate from each second frequency electrostimulator to apply the frequencies to the temporalis muscles and the masseter muscles,
the device, further comprising:
first expansion and contraction parts disposed on the first connectors so as to expand and contract the first lengths of the first connectors respectively in directions of the first lengths;
second expansion and contraction parts disposed on the second connectors so as to expand and contract the second lengths of the second connectors respectively in directions of the second lengths; and
protruding portions respectively disposed and protruding inwardly by given lengths from the connected portions where the front ends of the first connectors and the bottom ends of the second connectors are respectively connected to each other, the second frequency electrostimulators being disposed on inner sides of the protruding portions,
wherein the first connectors are configured to be respectively disposed below ears of the user when the body is worn by the user.
