The present invention relates to an earphone device for a portable information device, and more particularly, to a waveguide type earphone device that provides a high-quality sound system free from electromagnetic waves and easy to carry and for which bass is reinforced.

As is well known, there is a rapid increase in the number of people using portable information devices (hereinafter referred to as "portable information devices") such as mobile phones, MP3 players (MP3P), PMP, PDA, digital camera.

In addition, such a portable information device is essentially accompanied by earphones that enable the user to receive music or other voice information stored in the device.

In addition, such earphones may simply receive voice information, but recently, a number of earphones to which a microphone device is added have been released to input voice information into a portable information device.

In general, earphone is an abbreviation of earphone receiver, crystal receiver is a structure that operates the diaphragm using piezoelectric effect of crystal element, and magnetic receiver operates the diaphragm by flowing voice current through the coil. It is structure to let.

In addition to the type that directly plugs into the ear canal, it is also worn on the head, which is called a headphone (headphone).

1 is a perspective view illustrating a state in which a widely used earphone is coupled to a mobile phone which is a kind of portable information device, and the general structure of the existing earphone is described as follows.

Existing earphone has a connection jack 10 which is mechanically and electrically connected to the main body of a portable information device such as a mobile phone 500, a wire part 11 connected to one end of the jack part, and a sign language connected to the other end of the wire part. Receiver 12 and a transmitter 13 disposed in the middle of the wire part 11.

Inside the transmitter 13, a microphone for inputting a caller's voice is embedded, and a speaker unit is built in the receiver.

However, such a conventional earphone has no choice but to expose the head of the human body to electromagnetic waves generated by the speaker device because the speaker device for generating sound is embedded in the earpiece inserted into the ear.

That is, the conventional earphone is urgently improved because the electromagnetic wave generated from the transducer inside the earphone directly affects the human brain wave.

On the other hand, the existing earphone is limited in its shape, there is also a disadvantage that the string is thin, the twist easily occurs.

For reference, electromagnetic waves are a form of energy generated by the use of electricity and are synthesized waves of an electric field and a magnetic field. Electromagnetic waves are emitted from the electric machinery and equipment in use around us. Electric wave is the space where the force of electricity is vertical, expressed in volts per meter (V / m), and the magnetic field wave is the space where the force is horizontal. Is usually expressed in milligaus (mG).

And, the electromagnetic wave is 60Hz, ultra low frequency (0 ~ 1kHz), low frequency (1k ~ 500kHz), communication frequency (500kHz ~ 300MHz), microwave (300MHz-300GHz) according to the frequency (number of vibrations per second). Infrared, Visible, Ultraviolet, X-ray, and Gamma-rays increase in frequency, and double-low and low-frequency electric fields and magnetic fields are generated. Men have been reported to have fewer sperm counts and women may be the cause of menstrual irregularities and birth defects. In addition, in severe cases, brain tumors can be caused, and the WHO has investigated the harmful effects of electromagnetic waves.

On the other hand, in the case of conventional earphones, the speaker is very small compared to the general speaker, and has a limitation that can be made very compact, and is vulnerable to the bass region, which is the most important factor in determining the sound quality, so the bass region when listening to music or other AV The sound is so distorted that it degrades the sound quality, and the reproducibility of most bass areas is poor when watching movies.

Example 6

FIG. 7 is a perspective view of an earphone device according to a sixth embodiment of the present invention. Since the internal sound system is configured to provide high-quality sound with low sound reinforcement as in the above-described embodiments, in order to avoid unnecessary duplication of explanation. The description of this part is omitted, and only the structure unique to this embodiment is described.

The earphone device for a portable information device according to the present embodiment also includes a earphone main body 100, a connection jack 200, a waveguide 300, and a receiver 400.

In addition, referring to FIG. 7, in the embodiment, the earphone jack 100 is rotated and the position is out of position in the state where the connection jack 200 of the earphone body 100 is inserted into the jack connection hole 500a of the portable information device. The feature is that fastening means are provided to prevent this.
