Description

Earphone convenient to it is fixed

Technical Field

The invention relates to the technical field of earphones, in particular to an earphone convenient to fix.

Background

The earphone is a pair of conversion units which receive the electric signals sent by the media player or receiver and convert the electric signals into audible sound waves by using a loudspeaker close to the ear. The headset is typically detachable from the media player and utilizes a plug connection. The advantage is that the user can listen to the sound independently without influencing other people; can also isolate the sound of the surrounding environment, and is very helpful for people who use in noisy environment such as a recording studio, a bar, a journey, sports, and the like. The earphone is originally used for telephone and radio, but with the prevalence of portable electronic devices, the earphone is often used for mobile phones, walkmans, radios, portable electronic games, digital audio players, and the like.

However, in the prior art, since the earphone is in a state that the opening of the external ear canal is tightly blocked by the earphone for a long time, high-volume audio sound pressure directly enters the ear to damage the hearing, so that the hearing is not restored, and the earplug is in close contact with the ear canal when in use, so that the ear is uncomfortable after long-time use, and the ear is red and swollen and generates heat.

Disclosure of Invention

The invention aims to solve the problems that in the prior art, an earphone directly boosts and inputs audio into an ear, unrecoverable hearing damage can be caused after the earphone is used for a long time, ear discomfort is easily caused, and the ear is red, swollen and heated.

In order to achieve the purpose, the invention adopts the following technical scheme: an earphone convenient to fix comprises a shell and a connecting wire, wherein a groove is formed in the shell in a penetrating mode, an earplug is connected in the groove in a sealing and sliding mode, a cavity is formed in the earplug, a telescopic block is connected in the cavity, one end of the telescopic block penetrates through the inner wall of the cavity and is fixedly connected with the shell, an air outlet and an air outlet are respectively formed in the cavity, close to the side wall and the top wall of the telescopic block, penetrating through the earplug, of the telescopic block, the air outlet and the air outlet are respectively connected with one-way valves in opposite directions, a sliding block of a T-shaped structure is sleeved outside the telescopic block, and a sliding groove is formed;

the earphone is characterized in that a player is arranged at one end, close to the exhaust port, of the telescopic block, the player is fixedly connected with a connecting wire, an electromagnet is connected in the sliding block, the electromagnet is electrically connected with a lead, the other end of the lead is electrically connected with the connecting wire, a thermal lantern ring is sleeved on the outer wall of the earplug, the thermal lantern ring is connected with a thermistor, and the thermistor is connected with the electromagnet in series.

In the earphone convenient to fix, the telescopic block 6 is made of giant magnetostrictive material, one end of the shell, which is close to the telescopic block, is provided with a pressure-sensitive elastic sheet, and the pressure-sensitive elastic sheet is made of piezoelectric material and is electrically connected with the electromagnet.

Compared with the prior art, the invention has the advantages that:

1. when the earphone is used, when the earphone is not used, the player and the connecting wire in the earphone are not electrified, so that the electromagnet electrically connected with the earphone is not electrified, the telescopic block keeps the original length, and the earplugs are completely positioned in the grooves to play a role in storage, so that the outer edges of the earplugs are prevented from being exposed in the air for a long time, and the ear canals are prevented from being polluted by bacteria when the earphones are used;

2. when the super-magnetostrictive material is used, the connection wire is connected with the electromagnet in a conducting manner, so that the electromagnet is electrified, magnetized and magnetizes the telescopic block, the telescopic block made of the super-magnetostrictive material is axially elongated, gas in the cavity is heated by heat release according to a magnetocaloric effect in the magnetizing process, the hot gas is released after the telescopic block is elongated, and the processes of heat insulation and magnetization and isothermal heat conduction are performed;

3. when the telescopic block extends, the earplug is pushed to be released, the earplug can be plugged into the ear canal to realize a fixing effect, the two ends of the telescopic block completely abut against the two ends of the cavity, and the player on the telescopic block is directly connected with the separation layer on the side wall of the earplug, so that sound in the player is directly transmitted into the ear through the solid, and the sound listening effect is improved;

4. when the ear canal is red and swollen or becomes hot, the temperature at the ear plug rises, and the thermistor fixed inside is disconnected from the connection wire of the electromagnet, so that the advantage is that on one hand, the telescopic block made of the giant magnetostrictive material retreats to enable an air layer to be separated between the player and the side wall of the cavity, at the moment, sound passes through the air layer and the inner wall of the ear plug in sequence during transmission, and at the moment, high-volume audio sound pressure entering the ear is weakened, so that the damage to the eardrum is reduced;

5. meanwhile, because the electromagnet is not electrified and magnetized, the telescopic block demagnetizes and absorbs heat, so that the gas in the cavity is cooled, the gas in the cavity transfers the temperature to the earplug, the temperature of the earplug is reduced, and the effect of cold compress on the ear is realized. And because the earplug is airtight to the duct for absorb the gas in the cavity and form a negative pressure after the air cooling, make the earplug still keep self fixing in the duct position when the telescopic block moves backward, avoid the earphone to drop, influence the use.

6. The shell is provided with the pressure-sensitive elastic sheet, when the external noise is high, because the shell is positioned in a place which is in a downtown state or has high traffic flow, the volume can be increased unconsciously by a user, the volume is too high, and a load on the eardrum is generated. So that the noise-reducing device can be used when the external noise is high.
