Abstract

The invention relates to a dimension-adjustable earphone, comprising an earphone plug inserted into an earphone jack of an electric appliance, earphone wires extending from the earphone plug and earplugs connected with the earphone wires. The dimension-adjustable earphone is characterized in that each earplug is internally provided with an unfolding device which can be unfolded toward the outer edge of the earphone when being pressed, the back of the earplug is provided with a key switch which can press the unfolding device, and a case of the earplug is at least made from an elastic and deformable material at a position surrounding the unfolding device. By adopting the dimension-adjustable earphone provided by the invention, the outer edge of the earphone can be regulated according to the sizes of earholes of different people, so that the earphone can be fit with different earholes, and further wearing comfort and firmness are enhanced.

Description

A kind of dimension adjustable earphone
Technical field:
The present invention relates to a kind of earphone, particularly relate to a kind of novel dimension adjustable earphone, belong to the technical field of audio-visual equipment.
Background technology:
Earphone is for the individual, receives the stereo set of voice signal.Earphone is classified according to its transducing mode, mainly contain moving-coil mode, moving iron mode, electrostatic and etc. magnetic-type.On structure, can be divided into semi open model and closed.From wearing formal classification ear type, ear suspension type, In-Ear and wear-type are arranged then.
Earphone is exactly two pronunciation unit that hang on the ear limit the earliest, has developed till now many types, and earphone, earplug, ear-hang and new development bone conduction earphone is out arranged substantially.Headphone is headset type the earliest.
Earplug is that the revolutionary character of earphone development breaks through, and less volume is so that it is very easy to use outside.Ear-hang can be an intermediate product of earphone and earplug, and the characteristics of ear-hang neutralized earphone and earplug pluses and minuses are just worn, and ear-hang is very beautiful.Bone conduction earphone is newer technology, adopts the vibrations principle, by skull sound is directly transferred to the audition maincenter.But this product is not also popularized now. 
Earphone develops into now, topmost pronunciation unit or moving-coil pronunciation unit.Moving coil earphone is the most common, modal earphone, and its driver element is exactly a small-sized moving-coil speaker basically, drives the vibrating diaphragm vibration that is attached thereto by the voice coil loudspeaker voice coil that is in the permanent magnetic field.Moving coil earphone efficient is higher, and the earphone output that mostly can be on the sound equipment drives, and reliability and durability.Electrostatic earphone has gossamery vibrating diaphragm, and by the High Level DC Voltage polarization, the required electric energy that polarizes is transformed by alternating current, also has battery powered.Vibrating diaphragm is suspended in the electrostatic field that is formed by two fixing metallic plates (stator), and when audio signal was loaded on the stator, electrostatic field changed, and drives the vibrating diaphragm vibration.Electrostatic earphone must use special amplifier that audio signal is converted into the voltage signal of hundreds of volts, and the output that is connected to power amplifier with transformer also can drive electrostatic earphone.Electrostatic earphone is expensive, is not easy to drive, and the sound pressure level that can arrive is also large less than moving coil earphone, but its reaction speed is fast, the various small details of can resetting, and distortion is extremely low.
Earphone is now towards wireless and noise reduction development.Wireless headset uses freer, and along with the development of science and technology, Radio Transmission Technology is ripe gradually, has guaranteed the tonequality of wireless headset.The another one reason is exactly the birth of popularizing of mobile phone music function and Bluetooth wireless transmission technology, and Bluetooth wireless earphone just in develop rapidly.
Summary of the invention:
The technical problem to be solved in the present invention is: earphone of the prior art, its size is changeless, can't regulate, and people's ear and earhole vary, especially adult and child, generally have individual difference between man and the Ms, the somebody wears earphone and tends to feel can't fill in too greatly, and other people feel too little and bad being fixed in the earhole.
For solving the problems of the technologies described above, the invention provides a kind of novel dimension adjustable earphone, concrete technical scheme is as follows:
A kind of dimension adjustable earphone, described dimension adjustable earphone has the headset plug of the earphone jack of inserting electrical equipment, earphone cord from the headset plug extension, the earplug of frames connecting with headphone line, it is characterized in that: described earplug inside has the device for spreading that can press and strut to its outer rim, have the key switch of pressing described device for spreading on the back side of described earplug, the shell of described earplug is made by elastic deformable material in the position that surrounds described device for spreading at least.
Preferably, described device for spreading has the main shaft that connects described key switch, is hinged with a plurality of struts towards described earplug outer rim on the described main shaft, and described strut launches by pressing of described main shaft or shrinks.
Preferably, described earphone has the volume adjusting dish at earphone cord.
Preferably, described volume adjusting dish has rotary volume adjusting switch.
Preferably, described volume adjusting dish has button volume adjusting switch.
Beneficial effect of the present invention is: utilizes dimension adjustable earphone of the present invention, can regulate the outer rim size of earphone according to the size of the earhole of different crowd, and the different earhole of can fitting, thus increased comfort and the firmness of wearing.
Description of drawings:
Fig. 1 is the schematic diagram of dimension adjustable earphone provided by the present invention when dwindling,
Fig. 2 is the schematic diagram of dimension adjustable earphone provided by the present invention when amplifying.
Reference numeral 1-earphone cord wherein, 2-earplug, 3-key switch.
Embodiment:
Now by reference to the accompanying drawings the present invention is described further.
Shown in Fig. 1-2, a kind of dimension adjustable earphone, described dimension adjustable earphone has the headset plug of the earphone jack of inserting electrical equipment, earphone 1 from the headset plug extension, the earplug 2 of frames connecting with headphone line, it is characterized in that: described earplug 2 inside have the device for spreading that can press and strut to its outer rim, has the key switch 3 of pressing described device for spreading on the back side of described earplug, the shell of described earplug 2 is made by elastic deformable material in the position that surrounds described device for spreading at least, utilize dimension adjustable earphone of the present invention, can be according to the size of the earhole of different crowd, regulate the outer rim size of earphone, the different earhole of can fitting, thus comfort and the firmness of wearing increased.
