Abstract
An earphone for convenient use of two persons is provided with an earphone plug capable of being plugged into an earphone jack of an electric appliance, an earphone wire extending from the earphone plug, an earphone sound volume adjustment disc connected with the earphone wire, and an earplug, and is characterized in that the earphone sound volume adjustment disc is also provided with an auxiliary earphone jack communicated with the earphone plug. By adopting the earphone for convenient use of two persons, when the other person needs listening, the other earphone can be plugged into the auxiliary earphone plug on the earphone sound volume adjustment disc, so that two persons can listen at the same time through the earphone, and more convenience is provided.
Description
Technical field:
The utility model relates to a kind of earphone, particularly relates to a kind of novel earphone of being convenient to double use.
Background technology:
Earphone is to supply the individual to use, and the stereo set that can not bother other people is classified according to its transducing mode, mainly contain the moving-coil mode, electrostatic and etc. magnetic-type.Separating type on the structure, semi open model and closed.From wearing ear type and wear-type are arranged then in form.
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 than higher, and the earphone output that can be mostly on the sound equipment drives, and reliability and durability.
Driver on the magnetic-type earphone is similar to the dynamic planar loudspeakers that dwindles, and it embeds the voice coil loudspeaker voice coil on plane in the frivolous vibrating diaphragm, as printed circuit board (PCB), actuating force is evenly distributed.Magnet concentrates on the one or both sides (push-pull type) of vibrating diaphragm, and vibrating diaphragm vibrates in the magnetic field of its formation.Do not have electrostatic earphone vibrating diaphragm that kind light Deng the magnet earphone diaphragm, but same big vibration area and close tonequality are arranged, it is high not as moving coil earphone efficient, is difficult for driving.
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.Single stator also can drive vibrating diaphragm, but the form of the recommending distortion of two stators is littler.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 costs an arm and a leg, and is not easy to drive, and the sound pressure level that can arrive is also big less than moving coil earphone, but its reaction speed is fast, the various small details of can resetting, and distortion is extremely low.
Electret earphone also is fixed electrostatic earphone, and its vibrating diaphragm itself is exactly that electrostatic field polarization or that launched by the outer polariton substance of vibrating diaphragm polarizes, and does not need Special Equipment that polarizing voltage is provided.Electret earphone has the most characteristics of electrostatic earphone, but electret depolarising gradually needs to change about 5-10 of its life-span.
Several kinds of above-mentioned earphones, its wearing mode generally are following two kinds:
The firstth, wear-type, this wearing mode is more firm, and earphone is general bigger, and the whole ear that covers can be obtained the better tone quality effect, and shortcoming is the comparison heaviness, is not suitable for outdoor use.
The secondth, ear type, this earphone generally have two less earplugs, can be tucked in the ear; The advantage of this earphone is smaller and more exquisite, is easy to carry, and is adopted by the walkman player widely; But it is relatively poor that its shortcoming is a tonequality; And because earplug directly fills in ear, the sound space of not circling round, long-time use meeting works the mischief to hearing.
The utility model content:
The technical problem that the utility model will solve is: often occur the situation that shares a source of sound in the prior art; Such as lovers' trip; Sometimes listen to music or the like with same mp3, generally need be inserted into two jacks of earphone respectively in two people's ears this moment, so that its use.But this has adverse effect very much concerning audio.For this reason, the producer that has is with doing last two earphone jacks, so that insert two earphones simultaneously on the mp3; Meaning say " lovers mp3 "; But this structure can make the structure complexity of mp3 and cost all improve, and can not be used for other electrical equipment in addition, though and have a kind of earphone bifurcated can be inserted on the earphone jack of electrical equipment; But it is cumbersome to carry such device, and is an impediment to attractive in appearance.
For solving the problems of the technologies described above, the utility model provides a kind of novel earphone of being convenient to double use, and concrete technical scheme is following:
A kind of earphone of being convenient to double use; Said earphone has the headset plug that inserts the electrical equipment earphone jack; Earphone cord from the headset plug extension; Connect the earpiece volume adjustment disk and the earplug of earphone cord, it is characterized in that: also have an additional earphone jack of connecting said headset plug on the said earpiece volume adjustment disk.
Preferably, said earpiece volume adjustment disk has rotary volume by-pass cock.
Preferably, said headset plug rear side is provided with the earphone cord buffer body.
Preferably, said earpiece volume adjustment disk has button volume by-pass cock.
The beneficial effect of the utility model is: utilize the described earphone of being convenient to double use of the utility model; When the another one people also needs common listening; Can the another one earphone be inserted on the additional earphone jack on the said earpiece volume adjustment disk; Thereby can make two people use earphone to listen to simultaneously, more convenient.
Description of drawings:
Fig. 1 is the sketch map of the earphone of being convenient to double use that the utility model provided,
Fig. 2 is the sketch map of the earpiece volume adjustment disk of the earphone of being convenient to double use that the utility model provided.
Reference numeral 1-earphone cord wherein, 2-adds earphone jack, 3-volume by-pass cock, 4-headset plug.
Embodiment:
Combine accompanying drawing that the utility model is done further explanation at present.
As shown in Figure 1; A kind of earphone of being convenient to double use; Said earphone has the headset plug 4 that inserts the electrical equipment earphone jack, from the earphone cord 1 that headset plug 4 extends, connects the earpiece volume adjustment disk and the earplug of earphone cord 1; It is characterized in that: also have an additional earphone jack 2 of connecting said headset plug on the said earpiece volume adjustment disk, said earpiece volume adjustment disk has rotary volume by-pass cock 3.
