See also Fig. 1, shown in Figure 2, Fig. 1 is the structure cutaway view of Headphone device first embodiment of the present invention, and Fig. 2 is the structure cutaway view of the loudspeaker unit among Fig. 1.The Headphone device 10 that the present invention's first preferred embodiment provides comprises a housing 11, a loudspeaker unit 12 and one first microphone 13.
Above-mentioned housing 11 is provided with an accommodation space 112, in order to the ccontaining loudspeaker unit 12 and first microphone 13.Housing 11 has one and goes out line 111, and this goes out line 111 and is provided with sender hole (among Fig. 1 not label).
Above-mentioned loudspeaker unit 12 is arranged in the housing 11, and it comprises a vibrating diaphragm 126 (as shown in Figure 2) and a voice guide hole 124.
This vibrating diaphragm 126 is arranged on going out between line 111 and the voice guide hole 124 of housing 11, concrete, this vibrating diaphragm 126 is towards going out line 111;
This voice guide hole 124 is arranged at loudspeaker unit 12 the other end with respect to vibrating diaphragm 126, and in order to conduction sound.
See also loudspeaker unit shown in Figure 2, above-mentioned 12 except voice guide hole 124 and vibrating diaphragm 126, it more comprises a magnetic conductance seat 121, a magnet 122, a magnetic conduction pole plate 123 and a voice coil loudspeaker voice coil 125.
This magnetic conductance seat 121 has a cross section that roughly takes the shape of the letter U.
This magnet 122 is arranged on the interior diapire of magnetic conductance seat 121;
This magnetic conduction pole plate 123 is arranged on the side of magnet 122 away from magnetic conductance seat 121.Form between the madial wall of this magnetic conduction pole plate 123 and magnetic conductance seat 121 and be provided with a magnetic conduction gap (among the figure not label).
This voice coil loudspeaker voice coil 125 comprises a hollow cylinder 1251 and is located on a coil 1252 of an end of hollow cylinder 1251.The end that voice coil loudspeaker voice coil 125 is equipped with coil 1252 is to be inserted into this magnetic conduction gap, and its other end links to each other with vibrating diaphragm 126.
In addition, this voice guide hole 124 is through magnetic conductance seat 121, magnet 122 and magnetic conductive board 123, and is connected with the hollow cylinder 1251 of voice coil loudspeaker voice coil 125.
The operation principle of loudspeaker unit 12 is roughly: the magnetic line of force that magnet 122 produces is passed to magnetic conduction pole plate 123, radially is passed to magnetic conductance seat 121 by this magnetic conduction gap then, constitutes a field circuit thereby be back to magnet 122 by magnetic conductance seat 121 again.When the coil 1252 of voice coil loudspeaker voice coil 125 receives an electric signal polarization, the polarity of the magnetic field of polarity that voice coil loudspeaker voice coil 125 produces and magnet 122 generations is under identical or different situation, can produce the action that repels each other or inhale mutually and make vibrating diaphragm 126 vibrations, and then play out the sound corresponding with the electric signal that receives.
The first above-mentioned microphone 13 is arranged in the housing 11, and covers voice guide hole 124.It should be noted that, the people when speaking except the sound wave that sends via sound channel, because duct is for being communicated with, therefore also will producing identical sound wave in duct, getting final product the sound wave that will come from the duct by this vibrating diaphragm 126 and this voice guide hole 124 and be passed to first microphone 13 with throat.
Further, Headphone device 10 of the present invention also comprises an earplug 14 (as shown in Figure 1).This earplug 14 is arranged on the housing 11, and its shape is can fill in to be fixed in the duct.Earplug 14 comprises a hollow conduit 142, this hollow conduit 142 with go out line 111 and be connected.Concrete, this hollow conduit 142 is connected with the accommodation space 112 of housing 11 via the sender hole that goes out line 111, listen to for the user to duct in order to the transmission sound that loudspeaker unit 12 is play, and the sound wave that produces in user's duct is passed to vibrating diaphragm 126, and be passed to first microphone 13 via voice guide hole 124 and receive, and produce corresponding electric signal.
In addition, Headphone device 10 of the present invention also can comprise a controller 15.This controller 15 is electrically connected with the loudspeaker unit 12 and first microphone 13, is sent to loudspeaker unit 12 playing sound in order to electric signal that will input, and first microphone 13 is received the electric signal output that produces behind the sound waves.Particularly, this controller 15 forms with the loudspeaker unit 12 and first microphone 13 respectively via a plurality of signal transmission lines 152 and is electrically connected.Controller 15 can design according to actual needs in the outside of housing 11 or inner.The preferably, controller 15 can comprise a signal amplifying unit (not shown), carries out processing and amplifying in order to the electric signal that first microphone 13 is produced.
Seeing also shown in Figure 3ly, is the cutaway view of Headphone device second embodiment of the present invention.The Headphone device 20 of second embodiment of the invention, it also comprises a sound insulation element 144 with different being in earplug 14 of first embodiment, for example continuous cover, it is sheathed on the hollow conduit 142, in order to further isolation external environment noise.
Wherein, in being arranged so that first microphone 13 and second microphone 16 is arranged at two spaces of separating respectively of dividing plate 114, thereby can effectively avoid external environment that first microphone 13 is produced noise jamming.Second microphone 16 can form with controller 15 via a signal transmission line 152 and be electrically connected, it receives the electric signal that produces behind the external sounds by hole 116 can be sent to loudspeaker unit 12 via controller 15, listens to for the user and played sound by loudspeaker unit 12.
Further, when controller 15 disposes the signal amplifying unit, can carry out processing and amplifying to the electric signal that second microphone 16 produces, but so that Headphone device 20 double as hearing aidss use.
Further, controller 15 also can be provided with a signal filter, a filter or a numeral (being numerical digit) signal and handle (Digital Signal Processor, DSP) unit (not shown), be used for the electric signal that second microphone 16 produces is removed the background noise (Background Noise) that second microphone 16 receives in the electronics mode, and can make sound more clear.
Be understandable that, also dividing plate 114 can be set in the housing 11, thereby second microphone 16 and first microphone 13 are positioned at same accommodation space.In addition, second microphone 16 is not limited to be arranged in the housing 11, and it also can be set directly at the outside of housing 11.
In sum, Headphone device of the present invention for example is that voice guide hole is set on loudspeaker unit via the structural design to Headphone device, and makes the sound wave in the duct to be passed to first microphone in the Headphone device by this voice guide hole.Thus, can as the existing known techniques main body outside extension microphone is set.Further, Headphone device of the present invention more can be provided with second microphone receiving extraneous sound wave, and the signal amplifying unit of the controller by Headphone device handles, and is passed to loudspeaker unit again, but and make Headphone device in addition the double as hearing aids use, be suitable for practicality more.
The above, it only is preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, though the present invention discloses as above with preferred embodiment, yet be not in order to limit the present invention, any those skilled in the art, in not breaking away from the technical solution of the present invention scope, when the technology contents that can utilize above-mentioned announcement is made a little change or is modified to the equivalent embodiment of equivalent variations, in every case be the content that does not break away from technical solution of the present invention, according to technical spirit of the present invention to any simple modification that above embodiment did, equivalent variations and modification all still belong in the scope of technical solution of the present invention.
