Embodiment
Below with reference to accompanying drawings embodiments of the invention are elaborated.
Fig. 1 is shown is to use earphone output control equipment pie graph according to the telephone set of the embodiment of the invention.
As shown in Figure 1, the embodiment of the invention is made of following each several part: portable audio device 10; According to the field signal of outside mobile phone 30, unblanking that portable audio device 10 is exported or the playback switch 12,14 of closing; The audio signal that portable audio device 10 is exported is to the loud speaker 16,18 of outside output.
What Fig. 2 was shown is the concrete pie graph of playback switch of the present invention.
With reference to Fig. 2 as can be known, it is made of following each several part: the switching device Q1 that the output of portable audio device is carried out switch control; Utilize the field signal of outside mobile phone 30, make the detection magnetic field iron plate 13 of the driving On/Off of above-mentioned switching device Q1.
Below, with reference to the accompanying drawings, the output control equipment according to the telephone set earphone of the embodiment of the invention that use is had above-mentioned formation is elaborated.
At first, as shown in Figure 1, portable audio device 10 is the audio-frequence player devices that can carry, and earphone 20 connects with it by connector 11.
Above-mentioned earphone 20 is connected with 2 sound equipment output lines by earpiece plug 11, and utilizes a left side/right side output audio signal of loud speaker 16,18 the user.
Simultaneously, be connected with playback switch 12,14 respectively between above-mentioned earpiece plug 11 and the loud speaker 16,18.Above-mentioned playback switch 12,14 externally under the control of field signal, makes the output line On/Off between above-mentioned connector 11 and the loud speaker 16,18.
That is, playback switch 12, if 14 open, loud speaker 16, just 18 can export normal audio signal, the user just can hear audio signal; Playback switch 12, if 14 close, loud speaker 16, just 18 can not export normal audio signal, the user just can not hear audio signal.
This earphone 20 can have this function as a kind of product.That is, the earphone of built-in playback switch 12,14 externally under the control in magnetic field, makes the audio signal On/Off by portable audio device output.
Simultaneously, above-mentioned playback switch 12, if 14 near mobile phone 30, the stool and urine of the field signal that generates from mobile phone 30 can surpass a certain size, just switch can cut out; If the field signal that is generated in the mobile phone 30 size is lower than a certain size, just it can be opened again.
Like this, when mobile phone 30 presses close to be inserted into earphone 20 in the user's ear, according to the degree of pressing close to, the size in the magnetic field that generates from mobile phone 30 will be different, so, if mobile phone 30 is near earphone 20, just can cut out because of the external magnetic field makes playback switch 12,14, if mobile phone 30 leaves earphone 20 certain distances, the external magnetic field will reduce, and playback switch 12,14 just can be opened.
Here, above-mentioned playback switch 12,14 can have a plurality of, and can the while On/Off.But, because therefore mobile phone 30 can only, can only control specific earphone 12,14 On/Off near the specific earphone of filling in user right ear or the left side ear 40 12,14.
Here, 20 on earphone comprises and can be tucked in the user's ear, and the earphone of various kinds that can playing audio signal or headsets etc.
Simultaneously, being used for the equipment of controls playing switch 12,14 On/Off also not necessarily must be mobile phone 30.That is, it also can comprise the equipment that the receiver of receiver, ordinary public telephone machine of ordinary telephone set and PDA etc. can converse.In other example, playback switch of the present invention also can be a relay etc.Above-mentioned playback switch 12,14 also can have the formation that the loud speaker with earphone 20 combines.
Fig. 2 and Fig. 3 are shown is earphone output control equipment pie graph according to the embodiment of the invention.Here, only specific playback switch 14 is described.
With reference to Fig. 2 as can be known, a side line of portable audio device 10 and loud speaker 18 is connected with playback switch 14, and playback switch 14 includes switching device Q1 and magnetic field detection iron plate 13.
Be connected between above-mentioned switching device Q1 and loud speaker 18 1 side lines, export equipment such as connecting relay by switch.This switching device Q1 also can be made of switching transistor or the diverter switches such as transistor with electromagnetic effects.
Simultaneously, pedestal one side of switching device Q1 provides power supply by detecting magnetic field power supply Vcc, and constitutes by detecting magnetic field iron plate 13.If from the outside to above-mentioned detection magnetic field iron plate 13 output magnetic fields, just it can move to static line 15, if eliminated external magnetic field (the N utmost point or the S utmost point), just it can move to original position.Like this, when detection magnetic field iron plate 13 is in original position, provide P1 power supply along with detecting magnetic field power supply Vcc to the pedestal of switching device Q1, switching device Q1 just opens, and loud speaker 18 just can be exported normal sound.This and then, detecting magnetic field iron plate 13 also can be to carry out the switch plate that On/Off switches according to magnetic field size or magnetic sheet.For example, detecting magnetic field iron plate 13 can be on/off switch such as relay, or utilizes electromagnetic force to make contact On/Off with static line 15.
On the other hand, as shown in Figure 3, when earphone 18 during near mobile phone 30 loud speakers 31, above-mentioned earphone 18 just can be closed.The detection magnetic field iron plate 13 that is playback switch 14 is just moved to static line 15 directions, the P2 that is connected with earth terminal, and therefore detecting magnetic field power supply Vcc does not just provide power supply to switching device Q1, has flowed to ground connection GND end by detecting magnetic field iron plate 13.Above-mentioned switching device Q1 just closes, and just can not export the audio signal of being exported from loud speaker 18.
In addition, the user also just can only hear the voice signal of being exported by mobile phone 30 loud speakers 31.
Here, the user can be according to wanting to utilize mobile phone 30 converse left ear or auris dextra, utilizes with mobile phone 30 approachingly, relevant earphone 20 playback switch of filling in the ear 40 12 closed, thereby interrupt output audio signal.And the transfer voice that mobile phone 30 is exported is given the user.
On the other hand, utilization the present invention can also utilize 30 audio signals that specific earphone is exported of mobile phone to eliminate, and in contrast, also can listen the audio frequency signal with earphone on one side, Yi Bian converse.Simultaneously, utilize other people employed mobile phone 30, the audio signal that also earphone can be exported is eliminated, thereby can keep call tone quality.
Simultaneously,, also can control the output of earphone, so earphone not necessarily must be filled in the ear, also can control according to the magnetic field size that is produced in the telephone set.
Simultaneously, according to the degree of closeness of telephone set and earphone, also can control the output of earphone, the sound of being exported from telephone receiver promptly utilizes the other side's sound size also can control playback switch On/Off built-in in the earphone.
To be that the center is introduced according to desirable embodiment of the present invention, by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this invention technological thought so far.Therefore, the technical scope of this invention is not limited to the content on the specification, must determine its technical scope according to interest field.
