Embodiment
Specific embodiments of the present invention are further described in detail below in conjunction with drawings and Examples, but should not limit protection scope of the present invention with this.
See also Fig. 1-A and Fig. 2.Fig. 1-A is a function of mobile communication device calcspar of the present invention.Fig. 2 is the schematic appearance of device for mobile communication of the present invention.In actual applications, device for mobile communication 1 of the present invention can be mobile phone, PDA mobile phone and intelligent mobile phone etc.
Shown in Fig. 1-A, device for mobile communication 1 comprises receiving element 10, receiver 12, loud speaker 14, control unit 16, photoelectricity sensing component 18 and input unit 20.Control unit 16 is coupled to receiving element 10, receiver 12, loud speaker 14, photoelectricity sensing component 18 and input unit 20 respectively.As shown in Figure 2, device for mobile communication 1 has a housing 24, and input unit 20 is built and placed on the housing 24.Again, receiver 12 and photoelectricity sensing component 18 are arranged in the housing 24 and can local expose to the upper surface of housing 24.
Behind device for mobile communication 1 connecting incoming call number, receiving element 10 can be in order to the audio signal of reception sources power generator number end, for example voice or music.Receiver 12 promptly refers to the receiver of device for mobile communication 1.Behind the connecting incoming call number, the user can be with the close receiver of ear to listen to audio signal.Loud speaker 14 promptly refers to the loudspeaker of device for mobile communication 1.
When the user desired the incoming call answering number, the user can be by input unit 20 (for example pressing the key of answering of mobile phone) transfer operation signal to control unit 16.After control unit 16 received from the operation signal of answering key, control unit 16 can be according to the audio signal of described operation signal control receiving element 10 beginning reception sources power generator number ends.Simultaneously, control unit 16 can start photoelectricity sensing component 18 in response to described operation signal.
In first specific embodiment, photoelectricity sensing component 18 of the present invention can be a photodiode.
When the user presses when answering key, the circuit of photodiode is opened immediately.Suppose that at this time the user is not with the close device for mobile communication 1 (such as device for mobile communication 1 is put on the table) of ear, photodiode can be experienced the light source from environment.When supposing that photodiode senses the light source of environment, photodiode can send the light detection signal of representative " 1 " to control unit 16, and at this time control unit 16 meetings are exported the audio signal that is derived from the caller ID end that receiving element 10 be received via loudspeaker.Letter speech, following in this situation, the sounding path of device for mobile communication 1 can automatically switch to loudspeaker, allows the user can very clearly hear the other side's sound.
Yet, if the user at this moment wait pick up device for mobile communication 1 and with receiver near own ear, photodiode just can't sense environment light source or experience very weak light source at this moment.Suppose following in this situation, photodiode sends the light detection signal of representative " 0 " to control unit 16, and then at this time control unit 16 can be exported audio signal via receiver.That is to say, following in this situation, the sounding path of device for mobile communication 1 can automatically switch to receiver by loudspeaker.Under the situation that can hear the other side's sound, the power consumption stream that this automatic shifting function can avoid the loudspeaker sounding to be caused increases, and causes reduce the service time of battery.In addition, after the user pressed end talk key end conversation, control unit 16 can be closed photoelectricity sensing component 18 in response to the operation signal that finishes the talk key generation certainly.Perhaps, after the caller ID end finished conversation, control unit 16 also can be closed photoelectricity sensing component 18 automatically.
In second specific embodiment, photoelectricity sensing component 18 of the present invention can be an infrared ray sensor.
When the user presses when answering key, the circuit of infrared ray sensor is opened immediately, and at this time infrared ray sensor can be triggered with the emission infrared ray.Suppose that at this time the user is not with the close device for mobile communication 1 (being that infrared ray is not interdicted by the user) of ear, infrared ray sensor can send the light detection signal of representative " 1 " to control unit 16.Following in this situation, control unit 16 can be exported the audio signal of caller ID end via loudspeaker.
Yet, if the user at this moment wait pick up device for mobile communication 1 and with receiver near own ear, infrared ray can be interdicted by the user, infrared ray sensor can send the light detection signal of representative " 0 " to control unit 16 instead at this moment.Following in this situation, the sounding path of device for mobile communication 1 then automatically switches to receiver by loudspeaker.
See also Fig. 1-B.Fig. 1-B is the extension function calcspar of device for mobile communication of the present invention.Shown in Fig. 1-B, device for mobile communication 1 further can comprise time detecting unit 22, be coupled to photoelectricity sensing component 18 and control unit 16 between.Time detecting unit 22 is in order to the switching time between detecting loudspeaker and two sounding paths of receiver.
For example, suppose that audio signal is exported via loudspeaker in certain period, in case after photoelectricity sensing component 18 produced the light detection signal of representative " 0 ", 22 of time detecting units can begin to detect described switching time.After reaching default time switching time, the light detection signal of representative " 0 " just can be sent to control unit 16, causes the sounding path to automatically switch to receiver by loudspeaker.The purpose of time detecting unit 22 its designs is to avoid some situation, when for example the user adjusts the gesture of taking receiver momently in using receiver, and the puzzlement that the sounding path of device for mobile communication 1 switches to loudspeaker is at once caused.In addition, this design also can avoid the electric power of device for mobile communication 1 to be consumed meaninglessly.
See also Fig. 3-A.Fig. 3-A is the flow chart of first embodiment of sound switching method of the present invention.Described sound switching method is applicable to device for mobile communication, and device for mobile communication comprises receiver and loud speaker.
Execution in step S100 produces operation signal to start sensing mechanism.Step S100 can produce operation signal by the input unit of device for mobile communication.
Execution in step S102, the sensitive context state also produces corresponding smooth detection signal.In actual applications, variation or the ultrared variation of sensing that step S102 can sense ambient light.
Execution in step S104, according to the light detection signal optionally via receiver or loud speaker output audio signal.As previously described, if the light detection signal of representative " 1 " is produced, then step S104 can be via the loud speaker output audio signal; If the light detection signal of representative " 0 " is produced, then step S104 can be via the receiver output audio signal.
Furthermore, the step S104 among Fig. 3-A can be carried out by the step S1040 among Fig. 3-B ~ S1044.
Among the step S1040, detect the switching time.Refer to the switching time between two sounding paths of loud speaker and receiver above-mentioned switching time.Then, in step S1042, above-mentioned switching time and Preset Time are compared.Afterwards, according to the comparative result of step S1042, step S1044 can optionally export described audio signal via receiver or loud speaker.
The above is preferred embodiment of the present invention only, is not to be used for limiting practical range of the present invention.Be that all equivalences of doing according to the content of the present patent application claim change and modification, all should be technology category of the present invention.
