Embodiment
Please also refer to Fig. 1 and Fig. 2, it is the present invention's first preferred embodiment.The distance sensing system of mobile communications device of the present invention, include a transducer 1, a comparator 2, a volume controller 3, an Audio Players 4, a timer 5 and a judging unit 10, wherein this transducer is made up of a sensing cell 12 and an arithmetic element 13 again.
See also Fig. 2, operational flowchart for first embodiment of the invention, utilize a timer to send a triggering signal to transducer (as step 110), after this transducer receives this triggering signal, distance (as step 111) with this transducer of detecting and a surface, and handle the back by arithmetic element and export a numerical value to comparator 2 (as step 112), then can by this judging unit 10 detecting mobile phones whether conversing or standby in (as step 113), when mobile phone during in talking state this judging unit can receive incoming call induced signal from the base station, i.e. expression receives incoming call and sends back complex signal to this comparator 2; If do not have, then mobile phone is in holding state, promptly can not receive any incoming call induced signal.Below will explain respectively at the mode of operation that reaches in the standby in the conversation:
1. working as mobile phone converses: default first reference value in this numerical value and the comparator 2 is compared (as step 114), if this numerical value is less than first reference value, then system can send one first alarm signal to this volume controller 3 (as step 116), and this volume controller 3 will downgrade volume (as step 120); Anti-, greater than first reference value, this volume controller will not done any action (as step 117) as if this numerical value.
2. work as mobile phone just in standby: default second reference value in this numerical value and the comparator 2 is compared (as step 115), if this numerical value is less than second reference value, then system can send one second alarm signal to this Audio Players 4 (as step 118), and this volume controller 4 will be heightened volume (as step 121); Otherwise greater than second reference value, this volume controller will not done any action (as step 119) as if this numerical value.
Wherein this Audio Players 4 is used as the ring prompting of playing incoming call/note.And this technological means mainly be used in when mobile phone by folding and unfolding in airtight object the time (as: cell-phone cover, pocket, Bao Baoli), therefore, need the bigger ring prompting of volume, what this moment, transducer 1 was can be by the distance between sensing itself and sealed object in good time heightens volume to remind the user.
This timer 5 sends a triggering signal with timing and carries out sensor operation to make this transducer 1 in addition, makes this transducer 1 need not be ready comparatively power saving at any time.
Please also refer to Fig. 3 and Fig. 4, it is the present invention's second preferred embodiment.It includes a transducer 1, a comparator 2 and a timer 5, and this transducer is made up of a sensing cell 12 and an arithmetic element 13 again.Itself and the different key groups 6 that also include of the first embodiment maximum.
As consult Fig. 4, operational flowchart for second embodiment of the invention, utilize a timer to send a triggering signal to transducer (as step 210), after this transducer receives this triggering signal, distance (as step 211) with this transducer of detecting and a surface, and handle the back by arithmetic element and export a numerical value to comparator (as step 212), default reference value in this numerical value and the comparator 2 is compared (as step 213), if this numerical value is less than or equal to reference value, then system can send an alarm signal so that key groups 6 is pinned (as step 214), and next the sustainable utilization transducer is carried out sensor operation.
Please also refer to Fig. 5 and Fig. 6, it is the present invention's the 3rd preferred embodiment.It includes a transducer 1, a comparator 2, a volume controller 3 and a timer 5, and this transducer is made up of a sensing cell 12 and an arithmetic element 13 again.Itself and not coexisting of the first embodiment maximum include a volume limitations unit 7.
Also see also Fig. 6, operational flowchart for third embodiment of the invention, utilize a timer to send a triggering signal to transducer (as step 310), after this transducer receives this triggering signal, distance (as step 311) with this transducer of detecting and a surface, and handle the back by arithmetic element 13 and export a numerical value to comparator (as step 312), default reference value in this numerical value and the comparator 2 is compared (as step 313), if this numerical value is greater than reference value, to send first alarm signal to volume limitations unit 7, to set one first limiting value (as step 314), make volume controller only can under the volume limiting value that this first limiting value is defined, adjust volume (as step 316); If this numerical value is less than reference value, to send second alarm signal to volume limitations unit 7, to set one second limiting value (as step 315), make volume controller only can under the volume limiting value that this second limiting value is defined, adjust volume (as step 316), therefore volume limitations unit 7 is far and near to set volume range according to measured distance, as: when max volume is 10, if apart from 1cm, then setting volume range is 0～3, therefore, volume controller 3 max volume only can be transferred to 3.So can avoid volume being done the action increase because of careless manipulation.
By this timer 5 triggering signal is sent in timing again and carried out sensor operation to make this transducer 1, after this transducer 1 is detected distance with this surface once more, can obtain another numerical value via computing again, another numerical value and this reference value are compared, if another numerical value is greater than reference value, then the volume maximum only can be set to the first volume limiting value; Otherwise less than reference value, then the volume maximum only can be set to the second volume limiting value as if another numerical value, and wherein this first volume limiting value is more than or equal to the second volume limiting value.
In sum, the distance sensing system and the application process thereof of the mobile communications device that the present invention is provided in above-mentioned preferred embodiment, can improve mobile communications device in the prior art and can't judge automatically that distance between user and communication is with the control volume, the problem of user's mistuning lifting/lowering volume that causes, and then can make this mobile communications device use that more humane more to meet safety required, so the present invention has the value of industry development in fact.
Though the present invention with preferred embodiment openly as above; right its is not in order to limiting the present invention, anyly is familiar with this operator, without departing from the spirit and scope of the present invention; when change and retouching that can be suitable, so protection scope of the present invention is as the criterion when looking the claim person of defining.
