Specific embodiment
Accompanying drawing is combined below by specific embodiment to be described in further detail the present invention.
As shown in figure 1, existing mobile terminal internal structure, including nonmetallic frame 1, antenna body 2, proximity transducer core
Piece 3 and exploring antenna, because exploring antenna is located at around antenna body 2, this design largely occupies mobile terminal
Space.
Embodiment one：
To reduce the mobile terminal inner space occupied by exploring antenna, this example provides the mobile end of another structure
End.
The mobile terminal of this example includes nonmetallic frame 1, antenna body 2, proximity transducer chip 3 and extension bar 4, extension
A part for bar 4 or the overall exploring antenna being extended to for detecting human body near the state of antenna body 2, in order to reduce figure
Space in 1 occupied by exploring antenna, as shown in Fig. 2 the extension bar 4 of this example is embedded in inside nonmetallic frame 1, proximity transducer
Whether chip 3 is used to judge human body near antenna body 2 according to the signal of the extension transmission of bar 4.
As shown in Fig. 2 the extension bar 4 of this example is connected by signal transmssion line with proximity transducer chip 3, extension bar 4 is
Bonding jumper, and it is two to extend the number of bar 4, proximity transducer chip 3 is capacitive proximity sensor, at proximity transducer core
Whether 3 by obtaining the capacitance signal of the extension transmission of bar 4 and through signal processing, finally judging human body near antenna body 2.
The schematic diagram of the proximity transducer chip 3 of this example is as shown in figure 3, specific operation principle is：Extension bar 4 passes through mould
Intend that signal transmission bundle of lines environmental capacitance value is continual is transferred to proximity transducer chip 3, the simulation in proximity transducer chip 3
The analogue signal of the capacitance is converted to digital signal by digital signal converter, then goes to comparator, and comparator counts this
Word signal is compared with pre-set reference signal, and this reference signal is the threshold value of proximity transducer chip 3, stores
In memory.When without human body close proximity to extension bar 4, the capacitance extended on bar 4 remains certain value CO,
The digital signal that CO is converted into cannot touch the thresholding of proximity transducer chip 3.When certain part of human body is near extension bar 4
When, CO changes, and when human body is more and more nearer, the change of CO is more and more violent, until its digital signal being converted into is touched
The threshold value set in advance in memorizer, is determined with human body close to predetermined distance, so as to proximity transducer chip 3 can be defeated
Go out specific digital signal to follow-up other functions chip (typically radio-frequency power control chip) to realize other functions
(for example reducing radio-frequency power to avoid problem of the absorption of human body than SAR).
