Embodiment
The utility model is described in further detail below by embodiment combination accompanying drawing.
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 close to 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 close to antenna body 2 according to the signal that extension bar 4 is transmitted.
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 the number of extension bar 4 is two, proximity transducer chip 3 is at capacitive proximity sensor, proximity transducer core
Whether 3, by obtaining the capacitance signal of the extension transmission of bar 4 and passing through signal transacting, finally judge human body close to 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 signal transmssion line the continual simulation being transferred in proximity transducer chip 3, proximity transducer chip 3 of environmental capacitance value
The analog signal of the capacitance is converted to data 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, storage
In memory.When no human body is close proximity to extension bar 4, the capacitance on extension bar 4 remains some value CO,
The data signal that CO is converted into can not touch the thresholding of proximity transducer chip 3.When some part of human body is close to extension bar 4
When, CO changes, and when human body is more and more nearer, CO change is more and more violent, until its data signal being converted into is touched
The threshold value set in advance into memory, is determined with human body close to predetermined distance, so that proximity transducer chip 3 can be defeated
Go out specific data signal to other follow-up functional chips (being typically radio-frequency power control chip) to realize other functions
(for example reducing radio-frequency power to avoid the problem of absorption of human body is than SAR).
Multiple extension bars 4 can be set according to actual needs, as shown in figure 4, the number of extension bar 4 can also be multiple,
