In order to better understand technique scheme, below in conjunction with Figure of description and concrete execution mode, technique scheme is described in detail.
Refer to Fig. 1, the embodiment of the present invention provides a kind of frequency adjusting method, and the method can be applied to electronic equipment, that is, in the method, the executive agent of each step can be electronic equipment.The flow process of the method is described below.
Step 101: determine that the attitude of electronic equipment is the second attitude by the first attitudes vibration; Wherein, when the first attitude, the operating frequency of the first antenna of electronic equipment is first frequency.
In the embodiment of the present invention, electronic equipment can have many attitude, for mobile phone, when this mobile phone be placed horizontally at desktop and display screen upward time, now can think a kind of attitude of this mobile phone, when the display screen of this mobile phone and desktop be miter angle degree be positioned over desktop time, now can think the another kind of attitude of this mobile phone, etc.Again for notebook computer, when being adjacent to placement between the upturning lid and notebook body (namely comprising the part of keyboard and processor) of this notebook computer, now can think a kind of attitude of this notebook computer, when upturning lid rotates extremely and is 90 degree between notebook body, now can think the another kind of attitude of this notebook computer, etc.
Wherein, the first attitude can be the current pose of general reference electronic equipment, and the second attitude can refer to another any attitude being different from the first attitude of electronic equipment.
In the embodiment of the present invention, multiple-input and multiple-output (the Multiple-InputMultiple-Output that electronic equipment can be comprised, MIMO) the first antenna regarded as by the main collection antenna in antenna system, or also the diversity antenna in mimo antenna system can be regarded as the first antenna, or also can be the antenna of other type, etc.Electronic equipment can be transmitted and/or Received signal strength by the first antenna, by transmit and/or Received signal strength to carry out transfer of data and/or communication.
Step 102: the value of the adjustable element in the tuning circuit corresponding with the first antenna is adjusted to the second value by the first value, to be adjusted to three frequency by the operating frequency of the first antenna by second frequency according to the second value; Wherein, the operating frequency of second frequency is the attitudes vibration of electronic equipment when being the second attitude the first antenna, first value is the value of adjustable element when electronic equipment is in the first attitude, and the 3rd frequency-splitting between frequency and predeterminated frequency is less than the frequency-splitting between second frequency and predeterminated frequency.
Wherein, predeterminated frequency can be the operating frequency of electronic equipment under any attitude or resonance frequency, also can be that operator is for obtaining optimum efficiency or other frequency values considered and set, in embodiments of the present invention, be preset value mainly with first frequency, but preset value is not limited to first frequency.
When detecting that the attitude of electronic equipment changes and changes to the second attitude, just can adjust the value of adjustable element, that is, in the embodiment of the present invention, can will detect that the attitude of electronic equipment changes as the trigger condition adjusted adjustable element.
Wherein, the tuning circuit corresponding with the first antenna, can be such as be exclusively used in the impedance matching network carrying out net mate between the first antenna and transmitter or receiver, a kind of possible tuning circuit as shown in Figure 2, the circuit be made up of variable capacitance C1, variable capacitance C2, inductance L 1 and inductance L 2 in rectangle frame in Fig. 2 is the tuning circuit of the first antenna, between visible tuning circuit and the first antenna, there is annexation, such as, can be connected by feeder line.
Wherein, adjustable element can comprise tunable capacitor and controllable impedance, and for Fig. 2, adjustable element can comprise variable capacitance C1 and variable capacitance C2, in fact the inductance L 1 in Fig. 2 and inductance L 2 also can be set to variable inductance, and are just illustrated with immutable inductance in Fig. 2.In specific implementation process, electronic equipment can by providing different magnitude of voltage to adjust the value of adjustable element for tuning circuit, and the value that can control multiple adjustable element changes simultaneously, or the value that also only can control an adjustable element changes.Continue for Fig. 2, such as, when electronic equipment provides the voltage of 3 volts for tuning circuit, the value of control C1 can become 30 skins and send out (PF), or the value of the control C1 simultaneously value that becomes 25PF and control C2 can become 18PF, etc.
User is in the process using electronic equipment, due to the change of holding mode or occupation mode, the attitude of electronic equipment generally can be caused to change, mobile phone is picked up from desktop and is received calls by such as user, so, generally can think because the operation of user and then the attitude of electronic equipment that causes change, and because human body itself can affect the radiation of the first antenna, so electronic equipment can be regarded as residing media environment and there occurs change when attitude changes, according to the Computing Principle of the operating frequency of the first antenna, so the operating frequency of the first antenna now generally can be caused to change.
Such as, when the first attitude, the operating frequency of the first antenna is first frequency, and when electronic equipment is the second attitude by the first attitudes vibration, the operating frequency of the first antenna is just changed in order to second frequency by first frequency, and then cause the operating frequency of electronic equipment to there occurs skew, skew due to operating frequency may cause short interruption or the instability of communication or transfer of data, the normal use of electronic equipment will be affected like this, and, first antenna also may not as good as the performance of carrying out work with first frequency with the performance that the operating frequency (i.e. second frequency) after skew works, that is, the frequency shift (FS) caused due to attitude also may cause the hydraulic performance decline of antenna.
So, in order to reduce the frequency shift (FS) because attitudes vibration causes as far as possible, after detecting that electronic equipment is the second attitude by the first attitudes vibration, just the value of adjustable element can be adjusted to reduce frequency shift (FS) as far as possible, such as can by the value of adjustable element (C1 in such as Fig. 2) be adjusted to the second value by the first value during the first attitude, the operating frequency of the first antenna is adjusted to the 3rd frequency according to the second value, namely compensated because environmental capacitance changes the frequency deviation caused by the change of the capacitance in tuning circuit, frequency-splitting between second frequency and first frequency is less than to make the 3rd frequency-splitting between frequency and first frequency, frequency shift (FS) can be reduced so as far as possible, this is take first frequency as the situation of predeterminated frequency.
Optionally, 3rd frequency-splitting between frequency and first frequency is less than or equal to preset frequency threshold value, or, optionally, 3rd frequency values is equal with the value of first frequency, that is, can by the adjustment of the value of adjustable element, 3rd frequency is adjusted to as far as possible close with first frequency, or it is directly equal with first frequency, even if the attitude of electronic equipment there occurs change like this, also the operating frequency of the first antenna can be compensated to the operating frequency before as attitudes vibration as far as possible, the stability of the first Antenna Operation can be ensured so as far as possible.This is take first frequency as the situation of predeterminated frequency, also the effect that predeterminated frequency desirably reaches can be set as other frequencies.
Wherein, preset frequency threshold value can be determined according to factors such as the actual demands of the ardware feature of the performance of the first antenna, electronic equipment and user, and the present invention does not do concrete restriction.
Optionally, before the value of the adjustable element in the tuning circuit corresponding with the first antenna is adjusted to the second value by the first value, also comprise: determine that the frequency-splitting between second frequency and first frequency is greater than preset frequency difference.
In specific implementation process, just adjustment can be compensated to the operating frequency of the first antenna when determining that the frequency-splitting between second frequency and first frequency is greater than preset frequency difference, that is, due to the change of electronic equipment attitude, can allow the operating frequency of the first antenna that some skews occur, but in order to not affect the performance of the first antenna as far as possible, what preset frequency difference can be arranged is as far as possible little, such as 3HZ, 5HZ, etc., can avoid like this adjusting too frequently, to reduce the processing load of electronic equipment as far as possible.This is take first frequency as the situation of predeterminated frequency, also the effect that predeterminated frequency desirably reaches can be set as other frequencies.
In specific implementation process, be determine the 3rd frequency according to the second value correspondence of adjustable element, so, how to determine the adjustment amount of adjustable element, that is, the 3rd frequency be obtained, how the second corresponding value should be determined, the embodiment of the present invention provides following two kinds to determine mode.
First kind of way:
Optionally, before the value of the adjustable element in the tuning circuit corresponding with the first antenna is adjusted to the second value by the first value, also comprises: when the attitudes vibration of electronic equipment is the second attitude, determine the environmental capacitance value of the first antenna, again according to the environmental capacitance value determined, determine the second value.
Specifically, according to the frequency-splitting of second frequency and first frequency, namely according to the frequency offset determination environmental capacitance value of the first antenna, and then the second value can be determined again.
It is because environmental capacitance value changes largely that operating frequency due to the first antenna changes, so determine the second value by environmental capacitance value and then determine the 3rd frequency, can in the accuracy ensureing largely to adjust, and the specific aim of adjustment is also stronger, obviously, effect is better in adjustment change.
Optionally, when the attitudes vibration of electronic equipment is the second attitude, determine the environmental capacitance value of the first antenna, comprise: when the attitudes vibration of electronic equipment is the second attitude, determine that the first distance between electronic equipment and desired body area is less than preset distance, again according to the first distance, determine environmental capacitance value.
Such as can by the first distance between the range sensor determination electronic equipment in electronic equipment and desired body area, can by imageing sensor determination desired body area, wherein, desired body area is such as the head of user, cheek or palm, etc.Distance between electronic equipment and desired body area is nearer, shows electronic equipment more close to human body, and now human body is also larger for the impact of the radiation of the first antenna, and the impact so for the first antenna performance is also larger.
In practice, what preset distance can be arranged is as far as possible little, such as 2 centimetres, when determining that the distance between electronic equipment and human body is less than preset distance, such as, when user's handling mobile phone receives calls, can think that the now impact of user on the performance of the first antenna is larger, now just can determine environmental capacitance value according to the first distance.Such as can determine according to the mapping table between the distance preset and environmental capacitance value, or can calculate according to the computing formula preset and determine, etc., and mapping table or computing formula can be user's experimentally data or arrange based on experience value in advance.
The second way:
Optionally, before the value of the adjustable element in the tuning circuit corresponding with the first antenna is adjusted to the second value by the first value, also comprises: the active force determining to act on the first antenna, according to the active force determined, determine the second value.
First antenna is generally the ad-hoc location be arranged in electronic equipment, generally can not change after setting again.When the attitude of electronic equipment changes, generally also can be subject to certain applied external force, such as when the mode of user's handling electronic equipment changes, mobile phone lies in palm and watches film or grip mobile phone when receiving calls by such as user, because the change of holding mode is so result also in the change of curable grip, so the applied external force that is subject to of electronic equipment is also just different, or when the use attitude of electronic equipment changes, the upturning lid that such as user opens notebook computer carries out work or upturning lid is detained to close notebook computer by user, also different owing to upturning lid turning over and detains the pressure caused for the antenna in notebook computer, etc..
So, in the embodiment of the present invention, the size of applied external force suffered by the first antenna can determine the second value, the reason had an impact with the operating frequency considered for the first antenna as far as possible.In addition, similar with first kind of way, the mode such as predetermined mapping table or predetermined computing formula also can be adopted to determine the second value according to the size of active force, just repeat no more herein.
Optionally, the frequency adjusting method in the embodiment of the present invention also comprises:
If the value of first frequency is different from the value of the resonance frequency of the first antenna, then the value of adjustable element is adjusted to the 3rd value by the first value, the operating frequency of the first antenna is adjusted to resonance frequency by institute's second frequency according to the 3rd value.
That is, if determine that the operating frequency of electronic equipment before attitudes vibration is not resonance frequency, then show that the performance of the first antenna when electronic equipment is in the first attitude is not optimum, and after attitudes vibration being detected, just directly the operating frequency of the first antenna can be adjusted to resonance frequency, such electronic equipment is after attitudes vibration, namely resonance frequency can be adopted to carry out work, to reach optimum antenna performance, also can strengthen the meaning of frequency adjustment, promote regulated efficiency.
In the application, when electronic equipment is in the first attitude, the operating frequency of the first antenna in electronic equipment is first frequency, and electronic equipment can be the second attitude detecting by the first attitudes vibration, and then the value of the adjustable element in the tuning circuit corresponding with the first antenna can be adjusted to the second value by the first value, second frequency during the operating frequency of the first antenna has just been changed to the second attitude by electronic equipment attitude according to the second value is adjusted to the 3rd frequency, and make the 3rd frequency-splitting between frequency and first frequency be less than frequency-splitting between second frequency and first frequency, to reduce the frequency shift (FS) that electronic equipment produces when attitudes vibration, ensure the stability of operating frequency of antenna as far as possible.
That is, when the attitude of electronic equipment changes, can be compensated with the frequency shift (FS) produced due to attitudes vibration the first antenna by the value of adjustable element in adjustment tuning circuit, because the attitudes vibration of electronic equipment is generally because user changes in the process using electronic equipment, so be the equal of compensate by the adjustable element in adjustment tuning circuit the frequency shift (FS) caused because environmental capacitance changes, thus make the operating frequency of the first antenna keep stable, and then promote the performance of antenna as far as possible.
