In order to make technical problem solved by the invention, technical scheme and beneficial effect clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
The invention provides a kind of PTT key asembly of mobile terminal of embodiment, as shown in figures 1 and 3, described PTT key asembly comprises switch element 1, can the keying body 2 of trigger switch element 1 conducting, optical transmitting set 3, optical receiver 4, is arranged on the container cavity 21 in keying body 2 and is arranged on bottom keying body 2 and can supports the elastic component of described keying body 2, described container cavity 21 opening is towards keying body 2 upper surface, and described optical transmitting set 3 and optical receiver 4 are arranged in container cavity 21;
Optical transmitting set 3, for being pressed when keying body, during switch element 1 conducting, exports the light signal preset;
Optical receiver 4, for being capped when the opening of container cavity in keying body 2, receives the light signal of optical transmitting set 3, and according to described light signal, exports and keep right of speech signal.
In the present embodiment, described elastic component is spring 5.
As can be seen from such scheme, when user is by pressing keys body 2, just can trigger switch element 1 conducting, get calling right of speech, when switch element 1 conducting, optical transmitting set 3 exports the light signal preset, and when as long as the opening of container cavity 21 is capped, optical receiver 4 just can receive the light signal of optical transmitting set 3, and according to described light signal, export and keep right of speech signal, make user not need to press PTT key at full tilt during calling speech always, as long as the opening of container cavity 21 is covered, just can keep calling out right of speech, therefore can Consumer's Experience be improved, user-friendly.
In concrete enforcement, described PTT key asembly also comprises the lid (not shown on figure) that can cover container cavity 21 opening part, and described lid can be rotationally connected with described keying body 2, is convenient to the opening that lid covers described container cavity 21.When user is by pressing keys body 2, after trigger switch element 1 conducting, container cavity 21 opening part can be covered by lid, make optical receiver 4 just can receive the light signal of optical transmitting set 3, and according to described light signal, export and keep right of speech signal, so in the process keeping calling right of speech, just do not need the finger of user to be placed on container cavity 21 opening part always, namely user also does not just need to press PTT key during calling speech always, also can keep calling out right of speech, thus can the use of convenient user.
In concrete enforcement, described container cavity 21 comprises the first groove for holding optical transmitting set 3 and the second groove for holding optical receiver 4, described first groove is communicated with the second groove, the bottom of described first groove is provided with the first location hole 22 of fixed light reflector 3, and the bottom of described second groove is provided with the second location hole 23 of fixed light receiver.In the present embodiment, the longitudinal cross-section of described first groove is horn-like, the longitudinal cross-section of described second groove is horn-like, the irradiated area of the light that optical transmitting set 3 exports can be expanded, when user being pointed be not placed on directly over container cavity 21 opening, optical receiver 4 also can receive the light that optical transmitting set 3 exports.
In concrete enforcement, described container cavity 21 also comprises the compartment part 24 be arranged between described first groove and the second groove, can ensure that light from optical transmitting set 3 direct projection to optical receiver 4, thus can not there will not be misoperation when the opening of container cavity 21 is not capped.Described compartment part 24 is specifically as follows dividing plate, and in the present embodiment, described compartment part 24, in wedge shape, is wedge shape part.
In concrete enforcement, described optical transmitting set is specially infrared light generator, and optical receiver is specially infrared light receiver.
In concrete enforcement, in order to realize, the present invention also provides a kind of mobile terminal of embodiment, as Fig. 2, shown in Fig. 3 and Fig. 4, described mobile terminal comprises terminal body 6, controller 7, also comprise the PTT key asembly of above-described embodiment, described terminal body 6 is connected by described elastic component with keying body 2, described controller 7 respectively with optical transmitting set 3, optical receiver 4 and switch element 1 are electrically connected, for when switch element 1 conducting, control optical transmitting set 3 and export the light signal preset, and obtain calling right of speech, when receiving the maintenance right of speech signal of optical receiver, keep calling right of speech.
As can be seen from such scheme, when user is by pressing keys body 2, just can trigger switch element 1 conducting, get calling right of speech, when switch element 1 conducting, optical transmitting set 3 exports the light signal preset, and when as long as the opening of container cavity 21 is capped, optical receiver 4 just can receive the light signal of optical transmitting set 3, and according to described light signal, exports and keep right of speech signal, make user not need to press PTT key at full tilt during calling speech always, as long as the opening of container cavity 21 is covered, just can keep calling out right of speech, user-friendly.
In concrete enforcement, described switch element 1 is specially key switch, and described key switch is arranged on described terminal body 6, and can support with the bottom of described keying body 2.
In concrete enforcement, as shown in Figure 4, when optical transmitting set 3 receives the control signal of controller 7, optical transmitting set 3 sends the light of specific wavelength and certain strength, and optical receiver 4 can change its resistive properties (this is the build-in attribute of optical receiver) when being subject to the light of fixed frequency, and constantly reduce along with the increase resistance of light, when resistance is reduced to certain threshold value, output low level signal or high level signal will namely keep right of speech signal, right of speech signal is kept when controller 7 receives, just can judge have object to cover on PTT button, thus make mobile terminal keep PTT to call out right of speech.In the present embodiment, optical transmitting set 3 exports Infrared, and optical receiver 4 is when receiving Infrared, just meeting output low level signal or high level signal, so just can to avoid under the irradiation of optical receiver 4 at natural daylight also outputs level signals, and avoid the situation occurring misoperation.
Be understandable that, except adopting infrared transmitter and corresponding infrared light receiver, also can adopt other visible light-emitting devices and receiving device, not repeating.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
