Embodiment
Below, describe embodiment of the present utility model in detail with reference to accompanying drawing.
Shown in Fig. 2 a and Fig. 2 b, be provided with rotary type speaker unit 300 according to the front upper of mobile communication terminal 200 of the present utility model.This rotary type speaker unit 300 can rotate, to select different pattern (ventional loudspeakers pattern or bone-conduction speaker pattern).
Referring to Fig. 3, this rotary type speaker unit 300 comprises housing 310 and ventional loudspeakers 320 and bone-conduction speaker 330.Housing 310 can be divided into procapsid 311 and back casing 312.The place ahead of described housing 310 (or on procapsid 311) forms opening, so that the propagation of the voice signal that ventional loudspeakers 320 is exported.During rotation, described housing 310 and ventional loudspeakers 320 and bone-conduction speaker 330 unitary rotation.For ease of rotating, the axial both sides of described housing 310 can be provided with projection (not shown), and mobile communication terminal 200 is provided with corresponding groove with it.Ventional loudspeakers 320 and bone-conduction speaker 330 are positioned at housing 310 inside, when generally conversing (ventional loudspeakers pattern), utilize the ventional loudspeakers output signal, and need utilize osteoacusis mode (bone-conduction speaker pattern) time, utilize the bone-conduction speaker output signal.Switching between two kinds of patterns realizes by roll-shell 310.To this, will be described hereinafter.
Referring to Fig. 4 (a), under the ventional loudspeakers pattern, ventional loudspeakers 320 face forward (diagram left) when the user listens to phone, are heard the sound that ventional loudspeakers 320 is sent.At this moment, just the same with general mobile communication terminal.Under this state, rotate counterclockwise housing 310, then bone-conduction speaker 330 face forward become the bone-conduction speaker pattern, shown in Fig. 4 (b).At this moment, people's face is attached to the ledge A of housing 310, then can hear the signal that bone-conduction speaker 330 sends, but other people can't hear but.Clockwise rotate housing 310 again, will get back to the ventional loudspeakers pattern.Fig. 4 middle shell protrudes in the mobile communication terminal back side, but be not limited thereto, housing can design the smaller and unlikely mobile communication terminal back side that protrudes in.
In order to discern residing pattern, with smooth output signal, mobile communication terminal 200 of the present utility model also is provided with monitoring portion.Monitoring portion monitors the rotational action of described housing, sends corresponding switching signal.This switching signal is sent to control part, by control part according to switching signal will be to be exported audio signal be sent to ventional loudspeakers or bone-conduction speaker.For example, the audio signal that control part will be to be exported under the ventional loudspeakers pattern is sent to ventional loudspeakers, this moment is if clockwise rotate the rotary type speaker unit, then monitoring portion sends first switching signal, when this first switching outputs to control part new number, control part will be to be exported audio signal be sent to bone-conduction speaker, thereby the conversion of implementation pattern.On the contrary, rotate counterclockwise if will be in the rotary type speaker unit of bone-conduction speaker pattern, then monitoring portion sends second switching signal, when this second switching outputs to control part new number, control part will be to be exported audio signal be sent to ventional loudspeakers, thereby the conversion of implementation pattern.
Described monitoring portion can adopt various transducers and switch, whether turns to the angle that the user can use and gets final product so long as can discern rotational action and can judge corresponding loud speaker.The formation of monitoring portion and control part belongs to known technology, does not repeat them here.
Among above-mentioned first embodiment, monitoring portion has adopted the transducer or the switch of the rotational action that can detect housing.But, also can adopt other forms, obtain second embodiment thus.
According to the mobile communication terminal of the utility model second embodiment, other structures are identical with first embodiment, and distinctive points is the formation of monitoring portion.That is, be provided with button in the position corresponding with bone-conduction speaker of outside, monitoring portion monitors the push action of this button, when button is pressed, send switching signal, control part receives this switching signal, and audio signal to be exported is sent to bone-conduction speaker.That is, among second embodiment, monitoring portion judges whether to carry out mode switch by detecting push action.Specifically, when needs switched to the bone-conduction speaker pattern, user's roll-shell made bone-conduction speaker one side forwards, again face is attached to housing, utilized face to push the button of outside, just can switch to the bone-conduction speaker pattern.When button left in face, button was released, and switched to the ventional loudspeakers pattern again.
The switching of pattern also can realize by special switching signal input part (button, button, function key, virtual push button etc.) is set.That is, special switching signal button is set on the mobile communication terminal main body, perhaps utilizes button on the keyboard or function key as the switching signal input part.Perhaps also can adopt virtual input part,, can come implementation pattern to switch by a certain zone of knocking on the touch-screen for example for touch controlled handset.Two switching signal input parts can be set, and one is used for switching to the ventional loudspeakers pattern, and one is used for switching to the bone-conduction speaker pattern.At this moment, directly monitor by cutting the switching signal of signal input part input, switch in the corresponding pattern by control part.Also a switching signal input part can only be set, be set at whenever to push and once just change pattern.
More than, the rotary type speaker unit is illustrated still, speaker unit of the present utility model also can be an on-rotary type.That is, housing can secure bond in mobile communication terminal.At this moment, make the housing at bone-conduction speaker place protrude in the mobile communication terminal surface, and the switching that button, monitoring portion and control part among above-mentioned second embodiment can implementation pattern is set.
And, above-mentioned switching signal input part and control part can be combined with above-mentioned on-rotary type speaker unit.At this moment, make the housing at bone-conduction speaker place protrude in the mobile communication terminal surface, come the switching of implementation pattern by the signal input of switching signal input part.
The utility model is not limited to the foregoing description, under the situation that does not break away from the utility model scope, can carry out various changes and modifications.
According to the utility model, because ventional loudspeakers and bone-conduction speaker are lumped together, rather than divide and be arranged, therefore saved the space has been set.Simultaneously, according to the utility model, can not use ventional loudspeakers when conversation to enter the problem of osteoacusis pattern mistakenly because of running into button because of carelessness.
