[0078] 如图3所示,所述传动机构还包括:第一齿轮4、第二齿轮5和齿条6,第一齿轮4固定在第一转轴I上,显示端200与第一转轴I固定连接,显示端200转动时带动第一转轴I和第二齿轮4转动;第二齿轮5固定在第二转轴3上,扬声器本体2与第二转轴3固定连接;齿条6具有分别与第一齿轮4和第二齿轮5相嗤合的第一齿部7和第二齿部8,第一齿轮4随显示端200转动时推动齿条6朝向第二齿轮5的方向移动,由于齿条6的第二齿部8与第二齿轮5相啮合,因此齿条6的移动能够带动第二齿轮5及扬声器本体2转动。 [0078] As shown in FIG. 3, the drive mechanism further comprises: a first gear 4, the second gear 6 and the rack 5, the first gear 4 is fixed to the first shaft I, the first rotary shaft 200 and the display I fixedly connected to the first display drive shaft 4 is rotated I and the second gear 200 is rotated end; a second gear 5 is fixed to the second shaft 3, a speaker body 2 and a second rotary shaft 3 is fixedly connected; and the second rack 6 having respectively a gear portion 4 and the first tooth and the second tooth portion 7 of the second gear 5 engaged with laugh 8, the first driven gear 4 with the rack 6 displays the moving direction toward the second gear 5 is rotated end 200, since the rack 8 and the second tooth portion 5 engages the second gear 6, and thus movement of the rack 6 can be driven by rotation of the second gear 2 and loudspeaker 5 body. 由于扬声器本体2无需像显示端200 —样,工作状态至少旋转至90度(一般会大于90度)。 Since the speaker body 2 without the image display end 200-- like, rotating the operating state of at least 90 degrees (typically greater than 90 degrees). 而扬声器本体2只需转动一定角度使其上的出音孔9露出即可(一般无需大于90度)。 The speaker main body 2 is rotated a certain angle so that only the sound hole 9 is exposed to (typically greater than 90 degrees without). 因此,当显示端200转动时,只需通过齿条6带动扬声器本体2转动至预定角度(例如60度)即可,当显示端200继续转动时不会再带动扬声器本体2转动。 Thus, when the rotating terminal display 200, the speaker simply driven by a rack 6 of the body 2 is rotated to a predetermined angle (e.g. 60 degrees) can, when the display terminal 200 will not continue to rotate the speaker main body 2 rotatably driven. 齿条6上还具有用于控制开关10启闭的按压部11。 The rack 6 further has a pressing portion 10 for controlling the opening and closing of the switch 11. 开关10的设置位置固定不动,按压部11随齿条6的移动而移动,按压部11在移动时与开关10触碰或分离(触碰时扬声器本体2禁声,分离时扬声器本体2发声),从而实现开关10的启闭。 Position switch 10 is provided stationary, moving the pressing portion 11 is moved with the rack 6, the speaker main body 2 is pressed gag portion 11 and the separation switch 10 or the touch (touch is moving, the main body 2 is separated from the speaker sound ), enabling opening and closing of the switch 10.

[0079] 为了实现显示端200仅带动扬声器本体2转动至预定角度后不再继续跟随显示端200的翻转而翻转,就应该在显示端200继续翻转时,第一齿轮4不再驱动齿轮6移动或者第二齿轮5不再与齿条6相啮合。 [0079] In order to realize the display drive terminal 200 only after the speaker body 2 is rotated a predetermined angle does not continue to flip display 200 follows the end of the flip, flip it should proceed, the first gear 4 is no longer driven gear 6 is moved in the display terminal 200 5 or the second gear 6 is no longer meshed with the rack. 本实施例中采用的是当扬声器本体2转动至预定角度后,第一齿轮4脱离与齿条的啮合,第一齿轮4继续转动时齿条6保持不动。 The present embodiment is employed when the speaker main body 2 is rotated to a predetermined angle, a first gear meshing with the rack 4 out of 4 continues to rotate the first gear rack 6 remains stationary. 如图3所示,并同时结合图4、图5和图6,具体的结构为:第一齿部7和第二齿部8分别位于齿条6的靠近两端部;第一齿轮4和第一齿部7的相啮合段短于第二齿轮5和第二齿部8的相啮合段。 3, and also in conjunction with Figures 4, 5 and 6, a specific configuration of: a first tooth and a second tooth portion 7 are located close to both end portions 8 of the rack 6; and a first gear 4 section engages the first tooth portion 7 is shorter than the second gear 5 and the second tooth segment engaged portion 8. 本实施例中的第一齿轮4的轮面上没有完全布满齿,而是仅设置了部分齿,当第一齿轮4转动一定角度后,即使继续转动也不会带动齿条6继续移动。 A first gear wheel in the present embodiment the surface is not completely covered with the teeth 4, but only a partial set of teeth, when the first gear 4 is rotated a certain angle, it will not continue to rotate even if the drive continues to move the rack 6. 同样的,第二齿轮5也仅设置部分齿,大部分轮面是光滑的,但第二齿轮5上的齿比第一齿轮4上的齿多,且第二齿部8比第一齿部7长。 Similarly, the second gear 5 is only part of the tooth is provided, most of the tread is smooth, but the gear ratio of the second gear 5 on the plurality of teeth on the first gear 4, and the second tooth portion than the first tooth portion 8 7 long.

[0080] 实际上,第一齿部7的齿数与第一齿轮4上的齿数可以相等也可以不相等,同样的,第二齿部8的齿数与第二齿轮5上的齿数可以相等也可以不相等,只要保证当显示端200转动至大于扬声器本体2的所述预定角度时,显示端200的转动不会再带动扬声器本体2继续跟随转动即可。 [0080] In fact, the number of teeth on the number of teeth of the first gear 4 of the first tooth portion 7 may be equal or may not be equal, the same number of teeth on the second portion 8 and the number of teeth of the second gear 5 may be equal We are not equal, as long as when the display 200 is rotated to the end is larger than said predetermined angle speaker body 2, the display will not be driven by rotation of the end 200 of the speaker body 2 to continue to follow the rotation. 如图3所示,本实施例中第一齿部7的齿数与第一齿轮4上的齿数相等,而第二齿部8的齿数多于第二齿轮8上的齿数;且第一齿部7的齿数少于第二齿部8的齿数。 3, the present embodiment 4, the number of teeth on the first gear teeth of the first tooth portion 7 is equal embodiment, the number of teeth and the second tooth portion 8 is larger than the number of teeth on the second gear 8; and a first tooth portion 7 teeth less than the number of teeth of the second tooth portion 8.

[0081] 当显示端200处于工作角度时,即显示端200翻转至与系统端300呈大于90度的角度时,如果使用者只想关闭扬声器,可以只需向下按压使扬声器本体2翻转而处于禁声状态即可。 [0081] When the display terminal 200 in the working angle, i.e., the display was flipped end 200 to end 300 to the system when an angle greater than 90 degrees, if a user want to turn off the speaker, the speaker can simply pressed down and turned over the main body 2 in the state to gag. 因此,本发明的翻转扬声器还包括:止挡件12、推抵部13和弹性复位元件14,弹性复位元件14设置于在第二转轴3上,当扬声器本体2由所述预定角度反向转动时通过第二齿轮5将推动齿条6朝向第一齿轮I的方向移动,同时弹性复位元件14积蓄扭力。 Accordingly, the present invention further flip speaker comprising: a stopper 12, the elastic pushing portion 13 and the reset member 14, the elastic return element 14 is disposed on the second shaft 3, when the speaker main body 2 by the reverse rotation of the predetermined angle 5 through the second gear when the pushing direction of the rack 6 moves toward the first gear I, the reset member 14 while the elastic torsion accumulated. 此过程中,止挡件12用于当齿条6运动至其上的按压部11与开关10触碰时,阻挡齿条6的继续运动,使齿条6保持在固定位置,同时也保证了第二齿轮5以及扬声器本体2的位置保持不动。 In this process, when the stopper 12 for the movement of the rack 6 to which the pressing portion 11 on the touch when the switch 10, blocking further movement of the rack 6, the rack 6 in a fixed position, but also to ensure 5 and a second gear position of the speaker body 2 remains stationary. 由于按压部11与开关10触碰,使扬声器本体2处于禁声状态,实现了在显示端200处于工作角度时,能独立控制扬声器本体2的关闭。 Since the pressing portion 11 and the touch switch 10, the speaker main body 2 in a state gag realized when the display 200 is operating angle end, independently controls the speaker main body 2 is closed. 推抵部13设置于第一齿轮4上,当显示端200由工作角度关闭至第一齿轮4与齿条6处于啮合状态或即将啮合状态时,推抵部13推抵止挡件12,使止挡件12解除对齿条6的止挡,在弹性复位元件14的扭力作用下,第二齿轮5正向转动,而齿条6则在第二齿轮5的带动下朝向第二齿轮5的方向移动,此时,本发明的整个翻转扬声器回复至初始状态(所谓初始状态,是指显示端200和扬声器本体2均处于O度的状态,按压部11与开关触碰,第一齿轮4与第一齿部7嗤合,第二齿轮5与第二齿部8啮合)。 Pushing portion 13 is provided on the first gear 4, when the display 200 is closed by the end of the working angle of the first gear 4 to 6 in engagement with the rack or about the engagement state, the pushing portion 13 pushes against the stopper 12, so that the stopper member 12 releases the stop of the rack 6, in the reset action of the elastic torsion element 14, the forward rotation of the second gear 5, the gear rack 6 5 toward the second driven gear 5 of a second direction, in this case, the entire inverted speaker of the present invention returns to the initial state (the so-called initial state, the terminal 200 refers to the display and the speaker main body 2 is in a state of O, the pressing portion 11 and the touch switch, and a first gear 4 the first engagement tooth laugh portion 7, the second gear 5 engages with the second tooth portion 8).

[0097] 如图11所示,当显示端200处于O度时,扬声器本体2位于系统端300的容置槽内,按压部11与开关10接触,使扬声器本体2处于禁声状态,第一齿轮4右侧(所谓右侧,是指图中的右侧,以下同)的齿与第一齿部7上的右侧的齿处于啮合状态;第二齿轮5右侧的齿与第二齿部8上的右侧的齿处于啮合状态;而左侧均处于未啮合状态,随着显示端200的转动,带动第一齿轮4转动并驱动齿条6朝向第二齿轮6 (或扬声器本体2)的方向移动,齿条6在移动的过程中带动第二齿轮5转动,使扬声器本体2转动随之转动,扬声器本体2上的出音孔9露出,并且齿条6上的按压部11脱离开关10,扬声器本体2由禁声状态切换至允许发声状态。 [0097] As shown in FIG. 11, when the display terminal 200 is O degrees, the speaker system located in the body 2 side receiving groove, the pressing portion 300 of the contact 11 and the switch 10, the speaker main body 2 in a state gag, first the right gear 4 (the so-called right, right in the figure refers to the same hereinafter) on the right side of the teeth 7 of the teeth and the first tooth portion is in the engaged state; a second right teeth 5 and the second gear teeth on the right side of the teeth 8 in engagement; and are left in a non-engaged state, the rotation of the display terminal 200, rotation of the first driven gear 4 and the rack drive gear 6 6 towards the second (or speaker body 2 ) in the moving direction, the second driven gear 6 of the rack 5 during the movement of rotation of the rotatable body 2 rotates with loudspeaker, the sound hole 9 on the speaker body 2 is exposed, and the pressing portion departing from the upper rack 611 switch 10, the speaker main body 2 is switched to the allowed state by the gag sounding state. 扬声器本体2最后转动至如图12所示的状态。 Last speaker body 2 is rotated to the state shown in FIG. 12. 在该转动过程中扭簧释放积蓄的扭力(如何积蓄扭力将在下面介绍)。 In this rotation the torsion spring to release accumulated torsion (torsion how accumulated will be described below).

[0098] 当扬声器本体2转动至预定角度60度时,由于第一齿轮4上仅设置局部齿,该齿已脱离与齿条6的啮合,继续转动显示端200时将不再驱动齿条6移动,使得第二齿轮5也不再被驱动,扬声器本体2便保持在预定角度不动。 [0098] When the speaker main body 2 is rotated to a predetermined angle of 60 degrees, since the teeth only partially on the first gear 4, which has been out of engagement with the rack teeth 6, continued rotation of the display 200 is no longer driven when the end of the rack 6 moved such that the second gear 5 is no longer driven, the speaker main body 2 is maintained in a predetermined fixed angle. 如图13所示,显示端200可转动至需要的任何工作角度(如150度)。 As shown in FIG. 13, the end 200 may be rotated to any desired angle of the work (e.g., 150 degrees).

[0099] 在上述状态下,如果关闭显示端200,当显示端200关闭至60度时,第一齿轮4上的齿又与第一齿部7相嗤合,并带动齿条6和第二齿轮5动作,实现第二齿轮5和扬声器本体2的转动,实现扬声器本体2的关闭。 [0099] In the above state, if the terminal 200 turns off the display, when the display terminal 60 to 200 degrees off, the teeth on the first gear 4 and 7 and the first tooth portion engaged with laugh, and drives the rack 6 and the second 5 gear operation, to achieve the second gear 5, and the speaker main body 2 is rotated to achieve speaker body 2 is closed. 在此过程中,扭簧积蓄扭力。 In this process, the savings torsion torque.

[0100] 当显示端200处于工作角度,而使用者只想关闭扬声器,如图14和图15所示,只需按压并翻转扬声器本体2,使扬声器本体2处于小于O度的某一角度,例如负5度(此过程,扭簧积蓄扭力),第二齿轮5在扬声器本体2的带动下反向转动并驱动齿条6向第一齿轮4的方向移动,齿条6上的按压部11触碰开关10,同时止挡件卡入齿条6的止挡槽17内,挡住齿条6,使其不能继续移动,从而实现了显示端200处于工作角度时,能够单独关闭扬声器本体2,使其处于禁声状态。 [0100] When the display 200 is operating angle end, and the user just off the speaker, as shown in FIGS. 14 and 15, simply pressing the speaker body 2 and turned over, so that the speaker main body 2 at a certain angle of less than O degrees, for example, minus 5 degrees (this process, the torsion spring savings torque), the second drive gear 5 and reverse rotation of the rack 6 is moved in the direction of the first gear 4 is driven by the speaker body 2, the pressing portion 11 on the rack 6 tact switch 10, while the stopper member snaps into the groove 6 of the rack stopper 17, blocking the rack 6, it can not move, when in order to achieve the operating angle, speaker body 2 can be closed separately display terminal 200, it is in the state gag.

[0101] 在图14所示的状态下,如果使用者想关闭显示端200,在最初的转动过程中,由于第一齿轮4与第一齿部7不啮合,显示端200的转动不会引起齿条6的任何动作,如图16和图17所示,当显示端200转动至5度时,第一齿轮4上的推抵部13转动至止挡片15处,并随着第一齿轮4的转动推抵止挡片15,使其脱离止挡槽17,解除对齿条6的止挡。 [0101] In the state shown in FIG. 14, if the end user wants to turn off the display 200, the initial rotation, since the first gear 4 is not engaged with the first gear section 7, the display 200 does not cause rotation of the end 6 any action of the rack, as shown in FIG. 16 and FIG. 17, when the display terminal 200 is rotated to 5 degrees, the pushing portion 4 of the first gear 13 is rotated to the stopper piece 15, and with the first gear 4, the rotation stopper piece 15 pushing, away from the stopper grooves 17, the stopper release of the rack 6. 扭簧释放扭力,在扭簧的扭力作用下,第二齿轮8反向转动,齿条6则在第二齿轮8的带动下朝向第二齿轮8的方向运动,当运动到扬声器本体2处于O度时,齿条6被第一齿轮4上的齿挡住并限位而恢复至图11所示的初始状态。 Release the torsion spring torsion, under the action of the torsion of the torsion spring, the second gear 8 to rotate in reverse direction toward the rack 6 of the second driven gear 8 of the second gear 8, when the body 2 is moved to the speaker O when the degree of the rack teeth 6 is blocked by the stopper and the first gear 4 is restored to the initial state shown in FIG. 11.
