当发声装置1000处于第一状态时,第一腔体110为独立的封闭腔体,第二腔体210为独立的封闭腔体。第一腔体110与第二腔体210相互隔绝。第一腔体110形成第一电声单元120的后腔,第二腔体210形成第二电声单元220的后腔。第一电声单元120和第二电声单元220可以接收相同的音频信号,也可以接收不同的音频信号。第一电声单元120和第二电声单元220可分别作为两个独立的扬声器发声。第一出音孔131和第二出音孔231分别出射第一电声单元120的声音和第二电声单元220的声音。可以 理解的是,第一腔体110和第二腔体210并非绝对的封闭腔体,第一腔体110的封闭形式是为了防止第一电声单元120声短路,第二腔体210的封闭形式是为了防止第二电声单元220声短路。
当发声装置1000处于第二状态时,第一腔体110与第二腔体210连通形成第三腔体。第三腔体为封闭的腔体。第三腔体构成第一电声单元120和第二电声单元220共同的后腔。第一电声单元120所接收的音频信号与第二电声单元220所接收的音频反相设置。也就是说,当第一电声单元120接收一个音频信号时,第一振膜121的正面朝第三腔体内运动,第二电声单元220此时接收一个反相的音频信号,第二振膜221的反面朝第三腔体内运动,从而形成第一振膜121向第三腔体推动气流,第二振膜221正好相反地朝第三腔体内拉动气流。当第一电声单元120接收到另一个音频信号时,第一振膜121的正面朝第三腔体外运动,第二电声单元220此时接收一个反相的音频信号,第二振膜221的反面朝第三腔体外运动,从而形成第一振膜121向第三腔体外拉动气流,第二振膜221正好相反地朝第三腔体外推动气流。可以理解的是,第三腔体并非绝对的封闭腔体,第三腔体的封闭形式是为了防止第一电声单元120和第二电声单元220声短路。
可以理解的是,当发声装置1000处于第二状态时,第一电声单元120和第二电声单元220可形成一正一反地声音投射,第一电声单元120和第二电声单元220,以及第三腔体构成推挽式扬声器结构,第一振膜121和第二振膜221朝第三腔体内或外的运动方向是一致地,第一电声单元120和第二电声单元220可以消除掉第三腔体内部的反作用力,同时也可以大大减少偶次(特别是二次)谐波失真。相较于单个电声单元独立发声,第一电声单元120和第二电声单元220结合第三腔体形成推挽式扬声器结构,可以提供更高质量的纯净声音输出。
在常规的技术方案中,一些电子设备也会设置多个扬声器,并对应设置多个腔体,然而多个腔体相互独立,使得多个扬声器均是独立发声,并不能实现推挽式发声结构,导致整体存在谐波失真,降低声音输出质量。本申请的发声装置1000利用第一腔体110与第二腔体210可连通形成第三腔体,而第一电声单元120朝第三腔体内投射声音,第二电声单元220朝第三腔体外投射声音,且第一电声单元120的振动波与第二电声单元220的振动波反相设置,从而第一电声单元120的发声和第二电声单元220的发声在第三腔体内可抵消反作用力,从而可以减少谐波失真,进而提高声音输出质量。
可选的,第一电声单元120靠近第一腔体110内固定于第一壳体130,第二电声单元220靠近第二腔体210外固定于第二壳体230。当然,也可以是第一电声单元120靠近第一腔体110外固定于第一壳体130,第二电声单元220靠近第二腔体210内固定于第二壳体230。也可以是第一电声单元120和第二电声单元220分别靠近第一腔体110内和第二腔体210内。也可以是第一电声单元120和第二电声单元220分别靠近第一腔体110外和第二腔体210外。本申请的实施方式中,对第一电声单元120在第一主体100的位置并局限本申请实施方式所描述的方式,对第二电声单元220在第二主体200的位置也并不局限本申请实施方式所描述的方式。

可以理解的是,本申请的发声装置1000对第一主体100设置第一腔体110的数量,以及设置第一电声单元120的数量并不限定,对第二主体200设置第二腔体210的数量,以及设置第二电声单元220的数量并不限定。换言之,第一腔体110及第一电声单元120的数量可以均为多个,多个第一腔体110相互间隔设置,多个第一电声单元120对应多个第一腔体110设置,第二腔体210及第二电声单元220的数量可以均为多个,多个第二腔体210相互间隔设置,多个第二电声单元220对应多个第二腔体210设置。当发声装置1000处于第二状态时,第一腔体110与第二腔体210以一个对多个,或多个对一个,或多个对多个,或一一对应的方式连通。

本申请的第一实施例中,第一活动板150的活动力矩和第二活动板250的活动力矩来自第一主体100和第二主体200的翻转力矩,也就是说第一活动板150相对第一壳体130滑动,与第一壳体130相对第二壳体230转动是同步的,第二活动板250相对第二壳体230滑动,与第二壳体230相对第一壳体130转动是同步的。
当发声装置1000处于第一状态时,第一壳体130相对第二壳体230展开,利用传动机构400的传动作用力,同步带动第一活动板150和第二活动板250运动至分别封堵第一通孔140和第二通孔240位置,实现第一腔体110与第二腔体210隔绝,即第一电声单元120和第二电声单元220相互独立发声。当发声装置1000处于第二状态时,第一壳体130相对第二壳体230叠合,利用传动机构400的传动作用力,同步带动第一活动板150和第二活动板250运动至分别开启第一通孔140和第二通孔240位置,实现第一腔体110与第二腔体210连通,即第一电声单元120和第二电声单元220共同构建成推挽式扬声器结构。也就是说,第一腔体110与第二腔体210的断开或连通,以第一主体100与第二主体200相互翻转的机械运动方式所控制。
当然,在其他实施例中,也可以是通过电子信号控制第一腔体110与第二腔体210断开或连通,也就是第一活动板150相对第一壳体130的运动与第一壳体130相对第二壳体230的运动独立分开,第二活动板250相对第二壳体230的运动状态与第二壳体230相对第一壳体130的有的运动状态独立分开。例如,如图16所示,基于第一实施例的一种改进实施例中,第一主体100设有驱动第一驱动齿轮440转动的第一电机180,第一电机180可接收电子驱动信号。电子驱动信号可来自传感器、显示屏300的触控模块、处理器、开关按键等器件。第一电机180驱动第一驱动齿轮440转动,第一驱动齿轮440带动第一齿条430滑动,进而驱动第一伸缩杆160伸缩,以推拉第一活动板150开启或封堵第一通孔140。可以理解的是,当第二主体200设有第二伸缩杆270时,第二主体200设有驱动第二驱动齿轮441转动的第二电机280,第二电机280可接收电子驱动信号。电子驱动信号可来自传感器、显示屏的触控模块、处理器、开关按键等器件。第二电机280驱动第二驱动齿轮441转动,第二驱动齿轮441带动第二齿条431滑动,进而驱动第二伸缩杆270伸缩,以推拉第二活动板250开启或封堵第二通孔240。

可以理解的是,本申请实施方式中,第一活动板150开启或封堵第一通孔140的活动方式并不局限于上述实施例,第二活动板250开启或封堵第二通孔240的活动方式并不局限于上述实施例。例如,第一活动板150滑动并转动连接第一壳体130,第二活动板250滑动并转动连接第二壳体230。
本申请的实施方式中,第一腔体110与第二腔体210的断开或连通,与第一主体100与第二主体200叠合或展开,并不局限于上述实施例。
请参阅图18和图19,本申请还提供第二实施例,与第一实施例大致相同,不同的是,第一主体100与第二主体200可翻转地相互叠合或展开;当发声装置1000处于第一状态时,第一主体100与第二主体200相叠合;当发声装置1000处于第二状态时,第一主体100与第二主体200相展开。
本实施例中,第一主体100与第二主体200相展开时,第一腔体110与第二腔体210相连通,以实现第三腔体作为第一电声单元120和第二电声单元220共同的腔体,从而使得发声装置1000获得推挽式扬声器结构,使得发声装置1000的低频更纯净,输出声音质量更高。当第一主体100与第二主体200相叠合时,第一腔体110与第二腔体210相互隔绝,第一电声单元120和第二电声单元220分别独立发声,以使得发声装置1000获得双扬声器结构。当发声装置1000应用于电子设备,使得电子设备可在展开形态下,获得较大的显示面积,并且可以利用发声装置1000的推挽式发声结构,获得纯净的声音,提高用户体验。电子设备在折叠形态下,便于携带,且满足常规声音输出要求。

本实施例中,转轴基座500设有以连通或断开第一通道182和第二通道282的转接通道590。开启或关闭转接通道590,以实现隔断或连通第一通道182与第二通道282,进而实现隔绝或连通第一腔体 110与第二腔体210。发声装置1000处于第一状态时,第一壳体130与第二壳体230相互叠合,第一通道182与第二通道282分别旋转至与转接通道590的两开口错开的位置,以使得转接通道590关闭,从而第一通道182与第二通道282相互断开。当发声装置1000处于第二状态时,第一壳体130与第二壳体230相互展开,第一通道182与第二通道282分别旋转至与转接通道590的两开口正对的位置,以使得转接通道590开启,从而第一通道182与第二通道282经转接通道590相连通。
更为具体的,如图20和图21所示,第一主体100设有第一箱体191,第二主体200设有第二箱体291,发声装置1000还包括连接第一箱体191和第二箱体291的连接管道600,连接管道600设有柔性部610,柔性部610至少对应主体100与第二主体200之间可折叠区域,第一腔体110设置于第一箱体191,第二腔体210设置于第二箱体291,第一通道182和第二通道282共同形成于连接管道600内,当发声装置1000处于第一状态时,活动隔板580抵持挤压柔性部610,以使柔性部610的相对两内壁闭合,当发声装置1000处于第二状态时,活动隔板580远离柔性部610,以使柔性部610相对的两内壁张开。
连接管道600设有连接柔性部610的第一管道620和第二管道630,第一管道620连接第一箱体191,第二管道630连接第二箱体291。第一通道182设置于第一管道620内,第二通道282设置于第二管道630内,转接通道590设置于柔性部610。利用柔性部610可形变压缩或扩张,从而实现断开或开启转接通道590。
具体的,活动隔板580设置于第一转轴510和第二转轴520之间,转轴基座500还设有连接于活动隔板580、第一转轴510、第二转轴520的传动机构400,传动机构400将第一转轴510和第二转轴520的转动扭矩传递至活动隔板580,以使活动隔板580运动至隔断或开启转接通道590的位置。转接通道590设置于转轴基座500顶部,活动隔板580在转轴基座500的顶部及底部之间来回滑动。
可选的,活动隔板580滑动连接转轴基座500。活动隔板580滑动方向垂直第一转轴510。传动机构400设有固定连接活动隔板580的传动齿条460。传动齿条460与第一传动齿轮410啮合,以及与第二传动齿轮420啮合。当发声装置1000处于第一状态时,第一壳体130与第二壳体230叠合,第一传动齿轮410和第二传动齿轮420带动传动齿条460朝靠近转轴基座500顶部滑动,即带动活动隔板580滑动至靠近转轴基座500顶部,此时活动隔板580将转接通道590隔断,从而将第一通道182与第二通道282隔断,以使得第一腔体110与第二腔体210隔绝。当发声装置1000处于第二状态时,第一壳体130与第二壳体230展开,第一传动齿轮410和第二传动齿轮420带动传动齿条460朝靠近转轴基座500底部滑动,即带动活动隔板580滑动至靠近转轴基座500底部,此时活动隔板580与转接通道590分离,从而将第一通道182与第二通道282连通,以使得第一腔体110与第二腔体210连通。
当活动隔板580滑动至转轴基座500顶部,活动隔板580挤压柔性部610,从而使得转接通道590断开,即第一腔体110与第二腔体210隔绝。当活动隔板580滑动至转轴基座500底部,活动隔板580远离柔性部610,从而转接通道590开启,即第一腔体110与第二腔体210连通。
可以理解的是,利用第一主体100与第二主体200相叠合,第一主体100与第二主体200之间的空间更易于压缩,从而更加便于隔断连接管道600,以便于将第一腔体110与第二腔体210隔绝,保证第一腔体110与第二腔体210相互独立,以及第一电声单元120和第二电声单元220相互独立工作。当第一主体100与第二主体200处于非叠合状态,第一主体100与第二主体200之间的空间便于增大,从而便于连接管道600处于开启状态,进而便于将第一腔体110与第二腔体210连通,即第一主体100与第二主体200呈完全展开或半展开状态时,连接管道600都可以处于开启的状态,也就是转接通道590将第一腔体110与第二腔体210连通的状态,从而使得发声装置1000可以利用第一电声单元120和第二电声单元220结合第三腔体发声,以获得纯净声音,提高声音质量。
本申请的第一实施例和第二实施例中,第一主体100与第二主体200分别通过第一转轴510和第二转轴520相互翻转运动,当然,本申请的实施方式,第一主体100与第二主体200的转动连接结构并不局限于上述实施例。
例如,如图14所示,发声装置1000包括连接于第一主体100和第二主体200的转轴900,第一主 体100与第二主体200可通过转轴900相互翻转。转轴900固定于第一壳体130,第二壳体230设有转动连接转轴900的转动臂,转动臂可绕转轴900转动,以带动第二壳体230相对第一壳体130翻转。
本申请的第一实施例和第二实施例,第一主体100和第二主体200均是通过转轴结构相互翻转,本申请还提供一种不同于第一实施例、第二实施例结构。
请参阅图22、图23和图24,提供第三实施例,与第一实施例大致相同,不同的是,发声装置1000包括连接于第一主体100和第二主体200之间的柔性层700,第一主体100与第二主体200可通过柔性层700弯曲形变而相互翻转。
具体的,柔性层700具有第一固定边710和与第一固定边710相对第二固定边720。第一固定边710固定连接第一连接边缘135,第二固定边720固定连接第二连接边缘235。当第一主体100与第二主体200展开时,柔性层700处于展平状态,此时,发声装置1000处于第一状态,第一腔体110与第二腔体210完全隔绝。当第一主体100与第二主体200叠合时,柔性层700处于弯曲状态,此时,发声装置1000处于第二状态,第一腔体110与第二腔体210连通,发声装置1000可获得推挽式扬声器结构,以提高声音输出质量。
可以理解的是,利用第一主体100与第二主体200之间设置柔性层700,可以增加第一主体100与第二主体200的叠合方式。例如,将第一壳体130的其中一个边角与第二壳体230的处于斜对角上的边角相叠合,即第一壳体130的其中一个第一腔体110与第二壳体230的其中一个第二腔体210连通,而第一壳体130的另一个第一腔体110与第二壳体230的另一个第二腔体210相错开,使得第一主体100的部分第一电声单元120和第二主体200的部分第二电声单元220构成推挽式扬声器结构,而另一部分第一电声单元120与另一部分第二电声单元220仍然处于相互独立工作状态。
请参阅图25和图26,提供第四实施例,与第一实施例大致相同,不同的是,第一主体100与第二主体200可伸缩地相互靠拢或远离,当发声装置1000处于第一状态时,第一主体100与第二主体200相远离,当发声装置1000处于第二状态时,第一主体100与第二主体200相互靠拢。
本实施例中,第一主体100与第二主体200可相互伸缩地运动。第一主体100与第二主体200相互远离运动,使得发声装置1000呈伸长展开状态。第一主体100与第二主体200相互靠拢运动,使得发声装置1000呈收缩状态。当发声装置1000应用于电子设备时,第一主体100与第二主体200可带动显示屏300呈展平或折弯状态。当第一主体100与第二主体200相互远离,显示屏300处于展平状态,以便于电子设备获得较大显示面积。当第一主体100与第二主体200相互靠拢,显示屏300处于折弯状态,便于携带电子设备。
第一主体100与第二主体200相互伸长远离时,第一壳体130与第二壳体230分离,进而第一腔体110与第二腔体210相分离,第一腔体110与第二腔体210相互隔绝,第一电声单元120和第二电声单元220分别独立发声,以使得发声装置1000获得双扬声器结构。当第一主体100与第二主体200相靠拢时,第一壳体130与第二壳体230相抵触,从而便于第一腔体110与第二腔体210连通,第一腔体110与第二腔体210共同形成第三腔体,以实现第三腔体作为第一电声单元120和第二电声单元220共同的腔体,从而使得发声装置1000获得推挽式扬声器结构,使得发声装置1000的低频更纯净,输出声音质量更高。
具体的,第一主体100朝向第二主体200的一侧设有连通第一腔体110的第一通孔140,第二主体200朝向第二主体200的一侧设有连通第二腔体210的第二通孔240,发声装置1000包括连接第一主体100和第二主体200的伸缩结构1100,伸缩结构1100设有分别与第一通孔140和第二通孔240可滑动地开启或闭合的第一活动板150和第二活动板250,当发声装置1000处于第二状态时,伸缩结构1100带动第一活动板150和第二活动板250分别运动至开启第一通孔140和第二通孔240处,以使第一通孔140与第二通孔240连通,当发声装置1000处于第一状态时,伸缩结构1100带动第一活动板150和第二活动板250分别运动至封堵第一通孔140和第二通孔240处。
第一通孔140开设于第一壳体130朝向第二壳体230的第一侧面134,第二通孔240开设于第二壳 体230朝向第一壳体130的第二侧面234。当第一壳体130与第二壳体230靠拢时,第一壳体130朝向第二壳体230的第一侧面134,与第二壳体230朝向第一壳体130的第二侧面234相抵接,以便于第一通孔140与第二通孔240连通。

请参阅图27、图28、图29和图30,提供第五实施例,与第四实施例大致相同,不同的是,伸缩结构1100包括两端分别连接第一主体100和第二主体200的柔性件1103,第一主体100和第二主体200至少一者设有卷绕轴1104,柔性件1103可绕设于卷绕轴1104上,以带动第一主体100与第二主体200相靠拢收缩,第一活动板150设置于柔性件1103连接第一主体100的一端,第二活动板250设置于柔性件1103连接第二主体200的一端。
本实施例中,第一主体100与第二主体200之间设置可伸缩的柔性件1103,使得第一主体100可相对第二主体200滑动伸缩并且翻转运动,且第一主体100可靠拢于第二主体200的第二连接边缘235或第二端部边缘236两个位置,以实现发声装置1000可具备多种推挽式扬声器结构。
具体的,作为一种可能的实施方式,卷绕轴1104设置于第二壳体230邻近第二连接边缘235处。柔性件1103一端连接第一壳体130,柔性件1103另一端可卷绕于卷绕轴1104上。当第一壳体130与第二连接边缘235靠拢时,柔性件1103可较大部分卷绕于卷绕轴1104上,第一壳体130第一侧面134与第二壳体230的第二侧面234抵接,柔性件1103一端内缩于第一腔体110内,以使得第一活动板150开启第一通孔140,柔性件1103另一端带动第二活动板250被卷绕于卷绕轴1104上,以开启第二通孔240,从而使得第一壳体130内邻近第一连接边缘135的第一腔体110与第二壳体230内邻近第二连接边缘235的第二腔体210连通,此时发声装置1000处于第二状态。
当第一壳体130与第二端部边缘236靠拢时,柔性件1103可一部分卷绕于卷绕轴1104上,另一部分伸出,并可呈弯曲状态,以使得第一壳体130与第二壳体230叠合,第一背面133与第二背面233贴合,且第一壳体130靠近第二端部边缘236。柔性件1103的一端带动第一活动板150封堵第一侧面134上的第一通孔140,进而第一背面133的第一通孔140可与第二背面233上的第二通孔240连通,此时发声装置1000处于第二状态,以使得邻近第一连接边缘135的第一腔体110与邻近第二端部边缘236的第二腔体210连通,从而使得发声装置1000获得另一中结构形式的推挽式扬声器结构,以增加发声装置1000的发声多样性。
当柔性件1103完全展开时,第一壳体130与第二壳体230分离,柔性件1103的一端带动第一活动板150封堵第一侧面134的第一通孔140,另一端带动第二活动板250封堵第二侧面234的第二通孔240,以使得第一腔体110与第二腔体210完全隔绝,此时发声装置1000处于第一状态。
通过柔性件1103连接第一主体100和第二主体200,并且柔性件1103可卷绕于卷绕轴1104上,使得第一主体100和第二主体200可滑动伸缩,而且还可以翻转折叠,以增加发声装置1000的展开或收拢形态,增加发声装置1000的多样性。
请参阅图31和图32,提供第六实施例,与第一实施例大致相同,不同的是,第一主体100与第二主体200相对固定,发声装置1000包括连接第一主体100和第二主体200的连接部1200,连接部1200设有连通第一腔体110和第二腔体210的连通通道1201,以及设有开启或关闭连通通道1201的隔板1202,当发声装置1000处于第一状态时,隔板1202关闭连通通道1201,当发声装置1000处于第二状态时,隔板1202开启连通通道1201。
本实施例中,连通通道1201一端与第一腔体110连通,另一端与第二腔体210连通。隔板1202滑动设置于连接部1200,并且隔板1202在连通通道1201位于两端之间的位置滑动。当隔板1202滑动至隔断连通通道1201的位置,使得第一腔体110与第二腔体210相互隔绝,且第一腔体110和第二腔体210均为封闭腔体,第一电声单元120和第二电声单元220分别独立发声。当隔板1202滑动至开启连通通道1201的位置,使得第一腔体110与第二腔体210连通形成第三腔体,从而发声装置1000获得推挽式扬声器结构。
本实施例中,第一壳体130与第二壳体230一体设置,第一表面132与第二表面232平齐,第一背面133与第二背面233平齐,第一端部边缘136与第二端部边缘236相互远离。第一腔体110邻近第一端部边缘136,第二腔体210邻近第二端部边缘236。第一电声单元120可作为受话器使用,也可作为扬声器使用。第二电声单元220可作为单独的扬声器使用。连接部1200可设置与第一壳体130、第二壳体230一体成型的壳体,从而使得发声装置1000具有完整外壳。连通通道1201可由设置于壳体内器件的内腔形成,也可由设置于壳体内器件与壳体所围合的腔体形成。
通过隔板1202开启或关闭连通通道1201,使得第一腔体110与第二腔体210连通或断开,从而使得发声装置1000具备两种发声模式,并且当发声装置1000的第一腔体110与第二腔体210连通时,发声装置1000发声更加纯净,声音输出质量提高。利用第一主体100与第二主体200固定,可以使得发声装置1000结构更加稳固。当发声装置1000应用于电子设备时,发声装置1000可与不易折叠弯曲的显示屏300稳固连接,并且使得电子设备结构稳固,便于使用。
可选的,连接部1200设置电机1203和传动机构400,传动机构400连接电机1203和隔板1202。电机1203提供转动扭矩,传动机构400将电机1203的转动扭矩传递至隔板1202,以驱动隔板1202滑动,从而实现开启或关闭连通通道1201,即实现断开或连通第一腔体110与第二腔体210,以实现控制发声装置1000在第一状态和第二状态切换。
请参阅图33和图34,提供第七实施例,发声装置1000包括第一主体100和与第一主体100相叠合或展开的第二主体200,第一主体100设有第一腔体110和第一电声单元120,第二主体200设有第二腔体210;当发声装置1000处于第一状态时,第一腔体110形成第一电声单元120的音腔,第二腔体210与第二腔体210相互独立;当发声装置1000处于第二状态时,第一腔体110与第二腔体210相连通 并共同构成第一电声单元120的音腔。
本实施例中,第一主体100和第二主体200相互独立,第一主体100单独构成发声装置1000的发声部分。第二主体200可相对第一主体100展开或叠合,以改变发声装置1000的形态,从而满足发声装置1000的使用多样性。第二主体200可作为第一主体100的扩展结构,辅助第一主体100发声,第二腔体210与第一腔体110连通后形成的第三腔体,第三腔体空间增大,可提高第一电声单元120的低频声音质量。当第一主体100与第二主体200相展开时,发声装置1000可提供支撑结构,以便于发声装置1000应用于电子设备,可对电子设备的显示屏300进行展开,使得电子设备获得较大的显示面积。当第一主体100与第二主体200相叠合时,发声装置1000便于携带。
本实施例中,第一腔体110作为封闭腔体,当发声装置1000处于第一状态时,第一腔体110作为第一电声单元120的后腔,第一电声单元120的声音可经第一出音孔131出射至发声装置1000外。当发声装置1000处于第二状态时,第三腔体作为第一电声单元120的后腔,第一电声单元120的声音可以经第一出音孔131出射至发声装置1000外,而第二出音孔231可被封堵,以避免第一电声单元120出现声短路情况。
可以理解的是,当发声装置1000处于第一状态时,第一主体100与第二主体200可以是相展开状态,当发声装置1000处于第二状态时,第一主体100与第二主体200可以是相叠合状态,其相关结构与图示实施例类似,在此不再赘述。当然,在发声装置1000处于第一状态时,第一主体100与第二主体200也可以是相叠合状态,而在发声装置1000处于第二状态时,第一主体100与第二主体200可以是相展开状态,其相关结构与图示实施例类似,在此也不再赘述。
本实施例中,第一腔体110与第二腔体210隔绝或连通的结构形式可参照第一实施例、第二实施例、第三实施例和第四实施例,在此不再赘述。
通过发声装置1000处于第一状态时,第一腔体110形成第一电声单元120的音腔,第二腔体210作为独立腔体,使得发声装置1000可利用第一电声单元120单独发声,以满足常规声音输出要求,而发声装置1000处于第二状态时,第一腔体110与第二腔体210连通形成第三腔体,第三腔体构成第一电声单元120音腔,使得第一电声单元120的音腔增大,从而使得发声装置1000在另一形态下,第一电声单元120的低频声音输出质量提高,以使得发声装置1000在不同形态变化下可输出不同的声音效果,满足多样化出声要求。
可选的,第一主体100与第二主体200可通过转轴900以翻转运动的方式相互叠合或展开,也可以是通过连接件柔性件1103,以柔性件1103弯曲或展平的方式带动第一主体100与第二主体200相叠合或展开。
进一步地,请参阅图35和图36,提供第八实施例,与第七实施例大致相同,不同的是,第二腔体210内设置倒相管211。
本实施例中,倒相管211具有第一开口端2111和与第一开口端2111相对的第二开口端2112。第一开口端2111朝向第二腔体210外侧设置,第二开口端2112朝向第二腔体210内侧设置。倒相管211的第一开口端2111与第一出音孔131连通,以便于将第二腔体210内的气流从第一开口端2111经第一出音孔131释放出去。
当发声装置1000处于第一状态时,第一腔体110与第二腔体210相互隔绝,即倒相管211与第一电声单元120的音腔隔绝,第一腔体110作为第一电声单元120的后腔,第一腔体110为封闭音腔,第一电声单元120的声音经第一出音孔131发出,以使得发声装置1000可以获得常规扬声器结构。当发声装置1000处于第二状态时,第一腔体110与第二腔体210连通形成第三腔体,第三腔体形成第一电声单元120的后腔,且第三腔体内设置倒相管211。第一电声单元120朝第三腔体内发出振动波,与第一电声单元120朝第三腔体外发出的振动波相位相反,然而由于振动波的惯性滞后,第三腔体内的振动波传导至倒相管211,经倒相管211射出后再次形成相位相反的振动波,使得倒相管211输出的振动波与第一电声单元120朝第三腔体外发出的振动波刚好产生共振,使得发声装置1000出射的低频声音更 佳优异。
可以理解的是,相较于常规的扬声器结构,在发声装置1000处于第二状态下,第一腔体110与第二腔体210连通,倒相管211可与第一电声单元120共同协作,使得发声装置1000获得倒相管式扬声器结构。发声装置1000可以利用第一电声单元120朝第三腔体外发出的声波与倒相管211朝第三腔体发出的声波共振,进而在声压不变的情况下,扩展了低频。发声装置1000在第二状态下,与常规封闭式扬声器相比,当常规封闭式扬声器需要达到同等低频效果下,封闭式扬声器的后腔需要扩大,也就是说,发声装置1000用于发声的第三腔体可比密闭式扬声器的后腔小70%,因此发声装置1000在第二状态下对功率放大器输出功率的要求比常规的密闭式扬声器更低。发声装置1000处于第二状态下,倒相管211可以减小低频下限频率附近的振动波振幅失真。也就是说,发声装置1000在第二状态下,可以达到效率高、低频特性好、较小体积就可满足较优的低频特性等优点。
可以理解的是,当发声装置1000处于第一状态时,第一主体100与第二主体200可以是相展开状态,当发声装置1000处于第二状态时,第一主体100与第二主体200可以是相叠合状态,其相关结构与图示实施例类似,在此不再赘述。当然,在发声装置1000处于第一状态时,第一主体100与第二主体200也可以是相叠合状态,而在发声装置1000处于第二状态时,第一主体100与第二主体200可以是相展开状态,其相关结构与其他实施例类似,在此也不再赘述。
本实施例中,第一腔体110与第二腔体210隔绝或连通的结构形式可参照其他实施例,在此不再赘述。

在第一实施例中,及第三实施例中,电子设备2000处于展开形态时,发声装置1000处于第一状态,第一电声单元120和第二电声单元220相互独立发声,即电子设备2000可获得多个独立发声的扬声器结构。当电子设备2000处于折叠形态时,发声装置1000处于第二状态,第一腔体110与第二腔体210连通,第一电声单元120和第二电声单元220可结合第三腔体共同构建推挽式扬声器结构,以使得电子设备2000输出的声音质量提高。

在第七实施例中,第一部分310和第二部分320分别固定于贴合于第一壳体130和第二壳体230, 由于第一壳体130与第二壳体230一体固定,从而整个显示屏300可固定贴合与第一壳体130和第二壳体230上,发声装置1000对显示屏300可有效支撑稳固。显示屏300可以为非折叠显示屏,以便于电子设备2000简化结构,且可提供多种发声模式。
在第八实施例中,显示屏300与发声装置1000的连接形式与第一实施例和第二实施例大致相同,在此不再赘述。
