Description

耳机、耳机控制方法及系统 技术领域
本发明涉及数据处理领域，具体地说，涉及一种耳机、耳机控制方法及系统。
背景技术
入耳式耳机具有容积小、方便携带/收纳等优点，而一款耳机的音质在其出厂时即已确定，使用者只能通过耳机的品牌、该款耳机的口碑或者实际体验选择自己认为理想的耳机。
由于耳机结构设计的差异，扬声器不一定能发挥最佳的效果，也不一定能满足使用者当下所需要情境，譬如语音通话情景下，过强的高频及低频会影响收听方的接收到的语音的清晰度，适度地降低低频环境噪音(如风切声、外界噪声)及高频的噪声(语音不需要高频段)可有效地突显语音内容，使得信息传递更精准。
现有的采用主动降噪算法(Active Noise Cancellation，ANC)的蓝牙耳机(True Wireless Stereo，TWS)的通透模式虽可减少用户取/戴耳机的困扰，但需要消耗耳机有限的电量，外界音强化模式也可能存在不真实化的状况，透过前音腔直接接收无损的外界音，最能接近真实。
需要说明的是，在上述背景技术部分公开的信息仅用于加强对本发明的背景的理解，因此可以包括不构成对本领域普通技术人员已知的现有技术的信息。
发明内容
针对现有技术中的问题，本发明的目的在于提供了一种耳机、耳机控制方法及系统，本发明的耳机通过设置有的驱动组件调节发声单元的位置，从而调节耳机的前音腔与外界的连通状态，以实现耳机在通透模式和其他模式之间的切换。
本发明的实施例提供了一种耳机，包括：

第二壳体，所述第二壳体与所述第一壳体连接形成壳体，所述壳体上设置有一声音通道；
发声单元，容置于所述壳体内，所述发声单元将所述壳体分为所述发声单元与在所述导音件一侧的所述壳体形成的前音腔，以及所述发声单元与所述壳体的另一侧形成的后音腔；
驱动组件，用于驱动所述发声单元处于远离所述导音件的第一位置范围或处于靠近所述导音件的第二位置范围；
当所述发声单元处于第一位置范围时，所述声音通道与所述前音腔相连通；

根据本发明的一些实施例，当所述发声单元处于语音位置范围时，所述声音通道关闭；
当所述发声单元处于乐音位置范围时，所述声音通道与所述后音腔相连通。
根据本发明的一些实施例，所述声音通道设置于所述第二壳体与所述第一壳体的连接处或设置于所述第二壳体上。
根据本发明的一些实施例，所述驱动组件为音圈马达。
根据本发明的一些实施例，所述音圈马达包括底座、与所述底座连接的马达本体和与所述马达本体连接的移动音圈，所述移动音圈与所述发声单元相抵接。
根据本发明的一些实施例，所述耳机还包括触控感应组件，用于接收调节所述发声单元的位置的触控信号。
本发明的一些实施例还提供了一种耳机控制方法，用于控制上述耳机，包括以下步骤：
判断是否接收到触发信号；
如接收到触发信号，则判断所述触发信号的类型；
如所述触发信号为第一类型信号，则驱动组件驱动所述发声单元使其处于第一位置范围；
如所述触发信号为第二类型信号，则驱动组件驱动所述发声单元使其处于第二位置范围。
根据本发明的一些实施例，所述第二位置范围包括语音位置范围和乐音位置范围；
所述方法还包括如下步骤：
如未接收到触发信号，则判断是否接收到音频信号；
如接收到音频信号，则判断所述音频信号的类型；
如所述音频信号为语音通话类型，则驱动组件驱动所述发声单元使其处于所述语音位置范围；
如所述音频信号为乐音类型，则驱动组件驱动所述发声单元使其处于所述乐音位置范围。
根据本发明的一些实施例，所述耳机还包括触控感应组件，通过所述触控感应组件接收所述触发信号。
本发明的一些实施例还提供了一种耳机控制系统，用于所述耳机控制方法，包括控制模块和驱动模块；
所述控制模块用于判断是否接收到触发信号和判断所述触发信号的类型；
所述驱动模块用于向所述驱动组件发送指令，使得所述驱动组件驱动所述发声单元处于远离所述导音件的第一位置范围或处于靠近所述导音件的第二位置范围。
本发明的耳机设置有与发声单元相连接的驱动组件，耳机的壳体具有与外界相连通的声音通道，通过驱动组件可调节发声单元的位置，从而调节耳机的前音腔与外界的连通状态，以实现耳机在通透模式和其他模式之间的切换。
本发明的耳机的处于通透模式时，前音腔通过声音通道与外界相连通，使得使用者直接通过出音孔或者耳廓集音听到外界声音，达到通透效果，实 现无须透过麦克风收外界音，直接接收无损的外界音，保留外界真实声音。
同时，本发明的耳机还可以通过调节发声单元的位置调节前音腔和后音腔容积的大小，实现耳机在通透模式、语音模式和乐音模式之间的切换。本发明的耳机的处于乐音模式时，前音腔容积的减小可有效地提升高频段频响声压，并使频响频段向高频延伸，音质具有更好的空间感；同时，后音腔的容积增大且与外界相连通，有效地提升低频段频响，低音更有力度。本发明的耳机的处于语音模式时，前音腔容积增大，高频段声压下降，低频段频响降低，有助于减少语音通话下的低频噪声(例如风切声等)及高频噪声干扰，降低环境音与噪声对通话质量的影响；同时，前音腔容积增大提升中频段频响，有助于语音通话状态下的清晰度，即本发明的耳机可以同时满足听媒体音频与通话时的对音质的不同要求。
相较于现有的耳机通过调整均衡器(Equalizer，EQ)来改变耳机的对声音频率的响应，如采用双麦克风设计，透过外部麦克风和放大器将外部声音引入耳道，使得佩戴者能够听到环境音，此设计增加电池耗电量及存在外界音失真。本发明的耳机通过调节发声单元的位置有效地改变耳机的对声音频率的响应，节省耳机电池耗电量；同时，通透模式也无需耳机电池电量的消耗，因此，本发明的耳机电池耗电量更小，同样电池使用时间更长。

图1为本发明一实施例的耳机的结构爆炸图，图2为该实施例的耳机处于通透模式时的剖面结构图，所述耳机包括：
第一壳体100，包括设置有出音孔111的导音件110；
第二壳体200，所述第二壳体200与所述第一壳体100连接形成壳体，所述壳体上设置有一声音通道900；
发声单元300，容置于所述壳体内，所述发声单元300将所述壳体分为所述发声单元300与在所述导音件110一侧的所述壳体形成的前音腔，以及所述发声单元300与所述壳体的另一侧形成的后音腔；驱动组件400，用于驱动所述发声单元300处于远离所述导音件110的第一位置范围或处于靠近所述导音件110的第二位置范围；
当所述发声单元300处于第一位置范围时，所述声音通道900与所述前音腔相连通；
当所述发声单元300处于第二位置范围时，所述声音通道900与所述前 音腔不相连通。
需要说明的是，耳机内部音腔可以看成是由耳机壳体的内腔构成，发声单元将之分隔为前音腔和后音腔，发声单元出声的一侧为前音腔，另一侧为后音腔。第一位置范围和第二位置范围均是位置范围，即非一个位置点，使得声音通道900与前音腔相连通的发声单元300的位置均属于第一位置范围，同理，使得声音通道900与前音腔不相连通的发声单元300的位置均属于第二位置范围。
本发明的耳机通过在壳体内设置与发声单元300相连接的驱动组件400，且在壳体上设置与外界相连通的声音通道900，并且通过驱动组件可调节发声单元300的位置，从而调节耳机的前音腔与外界的连通状态。具体为，当需要听到外界声音时，即控制发声单元300移动至第一位置范围，此时，声音通道900与前音腔相连通，此模式定义为通透模式，在此模式下，使用者可以在不取下耳机的情况下，直接通过出音孔111或者耳廓集音听到外界声音，达到通透效果，实现无须透过麦克风收外界音，直接接收无损的外界音，保留外界真实声音。当需要听媒体音频或者是语音通话时，则使用其他模式，即控制发声单元300移动至第二位置范围，此时，声音通道900与前音腔不相连通，出音孔111为发声单元所发出的声音。本发明的耳机通过声音通道900和发声单元300位置的调节实现耳机在通透模式和其他模式之间的切换。
耳机对前音腔和后音腔的容积的不同设置可影响声音的临场感和音频中各频段的表现，通常，前音腔容积越小时，中、高频越向高频段延伸；后音腔容积越大时，低频截止频率越向低频段延伸。进一步的，在本发明的实施例中，所述第二位置范围可以包括语音位置范围和乐音位置范围；所述语音 位置范围与所述导音件110的距离大于所述乐音位置范围与所述导音件110的距离。
当发声单元300处于乐音位置范围时，前音腔的容积较小，前音腔容积的减小可有效地提升高频段频响声压，并使频响频段向高频延伸，音质具有更好的空间感；前音腔容积的减小同时意味着后音腔容积的增大，后音腔容积的增大可有效地提升低频段频响，此时，低音更有力度，适用于媒体音频信号的播放，此模式定义为乐音模式。
而当耳机处于语音通话时，希望高频段声压下降，低频段频响降低，以减少语音通话下的低频噪声及高频噪声干扰，从而降低环境音与噪声对通话质量的影响，此时，需要增大前音腔容积，在本发明中，可以通过驱动组件驱动发声单元300做远离导音件110的移动，语音位置范围相对与乐音位置范围更远离导音件110，前音腔容积增大提升中频段频响，有助于提高语音通话状态下语音的清晰度，此模式定义为语音模式。
为了进一步提升低频段频响，提高低音的力度，在实施例中，当所述发声单元300处于语音位置范围时，所述声音通道900关闭，此时声音通道900不与耳机的前音腔或后音腔相连通，见图3的本发明一实施例的耳机处于语音模式时的剖面结构图；但是，当所述发声单元300处于乐音位置范围时，所述声音通道900与所述后音腔相连通，此时后音腔与外界相连通，见图4的本发明一实施例的耳机处于乐音模式时的剖面结构图。后音腔容积相较于语音模式增大和后音腔与外界相连通均对提升低频段频响、提高低音力度起作用。
同样地，语音位置范围和乐音位置范围均是位置范围，非一个位置点， 使得声音通道900关闭的发声单元300的位置均属于语音位置范围，使得声音通道900与后音腔相连通的发声单元300的位置均属于乐音位置范围。
本发明的耳机通过发声单元300远离或靠近导音件110实现语音模式和乐音模式之间的转换，可以同时满足听媒体音频与通话时的对音质的不同要求。
在此实施例中，第一位置范围、语音位置范围、乐音位置范围依次靠近导音件110，通过声音通道900和发声单元300在上述位置的调节实现耳机在通透模式、语音模式和乐音模式之间切换。该实施例的耳机可以具体包括：
耳机还可以包括耳机盖500，所述耳机盖500与所述导音件110相连接，所述导音件110与所述第二壳体200相连接。所述耳机盖500与所述导音件110可以采用扣接的方式连接；所述导音件110与所述第二壳体200也可以采用扣接的方式连接；耳机盖与导音件、导音件与第二壳体之间的连接方式不限于上述扣接方式。
第二壳体200有可以具体包括第二壳盖210和盖板220，第二壳体200也可以上一体件。所述声音通道900设置于所述第二壳体200与所述第一壳体100的连接处，在此实施例中，连接处具体为第一壳体100的导音件110与第二壳体200的连接处。
声音通道900可以是在第一壳体和第二壳体连接处的穿孔狭缝，在第二壳体200与第一壳体100的连接处设置声音通道900的优点在于制造工序上的便捷性。由于前音腔和后音腔容积直接影响发声单元所发出的声音通过出音孔传到使用者耳朵的听觉效果，可以通过设置第一壳体100与第二壳体200的尺寸控制前音腔和后音腔可调节的容积范围。当然，声音通道900也可以 是设置在耳机壳体的其他位置的穿孔狭缝，如设置于第二壳体200上，见图1，穿孔狭缝的尺寸可根据音质效果设定。设定的声音通道900因发声单元300位置的变化，起到不同的作用，当声音通道900与前音腔连通时，则起到透音孔的作用，与后音腔连通时，则起到低音孔的作用。声音通道因发声单元的变位改变作用，提升了耳机方便性及多用性。
本发明的驱动组件不限，可容置于耳机的壳体中且可以驱动发声单元在远离和靠近导音件的位置移动即可。
在一些实施例中，所述驱动组件400采用音圈马达，尤其是直线型的音圈马达。音圈马达(Voice Coil Actuator/Voice Coil Motor)是一种将电能转化为机械能的装置。音圈马达利用来自永久磁钢的磁场与通电线圈导体产生的磁场中磁极间的相互作用产生有规律的运动的装置，其定位精度取决于反馈及控制系统，可以实现高频响应、高精度的移动定位，且有使用寿命长的特点。
如图1至图4所示，所述音圈马达可以包括底座410、与所述底座410连接的马达本体420和与所述马达本体420连接的移动音圈430，所述移动音圈430与所述发声单元300相抵接。音圈马达的底座410可以固定于第二壳体200的盖板220上，发声单元300与音圈马达相抵接，音圈马达的移动音圈430的沿轴(OO’)方向的运动可控制发声单元300靠近或远离导音件110。实际的使用中，发声单元300不限种类，可以为动圈式扬声器、陶瓷扬声器或平衡电枢式扬声器。发声单元300的外圈也可以包覆具自润性气密效果的指聚四氟乙烯(Poly tetra fluoroethylene，PTFE)O型圈，以确保发声单元300在耳机壳体腔内的位置改变时，音质会由于前音腔和后音腔容积的变 化而跟着相应变化。
上述耳机可以为无线耳机，也可为有线耳机。当耳机为无线耳机时，为了能通过耳机本身就有接收调节发声单元的移动位置的信号，在另一些实施例中，所述耳机还可以包括触控感应组件，用于接收调节所述发声单元300的位置的触控信号。
现有的无线耳机采用双麦克风设计，透过外部麦克风和放大器将外部声音引入耳道，使得佩戴者能够听到环境音，此设计增加电池耗电量及存在外界音失真。相较于现有的无线耳机，本发明的耳机通过调节发声单元的位置有效地改变耳机的对声音频率的响应，节省耳机电池耗电量；同时，通透模式也无需耳机电池电量的消耗，因此，本发明的耳机电池耗电量更小，同样电池使用时间更长。
本发明的耳机不仅可以通过前音腔和后音腔的容积的设定影响声音的临场感和音频中各频段的表现，在前音腔还可以设置泄音孔、导音管海绵、导音管调音纸等，如前音腔设置泄音孔，就听觉感受而言，如泄漏的量愈多，则隔离外界噪音的成份就愈少，也就是愈容易听到外界的声音；在后音腔则可以设置微型扬声器通气孔、通气调音网布等，在此不再赘述。
本发明的一些实施例还提供了一种耳机控制方法，用于控制上述耳机，图5为本发明一实施例的耳机控制方法的流程图，具体地，该控制方法包括以下步骤：
S100：判断是否接收到触发信号；
如接收到触发信号，则S110：判断所述触发信号的类型；
如所述触发信号为第一类型信号，则S111：驱动组件驱动所述发声单元 使其处于第一位置范围，即耳机处于通透模式；
如所述触发信号为第二类型信号，则S112：驱动组件驱动所述发声单元使其处于第二位置范围。
上述触控信号可以是通过与耳机相通讯的终端接收到的触控信号，终端可以包括用户使用的任意形态可以与耳机相通讯的电子设备，可以为手机、平板电脑、个人数字助理(Personal Digital Assistant，PDA)、数码相框、媒体播放器、手表装置、挂件装置、耳机或耳机装置、导航装置、可穿戴或微型装置等，类型不做限定。
在一些实施例中，可以在耳机上设置触控感应组件，通过所述触控感应组件接收所述触发信号。举例来说，触控信号可以通过对触控感应组件的触敏表面的触摸触控操作形成。触摸触控操作是指用户身体部位(手部、手肘等)或触控笔直接接触触敏表面的操作，如单次点击、双次点击或三次点击的触控屏等。
上述使发声单元处于第一位置范围，即耳机处于通透模式的第一类型信号可以设定为一触摸触控操作，如单次点击触控屏，同样地，将另一触摸触控操作设定为第二类型信号，如双次点击触控屏，在此不再赘述。
图6为本发明又一实施例的耳机控制方法的流程图，所述第二位置范围包括语音位置范围和乐音位置范围；
所述方法还包括如下步骤：
如未接收到触发信号，则S120：判断是否接收到音频信号；
如接收到音频信号，则S130：判断所述音频信号的类型；
如所述音频信号为语音通话类型，则S131：驱动组件驱动所述发声单元 使其处于所述语音位置范围；
如所述音频信号为乐音类型，则S132：驱动组件驱动所述发声单元使其处于所述乐音位置范围。
如未接收到音频信号，则驱动组件不做驱动，发声单元处于原来位置状态。
当本发明的耳机为无线耳机时，无线耳机的音频传输模型协定包括：HSP(HeadsetPro-file)、HFP(HandProfile)、A2DP(Advanced Audio Distribution Profile)和AVRCP(Audio Video Remote Cortrol Profile)。此时，S130步骤判断所述音频信号的类型可根据音频信号传输的协定的类型来判断。如HSP和HFP传输的为电话音频，则认为该音频信号是语音通话类型的，A2DP和AVRCP传输的为媒体音频，则认为该音频信号是乐音类型的。
上述耳机控制方法运用于实际场景时，系统实时监测并判断是否接收到触发信号，如接收到，则执行S110至S111，或执行S110至S112步骤；如未接收到，则执行S120至S131，或执行S120至S132步骤。
当然，上述耳机控制方法也可以是系统在执行S120至S131，或接执行S120至S132步骤时，如系统实时监测并判断为接收到触发信号状态，则触发执行S111或触发执行S112步骤。上述方法中，将触发信号作为优先级的控制信号。触发信号与系统信号之间的优先级也可通过系统设定或者修改，本发明不对此做限定。
本发明的一些实施例还提供了一种耳机控制系统，用于上述耳机控制方法，图7为本发明一实施例的耳机控制系统的结构示意图，耳机控制系统包括控制模块M100和驱动模块M200；
所述控制模块M100用于判断是否接收到触发信号和判断所述触发信号的类型；
所述驱动模块M200用于向所述驱动组件发送指令，使得所述驱动组件驱动所述发声单元使其处于第一位置范围或第二位置范围，当然，上述耳机控制系统可以包括用于声音输出至耳机的声音模块M300、用于接收触发信号的信号接收模块M400等。
实施例的耳机控制系统中的各个功能模块的功能实现方式均可以采用上述耳机控制方法中各个步骤的具体实施方式来实现。例如，控制模块M100和驱动模块M200可以分别采用上述步骤S100至S111、步骤S100至S112、步骤S100至S131、步骤S100至S132的具体实施方式实现其功能，此处不予赘述。
综上所述，本发明的耳机通过在壳体内设置与发声单元相连接的驱动组件，且在壳体上设置与外界相连通的声音通道，并且通过驱动组件可调节发声单元的位置，从而调节耳机的前音腔与外界的连通状态，以实现耳机在通透模式和其他模式之间的切换。
本发明的耳机的处于通透模式时，前音腔通过声音通道与外界相连通，使得使用者直接通过出音孔或者耳廓集音听到外界声音，达到通透效果，实现无须透过麦克风收外界音，直接接收无损的外界音，保留外界真实声音。
同时，本发明的耳机还可以通过调节发声单元的位置调节前音腔和后音腔容积的大小，实现耳机在通透模式、语音模式和乐音模式之间的切换。本发明的耳机的处于乐音模式时，前音腔容积的减小可有效地提升高频段频响声压，并使频响频段向高频延伸，音质具有更好的空间感；同时，后音腔的 容积增大且与外界相连通，有效地提升低频段频响，低音更有力度。本发明的耳机的处于语音模式时，前音腔容积增大，高频段声压下降，低频段频响降低，有助于减少语音通话下的低频噪声(例如风切声等)及高频噪声干扰，降低环境音与噪声对通话质量的影响；同时，前音腔容积增大提升中频段频响，有助于语音通话状态下语音的清晰度，即本发明的耳机可以同时满足听媒体音频与通话时的对音质的不同要求。
本发明的耳机通过调节发声单元的位置有效地改变耳机的对声音频率的响应，节省耳机电池耗电量；同时，通透模式也无需耳机电池电量的消耗，因此，本发明的耳机电池耗电量更小，同样电池使用时间更长。
以上内容是结合具体的优选实施方式对本发明所作的进一步详细说明，不能认定本发明的具体实施只局限于这些说明。对于本发明所属技术领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干简单推演或替换，都应当视为属于本发明的保护范围。
