具体实施方式 Detailed ways

[0021] 为使本发明的目的、技术方案和优点更加清楚,下面将结合附图对本发明实施方式作进一步地详细描述。 [0021] To make the objectives, technical solutions, and advantages of the present invention will become apparent in conjunction with the accompanying drawings of the following embodiments of the present invention will be described in further detail.

[0022] 本发明一个实施例提供了一种耳机环境声音的调节方法。 [0022] An embodiment of the present invention provides a method for adjusting an earphone ambient sound. 参见图1,示出了应用本方案的一个场景,该方法包括:在耳机外侧设置至少一个采集环境声音的外置麦克风,如连接至降噪模块的MICl和连接至监听模块的MIC2。 Referring to Figure 1, shows an application scenario of the present embodiment, the method comprising: on the outside of the earphone microphone is provided at least one collecting external sound environment, such as noise reduction module connected to the monitoring module MICl and connected to the MIC2. 在一种变形的方式中,可利用同一个外置麦克风分别与降噪模块和监听模块连接,实现降噪和监听。 In a variant of embodiment may be utilized with an external microphone is connected to the noise reduction module and the monitoring module, listening, and noise reduction. 在耳机外壳上设置机械式可移动的调节器,调节器具有电气端口,通过电气端口将调节器连接至耳机的降噪模块和/或监听模块。 Earphone housing disposed on a movable mechanical regulator, the regulator having electrical ports, electrical ports by the regulator module connecting to a headset noise reduction and / or monitoring module. 降噪模块和监听模块可以集成在耳机的主控芯片上,由一个芯片实现,或者在耳机内分别设置分立的器件实现降噪模块和监听模块。 Noise reduction module and the monitoring module may be integrated on the headset master chip, one chip or a set of discrete modules, and noise reduction devices are in listening module headset.

[0023] 参见图2,本实施例提供的耳机环境声音的调节方法还包括: [0023] Referring to Figure 2, the present embodiment of the method for adjusting the headphone sound environment provided by further comprising:

[0024] S201:主控芯片实时监测调节器的移动状态,当调节器发生移动时,获知调节器的移动量和移动类型。 [0024] S201: control chip real-time monitoring of the movement state actuator, when the actuator moves, known amount adjuster movement and movement type.

[0025] S202:主控芯片根据移动类型确认当前的调节类型,并根据移动量确认当前对环境声音的调节量。 [0025] S202: The mobile main control chip type current adjustment to confirm the type, the amount of adjustment and the amount of movement of the ambient sound to confirm this.

[0026] S203:主控芯片按照确认的调节类型,控制降噪模块或监听模块采用确认的调节量对麦克风采集到的环境声音进行调节。 [0026] S203: A validation master chip type regulation, control or monitoring module uses the noise reduction module confirmation amount adjusting microphone to collect the ambient sound is adjusted.

[0027] 在噪声背景下进行通信时,耳机会采用降噪模块。 [0027] When communicating in noisy background, noise reduction module using the headset. 降噪模块采用前馈式(Feed-Forward,FF)降噪、反馈式(FeedBack,FB)降噪或者是前馈加反馈的混合降噪。 Noise Noise feedforward modules (Feed-Forward, FF), feedback (FeedBack, FB) or noise is mixed feedforward plus feedback noise. 目前的降噪主要考虑如下两个方面:一方面是在通信设备送话端采用声学信号处理技术提高传声器拾取的语音信号的信噪比,使得远端用户能够听清近端用户的讲话。 Noise Consider now two main aspects: one is the use of acoustic signal processing techniques at the sending end communication apparatus improve the SNR of the voice signal picked up by the microphone, so that the user can hear the distal end of the proximal end of the user's speech. 另一方面需要在通信设备受话端提高受话端语音的信噪比,使得近端能够听清远端用户送过来的语音信号。 And the need to improve the SNR at the receiving end of voice communication apparatus receiving end, a proximal end that can be sent over the remote user to hear a voice signal.

[0028] 另外一些场景中,为了在有需要的时候不拿下耳机也可以方便地和外界进行通话或者是对外界环境噪声进行监听,耳机会采用监听模块,对外界环境中的声音进行放大,保证佩戴者能够听到外界声音。 [0028] In some other scenarios, in order not to win the headset when necessary and can be easily performed outside call or listen to the external ambient noise, the headset will use the monitoring module, the external environment of the sound is amplified, to ensure that the wearer can hear outside sounds. 现有具有监听功能的耳机,也仅仅具有开启监听功能和关闭监听功能两种方式,这种直接实现监听功能的有无,不能给耳机佩戴者带来好的用户体验。 Existing headset has a monitoring function, it is only with a monitoring function to open and close monitoring functions two ways, whether direct implementation of this monitoring function, the user can not bring good experience to the headphone wearer.

[0029] 上述步骤S201至S203也可以由降噪模块或监听模块实现,可以由降噪模块或监听模块对调节器的移动进行监测。 [0029] The above-described steps S201 to S203 may be realized by the noise reduction module or the monitoring module, the movement actuator can be monitored by a monitoring module or modules noise.

[0030] 本实施例可以应用在耳机中仅存在降噪模块和监听模块中的一种的场景,这时调节器移动时,仅对应一种移动类型,例如,当仅存在降噪模块时,若监测到调节器移动,则调节器的移动类型仅对应于降噪的调节类型。 [0030] The present embodiment can be applied there is only one noise reduction module and the monitoring module of the scene in the headset, then the regulator moves, only the corresponding type of a mobile, e.g., when only noise reduction module, If the monitor moves to the regulator, the regulator of the mobile type corresponding to only adjust the type of noise.

[0031] 本发明实施例的技术方案,通过调节器的移动会得到多个不同渐变的移动量,不同的移动量对应于不同的调节量,从而能够根据需要任意调节降噪量的大小或监听到的环境声音的音量大小,解决了现有方案只能单一选择降噪功能开启或者关闭带来的问题,实现了耳机对环境声音的灵活调节,使耳机功能更人性化,增强了耳机性能,提高了用户体验。 [0031] The technical solutions in the embodiments of the present invention, a plurality of different movement amount obtained by the gradient of the regulator will be moved, different movement amount corresponding to different adjustment amount, it is possible to arbitrarily adjust the amount of noise reduction required size or monitor to the volume of the sound environment to solve the existing programs can only select a single noise reduction function on or off problems caused realize the headset flexible adjustment of the ambient sound of the headset features a more user-friendly, enhanced performance headphones, improve the user experience.

[0032] 在图2所示实施例的基础上,进一步的,本发明实施例还包括:根据调节器的移动行为,将调节器的移动状态划分为包括对应于降噪控制的第一移动类型,以及对应于监听控制的第二移动类型。 [0032] In the embodiment based on the embodiment shown in Figure 2, a further embodiment of the present invention further comprising: the mobility behavior of the actuator, the movement state actuator is divided into a first type of movement corresponds to a noise control and a second monitor corresponding to the type of movement control. 其中,利用降噪模块执行降噪控制,利用监听模块执行监听控制。 Wherein the noise reduction is performed using a noise reduction module control snoop control performed using the monitoring module.

[0033] 根据调节器的具体实现方式不同,调节器的移动行为也不同,如调节器为旋钮时,调节器的移动行为可以包括向左旋转、向右旋转。 [0033] According to a particular implementation of a different regulator, the regulator movement behavior are different, such as when the regulator knob movement behavior may include a rotary actuator to the left, right rotation.

[0034] 本实施例通过将调节器的移动状态划分为两种移动类型,以利用同一调节器实现调节降噪和调节监听两种功能。 [0034] In this embodiment, the movement state actuator is divided into two types of movement, in order to use the same noise reduction and regulation regulator to adjust the monitor to achieve two functions. 这主要考虑到降噪和监听的功能其实是相反的两个作用效果,采用同一个结构件的方式来实现两种功能的调节,能够在保证耳机功能的同时,简化耳机的结构。 This is the main consideration, and the function of monitoring the noise actually two opposite effects, adjustment is implemented with two functions in the same manner as a structural member, it is possible to ensure the function of the headset while simplifying the structure of the headset. 本实施例主要以设置一个调节器为例的场景进行说明,但并不局限于此,本实施例也可以设置两个调节器,一个调节器用于实现降噪控制,一个调节器用于实现监听控制。 This embodiment mainly regulator to set a scene will be described as an example, but not limited thereto, the present embodiment may also be provided two regulators, one regulator for control of noise reduction, for implementing a snoop control regulator .

[0035] 则上述方法还包括:在一次监测过程中,主控芯片可以执行下述的一种操作: [0035] The above method is further comprising: a monitoring process, the master chip may perform one of the following operations:

[0036] 当主控芯片监测到调节器发生的移动属于第一移动类型时,确认当前的调节类型为降噪控制,并根据移动量确认当前对环境声音的降噪量; [0036] When the mobile main control chip to the regulator monitors occurrence belongs to the first type of movement, for the confirmation of the current noise control type regulator, and confirm that the current amount of noise reduction of the amount of movement of the ambient sound;

[0037] 当主控芯片监测到调节器发生的移动属于第二移动类型时,确认当前的调节类型为监听控制,并根据移动量确认当前对环境声音的放大量 [0037] When the master chip to monitor the movement of the regulator belonging to a second mobile type that occur, for the confirmation of the current regulator type snoop control, and confirms the current sound environment of the large discharge amount of movement

[0038] 当耳机上设置有两个调节器时,主控芯片可以针对两个调节器的移动,同时执行上述两种操作,或者仅执行上述一种操作。 [0038] When the regulator is provided with two headphone, the master chip may be moved for both regulators, while performing both operations, or to perform only one of the above operations.

[0039] 主控芯片可以预先维护一个移动量和调节量的对应关系表,根据移动量查询移动量和调节量的对应关系,即可快速得到当前对环境声音的调节量。 [0039] a master chip may be maintained in advance and the amount of movement adjustment amount correspondence table, the amount of movement and the amount of the query corresponding relationship between the adjustment amount of movement to quickly obtain this amount of adjustment of the ambient sound. 这种方式,在进行监测时,不需要实时对降噪量或放大量进行计算,能够快速得到当前所使用的降噪量或放大量,提高耳机对环境声调节的速度。 In this manner, during the monitoring, does not require real-time or to put a lot of noise reduction is calculated, the amount of noise reduction can be obtained quickly currently used or amount of amplification, to improve regulation of the ambient sound velocity headphone pair.

[0040] 本发明又一实施例主要对调节器的工作方式进行说明,耳机环境声音调节方案的其他内容可以参见本发明的其他实施例。 [0040] A further embodiment of the present invention mainly works regulator is described, other content headphones ambient sound regulation scheme can be found in other embodiments of the present invention.

[0041] 通过旋钮实现调节器时,在调节器的旋转轨迹上设置旋转分界点,如将旋转轨迹的中间点作为旋转分界点,主控芯片(或降噪模块)监测到旋钮向旋转分界点的预定一侧(如左侧)旋转时,获知旋钮的移动类型为第一移动类型,主控芯片(或监听模块)监测到旋钮向旋转分界点的另一侧(如右侧)旋转时,获知旋钮的移动类型为第二移动类型,并由旋钮的旋转量得到所述移动量。 [0041] is achieved by adjusting knob is provided on a rotary cut-off point of rotation locus regulator, such as the intermediate point of the rotary locus of rotation as the demarcation point, the master chip (or noise reduction module) to monitor the rotation knob demarcation point a predetermined side (e.g., left side) is rotated, movement of known type knob is a first type movement, the master chip (or a monitor module) to monitor the rotation of the knob to the other side of the demarcation point of rotation (right-side), moving a second type known as a mobile type knob, the knob rotation amount obtained by said movement amount. 参见图3,示出了调节器的一种实现方式。 Referring to Figure 3, there is shown one implementation of the regulator. 调节器为旋钮,与头戴式耳机的听筒部分同轴装配,为每一个听筒设置一个调节器,调节器位于听筒部分壳体的外端,一个调节器负责同侧的听筒的环境声音的调节。 Ambient sound regulator is a knob, and the ear portion coaxially assembled headset, an earpiece is provided for each of a regulator, the regulator on the outer end portion of the housing of the handset, a handset is responsible for regulating adjustment ipsilateral . 设置作为调节器的旋钮具有一定的大小和厚度,便于人手握持,例如调节器可以为具有一定厚度的圆盘部件。 Knob provided with a certain size and thickness, to facilitate manual grasping, for example, the regulator member may be a disk having a predetermined thickness.

[0042] 或者,参见图4,示出了调节器的另一种实现方式。 [0042] Alternatively, referring to FIG. 4, there is shown a regulator another implementation. 调节器为旋钮,该旋钮突出听筒壳体外侧一定高度,以便于人手握持,旋钮不与调节器同轴装配,旋钮为柱体部件。 Regulator is a knob which protrudes outside the receiver housing to a certain height, so as to hand grip, knob coaxially regulator assembly does not, the knob of the cylinder member.

[0043] 通过推钮实现调节器时,在调节器的推动行程上设置行程分界点,监测到推钮向行程分界点的预定一侧(如上方)滑动时,获知推钮的移动类型为第一移动类型,监测到推钮向行程分界点的另一侧(如下方)滑动时,获知推钮的移动类型为第二移动类型,并由推钮的滑动距离得到移动量。 Type when the mobile [0043] When implemented by a push button actuator, the stroke dividing point is provided on the push stroke actuator, to monitor a predetermined one side of the push button stroke demarcation point (e.g., the top) slide, known as a first push button a moving type, it is monitored that the other side of the sliding stroke of the push button to the boundary point (the following party), is known to move a second type of movement of the push button type, the push button by sliding distance obtained movement amount. 参见图5,示出了调节器为推钮的示意图,推钮安装在滑动槽中,推钮沿着滑动槽上下滑动。 Referring to Figure 5, there is shown a schematic view of the regulator of the push button, the push button is mounted in a sliding groove, the push button slides up and down along the slide groove.

[0044] 通过两个按键实现调节器时,监测到第一按键被按动时,获知按键的移动类型为第一移动类型,监测到第二按键被按动时,获知按键的移动类型为第二移动类型,并由按键的按动次数得到所述移动量。 [0044] is achieved by adjusting the two buttons, a first button monitored when pressed, moves the button type known as a first type movement, the movement monitor when the button is pressed a second type, known as a first key two types of movement, the number of keys pressed by the obtained movement amount. 参见图6,示出了调节器为按键的示意图,包括可以上下按动的第一按键和第二按键。 Referring to Figure 6, there is shown a schematic diagram of the regulator key, including a first up and down keys and pressing a second key.

[0045] 一个场景下,如果调节器是旋钮的方式,则可以设置旋钮处在中间位置时对外界环境声音不放大也不降低,往左旋转则实现降噪,往左旋转的越多降噪量越大,旋转到最左边的位置降噪量最大;设置旋钮往右旋转为监听到的环境声放大,越往右旋转监听声越大,旋转到最右边的位置则监听声放大达到最大,同样推钮和按键可以实现同样的功能。 [0045] of a scenario, if the regulator is a way knob, the knob may be provided in an intermediate position of the environmental sound without enlargement and reduction, noise reduction is achieved left rotation, left rotation, the more noise reduction the larger the amount of rotation to the leftmost position of the maximum amount of noise reduction; setting knob rotation right to listen to ambient sound amplification, the greater the rotation right sound monitor, rotated to the rightmost position of the listener maximum sound amplification, Also the push button and the button can perform the same function.

[0046] 上述主要以头戴式耳机为例对调节器进行了说明,对于入耳式耳机,调节器设置在线控器上,具体设置方式可以参见头戴式耳机的调节器。 [0046] In the above-described headphone as an example of the main controller has been described, for ear headphones, the regulator is provided on line controller, reference may be specific arrangement headset regulator.

[0048] 如图7所示,示出了降噪模块采用前馈加反馈实现时的混合主动降噪耳机系统框图。 [0048] As shown in FIG. 7 shows the noise reduction module when mixed Feedforward block diagram of a feedback active noise reduction headset system implemented. 其系统最大降噪量和降噪频带为反馈(FB主动降噪控制ANC)和前馈(FF ANC)两方面降噪量的叠加,基本降噪性能参见图7,降噪模块在低频1000Hz都有主动降噪量,最大主动降噪量可达到25db左右,配合耳罩或者耳塞的被动隔声,降噪耳机在整个频带内都能提供差不多20db的降噪效果。 Which is the maximum amount of noise reduction and noise reduction system of the feedback band (FB active noise control ANC) and superposition of noise reduction by both the feedforward (the FF ANC), substantially noise performance Referring to Figure 7, noise reduction module are at a low frequency 1000Hz with active noise reduction, the maximum amount of active noise reduction can reach 25db, with earmuffs or earplugs passive sound insulation, noise reduction headphones can provide almost 20db of noise reduction over the entire frequency band.

[0049] 降噪量/放大量可以通过调整电路或者是软件修改寄存器的形式可以实现不同的降噪级别/监听级别,用户可以根据需要手动进行降噪效果/监听效果的调整。 [0049] The noise reduction / amplification amount by the adjustment circuit or a software modification may be implemented in different registers of the noise reduction level / level monitor, the user can adjust the noise reduction effect / listening effect manually as needed.

[0050] 例如,采用MCU (Micro Control Unit,微控制单元)实现降噪模块和/或监听模块时,如主控芯片为MCU时,利用确认的调节量修改MCU控制MCU寄存器的写入值,来改变降噪量或放大量。 When [0050] For example, using the MCU (Micro Control Unit, a micro control unit) noise reduction module and / or monitoring module, such as when the master chip for the MCU, with an acknowledgment of the modification amount adjustment value written MCU MCU control register, to change the amount or put a lot of noise. 降噪模块或监听模块会置于外界环境噪声中的麦克风(如FF/FB降噪MICl或监听MIC2)拾取到的信号经过一定的EQ(均衡器)放大和补偿,然后输出给耳机扬声器让耳机佩戴者听到。 Noise reduction module or monitor module disposed ambient noise microphone (e.g., FF / FB monitor or noise MICl MIC2) to pick up a signal after a certain EQ (equalizer) for amplification and compensation, and then outputted to the headset earpiece speaker the wearer hear. 通过EQ处理可以实现弱化低频提升中高频的作用,使耳机输出的声音更符合人耳听觉效果。 EQ processing can be achieved by weakening the effect of the low frequency boost of high frequency, the sound output from the headphone more in line with human auditory effect.
