### 特征比对表格

技术特征描述及公开性判断结果对比文件原文引用公开性论述
**A:** 其包括:经由所述移动装置的一个或多个传感器动态检测所述移动装置的相对于邻近所述移动装置的一个或多个物理对象的放置,其中所述移动装置包含扬声器<br>**《直接公开》**[0024] “device 10 includes a housing 11 with a speaker port 12, a speaker 9 mounted within the housing, four touch sensors 13A, 13B, 13C, and 13D (collectively or individually sensors 13)...”<br>[0029] “When a user wishing to listen to acoustic output from the device 10 (e.g. upon receipt of a telephone call) places the device 10 against his or her ear 30, the speaker port 12 will be aligned, more or less, with the ear. ... This is detected (S501) at the microprocessor 21 (FIG. 2), e.g., in the form of one or more interrupts generated in response to sensor activation.”<br>[0030] “Responsive to the detection of touch contact between the ear 30 and at least one of the sensors 13, the microprocessor engages in processing for estimating the degree of seal of the ear about the speaker port (S502, FIG. 5).”对比文件明确公开了电子设备(即移动装置的一种)包含扬声器(speaker 9)。该设备通过至少一个触摸传感器(touch sensors 13)动态检测用户的耳朵(即邻近移动装置的一个物理对象)与设备扬声器端口(speaker port 12)的接触位置和/或面积,并基于此估计耳朵对端口的密封程度。这个“密封程度”直接反映了设备相对于用户耳朵的放置状态(例如,是紧密贴合还是存在缝隙)。因此,对比文件公开了通过传感器动态检测移动装置相对于邻近物理对象(用户耳朵)的放置。
**B:** 根据所述移动装置的所述放置执行所述移动装置的扬声器均衡,<br>**《直接公开》**[0032] “Based on fact that the degree of seal is estimated to be high, the acoustic output of speaker 9 is adjusted by attenuating low frequencies (S504, FIG. 5), e.g., between 300 Hz and 1 KHz. This has the result of improving the quality of the sound perceived by the user, as the overall audio response perceived by the user will be equalized to a flat response...”<br>[0034] “Based on fact that the degree of seal is estimated to be low, the acoustic output of speaker 9 is adjusted by amplifying low frequencies (S506), e.g., between 300 Hz and 1 KHz. This similarly has the result of improving the quality of the sound perceived by the user, again because the overall audio response perceived by the user will be equalized to a flat response.”对比文件公开了根据估计的密封程度(即所确定的设备相对于耳朵的放置状态)来调整扬声器的声学输出。具体地,当密封程度高(High)时衰减低频,密封程度低(Low)时放大低频,目的是使用户感知的音频响应均衡到平坦响应(equalized to a flat response)。这种基于放置状态对特定频率范围进行补偿性调整,正是“扬声器均衡(speaker equalization)”的体现。因此,该技术特征被直接公开。
**C:** 其中所述移动装置的所述放置包括以下各项中的至少一者:所述移动装置以扬声器面向下放置在表面上,其中所述扬声器至少部分地被阻挡<br>**《未公开》**无相关内容。对比文件全文描述的都是设备被手持并贴近耳朵使用的场景,通过触摸传感器检测耳朵的接触来估计密封程度。没有提及移动装置被放置在诸如桌子等表面上,也没有涉及扬声器因面向下放置而被表面阻挡的情形。因此,该特定放置方式未被公开。
**D:** 所述移动装置以扬声器面向上放置在表面上,其中所述扬声器不受阻挡<br>**《未公开》**无相关内容。同上,对比文件未描述移动装置被放置在表面上且扬声器面向上不受阻挡的场景。其应用场景仅限于手持通话。
**E:** 所述移动装置由用户保持,其中所述扬声器不受阻挡<br>**《隐含公开》**[0002] “When using such an electronic device, a user may need to situate the speaker port near his or her ear so as to be able to hear the acoustic output. There are many different orientations in which the user may hold the device near his or her ear.”<br>[0034] 描述了“low degree of seal”(低密封度)的情况,例如图4所示,耳朵仅接触扬声器端口一侧的传感器(例如只有13D被激活),这意味着扬声器端口并未被耳朵紧密包围,声学上更开放,即扬声器相对“不受阻挡”。对比文件明确描述了用户手持设备并将其靠近耳朵使用的多种不同取向(user may hold the device)。这是“移动装置由用户保持”的典型场景。同时,对比文件定义了“低密封度(low degree of seal)”状态,在此状态下,耳朵仅部分接触设备(如图4所示,仅激活一个传感器),扬声器端口并未被完全密封,声学负载较小,实质上可以认为扬声器在这种放置状态下“不受阻挡”(相对于高密封度状态)。因此,本领域技术人员可以从对比文件公开的用户手持设备以及低密封度状态,合理推断出“移动装置由用户保持,其中扬声器不受阻挡”这一技术方案。
**F:** 所述移动装置保持在隐蔽位置中,其中所述扬声器至少部分地被阻挡<br>**《未公开》**无相关内容。对比文件未提及移动装置被放置在口袋、包、保护壳等“隐蔽位置”中的情形。其检测机制依赖于触摸传感器与用户耳朵的直接接触,无法应用于被其他物体遮挡的场景。
**G:** 各项的各种组合。<br>**《未公开》**无相关内容。特征G是对特征C-F所述特定放置方式的组合引用。由于特征C、D、F均未被对比文件公开,特征E为隐含公开,因此这些特定放置方式的“各种组合”在对比文件中没有依据。
**H:** 其中执行扬声器均衡进一步包括:至少部分基于所述移动装置的所述放置而识别预定扬声器均衡配置<br>**《直接公开》**[0032] “Based on fact that the degree of seal is estimated to be high, the acoustic output of speaker 9 is adjusted by attenuating low frequencies (S504, FIG. 5)...”<br>[0034] “Based on fact that the degree of seal is estimated to be low, the acoustic output of speaker 9 is adjusted by amplifying low frequencies (S506)...”<br>[0059] “operating system software 27 may also incorporate models dictating how the acoustic output should be modified to compensate for a detected degree of seal.”对比文件公开了基于估计的密封程度(即放置状态)来选择相应的声学输出调整策略:高密封度对应衰减低频的配置,低密封度对应放大低频的配置。这相当于至少部分基于放置(密封程度)识别了预定的均衡处理配置(衰减或放大特定频段)。说明书[0059]段进一步提到操作系统软件可包含规定如何修改声学输出以补偿检测到的密封程度的“模型(models)”,这些模型本质上就是预定的均衡配置。
**I:** 根据所述预定扬声器均衡配置调整所述移动装置的所述扬声器输出的频率范围。<br>**《直接公开》**[0032] “...the acoustic output of speaker 9 is adjusted by attenuating low frequencies (S504, FIG. 5), e.g., between 300 Hz and 1 KHz.”<br>[0034] “...the acoustic output of speaker 9 is adjusted by amplifying low frequencies (S506), e.g., between 300 Hz and 1 KHz.”<br>[0061] “For example, a band pass filter may be used if it is desired that frequencies within a certain range (such as high frequencies) be output while frequencies outside that range (such as low frequencies) be attenuated.”对比文件明确记载了根据识别出的配置(高密封度衰减低频,低密封度放大低频)来调整扬声器输出的频率范围(例如,300 Hz至1 KHz的低频)。[0061]段还提及可使用带通滤波器等来调整特定频率范围。这直接公开了根据预定配置调整扬声器输出的频率范围。
**J:** 其中所述移动装置的所述放置至少部分地阻挡所述扬声器。<br>**《直接公开》**[0002] “...the user may press the speaker port against his or her ear such that his ear substantially surrounds the speaker port. In that case, the speaker plays into a small contained volume of air within the ear cavity. This is known as a sealed condition or as a "high degree of seal".”<br>[0031] 描述了高密封度的情况,即两个相对的传感器同时被激活(如图3所示),这意味着耳朵紧密包围了扬声器端口,形成了密封。对比文件详细描述了“高密封度(high degree of seal)”状态,即用户将耳朵紧压在扬声器端口上,使其被耳朵基本包围。在这种状态下,扬声器在一个小的封闭空腔(耳道)中播放,扬声器端口被耳朵物理遮挡和密封,这实质上构成了“至少部分地阻挡所述扬声器”。该技术特征被直接公开。
**K:** 其中所述移动装置的所述放置移除对所述扬声器的阻挡。<br>**《隐含公开》**[0002] “Alternatively, the user may only touch part of his ear to the speaker port such that the speaker is substantially open to the environment. In that case, the speaker plays into a much larger volume of air. This is known as a leak condition or as a "low degree of seal".”<br>[0034] 描述了低密封度(泄漏条件)的情况,例如图4所示,耳朵仅接触一个传感器,扬声器基本向环境开放。对比文件公开了“低密封度(low degree of seal)”或“泄漏条件(leak condition)”,即用户耳朵仅部分接触扬声器端口,使得扬声器基本向环境开放。相对于“高密封度”下扬声器被耳朵阻挡的状态,这种“泄漏条件”意味着对扬声器端口/扬声器的阻挡被移除或不存在,扬声器可以更自由地向外部空间辐射声音。本领域技术人员可以合理推断,当设备处于这种未被紧密密封的放置状态时,即移除了(或不存在)对扬声器的阻挡。因此,该技术特征被隐含公开。
**L:** 其中动态检测所述移动装置的所述放置进一步包括基于来自以下各项中的至少一者的数据推断所述放置:相机、环境光传感器、加速度计、磁力计、陀螺仪、气压传感器、全球定位传感器和WiFi传感器。<br>**《未公开》**[0024] “...four touch sensors 13A, 13B, 13C, and 13D...”<br>[0029]-[0030] 描述了通过触摸传感器检测耳朵接触并估计密封程度。对比文件用于检测放置(密封程度)的传感器明确且仅限于触摸传感器(touch sensors)。虽然说明书提到了触摸屏传感器(如图6、7等),但其本质仍是检测接触的触摸传感器。对比文件完全没有提及使用目标专利权利要求L中列举的相机、环境光传感器、加速度计、磁力计、陀螺仪、气压传感器、全球定位传感器或WiFi传感器中的任何一种来推断放置。因此,该技术特征未被公开。
