目标专利名称:340用于移动装置的扬声器均衡CN104956688B

本次调用的模型名称:GPT-4

根据目标专利说明书,本发明涉及一种用于移动装置的扬声器均衡技术,其核心在于:通过移动装置的一个或多个传感器(如相机、环境光传感器、加速度计等)动态检测移动装置相对于邻近物理对象(如表面、用户的手)的放置状态(例如,扬声器面向下/面向上放置在表面、手持、在隐蔽位置等),并根据该放置状态来执行扬声器均衡。均衡过程包括基于放置识别预定的均衡配置,并据此调整扬声器输出的频率范围。其目的是为了补偿因装置放置不同(导致扬声器被阻挡或解除阻挡)而引起的音频性能变化。

对比文件涉及一种通信设备(如蜂窝电话)中的主动均衡电路和方法,其核心在于:通过位于听筒(earpiece)附近的传感器(如麦克风)测量听筒处的声压(acoustic pressure),并根据该测量结果动态调整均衡滤波器的响应和增益,以维持恒定的频率响应和音量水平,不受听筒与用户耳朵之间声学耦合(如紧密贴合、低泄漏、高泄漏)变化的影响。其目的是解决因设备与耳朵的贴合程度不同导致的音质变化问题,提升通话舒适度。

以下是根据目标专利权利要求划分的技术特征与对比文件的比对分析:

### 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
**技术特征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>**判断结果:《隐含公开》**“The sensor 20 measures the audio response related to the acoustic pressure at the earpiece 14.” (第2栏第51-53行)<br>“One of ordinary skill in the art will recognize that the acoustic pressure 61 varies as the communication device 10 is brought closer or farther away from the ear of the user of the communication device 10.” (第3栏第1-4行)<br>“The adaptation circuit 46 of the digital signal processor 26 uses the response data signal 62 ... to determine how the adjustment signal 48 is to be updated ... This process continues with the adjustable equalization filter 44 being regularly updated to take into account any changes in how the user is holding the communication device 10 to their ear.” (第3栏第26-33行)对比文件公开了通信设备(即移动装置)包含扬声器(speaker 55, 参见第2栏第65行-第3栏第1行)。其使用传感器20(例如麦克风)动态测量听筒(earpiece)处的声压(acoustic pressure),该声压会随着设备被用户拿得更靠近或远离耳朵而变化。这种测量本质上是在动态检测设备与一个邻近物理对象(即用户的耳朵/头部)之间的相对位置关系(即声学耦合状态)。虽然对比文件未明确使用“放置(placement)”一词,也未提及检测相对于桌面、手掌等其他物理对象的放置,但“用户如何握持设备到耳朵(how the user is holding the communication device to their ear)”这一描述,已经隐含了设备相对于用户耳朵这一特定物理对象的相对位置和姿态的动态检测。因此,本领域技术人员可以从对比文件公开的“通过传感器测量声压变化以感知设备与耳朵的耦合情况”这一技术手段中,合理推断出其公开了“经由传感器动态检测移动装置相对于一个邻近物理对象(用户耳朵)的放置”这一技术特征。
**技术特征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>**判断结果:《直接公开》**“An active equalization circuit (not shown—see FIG. 4) is preferably coupled to the sensor 20 for equalizing the audio response at the earpiece 14.” (第2栏第53-56行)<br>“The adaptation circuit 46 ... provides information for adjustment of the filter response and gain via an adjustment signal 48.” (第2栏第66行-第3栏第3行)<br>“Once filtered via the adjustable equalization filter 44, the filtered audio signal 50 is processed by the output audio processing block 28; and a processed output audio signal 53 is sent to a speaker 55.” (第3栏第1-4行)<br>“The process as illustrated and described in FIG. 6 provides a method ... measuring the acoustic pressure 61 at the earpiece 14; adjusting the filter response using the measured acoustic pressure 61 ... and transmitting the second filtered audio signal through the earpiece 14.” (第4栏第16-24行)对比文件明确公开了根据传感器20测量的声压(即反映设备与耳朵的耦合状态,等同于一种特定的“放置”状态)来调整均衡滤波器(adjustable equalization filter 44)的响应和增益,从而对传输到扬声器(speaker 55)/听筒(earpiece 14)的音频信号进行均衡处理。这直接对应于目标专利中“根据移动装置的放置执行扬声器均衡”的技术特征。两者的作用均是依据设备所处的物理状态(耦合/放置)来调整音频输出特性。
**技术特征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>**判断结果:《未公开》**对比文件全文未提及移动装置(通信设备)被放置在桌面、台面等任何表面上,也未提及扬声器/听筒因面向下放置而被表面阻挡的场景。其所有实施例均围绕设备与用户耳朵的声学耦合展开。对比文件仅涉及通信设备被手持并贴近耳朵使用的场景。其中描述的声学耦合变化(密封、低泄漏、高泄漏)是由于设备与耳朵的贴合程度不同引起的,并非由于设备被放置于表面上且扬声器被表面阻挡所导致。本领域技术人员无法从对比文件公开的内容中直接或隐含地得出“移动装置以扬声器面向下放置在表面上”这一具体放置状态。
**技术特征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>**判断结果:《未公开》**对比文件全文未提及移动装置(通信设备)被放置在桌面、台面等任何表面上,也未提及扬声器/听筒面向上放置且不受阻挡的场景。同上,对比文件的技术场景局限于手持通话。其中没有描述设备被静置在表面上(无论扬声器面向上或向下)的任何情形,更未涉及此种状态下扬声器是否受阻挡。因此,该特征未被公开。
**技术特征E**:所述移动装置由用户保持,其中所述扬声器不受阻挡<br>**判断结果:《未公开》**“The user can press the earpiece firmly to their ear, and then pull it away and still hear the audio...” (第5栏第4-6行)<br>“... the user no longer has to firmly press the communication device to their ear, but can lightly rest it against their ear, or hold it so that it’s not even touching it.” (第5栏第6-9行)对比文件公开了用户手持(hold)通信设备并将其置于耳朵旁的场景。然而,在所述场景中,听筒/扬声器始终朝向并靠近用户的耳朵。根据声学原理,当设备紧贴耳朵时(“sealed ear”),听筒出口实际上被耳朵和头部部分遮挡;当设备稍微离开耳朵时(“low leak”或“high leak”),虽然存在间隙,但扬声器声波仍然主要指向耳朵区域,而非完全自由的“不受阻挡”状态。目标专利中“由用户保持,其中所述扬声器不受阻挡”可能指手持但扬声器未受手或表面遮挡(例如手持手机播放媒体时扬声器朝外),这与对比文件中专注于听筒-耳朵耦合、扬声器始终正对/靠近耳朵(因而存在声学负载,可视为一种声学上的“阻挡”或“耦合”)的场景存在本质区别。因此,对比文件未公开“扬声器不受阻挡”这一限定条件下的用户手持状态。
**技术特征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>**判断结果:《未公开》**对比文件全文未提及移动装置被放置在口袋、保护套等“隐蔽位置”中。对比文件的技术方案聚焦于在使用状态下(即通话或听音时)通过传感器动态调整均衡。它没有涉及设备被收纳在口袋、包或保护壳等隐蔽位置(此时通常未在使用)的场景。因此,该特征未被公开。
**技术特征G**:各项的各种组合。<br>**判断结果:《未公开》**由于技术特征C、D、E、F均未在对比文件中被公开,因此它们的“各种组合”这一上位概念也未被公开。技术特征G是技术特征C-F的概括性组合。由于对比文件未公开其中任何一个具体的放置状态(面向下、面向上、手持且扬声器不受阻挡、隐蔽位置),因此本领域技术人员无法从对比文件中得出这些具体放置状态的任何组合。
**技术特征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>**判断结果:《隐含公开》**“Next, in Step 66, the filter response of the adjustable equalization filter 44 is set to a preset filter response. The preset filter response may be hard coded or programmed into the digital signal processor 26 during manufacturing, may be programmed over-the-air into the digital signal processor 26 or may be a manually set value.” (第3栏第58行-第4栏第2行)<br>“The adaptation circuit 46 ... provides information for adjustment of the filter response and gain via an adjustment signal 48.” (第2栏第66行-第3栏第3行)<br>“The adaptation circuit 46 ... uses the response data signal 62 along with the digital input signal 42 to determine how the adjustment signal 48 is to be updated to achieve the desired frequency responses of the adjustable equalization filter 44.” (第3栏第26-30行)对比文件公开了均衡滤波器具有一个“预设的(preset)”滤波器响应(步骤66),这相当于一个预定的初始或基础均衡配置。更重要的是,其“自适应电路(adaptation circuit 46)”根据传感器测量的声压(即设备与耳朵的耦合状态,一种特定的“放置”)来确定如何更新调整信号,以使得均衡滤波器达到“期望的频率响应(desired frequency responses)”。这里的“期望的频率响应”可以理解为对应于不同耦合状态(不同放置)的一系列目标均衡配置。虽然对比文件没有明确使用“识别(identify)”一词,也没有一个存储了多种“预定配置”的数据库供查询,但其自适应电路根据实时检测到的状态(放置)来动态计算并应用相应的滤波器参数,以实现期望的音频响应,这在功能上等同于“至少部分基于移动装置的放置而识别(即确定或选择)一个预定扬声器均衡配置(即期望的频率响应)”。因此,该特征被对比文件隐含公开。
**技术特征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>**判断结果:《直接公开》**“The digital signal processor 26 receives the digital input signal 42 and filters the digital input signal 42 via an adjustable equalization filter 44. The adjustable equalization filter 44 operates using an adjustable filter response and gain.” (第2栏第60-64行)<br>“The adaptation circuit 46 ... provides information for adjustment of the filter response and gain via an adjustment signal 48.” (第2栏第66行-第3栏第3行)<br>“The process results in a frequency response, which is typically flat across the frequency range of interest (i.e.: 300-3400 Hz)...” (第3栏第30-32行)对比文件直接且明确地公开了根据调整信号(其承载了基于传感器测量结果确定的调整信息,即对应于一种“预定”的均衡目标)来调整可调均衡滤波器(adjustable equalization filter 44)的响应和增益,从而改变输出到扬声器(speaker 55)的音频信号的频率响应(例如使其在300-3400Hz范围内平坦)。这直接对应于“根据预定扬声器均衡配置调整扬声器输出的频率范围”。
**技术特征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>**判断结果:《隐含公开》**“One drawback to traditional communication devices is that the experienced volume level and frequency spectrum of the acoustic output signal varies as the acoustical impedance loading of the communication device to a person's ear varies. The acoustical impedance loading is related to the volume of space, as well as any leakage paths, between the communication device and the listener's ear. As the coupling of the communication device to the ear changes, the impedance loading changes.” (第1栏第37-44行)<br>“FIG. 1 illustrates the frequency response of three simulated acoustical loadings of the listener's ear: a sealed ear, a low leak simulator, and a high leak simulator.” (第1栏第44-47行)对比文件明确指出,传统设备的一个缺点是,当设备与人耳之间的声学阻抗负载(与两者之间的空间容积和泄漏路径有关)变化时,音频输出信号的频谱会变化。它模拟了三种负载情况:密封的耳朵、低泄漏和高泄漏。其中“密封的耳朵(sealed ear)”模拟了设备听筒/扬声器出口被耳朵紧密贴合、几乎完全“阻挡”的状态;“低泄漏(low leak)”和“高泄漏(high leak)”则模拟了不同程度的“部分阻挡”或“遮挡减弱”状态。这些状态的变化是由于用户手持设备并使其与耳朵接触的“放置”方式不同导致的。因此,对比文件隐含公开了移动装置(通信设备)的特定放置(紧贴耳朵)会至少部分地阻挡扬声器(听筒)这一技术特征。
**技术特征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>**判断结果:《隐含公开》**“The user can press the earpiece firmly to their ear, and then pull it away and still hear the audio...” (第5栏第4-6行)<br>“... the user no longer has to firmly press the communication device to their ear, but can lightly rest it against their ear, or hold it so that it’s not even touching it.” (第5栏第6-9行)对比文件描述了用户可以将听筒紧紧按压在耳朵上,然后将其拉开。当用户将设备从耳朵上“拉开(pull it away)”或“甚至不接触(not even touching it)”时,相对于“紧密按压(firmly press)”的状态,对听筒/扬声器的声学阻挡(即密封)被移除了,形成了“低泄漏”或“高泄漏”状态。这种状态的变化是由用户改变设备持握位置(即“放置”)所导致的。因此,本领域技术人员可以合理推断,对比文件隐含公开了通过改变移动装置的放置(从紧贴耳朵变为离开耳朵)可以移除对扬声器的阻挡。
**技术特征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>**判断结果:《未公开》**“The sensor 20 measures the audio response related to the acoustic pressure at the earpiece 14.” (第2栏第51-53行)<br>“The sensor 20, for example, can be a microphone proximately located at the earpiece 14 of the communication device 10...” (第3栏第16-18行)对比文件仅公开了使用一种特定的传感器——用于测量声压的传感器(例如麦克风)来检测设备与耳朵的耦合状态。它完全没有提及或暗示使用相机、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设备的放置。其技术方案完全依赖于声学反馈原理,与目标专利中利用多种非声学传感器进行情境感知和放置推断的技术路径不同。因此,该特征未被公开。
