摘要： Disclosed are passive acoustic structures, portable audio devices configured for use with the passive acoustic structures and methods for enhancing the frequency output of a speaker of a portable device configured for use with a disclosed passive acoustic structure. The disclosed portable audio device may include an opening proximal a speaker cavity of the device, a shutter or door to open and close the opening so that the device interoperates with a docking station of a passive acoustic structure including a labyrinth or a transmission line system that may increase the frequency range of the system. For an end user to experience the music and multimedia features of a portable audio device, and in particular a mobile communication device, the above-described passive acoustic structure may provide a bass enhancement for the typically small loudspeaker of a portable audio device with no additional loudspeaker and therefore no additional circuitry.

摘要： Disclosed herein are a plurality of displays for an electronic device including a display layer (102, 104), a light guide layer (108), and a damping material layer (110) coupled between the light guide layer and the display layer. The display layer in one embodiment is a liquid crystal display layer, but other types of display layers may be used. The light guide layer may serve as a back light for the display layer, and may be between approximately 0.05 mm and 2 mm in thickness. Devices described herein include at least one interposed layer of acoustic and/or mechanical energy absorbing material, also referred to herein as damping material, between the display layer susceptible to vibration, and a hard layer near the display layer. The damping material as described herein may reduce the audio noise. The energy absorbing layer may take the form of an audio energy absorbing sheet interposed between layers of the display.

摘要： A power savings mode for data updates is provided. The power savings mode prevents data updates to occur while a screen of a portable electronic device is turned off and the device is in a sleep state. The power savings mode waits until the screen is turned on and the portable electronic device is in a wake state before allowing applications and widgets to update data from network repositories. By preventing applications and widgets from updating data while the portable electronic device is in a sleep state, the power savings mode conserves battery life and network bandwidth by limiting possibly unnecessary data transmissions.
摘要翻译：提供了数据更新的省电模式。省电模式防止在便携式电子设备的屏幕被关闭并且设备处于睡眠状态时发生数据更新。在允许应用程序和小部件从网络存储库更新数据之前，省电模式等待直到屏幕打开并且便携式电子设备处于唤醒状态。通过在便携式电子设备处于睡眠状态时防止应用和小部件更新数据，节电模式通过限制可能不必要的数据传输来节省电池寿命和网络带宽。

摘要： A system and method for removing time division multiple access (TDMA) noise from an audio signal during a silence interval and not during a non-silence interval. An audio silence interval may be a set of frames which have substantially no audible sound (i.e. no speech or voice are audible). This may be determined by analyzing the decibel level or magnitude of the audio signal. In one embodiment, a voice activity detector determines a silence interval within the audio signal and sends a control signal to enable a TDMA noise filter. The audio signal is continuously passed through the TDMA noise filter. However, the TDMA noise filter only operates/processes the silence intervals of the audio signal as a result of the TDMA noise filter being activated by the voice activity detector.
摘要翻译：一种用于在静默间隔期间而不是在非静默间隔期间从音频信号中去除时分多址（TDMA）噪声的系统和方法。音频静音间隔可以是基本上没有可听见的声音（即，没有语音或声音可听见）的一组帧。这可以通过分析音频信号的分贝级别或幅度来确定。在一个实施例中，语音活动检测器确定音频信号内的静音间隔，并发送控制信号以启用TDMA噪声滤波器。音频信号连续通过TDMA噪声滤波器。然而，作为TDMA噪声滤波器由语音活动检测器激活的结果，TDMA噪声滤波器仅操作/处理音频信号的静音间隔。

摘要： A communications device is configured to control the intelligibility of speech in a downlink voice signal during a call. The device determines a current noise level based on sampling ambient acoustic noise and based on a previously determined noise level. The device then determines an overall output gain and a frequency response based on the current noise level and based on a user-selected volume setting of the device. The device modifies the downlink voice signal during the call in accordance with the determined overall output gain and the determined frequency response. Other embodiments are also described and claimed.

摘要： A mobile communications device contains at least two microphones. One microphone is designated by a selector to provide a voice dominant signal and another microphone is designated to provide a noise or echo dominant signal, for a call or a recording. The selector communicates the designations to a switch that routes the selected microphone signals to the inputs of a processor for voice signal enhancement. The selected voice dominant signal is then enhanced by suppressing ambient noise or canceling echo therein, based on the selected noise or echo dominant signal. The designation of microphones may change at any instant during the call or recording depending on various factors, e.g. based on the quality of the microphone signals. Other embodiments are also described.
