The media player 102 includes a media player internal power supply 302 arranged to store energy used to power to media player 110 before (i.e., booting up) and during playback of In another embodiment, a consumer electronic product operable in a DC mode and an AC mode is described that includes a portable media player arranged to playback a selected one of

The processor 308 responds to the volume clipping signal VCL, by decreasing the maximum available sound pressure level of the speakers 118 by a SPL reduction factor ASPL (see FIG. 5). FIG. 10 shows a process 1000 for monitoring the charge status of the internal power supply in accordance with an embodiment of the invention. In one implementation, the media player 200 is a handheld device that is sized for placement into a pocket or hand of the user. Is it the same as the laptop?

The method of claim 1 further comprising determining if a power cable is connected to an external power supply. 14. The housing 104 also includes volume control devices 120 and 122.

This notification is communicated by the monitor 309 to the processor 308 by way of a volume clipping signal VCL. The speaker 214 can be a speaker internal to the media player 200 or external to the media player 200. At 1102 a determination is made whether or not there is an imminent loss of power expected. FIG. 7 illustrates a causal relationship between the period of time of useful operation of the consumer electronic product 300 and the actual output SPL of the speakers 118.

The computer readable medium of claim 14 wherein the method further comprises determining that the residual power is exhausted. It should be noted that this determination can be accomplished in any number of ways. FIG. 8 shows a flowchart detailing a process 800 in accordance with an embodiment of the invention.

Although the portable media player 110 is fully operational apart from the media delivery accessory 102, the portable media player 110 can be connected to the media delivery accessory 104. Not all USB-C ports are configured to receive power, or even the same amount of power.The right profile your USB-C device dictated by your device and can not be adjusted. It is not surprising when the actual output SPL is reduced (and the charge drain from the internal power supply 310 is concomitantly reduced), the length of time t7 that the For example, the user of the remote controller 128 can interact with the user input controls 130 to select a media item to be played on the portable media player 110

Computer program product executable by a processor for shutting down a consumer electronic product so as to avoid generation of audio artifacts is also described that includes computer code for determining click site While this invention has been described in terms of a preferred embodiment, there are alterations, permutations, and equivalents that fall within the scope of this invention. Holdings, Ltd.Hand-held portable computer having capability for external expansion of an internal busUS5583993Jan 31, 1994Dec 10, 1996Apple Computer, Inc.Method and apparatus for synchronously sharing data among computerUS5602455Nov 4, 1994Feb 11, 1997Hewlett-Packard In this case, there remains the possibility that a user would notice a reduced perceived volume of any audio from the speakers 118.

The cache 206 is, for example, Random-Access Memory (RAM) provided by semiconductor memory. For example, the media player 200 can be a media player (e.g., MP3 player), a game player, a remote controller, a portable communication device, and the like. In this way, the energy used to drive the speakers (which is ultimately provided by energy stored in the internal power supply) is reflected in the dynamic characteristics of the capacitor The process 800 begins at 802 by determining if the media player is connected to the media delivery accessory.

In one embodiment, the maximum allowable SPL is based upon an amount of stored energy available in the limited capacity DC power source. In a particularly useful embodiment, the power port 316 includes a power cable sensor 318 that reacts to a power cable connect/disconnect event by sending a power cable status signal 320 FIG. 11 shows a flowchart detailing a process 1100 for gently shutting down the consumer product in accordance with an embodiment of the invention.

For example, the user input device 208 can take a variety of forms, such as a button, keypad, dial, etc.

Additionally, keep in mind not to publicly post personal information (serial numbers and case details). Although the media items of emphasis in several of the above embodiments where audio items (e.g., audio files or songs), the media items are not limited to audio items. Not exhaustive. In order to quantify this reduction in SPL, the monitor 309 tracks the capacitor voltage Vc (typically in a range of 200-300 volts) in real time (as in FIG. 4A) and

application Ser. In one embodiment, the speakers 118 include a pair of midrange speakers and a subwoofer speaker. As the charge stored in the internal power supply 310 decreases with usage over time, every subsequent volume clipping event causes the processor 308 to reduce the maximum allowable SPL by More about the author The remote controller 128 can also be used to alter the volume of the audio output from the media delivery accessory 102.

For example, headphones or earphones that connect to the media player 200 would be considered an external speaker. On the other hand, if the power cable is not connected to the external power supply (DC mode), then at 908 a maximum allowable sound pressure level (SPL) for the speakers Try switching the power adapters and see if it clears up the problem with the dock.
