Embodiment Construction

[0020] Embodiments of the present invention will be described below with reference to the accompanying drawings.

[0021] Fig. 1 schematically illustrates an electronic device embodying the invention in the form of a block diagram.

[0022] This electronic device is, for example, a notebook personal computer, and is generally controlled by the CPU 11 . The CPU 11 is connected to a high-speed local bus. The bridge controller 12 provides a bridge function for interconnecting the CPU local bus and the system bus laid out in the device.

[0023] System memory 13 and BIOS-ROM 14 are connected to bridge controller 12 . The bridge controller 12 has a function of controlling access to these components. Registers are configured in the bridge controller, and instructions are received from the outside through the registers.

[0024] The system memory 13 is a storage medium serving as a main memory of the electronic device, and temporarily stores various programs executed by the CPU 1...

Abstract

When power is turned on, a speaker volume control section (141) obtains the volume of surrounding sound from a microphone (191) and then determines the output volume of a speaker (192) from the volume of surrounding sound. The speaker volume control section (141) then displays the value of the output volume of the speaker (192) thus determined on an LCD (15). After that, the speaker volume control section (141) monitors whether or not an operation of changing the speaker volume is performed and, when such an operation is not performed for a predetermined period of time, presents the determined speaker volume to a sound controller (19). When an operation of changing the speaker volume is performed, the speaker volume control section (141) presents a volume specified by the user to the sound controller (19).

Description

technical field [0001] The present invention relates to a technique of controlling the output volume of a speaker used in an electronic device such as a personal computer. Background technique [0002] In recent years, battery-powered and portable electronic devices such as notebook computers and personal digital assistant (PDA) terminals have been widely used. Many kinds of these electronic devices are equipped with sound functions, including a sound input function using a microphone and a sound output function using a speaker, allowing users to record simple voice memos and listen to music. [0003] Since such electronic devices are made to be easily portable, it is very possible for users to use them wherever they go or on the move. That said, depending on the time of day and surroundings, it's not an exceptional thing to use such an electronic device in a quiet environment or in a noisy environment. Meanwhile, the speaker volume used in the sound function is usually ad...
