Abstract

PURPOSE:To produce always optimum buzzer sounds by determining the properties of the buzzer sounds generated according to ambient noise levels and the importance degree of warning contents. CONSTITUTION:This device has a noise sensor 11 which measures the ambient noise level of a personal computer 10, a buzzer sound table 12 in which the magnitude and pitch of the sounds corresponding to the noise levels and the importance degree of the warning contents are stored and a buzzer sound generating mechanism 13 which produces the buzzer sounds of the magnitude and pitch corresponding to the information from the buzzer sound table 12. The properties of the buzzer sounds to be generated are determined from the noise levels and the importance degree of the warning contents in the buzzer sound table 12. The noise level is set as the ambient noises are lower and the sound level is set larger as the ambient noises are larger. The sound level is set larger as the importance degree of the warning contents is higher.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a buzzer sound generation method for generating a buzzer sound when issuing a warning to an operator of a personal computer or the like.

[Conventional technology]

Conventionally, the buzzer sound of personal computers has been adjusted using a volume knob, or the pitch of the sound has been determined by software commands depending on the content of the warning.

[Problem to be solved by the invention]

In the conventional buzzer sound generation method described above, when the volume is set to low and the surroundings are noisy, the buzzer sound is difficult to hear. On the other hand, if the volume is turned up when the surroundings are quiet, the buzzer sound may become unusually loud and unpleasant.

Further, it is time-consuming to change settings using a volume knob or the like according to changes in noise, and the user is unlikely to notice changes in noise.

[Means to solve the problem]

In the buzzer sound generation method according to the present invention, the nature of the generated buzzer sound is determined depending on the surrounding noise level and the importance of the content of the warning.

〔Example〕

Next, an embodiment of the present invention will be described in more detail with reference to the drawings.

FIG. 1 is a block diagram of one embodiment of the present invention. In this embodiment, the nature of the buzzer sound (loudness and pitch) is determined based on the ambient noise level and the importance of the warning content. For this reason, the present embodiment includes a noise sensor 11 that measures the noise level around the personal computer 10, and a buzzer sound table 12 that stores the loudness and pitch of the sound according to the noise level and the importance of the warning content.
and a buzzer sound generating mechanism 13 that generates a buzzer sound of a size and height according to information from the buzzer sound table 12.

In the buzzer sound table 12, as shown in FIG. 2, the nature of the buzzer sound to be generated is determined based on the noise level and the importance of the warning content. The quieter the surrounding noise, the smaller the number of noise levels, and the louder the noise, the larger the number of noise levels.

The more important the warning content is, the larger the number is. A□
In □, if m is small, the volume is low, and if m is large, the volume is high.

If n is small, a low tone will be generated, and if n is large, a high tone will be generated.

If this table is used to determine the nature of the buzzer sound, the noisier the surroundings, the louder the volume, and the more important the warning, the higher the sound.

〔Effect of the invention〕

As explained above, the present invention enables the optimum buzzer sound to always sound by determining the characteristics of the generated buzzer sound based on information about the ambient noise level and the importance of the warning when the buzzer sound is generated. There is an effect that it can be done.
