Problems solved by technology

However, in some environments, the output audio signal cannot be heard clearly even with the volume turned up to the maximum due to the background noise
In addition to increasing the sound amplitude, the power output must also be increased at the same time, which will increase the power consumption
And letting the speaker output sound with high power for a long time will also shorten the life of the speaker

Embodiment Construction

[0039] The preferred embodiments of the present invention and their effects will be described in conjunction with the accompanying drawings as follows.

[0040] Please refer to FIG. 1 , which is a schematic diagram of the first embodiment of the present invention. The device for adjusting prompt sound according to the environment of the present invention includes: a receiving module 10 , an analyzing module 20 and an output module 30 .

[0041] Any portable electronic device that has the function of outputting the prompt sound can use the device for adjusting the prompt sound proposed by the present invention. Since the portable electronic device will have different background sounds depending on the user's environment. Therefore, the background sound is firstly received by the receiving module 10, so that the device of the present invention can acquire information about the background sound of the current environment for subsequent processing.

[0042] The analyzing module ...

Abstract

The invention discloses a device for adjusting an indicated sound according to environments and a method. The device for adjusting the indicated sound according to environments comprises a receiving module, an analyzing module and an output module, wherein, the receiving module is used for receiving a background sound; the analyzing module generates a control signal according to the background sound; the output module adjusts the output frequency of the indicated sound through the control signal and outputs the indicated sound which is adjusted. By adopting the device and the method, the vibration amplitude of the indicated sound can be kept to be unchangeable, so the consumed power of a portable electronic device does not need to be added; in this way, a loudspeaker which outputs the indicated sound can keep the same power, and the damage of the loudspeaker caused by the high power is avoided, thereby prolonging the service life of the loudspeaker.

Description

technical field [0001] The present invention relates to a device and method for adjusting the prompt sound, in particular to a device and method for adjusting the prompt sound according to the environment. Background technique [0002] Generally, portable electronic devices with sound output function, such as mobile phones, personal digital assistants (PDAs), global positioning systems (GPS), etc., must manually set the output of the sound volume. As the ambient background volume changes, the user must manually adjust the output volume of the portable electronic device to clearly hear the output sound under different environmental conditions. In this way, it will cause inconvenience to users in use. [0003] Therefore, China Taiwan's patent application No. 93125950 "Volume Control Device and Method", mainly introduces when the external environment transmits an interfering audio source signal, by analyzing the relationship between the interfering audio source signal in the e...
