Embodiment Construction

[0013] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0014] Such as figure 1 As shown, the earphone device with automatic volume control function of the present invention includes: a microphone, an environmental sound analysis module, a volume control module, and an earphone speaker. Among them, the microphone is used to collect ambient sound; the collected ambient sound signal is sent to the ambient sound analysis module for processing, and the current ambient sound is compared with the ambient sound when the user adjusted the volume last time to judge the change of the ambient sound. Thereby it is determined whether the volume of the earphone output should be changed; the analysis result of the ambient sound analysis module is sent to the volume control module to adjust the volume of the sound played by the earphone speaker; the sound adjusted by the volume control module is output to the earp...

Abstract

The invention discloses a headphone device with automatic volume control function, which comprises a headphone loudspeaker which is used for playing audios, a microphone which is near the headphone loudspeaker and is used to collect environmental sound near ears, an environmental sound analysis module which is connected with the microphone and is used to receive environmental sound signals which is collected by the microphone and process the signals, a volume control module which is connected with the environmental sound analysis module and the headphone loudspeaker and is used to receive analyzing results of the environmental sound analysis module and control volume which is outputted by the headphone loudspeaker and whether the sound is muted or not. The invention can accurately catch the environmental sound which is listened by the ears, thereby control the volume of sound which is input by the headphone, and exclude the influence of the environmental sound to headphone playing.

Description

technical field [0001] The invention relates to an earphone device, in particular to an earphone device with an automatic volume control function, which can automatically adjust the volume according to the external environment, and its application fields include but not limited to various portable devices and mobile communication devices with audio playback functions. Background technique [0002] The development of digital technology has brought great convenience to people. With the popularity of portable devices such as mp3 players, it is becoming a trend to walk with headphones and listen to music anytime, anywhere. However, the external environment is changeable. There are noisy people on the road, but the library is very quiet. Use the same volume to play music, and it may be difficult to hear the sound of the surrounding environment (hereinafter referred to as the ambient sound) in noisy places (the human ear will also hear the ambient sound while hearing the sound pl...
