Description

TECHNICAL FIELD

[0001] The utility model relates to audio signal processing technical field especially relates to a pocket module sound box. BACKGROUND

[0002] In daily life, mobile phones have become the most commonly used music playing tools for the public, and people are used to listening to their favorite music through the built-in speaker of the mobile phone. However, due to the need to accommodate many other functional components in the internal space of the mobile phone, the built-in speaker of the mobile phone has to adopt a very compact and simple structure design. This directly leads to a serious lack of sound restoration capability. When playing music, the sound quality is thin, lacks level and stereo sense, the low frequency depth is not enough, and the deep and heavy bass effect in the music cannot be presented. The high frequency extension is also very limited, and it is difficult to clearly show the high pitch details and clear tone of the musical instruments.

[0003] In order to improve the sound quality of music playing, consumers begin to seek external sound box devices. Pocket sound boxes have become the choice of many people due to their small and portable characteristics. Pocket sound boxes emphasize portability, with a small size that can easily fit into a pocket, meeting the needs of people to enjoy music anytime and anywhere in travel, sports and other scenarios.

[0004] However, the traditional pocket sound box has many shortcomings that cannot be ignored. In terms of sound effect, due to its small size and limited internal space, it can usually only set up one speaker. This single speaker is not up to the task when facing stereo audio signals, and it is impossible to distinguish left channel signals and right channel signals in the signals. Taking the playing of a popular song with rich stereo sound effects as an example, the traditional pocket sound box cannot accurately position the singer's voice and the different instrument sounds in the background music on the left and right channels, making the whole song sound flat and ordinary, and the original stereo surround effect disappears completely, greatly reducing the music effect and failing to allow users to feel the rich sense of space and level that the music creator intended to convey. From the perspective of function implementation, the traditional pocket sound box has relatively single function. Most of them only have basic audio playing function and lack deep processing capability for audio signals. For example, when facing different types of audio files, they cannot intelligently optimize them according to their audio characteristics. Whether it is high-quality lossless music or ordinary compressed audio, the playing effect is almost the same, and it is difficult to meet the needs of users for diversified audio experience.
