音箱音质和音效的好坏，跟扬声器音腔的尺寸有非常大的关系。后音腔的大小对声音的低频部分有巨大影响，声音的低频部分对音质影响强烈。后音腔越大，低音就越突出，主观上会觉得声音比较悦耳。因此，扩展后音腔对整体音效有很大的改善作用。而近年来，利用具有音腔的笔记本电脑、手机、随身听等手持数码设备来进行通话、收听音乐、进行声音处理的情况十分普遍。为了更加便于使用，该些手持数码设备被制造得越来越小，设备上的音腔的空间也受到了限制，也无法增设扬声器，故此音质和音效都很不理想，普遍存在低音不清晰、高音量破音等问题。The sound quality and sound effect of the speaker have a great relationship with the size of the speaker cavity. The size of the rear cavity has a huge impact on the low frequency part of the sound, which has a strong impact on the sound quality. The larger the rear cavity, the more prominent the bass, and subjectively feel that the sound is more pleasing to the ear. Therefore, the expanded sound cavity greatly improves the overall sound effect. In recent years, it is very common to use handheld digital devices such as notebook computers, mobile phones, and walkmans with sound chambers to make calls, listen to music, and perform sound processing. In order to be more convenient to use, these handheld digital devices are made smaller and smaller, the space of the sound cavity on the device is also limited, and it is impossible to add speakers, so the sound quality and sound effect are not ideal, and the common problems are unclear bass, Problems such as broken sound at high volume.
