[0002] Because each speaker focuses on a different frequency range, achieving both treble and bass performance requires two separate speakers, one dedicated to bass and the other to achieve a wider sound range. However, since conventional speakers often utilize a single-sided sound-emitting structure, two speakers are necessary to provide better treble and bass. However, for today's electronics, which are striving for smaller and thinner dimensions (such as laptops), more speakers mean more internal space is occupied, hindering the realization of a slim design.
