The first graph 1210 of FIG. 12 shows that when the first part 351 and the second part 353 of the support member 350 are spaced apart from each other to form a second space S2, a speaker (e.g. Audio signals transmitted from the speaker 320 in FIG. 4B are connected to each other in a first space (e.g., the first space (S1) in FIG. 4b) and a second space (e.g., the second space (S2) in FIG. 4b). When resonating, it indicates the output sound pressure level of the audio signal. The second graph 1220 of FIG. 12 shows the output sound pressure level of the audio signal when the audio signal transmitted from the speaker 320 resonates only in the second space S2. The volume of the first space S1 may be about 0.04 cc, and the volume of the second space S2 may be about 0.49 cc.

Referring to FIG. 12, in a low frequency sound range, the first graph 1210 may have a greater SPL than the second graph 1220.
