As shown in FIG. 4 (a), the width of the groove provided in the sound introduction part (0401) is wider than the thickness of the mobile terminal (0402) to be inserted. It is supported stably in an inclined state. At this time, a gap (0403) is generated between the sound introduction unit and the portable terminal. Sound output from the mobile terminal propagates through the gap to the horn unit. Such a gap for sending sound introduced with the end of the mobile terminal inserted into the horn is called a sound propagation gap. The sound introduction part is configured to form a sound propagation gap. As shown in FIG. 4 (b), also in the sound introduction part (0404) including the back plate, a sound propagation gap (0406) is formed between the sound introduction part and the portable terminal 0405.

FIG. 5 is a conceptual diagram for explaining the horn part, and the outline of the right horn part is indicated by a dotted line. As shown in the drawing, the sound introduction part (0501) enters the inside of the housing (0502) of the horn part, and the sound propagates into the horn part. The end part of the sound introduction part that fits in the horn part is closed in the passing direction between the horn parts and is opened only upward by the groove. A tube (0503) is arranged so as to cover the open groove, and the sound propagated from the sound introduction portion proceeds while resonating in the tube, and is released from the central portion (0504) through the horn (0505). This tube is called a resonance tube.

FIG. 6 is a conceptual diagram showing a cross section of a sound booster for a portable terminal. (A) is the figure seen from the upper part, (b) is the figure seen from back, (c) is the figure seen from the front. As shown in FIG. 6A, both ends of the sound introduction part (0601a) are accommodated in the left and right horn parts (0602a, 0603a).

When the outer shape of the horn part is substantially rectangular, it is preferable that the cross section of the resonance tube is substantially rectangular. The resonance tube resonates the sound passing through the tube and contributes to volume enhancement. Since the sound volume enhancement effect is proportional to the pipe length of the resonance pipe, it is preferable to arrange the resonance pipe so that the pipe length becomes long. When the internal space of the horn part is substantially rectangular, it is possible to lengthen the pipe line the longest by arranging the resonance tube along the outermost contour of the internal space. In order to ensure a certain degree, it is effective to make the shape substantially rectangular.

In particular, as shown in FIG. 6B, it is preferable that the cross-sectional area of the resonance tube is gradually increased toward the open end of the sound. By comprising in this way, the horn whose opening becomes large can be comprised integrally by the resonance tube and the horn connected to the resonance tube, and particularly, the low frequency range can be made natural and rich.
