Referring to FIG. 2A to FIG. 2D together, the first speaker module 10 includes a fourth board member B4 in addition to the first, second, and third boards B1, B2, and B3. a fifth plate member B5, wherein the fourth and fifth plates B4 and B5 are respectively disposed on the upper and lower sides of the first, second, and third plates B1, B2, and B3, and are in the fourth and fifth portions. The plates B4 and B5 are respectively provided with openings B40 and B50 for accommodating different sounding monomers. It can be seen from the 2A-2D drawings that the first plate member B1 is H-shaped and has two grooves B11, and the second plate member B2 is U-shaped and has two protrusions B21. The protrusions B21 may be respectively passed through the grooves B11 (as shown in FIG. 2D), so that the first and second plates B1 and B2 perpendicular to each other may form a cross structure; then, two The first sounding unit S2 is respectively installed in the two openings B10 of the first plate member B1, and the second and third sounding units S2 and S3 are respectively installed in the opening B20 of the protruding portion B21. In order to make each The vocalization unit can transmit sound waves in different directions.

Referring to FIG. 3A and FIG. 3B, the first speaker module 10 of the embodiment further includes a fourth sounding unit S4 and a fifth sounding sheet on the fourth and fifth boards B4 and B5, respectively. The body S5, wherein the fourth sounding unit S4 faces the -Z axis direction (third direction), and the fifth sounding unit S5 faces the Z axis direction (the third direction is reversed). In this way, the first, second, third, fourth, and fifth sounding units S1 to S5 can be transmitted in different directions by their symmetrical arrangement and through the hollow structure formed by the plurality of plates. The sound wave is used to simulate the point source and achieve the non-directional sound effect, wherein the first sounding unit S1 and the second and third sounding units S2, S3 can be tweeter, midrange or full range ( The full-range speaker unit can be, for example, a SEAS FU10RB-8 horn unit, and its position is between the fourth and fifth utterance units S4 and S5.

On the other hand, as can be seen from the 3A and 3B, the second speaker module 20 has an upper casing 21, and the third speaker module 30 has a lower casing 31, wherein a sixth sounding unit S6 is disposed on one of the sixth plates B6 inside the upper casing 21, and faces the -Z axis direction (third direction), and a seventh sounding unit S7 is disposed on one of the seventh plates B7 inside the lower casing 21. And facing in the Z-axis direction (reverse direction of the third direction), wherein a bass reflex tube T is further disposed in the upper and lower housings 21, 31, and the position and direction correspond to the foregoing sixth and seventh utterances. Monomers S6, S7. It should be particularly noted that the assembled fourth and sixth sounding units S4 and S6 are accommodated in the upper casing 21, and the fifth and seventh sounding units S5 and S7 are placed in the lower casing. 31, wherein the first to seventh sounding units S1 to S7 are arranged along a central axis C direction (parallel to the Z axis) of the speaker device.

Referring again to Figure 3C, it can be seen from the figure that the lower casing 31 is It is composed of a plurality of plates, but in order to clearly show the internal structure thereof, the plate member on one side of the lower casing 31 is omitted in Fig. 3C. As shown in FIG. 3C, the seventh plate member B7 disposed inside the lower casing 31 is a multi-layer plate composed of two thin plates B71 and B72, and an opening B70 is formed in the center thereof to facilitate the seventh sounding unit. The sound wave emitted by the S7 is transmitted to the outside through the opening B70. Further, the sixth plate member B6 may have the same structure as the seventh plate member B7, and details are not described herein. Since the fourth, fifth, sixth, and seventh sounding units S4~S7 in the embodiment adopt a woofer or a subwoofer speaker unit (for example, a Seas L16RN-SL horn unit), The sounding frequency is lower than the sounding frequency of the first, second, and third sounding units S1 to S3. Therefore, the bass reflex tube T can be disposed inside the upper and lower casings 21 and 31 so that the low frequency sound is not distorted. And can effectively transmit sound waves to the outside world to produce a good sound field effect.

Moreover, as shown in FIGS. 4A and 4B, the speaker device of another embodiment of the present invention includes only the first speaker module 10, the third speaker module 30, and the base module 40, and the second speaker is omitted. The sound module 20 can thereby reduce the overall height of the speaker device to achieve space saving effect; or, the base module 40 can be omitted and the third speaker module 30 can be directly placed on the ground. It can be seen from FIG. 4A and FIG. 4B that a frame F and a dust-proof net N are disposed around the outer side of the first speaker module 10, and the dust-proof net N is attached to at least one side of the frame F (or The frame F is connected to the third speaker module 30 under the first speaker module 10, and is disposed around the four sides of the rectangular frame F.

Please continue to refer to FIG. 4B. The speaker device in this embodiment includes only the base module 40 and two interconnected speaker modules (first and third speaker modules 10, 30), and the two speakers are There are only six sounding units inside the sound module.
