[Prior Art] Pressing, speaker is widely used in various air conditioning system pipelines or noise elimination equipment, which is equipped with air conditioning or noise prevention design according to system planning, as shown in Figure 1 and Figure 2, respectively A perspective view and a transverse cross-sectional view of the conventional speaker assembly, the conventional speaker 1 includes an outer casing 10' in the outer phase body 10 in a parallel airflow direction, and a plurality of equal-width segments are respectively arranged from the middle to the left and right sides. The partition U is configured to form a linear passage 12 parallel to the airflow direction of the adjacent two partitions; and the speaker 1 of different sizes can be designed according to different requirements, so that the size of the partition 11 is M329716 inch. Or the number of configurations depends on the size and size of the speaker 1 and there are different sets of W airflow when the inlet end 13 of the speaker 1 enters the linear channel 12 (as shown by the solid arrow in Fig. 2), although the pressure drop and insertion loss can be achieved. Allowed · 'But the resulting noise sound wave (4) is moving toward the entrance end of the channel 12 (shown in dotted line _ in Figure 2), and is not effectively blocked, so that the noise cannot be effectively reduced in the speaker i The effect, · In addition, the design of the pre-market-ready m-box is not only necessary to meet the market demand of low cost, but also needs to balance the use of the function or meet the important conditions of pressure loss reduction and noise reduction. F red speaker, but can not easily meet the above multiple conditions; this creation is to improve the designer of the shortcomings of the speaker. [New content] The main purpose of this creation is to provide a speaker structure for the ventilation duct of the blower. The speaker is arranged outside the outlet end of the air supply chamber, and includes the position of the entrance/exit end of the internal relative speaker. Between the adjacent two partition plates, a channel having a small opening on one side and a small opening on the other side is respectively arranged, and a plurality of partition plates are formed into a w-shaped cross section which is symmetrically left and right; and the convex surface of the dispersing plate is respectively set with respect to the flow direction of the air flow. At an intermediate position between the larger openings of the adjacent two partitions, whereby when the blower is operated to allow air to be sent out through the outlet end of the blower chamber and then into the speaker, and then through the partition and then sent out from the outlet end, Some of the noise sound waves generated by the sound chamber will enter the speaker through the air supply room, and the noise of the noise can be effectively reduced by the blockage of the partition in the speaker, so as to achieve a good effect of reducing the noise of the blower operation. M329716 [Embodiment] In order to make the creation of the present invention more clear and detailed, the preferred embodiment is illustrated with the following illustrations. The structure and technical features of the present invention are described in detail as follows: Referring to Figures 3-8, respectively, The speaker structure of the air blower ventilation system of the present invention is arranged on the air supply system air supply pipeline. The embodiment is viewed from the perspective view, the side perspective view, the perspective view of the speaker 4, and the front view of the speaker 4. Rear view of the speaker 4 and a side perspective view of the speaker 4. The ventilation duct of the blower mainly includes an air inlet duct 2, a blower chamber 3, an axial flow blower 3〇 disposed in the air supply chamber 3 for supplying air, and an air duct 5 according to the flow direction of the airflow. The air inlet duct 2 is a box structure, and the inside is a passage structure for airflow; the air supply chamber 3 is a box structure, and the two ends of the box body are respectively an inlet end 31 and an outlet of the air flow. The end 32 has an axial flow blower 30 at the inner center for air supply, and the inlet end 31 and the outlet end 32 of the air supply chamber 3 are respectively connected to the outlet end of the air inlet pipe 2 and the inlet end of the air outlet pipe 5, respectively. The inlet end 45 (not shown) of the speaker 4 is fixedly coupled to each other; the outlet duct 5 is a box structure, and the inside is a passage structure for airflow. The structure of the speaker 4 is disposed outside the outlet end 32 of the air supply chamber 3. The assembly mode of the speaker 4 is not limited, and can be directly disposed in the wind official 5 or the entrance end 45 and the outlet of the speaker 4. The end is respectively fixedly coupled with the outlet end 32 of the air supply chamber 3 and the inlet end of the air outlet tube 5 (not shown). The speaker 4 includes: a box 40, a plurality of partitions 41 and a plurality of dispersions The plate 42, wherein the size of the box 40 is different according to different needs, and the shape is not limited to be square as shown in Figures 3, 4, 5 or other shapes designed according to special needs (not shown) And the inside of the box-M329716 40 is opposite to the inlet and outlet ends 45, 46 of the speaker 4, and the adjacent two partitions 41 are respectively arranged to open the channel 47 on one side and the other side is small. The plurality of partitions 41 form a left-right and a right-symmetrical symmetrical cross-section, and the first end surface 41 丨 and the second end surface 412 are provided to the partition 41 relative to the air flow. The outer surface of the first end surface 411 is not limited to a circular arc shape or Rounded shape (not shown) to reduce the pressure loss of the airflow and increase its flow Smoothness; the dispersing plate 42 is a long arc shape, and its outer shape (4) can be a (four) shaped cross section or other different angles of rounded contour cross section (not shown), and the arcuate convex surface is respectively disposed opposite to the airflow direction. The middle position of the larger opening 相邻 of the adjacent two partitions 41 makes the flow distribution of the airflow into the speaker 4 more uniform and increases the residence time of the noise energy, thereby effectively reducing noise. = As shown in Figures 5 and 6, the outer width and length of the speaker 4 are as small as 2472 ΜΜ (mm) and 1 〇 _, = points, depending on the _; The distance between the left side 43 or the 2 side 44 of the speaker 4 may be 6_, and the distance between the center of the arc surface of the == relative to the elimination speaker 4 =:: the second end surface 412 of the second partition 41 The edge of the stripe ", the radius of curvature of the dispersing plate 42 can be 125 liters. Material: = = perforated zinc steel plate or similar sheet coated with sound absorbing one:: fiber asbestos or similar materials, and the sound absorbing material can be improved. In order to be chemically inert to enhance the sound reduction, anti-shock effect and resistance of the speaker 4, the air is blown; when the blower 30 starts running, the air enters the wind into the air and passes through the air supply blade. 3:= M329716 In the speaker 4, some of the noise generated will be sent by
