[0023] The utility model is further described below in conjunction with the accompanying drawings:
[0024] The directions described in the utility model specification, such as "up", "down", "left", "right", "front", "back", etc., are based on the directions of the drawings and are intended to facilitate the description of the relationship between the various components. They do not indicate the unique or absolute positional relationship between the various components. They are only one of the implementation methods of the utility model and are not a limitation on its implementation method.
[0025] like Figures 1 to 3 As shown, a horn assembly with an integrally formed structure includes a horn piece 1, a waveguide piece 2 is connected to the lower part of the horn piece 1, a sound guide channel 20 is provided in the waveguide piece 2 which passes through from top to bottom, a sound amplification channel 10 which is connected to the sound guide channel 20 and is larger at the top and smaller at the bottom is provided in the horn piece 1, the horn piece 1 and the waveguide piece 2 are an integral structure made by a secondary injection molding process, that is, the waveguide piece 2 is first injection-molded and then placed in a mold cavity, and then the horn piece 1 is injection-molded on the waveguide piece 2 by secondary injection molding, and the horn piece 1 is made into an integral structure by the above structure, so that a gap is avoided at the direct connection between the two, so that the inner walls of the sound guide channel 20 and the sound amplification channel 10 are coherent, flat and smooth, thereby reducing the loss of sound wave energy and improving the sound quality after amplification.
[0026] As a preference, Figure 1 , Figure 3 and Figure 5 As shown, a connecting plate 21 extending outward is provided on the side wall of the top of the waveguide member 2 , and the connecting plate 21 is partially or entirely inserted into the horn member 1 to improve the stability of the connection between the horn member 1 and the waveguide member 2 .
[0027] As a better implementation method, Figure 1 , Figure 3 and Figure 5 As shown, the connecting plate 21 is provided with a plurality of limiting protrusions 22 which penetrate through the horn member 1 and are partially exposed. Thus, when the waveguide member 2 is placed in the mold cavity, the ends of the limiting protrusions 22 can be used as supporting parts against the inner wall of the mold cavity, thereby serving as a limit and fixation for the waveguide member 2.
[0028] Similarly, if Figure 1 , Figure 3 and Figure 5 As shown, the connecting plate 21 is arranged on the front and rear side walls of the waveguide component 2, the left and right side walls of the top of the waveguide component 2 are provided with outwardly protruding limiting bosses 23, and the left and right side walls of the horn component 1 are provided with windows 13 for the limiting bosses 23 to extend out. When the waveguide component 2 is placed in the mold cavity, the limiting bosses 23 can be used as a supporting part against the inner wall of the mold cavity, thereby serving as a limit and fixation for the waveguide component 2.
[0029] In order to further improve the stability of the connection between the horn 1 and the waveguide 2, as Figure 2 and Figure 4 As shown, the waveguide component 2 is provided with a connection hole 24 for injection molding material to be poured into during secondary injection molding, and the horn component 1 is provided with a connection column 14 formed by injection molding material being poured into the connection hole 24 during secondary injection molding.
[0030] As a further optimization solution, Figure 5 As shown, the connecting hole 24 is located on the lower side of the connecting plate 21, and the connecting plate 21 is provided with a guide recess 25 for the injection molding material to pass through during the secondary injection molding at a position corresponding to the connecting hole 24. Since the horn piece 1 is a structure surrounded by thin walls, the horn piece 1 forms a connecting column 14 at the connecting hole 24, and therefore a larger amount of injection molding material is required at the position of the connecting column 14. The guide recess 25 increases the flow rate of the injection molding material from one side of the connecting plate 21 to the other side, so that more injection molding material flows to the position of the connecting hole 24, thereby avoiding the collapse and deformation of the horn piece 1 after injection molding due to uneven material or uneven temperature.
[0031] As a preference, Figure 1 As shown, the lower part of the horn component 1 wraps the upper part of the waveguide component 2, so that the connection position between the two has a larger wall thickness, reducing the vibration of the material caused by sound waves.
[0032] Preferably, a reinforcing rib plate 26 is provided between the front and rear side walls of the waveguide 2 and the connecting plate 21 to strengthen the structural strength of the connecting plate 21 and reduce the vibration of the connecting plate 21 caused by sound waves.
[0033] In order to improve the stability of the connection between the horn member 1 and the waveguide member 2, as Figure 3 and Figure 5 As shown, a plug-in board 27 extending upward and inserted into the horn member 1 is provided on the top of the waveguide member 2 .
[0034] In order to further improve the stability of the connection between the horn 1 and the waveguide 2, as Figure 3 and Figure 5 As shown, the plug plate 27 is provided with a plurality of connection recesses 28 so that during secondary injection molding, the horn member 1 can form reinforcing ribs at the connection recesses 28 .
[0035] The above is only an embodiment of the utility model, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the utility model, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
