For example, the mounting plate 21 may be an injection molded part in which the horn hole 213 and the vibrator hole 214 of the mounting plate 21 are formed while the mounting plate 21 is molded.

The main vibration horn 22 includes an active diaphragm 221, an active suspension 222, a voice coil 223, and a magneto-rheological system 224, wherein the outer side and the inner side of the active suspension 222 extend to be connected to the mounting plate 21 and the active diaphragm 221, respectively, wherein the high end of the voice coil 223 is connected to the active diaphragm 221, the low end of the voice coil 223 extends in a direction away from the back surface 212 of the mounting plate 21, and the low end of the voice coil 223 is coupled to the magneto-rheological system 224, so as to dispose the main vibration horn 22 on the mounting plate 21. When the main vibration loudspeaker 22 responds to the input of the audio signal, the magnetic return system 224 can drive the active diaphragm 221 to vibrate back and forth through the voice coil 223 to generate the sound effect, wherein the active suspension edge 222 is used for limiting the stroke of the active diaphragm 221 and ensuring that the active diaphragm 221 vibrates back and forth along the central axis of the main vibration loudspeaker 22.

Preferably, the active suspension 222 of the main vibration horn 22 is integrally coupled to the mounting plate 21 and the active diaphragm 221 at the time of molding, in such a manner that the coupling consistency of the active suspension 222 with the mounting plate 21 and the coupling consistency of the active suspension 222 with the active diaphragm 221 can be ensured in the circumferential direction of the main vibration horn 22. For example, in the process of manufacturing the in-line sound effect device 100, first, the mounting plate 21 and the active diaphragm 221 are placed in a molding die in such a manner that the active diaphragm 221 is held in the horn hole 213 of the mounting plate 21, and then, a molding material (e.g., a rubber material) is added to the molding die and the active bead 222 extending between the mounting plate 21 and the active diaphragm 221 is formed after the molding material is cured, such that the active bead 222 is integrally bonded to the mounting plate 21 and the active diaphragm 221 at the time of molding.

When the main vibration speaker 22 vibrates and generates sound in response to the input of the audio signal, the passive vibrator 23 can respond to the vibration of the main vibration speaker 22 to make the passive diaphragm 231 vibrate back and forth along the central axis of the passive vibrator 23 so as to generate an auxiliary sound effect, wherein the passive suspension edge 232 is used for limiting the stroke of the passive diaphragm 231 and ensuring that the passive diaphragm 231 vibrates back and forth along the central axis of the passive vibrator 23.

Preferably, the passive hanging edge 232 of the passive vibrator 23 is integrally coupled to the mounting plate 21 and the passive diaphragm 231 at the time of molding, in such a manner that the coupling conformity of the passive hanging edge 232 to the mounting plate 21 and the coupling conformity of the passive hanging edge 232 to the passive diaphragm 231 can be ensured in the circumferential direction of the passive vibrator 23. For example, in the process of manufacturing the in-line sound effect device 100, first, the mounting plate 21 and the weight 233 are placed in the molding die in such a manner that one weight 233 is held in the vibrator hole 214 of the mounting plate 21, second, molding material is added to the molding die and after the molding material is cured, the weight 233 and a portion of the molding material wrapping the weight 233 form the passive diaphragm 231, and another portion of the molding material forms the passive skirt 232 extending between the mounting plate 21 and the passive diaphragm 231, such that the passive skirt 232 is integrally bonded to the mounting plate 21 and the passive diaphragm 231 at the time of molding. Optionally, the outer side of the passive hanging edge 232 of the passive vibrator 23 is adhered to the mounting plate 21 by glue or similar adhesive.

It should be noted that naming the diaphragms of the main vibration horn 22 as the active diaphragm 221 and the suspension edge as the active suspension edge 222 and naming the diaphragms of the passive vibrator 23 as the passive diaphragm 231 and the suspension edge as the passive suspension edge 232 is to facilitate distinguishing the diaphragms and suspension edges of the active vibrator 22 and the passive vibrator 23 so as to avoid confusion. It should be understood that the specific names of the vibrating membranes and the overhanging edges of the main vibrating speaker 22 and the passive vibrator 23 do not limit the content and scope of the in-cell sound effect device 100 of the present invention, for example, the active vibrating membrane 221 of the main vibrating speaker 22 does not itself vibrate back and forth along the central axis of the main vibrating speaker 22, but vibrates back and forth along the central axis of the main vibrating speaker 22 when the magnetic return system 224 and the voice coil 223 of the main vibrating speaker 22 cooperate with each other to provide the driving force.
