[0002] A loudspeaker, also known as a horn, is a transducer that converts electrical signals into sound signals. The vibrating part of the loudspeaker's armature typically drives the diaphragm to vibrate via a conductor rod, thus producing sound. Traditionally, the conductor rod and armature were installed by creating a hole along the axis of the conductor rod in the armature, into which the conductor rod was inserted. Because both the hole and the conductor rod were small, this process required precise alignment of the hole and the conductor rod before insertion, making it inefficient in production.

[0033] In the following description, specific details such as particular system structures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of the present invention. However, those skilled in the art will understand that the present invention can be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.

[0034] See Figure 1-14The loudspeaker 100 in one embodiment of the present invention includes a magnetic circuit system 2 and a vibration system 1. The vibration system 1 includes an armature 11 that can vibrate under the action of the magnetic field of the magnetic circuit system 2, a transmission rod 12 disposed on the armature 11 for transmitting vibration, and a diaphragm 13 that vibrates under the drive of the transmission rod 12. The armature 11 includes a vibrating part 111 for generating vibration. One end of the vibrating part 111 is provided with a notch 1110 for installing the transmission rod 12. The opening direction of the notch 1110 is not parallel to the axial direction of the transmission rod 12. The transmission rod 12 is installed into the notch 1110 from the open end of the notch 1110 and fixed on the vibrating part 111. Figure 5 The arrow points in the direction of the opening of gap 1110.

[0035] When the loudspeaker 100 is working, the vibrating part 111 of the armature 11 vibrates in the magnetic field of the magnetic circuit system 2, and the transmission rod 12 vibrates together with the vibrating part 111. The transmission rod 12 transmits the vibration to the diaphragm 13, and the diaphragm 13 vibrates under the drive of the transmission rod 12, thereby producing sound.

[0036] Compared to the conventional mounting scheme of the conducting rod 12 and armature 11 of the loudspeaker 100 in the background art, the vibrating part 111 of the armature 11 of the loudspeaker 100 is connected to the conducting rod 12 through the notch 1110, which is easier to install. The conducting rod 12 and the armature 11 can be connected by welding (e.g., laser resistance welding) or glue bonding (e.g., manual glue application), which effectively improves production efficiency and ensures reliability. Moreover, it is compatible with multiple processes and can meet the needs of production lines with different processes, such as automated production lines and manual production lines.

[0037] See Figure 5-11 Furthermore, the opening direction of the notch 1110 is perpendicular to the axial direction of the transmission rod 12, and / or the notch 1110 penetrates along the thickness direction of the vibrating portion 111 of the armature 11. Thus, when the transmission rod 12 is installed radially not parallel to the opening direction of the notch 1110, for example, when the axial direction of the transmission rod 12 is aligned with the thickness direction of the vibrating portion 111 of the armature 11, the end of the transmission rod 12 may protrude from the vibrating portion 111 of the armature 11. Preferably, the vibrating portion 111 and / or the connecting portion 112 of the armature 11 are sheet-like. Figure 5 The arrow points in the direction of the opening of gap 1110.

[0038] See Figure 7 and 9Preferably, the notch 1110 includes a first side surface 11101 and a second side surface 11102, both located on the inner side. The first side surface 11101 and the second side surface 11102 are respectively located on both sides of one end of the opening 11100 near the notch 1110. The distance between the first side surface 11101 and the second side surface 11102 is larger as it gets closer to the opening 11100 of the notch 1110. That is, the distance between the first side surface 11101 and the second side surface 11102 gradually increases in the direction from the opening 11100 away from the notch 1110 to the direction closer to the opening 11100, thereby facilitating the installation of the transmission rod 12 from the opening 11100 into the notch 1110.

[0039] See Figure 7 and 9 Furthermore, the notch 1110 includes a first side surface 11101, a second side surface 11102, and a third side surface 11103, all located on the inner side. The first side surface 11101 and the second side surface 11102 are located on opposite sides of the end near the opening 11100 of the notch 1110, respectively. The third side surface 11103 is located at the end away from the opening 11100, between the first side surface 11101 and the second side surface 11102. The shape of the third side surface 11103 corresponds to the side surface of the transmission rod 12. The side surface of the transmission rod 12 abuts against the third side surface 11103, resulting in a good fit between the side surface of the transmission rod 12 and the third side surface 11103, thus improving the secure installation of the transmission rod 12 on the armature 11. Preferably, the side surface and the third side surface 11103 of the transmission rod 12 are arc surfaces, and the transmission rod 12 is cylindrical.

[0040] See Figure 12 Furthermore, the conductive rod 12 includes a rod-shaped main body 121 and a positioning portion 122 for positioning on the armature 11. The positioning portion 122 protrudes or recesses from the main body 121 and abuts against the armature 11 to achieve positioning of the conductive rod 12, thereby improving the installation efficiency of the conductive rod 12 and the armature 11 during the production of the high-efficiency loudspeaker 100. In some embodiments, see Figure 12 The positioning part 122 protrudes circumferentially around the main body part 121; in other embodiments, see Figure 13-14 The positioning part 122 protrudes partially in the circumferential direction of the main body part 121.

[0041] Preferably, the positioning part 122 is mounted on the main body 121 or is an integrally formed part of the main body 121. For example, the positioning part 122 is annular and fits onto the main body 121; or, the positioning part 122 is a protruding structure formed by bending and stamping on the main body 121.

[0042] And / or, the transmission rod 12 is connected to the armature 11 by glue (e.g., hand-applied glue) or welding (e.g., resistance welding) to fix the transmission rod 12 on the armature 11. This also demonstrates that the speaker 100 is compatible with a variety of manufacturing processes and can meet the needs of different production lines, such as automated production lines and manual production lines.

[0043] See Figure 2-4 Furthermore, the magnetic circuit system 2 includes a magnet 21, a yoke 22, and a coil 24. The coil 24 forms a hollow coil channel 25, and the magnet 21 and the yoke 22 form a hollow yoke channel 23. The hollow yoke channel 23 and the hollow coil channel 25 are positioned correspondingly and have the same penetrating direction. The vibrating part 111 of the armature 11 passes through the hollow coil channel 25 and the hollow yoke channel 23. The armature 11 also includes a connecting part 112, which connects the vibrating part 111 to the magnetic circuit system 2. The connecting part 112 and the vibrating part 111 are sheet-like, with one end connected and the other end extending in the same direction. Preferably, the other end of the connecting part 112 is fixedly connected to the outer side of the main body 121 of the yoke 22. Thus, when the speaker 100 is working, the coil 24 is energized, and the vibrating part 111 of the armature 11 vibrates in the magnetic field, which in turn drives the diaphragm 13 to vibrate and produce sound.

[0044] See Figure 5-11 Preferably, the vibration part 111 includes a base 1111 and an extension 1112. The extension 1112 is located at one end of the base 1111 and extends outward. The extension 1112 extends out of the hollow channel 23 of the magnetic yoke. A notch 1110 is located in the extension 1112. The extension 1112 is connected to the transmission rod 12.

[0045] The vibrating part 111 of the armature 11 of the loudspeaker 100 is connected to the conduction rod 12 through the notch 1110, which makes it easier to install. The conduction rod 12 and the armature 11 can be connected by welding (e.g., laser resistance welding) or glue bonding (e.g., manual glue application), which effectively improves production efficiency and ensures reliability. Moreover, it is compatible with multiple processes and can meet the needs of production lines with different processes, such as automated production lines and manual production lines.

For those skilled in the art, this utility model can have various modifications, combinations, and variations.
