In the present embodiment, the bottom plate 1112 of the magnetic carrier 111 has four notches 1113, which are respectively disposed at four corners of the bottom plate 1112, and the four ends of the two lateral walls 1111 are respectively elongated to four positions where are above the four notches 1113. That is, each of the notch 1113 is located at a bottom portion of one end of the lateral wall 1111 and the corner of the bottom plate 1112. The two connecting brackets 132 of the two elastic members 13 are respectively and firmly disposed at the two bottom portions of the two ends of the two lateral walls 1111. In other words, the two elastic members 13 are connected with the two ends of the magnetic carrier 111 and the outer frame 12, wherein the two ends are not with the two lateral walls 1111. The two connecting brackets 132 of the two elastic members 13 are able to firmly position in the notches 1113 by means of adhering or welding. The magnetic element 11 remains in an inner space of the outer frame 12 of the speaker structure 1 in a suspension manner. The connecting brackets 132 of the elastic members 13 being connected with and firmly positioned in the magnetic element 11 will be better for the balance of the entire structure, so as to avoid the problem of large side-to-side swings while the magnetic element 11 is in the process of vibrating up and down.
The outer frame 12 has two fixing portions 121, which are respectively disposed at a bottom portion of the outer frame 12 with the two elastic members 13, the fixing portion 121 has a fixing slot 1211, and the fixing bracket 131 of the elastic member 13 is firmly disposed in the fixing slot 1211. Each of the elastic members 13 has two connecting arms 133, and one end of the connecting arm 133 is connected with one side of the fixing bracket 131, further, another end of the connecting arm 133 is connected with a connecting bracket 132. The fixing bracket 131 of the elastic member 13 is firmly disposed in the fixing slot 1211, and two sides of the fixing slot 1211 has two openings 1212. The two connecting arms 133 are outwardly extended from the two sides of the fixing bracket 13 to be through the two openings 1212 of the fixing slot 1211, and the connecting arms 133 are bent to outwardly extend for connecting with the two connecting brackets 132. More, the fixing bracket 131, the two connecting brackets 132 and the two connecting arms 133 are integrated as one body.
Accordingly, the connecting arm 133 is an s-type structure, and it is on demand. The shape of the connecting arm 133 should assure that the vibration frequency of the overall magnetic element 11 and the vibration frequency of the magnetic element 11 affecting the voice coil 15 to drive the vibration member 14 are close to each other, in order to form mutual cancellation, and avoid the vibration of the magnetic element 11 to affect the vibration and sound of the vibration component 14. A side, adjacent to the bottom plate 1112, of the connecting arm 133 has an avoidance gap 114, which is located on a moving path of the connecting arm 33 vibrating up-and-down or swinging side-to-side. In the process of the elastic member 13 absorbing the vibrations of the magnetic element 11, the up-and-down vibration or side-to-side swing of the connecting arm 133 of the elastic member 13 may not be interfered by the bottom plate 1112 of the magnetic carrier 111. In addition, the elastic member 13 is made of stainless or other elastic materials.
As to the present embodiment, during the power-on operation of the speaker structure 1, and the audio current passing through the voice coil 15, the voice coil 15 will be affected by the magnetic field force of the magnetic element 11, so that the voice coil 15 drives the vibrating element 14 to move and produce sound. In the meantime, the magnetic element 11 will also be subjected to the reaction force of the voice coil 15. The force received by the magnetic element 11 and the voice coil 15 is equal in magnitude, and the direction of the force is opposite, so that the magnetic element 11 is opposite to the voice coil 15 in vibration. While the magnetic element 11 is connected to the outer frame 12 through two elastic members 13, the vibration force of the magnetic element 11 is transmitted to the outer frame 12 through the two elastic members 13. As a result, the vibration force of the magnetic element 11 is absorbed by the elastic members 13 in order to highly decrease the affection to the outer frame 12, so as to the vibration member 14.
In the process of moving the speaker structure 1, the magnetic element 11 remains in the outer frame 12 in a suspension manner through the two elastic members 13, and obviously the two elastic members 13 play the roles of dampers for balancing the movements or vibrations of the magnetic element 11 in the speaker structure 1. Further, the two elastic members 13 are able to reduce the interferences and affections from environments as well.

Consequently, the connecting portion 172 will be power enough to support under the voice coil 15. Besides, the auxiliary elastic member 17 has two connecting arm portions 173 obviously. The connecting arm portion 173 is an s-type structure. The two connecting arm portions 173 are extended outwardly from the two sides of the fixing portion 171 to connect with the two sides of the connecting portion 172.

The shape of the auxiliary elastic member 17 can be adjusted according to the needs of users, and the shape of the auxiliary elastic member 17 needs to ensure the vibration frequency and stability of the entire voice coil 15. The auxiliary elastic member 17 may or may not be made of metal material, that is, the auxiliary elastic member 17 has better elastic recovery force and can stably operate the voice coil 15 in the magnetic element 11.

Accordingly, when the speaker structure 1 is working to let the magnetic element 11 of the speaker structure 1 vibrate and make sound relative to the voice coil 15, the bottom plate 1112 of the magnetic carrier 111 in the magnetic element 11 will move up and down due to the vertical vibrations, and the space for the down vibration displacement is limited by the limiting parts 212, so that the vibrations of the magnetic element 11 are limited within a certain range. The user can adjust the vertical height of the limiting part 212 as required, so as to adjust the vertical vibration range of the magnetic element 11. In addition, the user can also change the structural shape of the limiting element 212 according to requirements, and is not limited to a cross, a straight line, a circle, etc.
In summary, the present invention provides a speaker structure and a speaker device. The speaker structure of the first embodiment has a magnetic carrier plate and two magnetic modules. The two magnetic modules are arranged on the magnetic carrier, and the two voice coils correspond to the two magnetic modules, so that the vibration sound structure increases the variability of the sound. Then the supporting elastic member and the two auxiliary elastic members are respectively connected between the outer frame and the two voice coils, so as to stabilize the vibration of the two voice coils. The speaker structure of the second embodiment uses the first and second extensions of the outer frame to limit the range in which the magnetic carrier can vibrate upward when the magnetic carrier vibrates upward. The speaker device assembles the speaker structure of the first embodiment or the second embodiment through the case, and the case can limit the downward vibration range of the magnetic carrier of the speaker structure.
