Detailed Description
In the following, embodiments of the present utility model will be described in detail, for the purpose of making the objects, technical solutions and advantages of the embodiments of the present utility model more apparent, and in the following, technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the embodiments of the present utility model, and it is apparent that the described embodiments are some embodiments of the present utility model, but not all embodiments.
The terminology used herein is for the purpose of describing embodiments and is not intended to be limiting and/or limiting of the utility model.
For example, "in a certain direction", "parallel", "orthogonal", "center", "opposite", "front-rear-left-right", and the like indicate expressions of relative or absolute arrangement, and indicate not only such arrangement in a strict sense but also a state of relative displacement with tolerance or with an angle or distance that can obtain the same degree of function.
Example 1
As shown in fig. 1 to 4, the rolling vibration suppressing speaker is mainly composed of a magnet cover 10, a magnet group, a voice coil 30, a support body 40, a diaphragm 50, a dome film 60 and a support frame 70.
The magnetic group is composed of magnetic steel 21 and pole piece 22 which are stacked, the magnetic steel 21 is connected with the magnetic cover 10, namely, the magnetic steel 21 is positioned at the upper end surface of the magnetic cover 10, the pole piece 22 is positioned at the upper end surface of the magnetic steel 21, electromagnetic force is provided by the pole piece to drive the voice coil 30 to move, and vibration sounding is realized by matching the vibrating diaphragm 50 and the dome film 60.
The support frame 70 is adhesively fixed to the magnet cover 10, and has a space therein, thereby accommodating other components such as the magnet assembly and the voice coil 30 in combination with the magnet cover 10.
The voice coil 30 is a ring-shaped coil structure, is arranged around the magnet group and is not contacted with the magnet group, the support body 40 is in ring-shaped bonding and bonding on the upper part of the voice coil 30, namely, the lower surface of the support body 40 is bonded and arranged on the upper end surface of the voice coil 30, the support body 40 covers the voice coil 30, the wall thickness of the support body 40 is larger than that of the voice coil 30, the upper surface of the support body 40 is bonded and connected with the vibrating diaphragm 50, and the corresponding dome film 60 is bonded on the middle part of the upper surface of the vibrating diaphragm 50.
Here, the voice coil 30 and the support 40 are both annular structures.
Example 2
As shown in fig. 5 and 6, the difference from embodiment 1 is that the upper surface of the support body 40 is adhered and glued to the lower end surface of the voice coil 30, and the same support body 40 covers the voice coil 30, that is, the wall thickness of the support body 40 is larger than that of the voice coil 30, and at this time, the support body 40 is located in the gap between the magnet cover 10 and the magnet steel 21 and is not fixedly connected with the magnet steel 21 or the magnet cover 10.
