[0002] In order to provide a better auditory experience, current consumer electronic products, especially notebooks and tablets, are usually equipped with low-frequency speaker modules and tweeter modules, and frequency division is performed. Since the F0 of the tweeter is relatively high and the volume enclosed by its sound cavity is small, the size of the tweeter module is usually small. Correspondingly, the space utilization rate of the cavity shell is low and the heat dissipation performance is relatively poor. Utility Model Content

[0004] The utility model solves the technical problem by adopting the following technical solution: a tweeter speaker comprises a diaphragm assembly, a voice coil, a basin frame, an ferrite, a magnetic steel and a magnetic bowl, the magnetic steel is arranged in the magnetic bowl and the basin frame, the ferrite is arranged on the magnetic steel, the magnetic steel and the ferrite are in a U-shaped shape with a hole in the middle, the basin frame, the ferrite, the magnetic steel and the magnetic bowl are closely matched to form a cavity that can be directly used as a rear cavity of a tweeter speaker module;
[0005] A diaphragm assembly is arranged at the top of the basin frame, a voice coil is arranged at the bottom of the diaphragm assembly, the voice coil is spaced outside the magnetic steel and the iron, there is a distance between the bottom of the diaphragm assembly and the iron, and the voice coil is suspended in the basin frame.
[0006] Furthermore, the magnetic steels are two spaced-apart magnetic strips, on which an elevon iron strip is disposed, and the elevon iron strip is in the shape of a U-shaped letter "H" with a hole in the middle.
[0007] Furthermore, the magnetic bowl has a circumference with a clearance gap, and the clearance gap is matched with a limiting protrusion on the inner side of the basin frame.
[0008] Furthermore, the ferrite is rectangular, and two long sides of the ferrite are arranged on the magnetic steel.
[0009] The length of the long side is equal to the length of the magnet, and the width of the short side opening is equal to the distance between the two magnets.
[0010] Furthermore, the length of the magnetic steel is equal to the inner length of the magnetic bowl.
[0011] Furthermore, it also includes a front cover, which is arranged above the diaphragm assembly, and the front cover and the basin frame fix the diaphragm assembly between the front cover and the basin frame.
[0012] The utility model has the beneficial effect that the tweeter speaker of the utility model utilizes the characteristic that the tweeter unit needs a small rear cavity, cuts off the parts with low magnetic performance utilization rate such as the center of the magnetic circuit, forms a cavity, makes the unit have a rear cavity, and cancels the sound cavity design. In this way, the cavity shell is cancelled, which not only saves a cavity installation process, reduces costs, but also improves the yield rate, and greatly improves the heat dissipation effect.
