Problems solved by technology

For the loudspeaker device with this structure, its high-frequency frequency response curve will drop rapidly at more than ten K Hz, resulting in a high-frequency cut-off frequency, and cannot produce higher-frequency sound waves with better acoustic quality.
Due to the limitation of materials and crafts of traditional loudspeaker devices, it is difficult to increase its high-frequency cut-off frequency, and it is also difficult to significantly improve the mid-high frequency effect of the speaker device
[0004] Moreover, as portable electronic devices become thinner and thinner, the integrated design of its internal electronic components has become a design trend, and the traditional single-function speaker device no longer meets the requirements of new portable electronic devices.

Embodiment Construction

[0024] Below in conjunction with accompanying drawing, describe the content of the present invention in detail:

[0025] Such as figure 1 and figure 2 As shown, the specific embodiment of the speaker device of the present invention includes a vibration system, a magnetic circuit system and an auxiliary system. The auxiliary system includes a front cover 11 and a casing 12, and the front cover 11 and the casing 12 accommodate a fixed vibration system and a magnetic circuit system. The vibration system includes a diaphragm 4, a centering strut 3 and a voice coil 5 fixedly combined with the diaphragm 4, and the magnetic circuit system includes magnets and magnetic guides, such as figure 2 As shown, the magnetic circuit system is provided with a magnetic gap, and the voice coil 5 is suspended in the magnetic gap. The external electrical signal enters the voice coil 5, and the current change in the voice coil 5 set in the magnetic field causes the voice coil 5 to vibrate up an...

Abstract

The invention discloses a speaker device, which comprises a vibration system, a magnetic circuit system and an auxiliary system for accommodating and fixing the magnetic circuit system and the vibration system. The vibration system comprises a centring disk. The centring disk comprises a first fixing portion, a second fixing portion disposed in the first fixing portion, and a connecting arm connecting the first fixing portion and the second fixing portion. The center position of the second fixing portion is provided with a piezoelectric patch, the centring disk is provided with a first bonding pad corresponding to the piezoelectric patch, and the piezoelectric patch is connected electrically with the first bonding pad. The second fixing portion is provided with an antenna circuit. According to the invention, a signal produced by the piezoelectric patch can effectively improve the medium-high frequency effects of the speaker device and the acoustic performance of the speaker device; the antenna circuit combines an antenna device with the speaker device integrally; and the speaker device has the advantages of excellent acoustic performance, high integrated design and multiple functions.
