Problems solved by technology

[0004] Yet the loudspeaker of related art mostly adopts common aluminum or wooden dome, and the two ends of its dome in the vibration direction are all smooth surfaces, when the loudspeaker of related art is placed in the loudspeaker box, make loudspeaker box to have obvious front. Cavity resonance, and the energy is too high near the high frequency resonance, which usually significantly amplifies distortion and noise

Embodiment 1

[0026] Please refer to Figure 1 to Figure 3 , the present invention provides a loudspeaker 100, the loudspeaker 100 includes a frame 11, a vibration system 13 and a magnetic circuit system 15 respectively fixed to the frame 11.

[0027] The vibration system 13 includes a diaphragm 131 fixed on the frame 11 and a voice coil 133 that drives the diaphragm 131 to vibrate and produce sound.

[0028] The diaphragm 131 includes a dome 1311, a vibrating part 1313 connected to the dome 1311, a ring part 1315 extending outward from the vibrating part 1313, and a fixing ring extending outward from the ring part 1315. Section 1317. The fixing portion 1317 is fixedly connected to the frame 11 , so that the diaphragm 131 is fixed to the frame 11 .

[0029] It should be noted that the vibrating part 1313 is connected to the dome 1311 in the vibrating direction, and in this embodiment, the vibrating part 1313 is ring-shaped, and the vibrating part 1313 and the dome 1311 Peripheral fixed c...

Embodiment 2

[0044] The structure of the speaker 200 provided in this embodiment is basically the same as that of the speaker 100 provided in Embodiment 1, except for the structure of the dome 2311 .

[0045] Please refer to Figure 5 with Image 6 , In this embodiment, the dome 2311 is a plate-shaped structure made of foamed metal material. Specifically, the foamed metal includes foamed aluminum, foamed nickel, etc., and in this embodiment, the foamed metal is foamed nickel.

[0046] Compared with the related technology, the loudspeaker of the present invention adopts a microporous structure at both ends of the dome along the vibration direction, because the microporous structure has relatively large acoustic damping, which can effectively reduce the energy of the resonant peak of the front cavity, Reduce distortion while reducing the amplification effect of high-frequency resonance on noise; at the same time, the microporous structure can improve the airflow direction in the speaker, s...

Abstract

The invention provides a loudspeaker which comprises a basin stand, a vibration system and a magnetic circuit system, the vibration system and the magnetic circuit system are respectively fixed on thebasin stand, the vibration system comprises a vibrating diaphragm fixed on the basin stand and a voice coil driving the vibrating diaphragm to vibrate and produce sound, the vibrating diaphragm comprises a globe roof, and two ends of the globe roof along the vibration direction are provided with microporous structures. Compared with the prior art, the loudspeaker provided by the invention has theadvantages that the two ends of the globe roof along the vibration direction are arranged into the microporous structures, so that when the loudspeaker is assembled into the loudspeaker box, the airflow noise in the front cavity of the loudspeaker box can be effectively reduced, and the purposes of improving the performance and the tone quality are achieved.

Description

【Technical field】 [0001] The invention relates to the field of electroacoustic conversion, in particular to a loudspeaker. 【Background technique】 [0002] With the advent of the mobile Internet era, the number of smart mobile devices continues to rise. Among the many mobile devices, the mobile phone is undoubtedly the most common and portable mobile terminal device. At present, the functions of mobile phones are extremely diverse, one of which is the function of high-quality music. Therefore, speakers for playing sound are widely used in current smart mobile devices. [0003] The loudspeaker of the related art includes a pot frame and a vibration system and a magnetic circuit system respectively fixed on the pot frame. The vibration system includes a diaphragm fixed on the pot frame and a voice coil that drives the diaphragm to vibrate and sound. The membrane includes a dome. [0004] Yet the loudspeaker of related art mostly adopts common aluminum or wooden dome, and the...
