Problems solved by technology

[0005] The purpose of the present invention is to overcome the defects of the prior art and provide a loudspeaker to solve the problem that the overall height of the loudspeaker in the prior art is large and it is difficult to realize thinness and miniaturization. When encountering medium and high frequency vibration, it is easy to have the problem that the vibration of each position is not synchronized

Embodiment 1

[0034] see Figure 4 to Figure 10 , the loudspeaker according to the embodiment of the present invention will be described below.

[0035] The loudspeaker 100 of the present embodiment includes a support frame 10, a vibrating assembly 20, a radial magnet 30 and a PCB board 40, and further descriptions of the components of the loudspeaker 100 are given below:

[0036] The support frame 10 is provided for component installation;

[0037] The vibrating assembly 20 is used to vibrate to generate sound, and it is arranged on the support frame 10, wherein the vibrating assembly 20 includes a radial vibrating membrane 21 and a disc-shaped voice coil 22, and the center of the vibrating membrane 21 is provided with an outward convex Provided dome convex portion 211; and the transverse width of the voice coil 22 is greater than the longitudinal height of the voice coil 22, generally, the transverse width of the voice coil 22 is more than 10 times the longitudinal height of the voice co...

Embodiment 2

[0064] see Figure 11 , and combined with Figure 4 to Figure 10 , the implementation of Embodiment 2 is similar to that of Embodiment 1. For details, please refer to the implementation of Embodiment 1, which will not be described in detail here, and the difference between the two is:

[0065] In the second embodiment, the voice coil 22 is disposed on the inner wall surface of the spherical convex portion 211 . However, this embodiment can also better ensure that the vibrating assembly 20 composed of the voice coil 22 and the vibrating membrane 21 can vibrate better to generate sound.

Abstract

The invention discloses a loudspeaker which comprises a support rack, a vibration component arranged on the support rack, a radial magnet and a PCB, wherein the vibration component comprises a vibration membrane and a voice coil taking the shape of a round disc; a globe-roof convex part is arranged in the center of the vibration membrane; the voice coil is adhered to the bottom end surface of the vibration membrane; the central line of the voice coil is overlapped with that of the vibration membrane in a lowest position close to the inner wall of the globe-roof convex part; the radial magnet is positioned below the vibration component; the PCB is electrically connected with the vibration component. The loudspeaker disclosed by the invention mainly consists of the support rack, the vibration component, the radial magnet and the PCB, and due to the round disc shaped voice coil structure of the vibration component, the overall height of the loudspeaker can be less than 4.2 mm, so that the purpose of thinning and minimizing the loudspeaker is achieved; in addition, after a layer of the round disc shaped voice coil is overlapped on the vibration membrane, the problem that the vibration membrane is deformed can be greatly alleviated in the vibration process, so that the phenomenon that a frequency response curve is not flat as vibration is partitioned is avoided.

Description

technical field [0001] The invention relates to the technical field of electroacoustic transducer elements, in particular to a loudspeaker. Background technique [0002] In the field of modern acoustic and electric technology, the loudspeaker, also known as the horn, is an important transducer device, which is commonly found in various communication equipment, audio-visual equipment and other electronic devices. A uniform magnetic field is formed inside the speaker, and the voice coil made of conductive material is suspended in the uniform magnetic field of the speaker. Due to the action of the Loren magnetic force, when the signal carrying the sound characteristics in the voice coil changes, the voice coil will vibrate, which will drive the diaphragm to emit sound, and realize the conversion of electrical signals into sound. [0003] At present, the dynamic speaker is mainly composed of a support frame 20', a vibration assembly 10' disposed on the support frame 20', a magn...
