Embodiment 1

[0017] See attached figure 1 . A loudspeaker, comprising a diaphragm 1, a first surround 2, a voice coil bobbin 3, an elastic wave 4 and a frame 5; the diaphragm 1 is connected to the frame through the first surround 2 arranged on the outer edge of the diaphragm 1 5 On the ring face 6 provided on the inner edge of the top; the ring face 6 is provided with a sound outlet 7; Become the closed space that only sound outlet 7 is an outlet. It can be seen from the above structure that the present invention optimizes the design and optimization of the elastic wave and voice coil skeleton structure of the conventional dynamic speaker, and utilizes the vibration energy that was not used in the original design by redesigning the internal structure of the speaker unit. Increase the energy utilization efficiency of the loudspeaker to achieve the purpose of increasing the output sound pressure level. The outer edge of the diaphragm 1 is provided with a circle of first ring 2, the first ...

Abstract

The invention discloses a loudspeaker, which belongs to the technical field of sound boxes and comprises a vibrating diaphragm, a first folding ring, a voice coil framework, a damper and a basin stand, the vibrating diaphragm is connected to an annular surface part arranged on the inner edge of the top of the basin stand through a first folding ring arranged on the outer edge of the vibrating diaphragm; a sound outlet is formed in the annular surface part; and the vibrating diaphragm, the first folding ring, the voice coil framework, the damper and the basin stand form a closed space which only has a sound outlet as an outlet. According to the loudspeaker provided by the invention, the output sound pressure level can be increased in a projection product with a compact structure under the condition that the diaphragm size, the thickness size and the magnetic circuit size of the loudspeaker are not changed, the utilization rate of vibration energy is improved, up-conversion is efficiently carried out, and the performance of the loudspeaker is improved.

Description

technical field [0001] The invention belongs to the technical field of sound boxes, and in particular relates to a sound box. Background technique [0002] Speakers are a common sound-generating component in electronic products, and there are also sound-emitting speakers in projection products. Due to the small size and low power of projection products, there are often situations where the maximum output sound pressure level is not large enough. In order to increase the output sound pressure level, the conventional method is to increase the number of speaker units, increase the size of the magnetic circuit, or increase the rated power of the speaker. These measures not only increase the design cost but also increase the space occupation, which is difficult to implement in compact projection products. . It is a technical problem to be solved urgently to increase the output sound pressure level under the condition that the diaphragm size, thickness size and magnetic circuit ...
