Embodiment Construction

[0030] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0031] see Figure 1-7 As shown, the embodiment of the present invention provides a micro-speaker 100, including a housing 1 with a housing space 10, a vibration system 2, and a magnetic circuit housed in the housing space 10 for driving the vibration system 2 to vibrate. System 3. Wherein, the housing 1 includes a first side wall 11 and a second side wall 12 bent and extended from the edge of the first side wall 11 . The first side wall 11 and the second side wall 12 enclose the receiving space 10 . The housing 1 further includes a support plate 13 extending from the second side wall 12 into the receiving space 10 , and a first through hole 131 is formed on the support plate 13 .

[0032] Specifically, the vibration system 2 includes a voice coil 21, a first diaphragm 22, a diaphragm 23, and a second diaphragm 24 arranged at intervals along the shor...

Abstract

The invention provides a miniature loudspeaker, which comprises a shell, a vibration system and a magnetic circuit system, and is characterized in that a support plate is arranged in the shell; a first through hole is formed in the support plate; the vibration system comprises a voice coil, a first vibrating diaphragm, a diaphragm, a second vibrating diaphragm, a hollow first connecting piece clamped between the first vibrating diaphragm and the diaphragm, and a hollow second connecting piece clamped between the diaphragm and the second diaphragm, wherein the first vibrating diaphragm, the diaphragm and the second vibrating diaphragm are sequentially arranged at intervals along the short axis direction of the voice coil; the first vibrating diaphragm and the second vibrating diaphragm arefixedly held on the shell; the diaphragm is fixedly held on the support plate and covers the first through hole; the first vibrating diaphragm is connected with the voice coil; the first vibrating diaphragm, the shell, the support plate and the diaphragm form a first vibrating diaphragm front cavity; a second through hole is formed in the diaphragm; a third through hole is formed in the second vibrating diaphragm; and the first vibrating diaphragm front cavity is communicated with the outside through the hollow structure of the first connecting piece, the second through hole, the hollow structure of the second connecting piece and the third through hole in sequence. According to the miniature loudspeaker provided by the invention, higher bass performance can be realized.

Description

【Technical field】 [0001] The invention relates to the field of electroacoustic conversion, in particular to a micro speaker. 【Background technique】 [0002] In the existing side-firing micro-speakers, the vibration system generally only includes a diaphragm arranged on the side of the micro-speaker. This arrangement makes the effective radiation area of ​​the micro-speaker limited, resulting in limited bass performance under the same amplitude. That is to say, in the case of the same bass output, this setting method requires the micro-speaker to have a higher amplitude, which is not conducive to prolonging the life of the micro-speaker, but also requires a higher volume of the rear cavity of the mobile phone. [0003] Therefore, it is necessary to provide a micro speaker with a new structure to solve the above technical problems. 【Content of invention】 [0004] The object of the present invention is to provide a kind of microspeaker, the airflow enhancement system that is...
