Abstract

The invention provides a loudspeaker capable of increasing the effective vibration area, which includes a shell, a vibration system and a magnetic circuit system. The diaphragm, the middle diaphragm and the lower diaphragm, the outer edges of the upper diaphragm, the middle diaphragm and the lower diaphragm are fixed on the casing, the middle diaphragm and the lower diaphragm are set around the magnetic circuit system, and the vibration system also includes the upper diaphragm and the upper diaphragm. The upper frame connected by the membrane and the lower frame set around the magnetic circuit system, the inner edge of the middle diaphragm is sandwiched between the upper frame and the lower frame, and the inner edge of the lower diaphragm is fixed on the lower frame. Space and sound guide channel, the storage space is separated by the upper diaphragm, the middle diaphragm, the lower diaphragm and the lower frame into the front cavity of the lower diaphragm for the sound of the lower diaphragm and the rear cavity shared by the upper diaphragm and the lower diaphragm. The acoustic channel communicates with the anterior cavity of the superior membrane and the anterior cavity of the inferior membrane, and the shell is provided with a sound channel communicating with the anterior cavity of the superior membrane.

Description

【Technical field】 [0001] The invention relates to the field of sound and electricity, in particular to a loudspeaker used in portable electronic products. 【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 includes a box body with an accommodating cavity and a sound-generating device arranged in the box body, and a sound outlet is formed through the box body. The sound emitting device in the related art has only one sound emitting surface, which is not conducive to the improvement of the sensitivity of the speaker. [0004] Therefore, it is necessary to p...
