Problems solved by technology

[0004] However, in the sound-generating device of the related art, since the diaphragm is a single-fold ring structure, the vibration stiffness of the diaphragm of this structure is limited, and during the vibration process, when the vibration amplitude of the diaphragm is too large, the diaphragm is easily damaged, thereby greatly reducing the vibration reliability

Embodiment approach 1

[0042] Please also see Figure 1-3 As shown, the present invention provides a sound-generating device 100 , which includes a basin frame 1 , a vibrating system 2 and a magnetic circuit system 3 with a magnetic gap 30 . The vibration system 2 and the magnetic circuit system 3 are respectively fixedly supported on the basin frame 1, and the magnetic circuit system 3 is used to drive the vibration system 2 to vibrate and produce sound.

[0043] It should be noted that the specific structural form of the pot frame 1 is not limited, and it can be specifically set according to the actual use situation. For example, in this embodiment, the pot frame 1 includes a bottom plate 11, which is bent from the outer periphery of the bottom plate 11. The outer wall 12 is bent and extended and the inner wall 13 is bent and extended from the inside of the bottom plate 11. The outer wall 12 is arranged around the inner wall 13 and spaced from each other; of course, in practical applications, it i...

Embodiment approach 2

[0071] see Figure 4 As shown, the structure of the sound-generating device 100a in the second embodiment is basically the same as that in the first embodiment, and the same parts between the two will not be described one by one. Here, the second fixed part in the diaphragm of the two The structural forms and their positional connections are different. The following describes the specific structure:

[0072] In the second embodiment, the second fixing part 2132a of the diaphragm 21a is attached and fixed to the end of the second magnetic bowl bottom wall 341a away from the first magnetic bowl 31a, and by fixing the second fixing part 2132a to the upper end surface 3411a, effectively The bonding area between the second fixing part 2132a and the magnetic circuit system 3a is increased, so that the bonding between the two is firmer, and the reliability of the second fixing part 2132a is improved, thereby improving the vibration of the diaphragm 21a reliability.

Embodiment approach 3

[0075] see Figure 5-6 As shown, the structure of the sound-generating device 100b in the third embodiment is basically the same as that in the first embodiment, and the same parts between the two will not be described one by one. Here, the second fixed part in the diaphragm of the two The location and connection relationship of each is different, and the following description will be combined with the specific structure:

[0076] In Embodiment 3, the basin frame 1b includes a bottom plate 11b, an outer wall 12b bent and extended from the outer periphery of the bottom plate 11b, and an inner wall 13b bent and extended from the inner side of the bottom plate 11b. The outer walls 12b are arranged around the inner wall 13b and spaced apart from each other.

[0077] The inner wall 13b encloses the accommodation space 10b, and the magnetic circuit system 3b is fixedly accommodated in the accommodation space 10b. Specifically, the magnetic circuit system 3b is fixed to the inner wal...

Abstract

The invention provides a sound-generating device, which includes a basin frame, a vibration system supported on the basin frame, and a magnetic circuit system with a magnetic gap; the basin frame includes a bottom wall, an outer wall and an inner wall, and the outer wall surrounds the inner wall and is spaced from each other; the vibration system includes Diaphragm, voice coil and voice coil support; the diaphragm includes a vibration part, a first ring part and a second ring part bent and extended by the vibration part, a first fixed part bent and extended by the first ring part, and The second fixing part is bent and extended from the second ring part, the first ring part surrounds the second ring part and is spaced apart from each other, the first fixing part is fixed to the frame, and the second fixing part is fixed to the magnetic circuit system and / or Or the inner wall of the basin frame; the voice coil is inserted in the magnetic gap to drive the vibration part to vibrate and produce sound. Compared with related technologies, the sound emitting device of the present invention has high reliability.

Description

【Technical field】 [0001] The invention relates to the field of electroacoustic conversion, in particular to a sound generating device used in electronic sound box products. 【Background technique】 [0002] Sound generating devices, also known as loudspeakers or horns, are used in speakers to convert audio signals into sound playback. [0003] The sound-generating device in the related art includes a pot frame, a vibration system fixed to the pot frame, and a magnetic circuit system with a magnetic gap. The magnetic circuit system drives the vibration system to vibrate and produce sound. The vibration system includes a The diaphragm used to vibrate and sound, the voice coil support on the side of the spherical top of the diaphragm close to the magnetic circuit system, and the voice coil support wound around the voice coil support and inserted into the magnetic gap voice coil. [0004] However, in the sound-generating device of the related art, since the diaphragm is a single...
