Abstract
The utility model relates to a miniature sounding device which comprises a vibration system, a magnetic circuit system, an auxiliary system and a conductive terminal, wherein, vibration diaphragms and a voice coil connected with the vibration diaphragm are arranged in the vibration system; a frame and a conductive terminal are arranged in the auxiliary system; a retaining component is arranged at one end away from the vibration diaphragm on the frame; a positioning part is arranged on the retaining component, wherein, a retaining part which is raised and connected with the positioning part is arranged on the retaining component; and the retaining part can be propped against the conductive terminal. When the conductive terminal is under too high pressure, the retaining part can perform the cushioning function to prevent the conductive terminal from deforming and failing and guarantee the stable performance of the miniature sounding device.
Description
[technical field]
The utility model relates to a kind of microphone device, relates in particular to a kind of mini-sound device.
[background technology]
In the process of portable equipment fast developments such as mobile phone, people are more and more stronger to the functional requirement of product, for this function of Music Appreciation of mobile phone, in order to make entertainment effect stronger, the pattern that the music belt vibration occurred, thus, the also corresponding quickening of the development of miniature electro-acoustic device.
Please join shown in Figure 4, the mini-sound device 2 ' of dependency structure, it comprises basin frame 21 ', be contained in magnetic bowl 22 ' in the basin frame 21 ', be placed in permanent magnet 23 ' in the magnetic bowl 22 ', be arranged on the voice coil loudspeaker voice coil 24 ' between permanent magnet 23 ' and the magnetic bowl 22 ', the vibrating diaphragm 25 ' that is connected with voice coil loudspeaker voice coil 24 ', covers the loam cake 26 ' that is connected to basin frame 21 ' and is positioned conducting terminal 27 ' on the basin frame 21 '.
Yet when excessive pressure put on the conducting terminal 27 ', this pressure can directly be absorbed by conducting terminal 27 ', thereby causes conducting terminal 27 ' deformation failure, causes the unstable properties of mini-sound device 2 '.
Therefore be necessary the mini-sound device of dependency structure is improved in fact.
[utility model content]
The purpose of this utility model is to provide a kind of mini-sound device of stable performance.
The purpose of this utility model is achieved in that a kind of mini-sound device, its involving vibrations system, magnetic circuit system, auxiliary system and conducting terminal, and vibrational system is provided with vibrating diaphragm and the voice coil loudspeaker voice coil that links to each other with vibrating diaphragm; Auxiliary system is provided with basin frame and conducting terminal, and the end away from vibrating diaphragm on the basin frame is provided with block piece, and this block piece is provided with the location division, and wherein, described block piece also is provided with the location division and links to each other and protruding stop part, and this stop part can abut on the conducting terminal.
Compared with prior art, when mini-sound device of the present utility model, stop part are subjected to excessive pressure at conducting terminal, play cushioning effect, avoid the conducting terminal deformation failure, guarantee the stable performance of mini-sound device.
