Embodiment Construction
[0028] The preferred embodiments of the present invention will be further described below in conjunction with the drawings and implementation methods.
[0029] Such as figure 2 and image 3 As shown, the electroacoustic device 100 of the present invention includes a frame 101 , a vibration system 102 connected to the frame 101 , an upper cover 200 and a magnetic circuit system 103 placed in the frame 200 .
[0030] The basin frame 101 includes a side wall 111 and a receiving chamber 110 surrounded by the side wall 111 . The sidewall 111 has a top surface 114 , a bottom surface 115 opposite to the top surface 114 , and an inner surface 112 for enclosing the receiving cavity 110 . A positioning portion 113 extends from the bottom surface 115 to the top surface 114 of the side wall 111 of the basin frame 101 , and the positioning portion 113 communicates with the receiving cavity 110 . The positioning portion 113 makes the entire receiving cavity 110 a stepped hole.
