Specific embodiment
It please refers to shown in Fig. 1 to Fig. 5, that show the specific structures of the embodiment of the utility model.
The front cover includes plastic body 10 and integral type produced by insert molding in the metal frame 20 on plastic body 10；The plastic cement
Main body 10 has hollow portion 11, and in hollow portion 11, which has for installing electroacoustic 20 produced by insert molding of metal frame
The installation cavity 21 of device main body is formed with several flexibly positioned arms 22, each flexibly positioned arm on the inner sidewall of the installation cavity 21
22 from the outside projection of inner sidewall of the installation cavity 21 of metal frame 20；The lower section of the plastic body 10 is provided with for installing electroacoustic
The first groove 12, the second groove 13 of device main body, the slot bottom of second groove 13 from the first groove 12 is recessed upwards, this first
Groove 12, the second groove 13, installation cavity 21 are mutually communicated, and the inner sidewall of first groove 12 is recessed with annular positioning groove 14；This
Place, the lateral wall of the electro-acoustic element main body are concavely provided with embedded groove (not shown), and the flexibly positioned arm 22 is flexibly positioned
