For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of loud speaker, comprise shell and be contained in described shell interior vibrational system and magnetic circuit system, described magnetic circuit system comprises the basin frame, be provided with magnet and washer successively on the described basin frame, described basin frame and shell adhesive bond, the bottom of described basin frame is provided with tongue-and-groove, and the bottom of described shell is provided with the tenon that matches with described tongue-and-groove.
Wherein, described loud speaker is square structure, and four bights of described basin frame are equipped with described tongue-and-groove.
Wherein, described magnet and washer are strip structure, and the position of corresponding described magnet and washer is provided with first groove on the sidewall of described shell, and described basin frame, magnet and washer all part are positioned at described first groove.
Further, described loud speaker is rectangle structure.
Wherein, the centre position of described basin frame is provided with lug boss, and the bearing of trend of described lug boss is consistent with the bearing of trend of described loud speaker, and the bottom of described basin frame is positioned at the both sides of described lug boss; The magnet of described bar shaped and washer are arranged on the described bottom, are formed with magnetic gap between described magnet and washer and the described lug boss.
Wherein, also be provided with second groove that passes for the voice coil leads of described vibrational system on the described shell.
After having adopted technique scheme, the beneficial effects of the utility model are: because the bottom of the basin frame of the utility model loud speaker is provided with tongue-and-groove, the bottom of shell is provided with the tenon that matches with tongue-and-groove.This mortise structure that adopts between basin frame and the shell, compared with prior art increased the contact area between basin frame and the shell, the increase of contact area just makes that depositing the glue amount between basin frame and the shell increases, thereby strengthened the bonding strength of basin frame and shell, when being subjected to external impacts, can guarantee that magnetic circuit system can not come off from shell, and then prolong the useful life of product.And the mode of joggle is simple in structure, is easy to assembling, has strengthened the bond strength of basin frame and shell on the basis that does not increase assembly difficulty, has improved the performance of product on the whole.
Because four bights of basin frame are equipped with tongue-and-groove, namely are provided with four joggle positions between basin frame and the shell, have further increased the contact area between basin frame and the shell, thereby have further strengthened the bond strength of basin frame and shell.
As seen, the utility model loud speaker has solved the technical problem that the magnetic circuit system of loud speaker easily comes off from shell in the prior art.The utility model loud speaker has strengthened the bond strength of basin frame and shell on the basis that does not increase assembly difficulty, prolonged useful life.
