Speaker device

1. A speaker device, comprising:

a housing provided with an accommodating space; and

a sounding member accommodated in the accommodating space, wherein the sounding member comprises a magnetic circuit unit and a vibration unit provided with a diaphragm;

the housing comprises an upper housing and a lower housing, the lower housing is assembled with the upper housing to form the accommodating space;

the lower housing comprises: a metal bottom wall, a plurality of lower metal side walls spaced apart from each other and bending and extending from the metal bottom wall, and sealing connectors respectively provided between two adjacent lower metal side walls of the plurality of lower metal side walls;

an end of each of the plurality of lower metal side walls close to the upper housing bends and extends in a direction perpendicular to a vibrating direction of the diaphragm to form a bending edge, the bending edge and a bottom surface of each of the sealing connectors jointly form a sealing surface, and the sealing surface is connected to the upper housing to seal;

the metal bottom wall is a rectangular structure, the plurality of lower metal side walls bends and extends from four sides of the metal bottom wall toward the upper housing, the sealing connectors are respectively connected between two adjacent lower metal side walls of the plurality of lower metal side walls, the bending edge is flush with the bottom surface of each of the sealing connectors;

the metal bottom wall comprises a pair of long sides and a pair of short sides spaced apart from each other, the plurality of lower metal side walls is a first side wall, a second side wall, a third side wall and a fourth side wall, the first side wall and the second side wall are connected to the pair of short sides respectively, the third side wall and the fourth side wall are connected to the pair of long sides respectively;

the sealing connector comprise a pair of first connectors and a pair of second connectors, the pair of first connectors respectively connect the first side wall to the third side wall and connect the first side wall to the fourth side wall, the pair of second connectors respectively connect the second side wall to the third side wall and connect the second side wall to the fourth side wall;

the first connector comprise a corner portion, a first fixing portion and a second fixing portion, the first fixing portion and the second fixing portion are formed by extending from two opposite ends of the corner portion and in a direction away from each other, the first fixing portion is connected to the first side wall, the second fixing portion is connected to the third side wall or the fourth side wall.

2. The speaker device as described in claim 1 , wherein the second connector comprises a connecting body, a first bending arm and a second bending arm, the first bending arm and the second bending arm bend and extend from the connecting body toward the accommodating space; the first bending arm and the second bending arm are spaced apart from each other; the first bending arm is fixedly connected to the second side wall; the connecting body is fixedly connected to the third side wall or the fourth side wall; and the second bending arm extends into the accommodating space.

3. The speaker device as described in claim 1 , wherein the upper housing comprises a top wall, an upper side wall bending and extending from an edge of the top wall, a sounding channel connected to the upper side wall, a bracket extending from the top wall toward the accommodating space, and a frame fixedly connected to the bracket; the sounding channel communicates with the accommodating space; and the sealing surface abuts against and is fixed to the upper side wall and the frame.

4. The speaker device as described in claim 3 , wherein the diaphragm and the top wall are spaced apart from each other to form a front chamber; the front chamber communicates with the sounding channel; and the diaphragm is fixed between the frame and the bracket.

5. The speaker device as described in claim 3 , wherein the sounding member, the upper housing and the lower housing jointly enclose a rear chamber; the speaker device further comprises an air-permeable spacer located in the rear chamber; the air-permeable spacer is attached to the sounding member and fixedly connected to the bracket; and the air-permeable spacer, the bracket, the upper housing and the lower housing jointly enclose a powder filling space for being filled with a sound absorbing material.
