Embodiment
The loudspeaker applications of the utility model preferred embodiment in mobile phone, personal digital assistant (Personal Digital Assistant, PDA), in the portable electron device such as panel computer, be used for functions such as audio plays.
See also Fig. 1 and Fig. 2, described loud speaker 100 comprises installation portion 10, goes out sound face 20 and pad 30.
Described loud speaker 100 is rectangular body shape roughly.Described installation portion 10 comprises perisporium 12 and installed surface 14.Described installed surface 14 is that loud speaker 100 is towards the surface of the circuit board of electronic installation, for cooperating installation with the circuit board of electronic installation.This perisporium 12 is convexly equipped with formation around the periphery of installed surface 14, and relative two perisporiums 12 are spaced apart to be provided with a plurality of accepting grooves 142.In the present embodiment, each perisporium 12 is spaced apart to be provided with two accepting grooves 142, and then this installation portion 10 offers four accepting grooves 142 altogether.These four accepting grooves 142 roughly are positioned at the position of four drift angles of this installation portion 10 respectively.This accepting groove 142 is trapezoidal from perisporium 12 surfaces to lower recess.
Described go out sound face 20 dorsad this installed surface 14 arrange, when loud speaker 100 was mounted on the circuit board of electronic installation, this went out sound face 20 this circuit board dorsad.This goes out sound face 20 and is used for sounding.
See also Fig. 1 to Fig. 3, described pad 30 is arranged at the position of the diagonally opposing corner symmetry of installation portion 10.Pad 30 is used for the weld pad welding with the circuit board of electronic installation.When loud speaker 100 is soldered on the circuit board, the spacing of two pads 30 is relatively large, can make pad 30 have preferably with circuit board welding pad contacts, thereby avoid the situation of the welding loose contact that causes because of distance limit because of two pads 30 of loud speaker 100, also can avoid causing because of pad 30 assembly defects the situation of product assembly failure and heavy industry.In addition, when the pad 30 of this loud speaker 100 is installed, can be with these loud speaker 100 anti-terminating on the rotatable tool, two pads 30 of relative 180 degree rotation assemblings are to the position of two diagonally opposing corner symmetries of installation portion 10.In the present embodiment, this pad 30 is formed by the part of metallic elastic spare 32, and this metallic elastic spare 32 can partly be contained in the accepting groove 142 of any two diagonally opposing corner symmetries.This metallic elastic spare 32 1 end parts are contained in this accepting groove 142, and the other end extends out to the close corner position of installation portion 10 from this accepting groove 142, and protrude from the predetermined height of this installed surface 14 1.This metallic elastic spare 32 outstanding ends are pad 30, when this metallic elastic spare 32 is welded on the weld pad of circuit board, the outstanding end of metallic elastic spare 32 can with weld pad welding preferably, and metallic elastic spare 32 supports this installation portion 10 circuit board certain distance at interval, is conducive to the heat radiation of loud speaker 100 when work.
Be appreciated that described pad 30 also can be the weld pad that is arranged at perisporium 12 close corner position places.This weld pad can be arranged at two close drift angle places of these perisporium 12 any diagonally opposing corner symmetries.Because perisporium 12 protrudes from installed surface 14, when the weld pad of this loud speaker 100 was soldered to weld pad on the circuit board, perisporium 12 supported installed surfaces 14 circuit board certain distances at interval, is conducive to the heat radiation of loud speaker 100 when work.
Be appreciated that described pad 30 also can be the aciculiform pin that is arranged at the close corner position place of installation portion 10, this aciculiform pin is vertically stretched out by installation portion 10 and forms.Welding was fixed after this aciculiform pin can cooperate the welding plate hole that is arranged on the circuit board, so that this loud speaker 100 can be stable on the circuit board more.
Be appreciated that this loud speaker 100 also can be oval body shape.Described pad 30 is arranged at the position of loud speaker 100 diagonally opposing corner symmetries, also is relative two long limits that two pads 30 can be arranged at the installed surface 14 of this ellipse body loud speaker 100 respectively, and respectively near two relative minor face places.
The utility model loud speaker 100 two pads 30 are set in the position of diagonally opposing corner symmetry respectively, make the spacing of two pads 30 bigger, ease of assembly and can have preferably can make the weld pad welding of pad 30 and circuit board the time and contacts to the circuit board of electronic installation.Thereby make this loud speaker 100 have ease of assembly concurrently, reduce error and the preferable advantage of assembling effect are installed.
