Abstract

The utility model relates to a loudspeaker which comprises a frame and a vibrating diaphragm fixed on the frame. The loudspeaker further comprises a conducting strip arranged on the frame; the frame comprises a lug boss which extends out of the frame; the conducting strip comprises a first welding part which is exposed to the frame and used for welding a voice coil lead wire, a second welding part in electric connection with the outside, and a connecting part connected with the first welding part and the second welding part; and the second welding part is arranged on the lug boss and is exposed for facilitating electric connection with the outside. In the loudspeaker, the conducting strip is arranged in the frame by the mode of injection molding, therefore, the thickness of the loudspeaker is reduced, and the routing distance of the voice coil lead wire is effectively reduced.

Description

Loud speaker
[technical field]
The utility model relates to a kind of electroacoustic transducer, relates in particular to the loud speaker that in a kind of electroacoustic transducer the signal of telecommunication is converted into acoustical signal.
[background technology]
In recent years, world's information industry development is swift and violent, and mobile phone becomes the main flow of speech communication gradually, Bluetooth technology reaches its maturity, expansion that radio areas is used is used, and the development of the multi-functional industry of mobile phone, and novel telelecture and mobile phone are with emerge in multitudes such as Microspeakers.
But existing traditional loud speaker generally comprises the basin frame and is arranged on the pcb board of basin frame bottom, and loud speaker need carry out the circuit turn-on effect by pcb board, cause the whole height of loud speaker too high like this, and the cable run distance of voice coil leads is excessive.
Therefore, be necessary at above-mentioned loud speaker whole height too highly, the excessive deficiency of the cable run distance of voice coil leads improves.
[utility model content]
It is too high that the purpose of this utility model is to solve above-mentioned loud speaker whole height, the deficiency that the cable run distance of voice coil leads is excessive, and a kind of loud speaker is provided:
A kind of loud speaker, comprise basin frame and the vibrating diaphragm that is fixed on the described basin frame, described loud speaker also comprises the conducting strip that is arranged on the described basin frame, described basin frame comprises the extended boss of outwards deriving, described conducting strip comprises and exposes to first weld part, second weld part that is used for being connected with external electric and the connecting portion that is connected described first weld part and second weld part that is used to weld voice coil leads on the basin frame that described second weld part is arranged on the described boss and exposes so that be connected with external electric.
Preferably, described conducting strip and basin frame integrated injection molding.
Preferably, the basin frame of the described first weld part correspondence partly offers first location notch, offers first location hole that runs through the basin frame on described first location notch, and described first location hole is used for locating first weld part when injection moulding.
Preferably, the basin frame of the described second weld part correspondence partly offers second location notch, offers second location hole that runs through the basin frame on described second location notch, and described second location hole is used for locating second weld part when injection moulding.
Preferably, described first welding position in described vibrating diaphragm in the scope of basin frame orthographic projection.
Preferably, described conducting strip is divided into two and be provided with on the described basin frame side by side at interval.
The beneficial effects of the utility model are: by conducting strip is injection-moulded in the basin frame, thereby reduced the thickness of loud speaker, effectively reduced the cable run distance of voice coil leads.
[description of drawings]
Fig. 1 is the three-dimensional exploded view of the utility model loud speaker one embodiment;
Fig. 2 is the cutaway view of embodiment loud speaker among the utility model Fig. 1.
[embodiment]
The utility model is described in further detail below in conjunction with drawings and embodiments.
As depicted in figs. 1 and 2, the utility model provides a kind of loud speaker 1, comprise basin frame 10, be housed in magnetic bowl 11 in the basin frame 10, be housed in magnet steel 12 in the described magnetic bowl 11, be attached to described magnet steel 12 upper surfaces pole piece 13, be fixed on vibrating diaphragm 14, an end on the basin frame 10 and be fixed on voice coil loudspeaker voice coil 15 on the vibrating diaphragm 14, be fixed on the loam cake 16 on the basin frame 10 and be injection-moulded in conducting strip 17 in the basin frame 10, import the signal of telecommunication for voice coil loudspeaker voice coil 15 by conducting strip 17, in the magnetic gap that magnetic bowl 11 and magnet steel 12 form, do the motion of cutting magnetic line, thereby drive vibrating diaphragm 14 vibration soundings.
