Background technology
Continuous variation along with the market demand, the development of various electronic products is more quick, wherein loud speaker is one of the important spare part of the sound output of electronic product, for the requirement of loud speaker also towards the design of directions such as microminiaturization, high tone quality, low cost, to meet the demand on the market.
Figure 1 shows that the exploded view of existing loud speaker: loud speaker 1 includes following 16, a ventilation net 17 and a circuit board 18 of a housing 10, a loam cake 11, a vibrating membrane 12, a voice coil loudspeaker voice coil 13, a pole piece 14, a magnet 15, a peviform.
Yet, existing loud speaker utilizes the gluing mode, with circuit board 18 gluings in housing 10 in conjunction with platform 103 places, needing to see through artificial assembling reaches, cause cost of manufacture higher so indirectly, and the use amount of glue also impacts for bond strength, in the time of need bearing bigger tension as circuit board 18 external wires, takes the circuit board 18 of gluing mode to exist the risk of separating from housing 10.
The utility model content
Because above-mentioned problem, the purpose of this utility model is to provide a kind of electro-acoustic conversion device with buckle-type board structure of circuit, it utilizes the edge, land of electroacoustic transducer that stop block is set, with so that circuit board places the land, make it to fix spacing and can not break away from the land, reach circuit board and firmly combine, solve the defective that prior art exists with electroacoustic transducer is.
For achieving the above object, the electro-acoustic conversion device with buckle-type board structure of circuit described in the utility model includes an electroacoustic transducer and a circuit board.Electroacoustic transducer is provided with a land in the bottom, the land periphery is respectively equipped with stop block, and circuit board is arranged at the land, and it is spacing fixed by those stop blocks.Utilize the edge, land of electroacoustic transducer that stop block is set, with so that circuit board places the land, make it to fix spacing and can not break away from the land, reach circuit board and firmly combine with electroacoustic transducer is.

Embodiment
Below in conjunction with the drawings and specific embodiments, the electro-acoustic conversion device with buckle-type board structure of circuit described in the utility model is described further.
Fig. 2 is the described appearance assumption diagram with electro-acoustic conversion device of buckle-type board structure of circuit of present embodiment; Include an electroacoustic transducer 100 and a circuit board 200, circuit board 200 is to utilize the buckle mode to be fixed in electroacoustic transducer 100 bottoms, has exempted existing loadspeaker structure utilization gummed mode, easily has in conjunction with unsteady situation.
Fig. 3 is the described exploded view with electro-acoustic conversion device of buckle-type board structure of circuit of present embodiment.Among the figure, electroacoustic transducer 100 includes a base 20, a magnetic drive apparatus 30, a voice coil loudspeaker voice coil 40, a vibrating membrane 50, a loam cake 60 and a ventilation net 70.Base 20 is made of plastics, it has a combined hole 21 in central authorities, and base 20 1 ends are provided with a ring protuberance 22, and ring protuberance 22 peripheries include a storage tank 23 and a smooth land 25, are provided with several air vent holes 24 in the storage tank 23 to be communicated in base 20 inside.Wherein, the periphery of land 25 is provided with several stop blocks 26, and the apical margin of each stop block 26 is provided with an overhead kick 27.What is particularly worth mentioning is that, these stop blocks 26 have respectively the long side of being located at land 25 and land 25 short side two partly, the stop block 26 that is positioned at long side is two in the present embodiment, and periphery away from ring protuberance 22, and the stop block 26 that is positioned at short side is one of each side in the present embodiment, and a stop block of each short side is connected in the periphery of this ring protuberance 22, and by this, but circuit board 200 buckles are limited in the land 25.
Magnetic drive apparatus 30 is made up of one first magnetic conductor 31, a magnet 32 and one second magnetic conductor 33.First magnetic conductive part, 31 edges are embedded in the combined hole 21 of base 20.Magnet 32 is installed in first magnetic conductive part 31, and second magnetic conductive part 33 is arranged at magnet 32 1 ends, makes the magnetic conductive part 31 of winning, second magnetic conductive part 33 and magnet 32 constitute the magnetic drive apparatus 30 of an internal magnetization.
Voice coil loudspeaker voice coil 40 is hung on the periphery between first magnetic conductive part 31, second magnetic conductive part 33 and the magnet 32, and is subjected to magnetic drive apparatus 30 effect and drives.
Vibrating membrane 50 bottoms are incorporated into voice coil loudspeaker voice coil 40 1 ends, and can make vibrating membrane 50 must be with voice coil loudspeaker voice coil 40 interlock.
Loam cake 60 keeps certain distance with vibrating membrane 50, and is fixed in base 20, and loam cake 60 is provided with several senders 61.
Ventilation net 70 is arranged at the storage tank 23 of base 20, to cover air vent hole 24, uses as regulating electroacoustic transducer 100 acoustics curves.
When voice coil loudspeaker voice coil 40 is subjected to current lead-through excitatory, magnetic field generation magnetic that voice coil loudspeaker voice coil 40 and magnetic drive apparatus 30 are produced or magnetic are scolded effect and are vibrated, and then drive vibrating membrane 50 generation vibrations, produce sound so that promote ambient air, and sound from sender 61.
