Description
Technical field
The present invention relates to sound device technical field, more particularly to suitable for the miniature of notebook computer and tablet personal computer
Double-magnetic-circuit horn.
Background technology
With the progress of living standards of the people, the requirement in life to the audio-visual digital product such as notebook computer is also increasingly
Height, for loudspeaker as the indispensable accessory on the video and audio electronic product such as notebook computer, its volume is always then to limit with acoustic pressure problem
Two big bottlenecks of properties of product and portability.
The magnetic circuit of existing Microspeaker mainly adds one block of magnet and washer to form using a magnetic conductor bowl, after magnet magnetizes
It is assembled in magnetic bowl and magnetic loop is formed by the magnetic conduction of washer and magnetic conductor bowl.Existing magnetic circuit magnetic energy product is relatively small, particularly miniature
Horn magnetic circuit causes magnetic circuit magnetic energy product small because height can not be done big with size limitation magnet and do thickness, loudspeaker sensitivity
It is low, requirement of the people to the loudspeaker of the audio-visual digital product such as notebook computer can not be met.
The content of the invention
In order to overcome above-mentioned technological deficiency, it is an object of the invention to provide miniature double-magnetic-circuit horn, and it is not only simple in structure,
Required cost is low, and acoustical quality is good, can meet requirement of the people to high tone quality.
To achieve the above object, the present invention is achieved by the following technical programs：
Miniature double-magnetic-circuit horn, including support, the sound film being fixed at by glue on the support and are consolidated by glue
Surely the voice coil loudspeaker voice coil of the sound film bottom is located at, in addition to the washer, upper plate, interior being fixed at respectively by glue in the support
Magnet, outer magnetic ring and lower shoe, the outer magnetic ring are fixed between the upper plate and lower shoe by glue, the interior magnetic
Tie Tong crosses glue and is fixed on the lower shoe and in the outer magnetic ring, shape between the internal magnet and the outer magnetic ring
Into magnetic gap, one end of the voice coil loudspeaker voice coil is stretched into the magnetic gap.
Further, the side wall of the support is provided with several locating pieces, the washer, upper plate, internal magnet, outer magnetic ring
It is fixed on respectively by glue on locating piece with lower shoe.
Further, the side of the support is provided with terminal.
Further, the bottom of the lower shoe is provided with several heat emission holes.
Further, it is uniformly distributed on the sound film provided with groove.
In summary, it is an advantage of the invention that：Miniature double-magnetic-circuit horn, it includes support, and branch is fixed at by glue
Sound film on frame and the voice coil loudspeaker voice coil that sound film bottom is fixed at by glue, in addition to be fixed at respectively by glue in support
Washer, upper plate, internal magnet, outer magnetic ring and lower shoe, outer magnetic ring are fixed between upper plate and lower shoe by glue, interior
Magnet is fixed on lower shoe by glue and in outer magnetic ring, magnetic gap, voice coil loudspeaker voice coil is formed between internal magnet and outer magnetic ring
One end stretch into magnetic gap, the magnetizing direction of outer magnetic ring and internal magnet is on the contrary, form a magnetic loop, so as to than same volume
Strengthen 30% magnetic energy product with traditional magnetic circuit of area, and can be carried in the case where not changing existing loudspeaker other materials or part
This performance for toy trumpet of the sensitivity 2dB. of high loudspeaker has directly very big lifting.

Embodiment
Invention is further described below in conjunction with accompanying drawing and embodiment：
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4 and Fig. 5, miniature double-magnetic-circuit horn, including support 2, it is fixed at by glue
Sound film 1 on the support 2 and the voice coil loudspeaker voice coil 3 that the bottom of sound film 1 is fixed at by glue, in addition to consolidated respectively by glue
Surely washer 4, upper plate 5, internal magnet 6, outer magnetic ring 7 and the lower shoe 8 in the support 2, the outer magnetic ring 7 pass through glue
It is fixed between the upper plate 5 and lower shoe 8, the internal magnet 6 is fixed on the lower shoe 8 and set by glue
In in the outer magnetic ring 7, magnetic gap 12 is formed between the internal magnet 6 and the outer magnetic ring 7, one end of the voice coil loudspeaker voice coil 3 is stretched into
In the magnetic gap 12.
Wherein, the side wall of the support 2 is provided with several locating pieces 9, the washer 4, upper plate 5, internal magnet 6, outer magnetic
Ring 7 and lower shoe 8 are fixed on locating piece 9 by glue respectively.
Wherein, the side of the support 2 is provided with terminal 10.
Wherein, the bottom of the lower shoe 8 is provided with several heat emission holes 11.
Wherein, it is uniformly distributed on the sound film 1 provided with groove 13.
Wherein, the magnetizing direction of outer magnetic ring 7 and internal magnet 6 is on the contrary, form a magnetic loop, so as to than same volume and face
The magnetic energy product of long-pending traditional magnetic circuit enhancing 30%.
As shown in fig. 6, the present invention can improve more than 30% magnetic energy than magnetic magnetic circuit magnetic energy product in the tradition of formed objects
Product, and Br values are higher by 0.28Tesla, loudspeaker can be improved by being embodied in the case of not changing existing loudspeaker other materials or part
Sensitivity 3dB above lowest resonance frequencies are less than existing loudspeaker 100Hz, and power is higher by 0.5W, and the scope of frequency range is 600-
20KHz, this performance for toy trumpet have directly very big lifting.
In summary, of the invention its is not only simple in structure, and required cost is low, and acoustical quality is good, and people can be met to high pitch
The requirement of matter.
For those skilled in the art, it is various corresponding can be made according to above technical scheme and design for other
Change and deformation, and all these change and deformation should all belong within the protection domain of the claims in the present invention.
