Description
Technical field
The utility model belongs to multi-functional magnetic circuit mechanism technology field, and in particular to a kind of Microspeaker and receiver
Multi-function magnetic line structure.
Background technique
It is higher to loudspeaker and earpiece requirement as smart phone develops, requirements at the higher level are proposed to structure, need ultrathin type,
Higher loudness is needed in acoustical behavior simultaneously, the shortcomings that the structure of multipath magnetic circuit currently on the market: 1. in process flow ratio
More complex, process is as follows: 1. center magnet steel gluing 2. center magnetic path forward direction magnetize 3. while magnetic circuit gluing 4. while magnetic circuit reversely fill
5. center magnetic path combines magnetic with side magnetic circuit, and the batch production cost of 2. products is relatively high, and usually entire magnetic circuit cost accounts for product
Cost ratio 40%, 3. in multipath magnetic circuit structure, from the angle of design it is difficult to ensure that magnetic circuit center magnetic path side magnetic circuit is due to magnetic pole side
To on the contrary, generation magnetic circuit magnetic field N and S are attracting, generally for hidden danger point is evaded, producer generallys use CCD inspection and pulling capacity
Test data.
Utility model content
In order to make up for the defects of the prior art, the utility model provides one kind to overcome complex process, and product is unstable, mentions
Rise the Microspeaker of the yield rate of magnetic circuit and the multi-function magnetic line structure of receiver.
The utility model is achieved by the following technical solution:
The multi-function magnetic line structure of a kind of Microspeaker and receiver, including U glasss, center magnet steel and center pole piece, institute
It states U glasss and forms basic magnetic circuit system with center magnet steel and center pole piece, U glasss of surroundings are T word structure, and T word structural bind has
Auxiliary magnetic circuit.
Further, the auxiliary magnetic circuit is made of long magnet steel, long pole piece, short magnet steel and short pole piece.
Further, center magnet steel is equipped in described U glasss, center magnet steel is equipped with center pole piece, two T claimed with one pair of them
Short pole piece and short magnet steel in word structure make it form three magnetic circuits.
Further, center magnet steel is equipped in described U glasss, center magnet steel is equipped with center pole piece, two T claimed with one pair of them
Long pole piece and long magnet steel in word structure and the short magnet steel in another pair of two T word structures claimed and short pole piece form five magnetic circuits.
The beneficial effects of the utility model are: the advantages of structure is simple, high degree of automation, reduces process procedure bring
Loss, promotes plant efficiency, product can the form of single magnetic circuit or multipath magnetic circuit arbitrarily switch according to the requirement in market.
Detailed description of the invention
The utility model will be further described below with reference to the accompanying drawings.

It further illustrates.
Attached drawing 1,2 is a kind of specific embodiment of the utility model.A kind of Microspeaker of the utility model and receiver
Multi-function magnetic line structure, including U cup 1, center magnet steel 2 and center pole piece 3, the U cup 1 and center magnet steel 2 and center pole piece 3
Basic magnetic circuit system is formed, 1 surrounding of U cup is T word structure, and T word structural bind has auxiliary magnetic circuit.
Further, the auxiliary magnetic circuit is made of long magnet steel 4, long pole piece 5, short magnet steel 6 and short pole piece 7.
Further, it is equipped with center magnet steel 2 in the U cup 1, center magnet steel 2 is equipped with center pole piece 3, claims with one pair of them
Two T word structures on short pole piece 7 and short magnet steel 6, make its form three magnetic circuits.
Further, it is equipped with center magnet steel 2 in the U cup 1, center magnet steel 2 is equipped with center pole piece 3, claims with one pair of them
Two T word structures on long pole piece 5 and long magnet steel 4 and the short magnet steel 6 in another pair of two T word structures claimed and 7 groups of short pole piece
At five magnetic circuits.
The multi-function magnetic line structure of a kind of Microspeaker of the utility model and receiver, U cup 1 are designed as T word machine structure,
T structural bind auxiliary magnetic circuit, magnetic circuit system are optimized for main magnetic circuit and add auxiliary magnetic circuit, can be according to market or client
It is required that selection, realizes single magnetic circuit, double magnetic circuit, three magnetic circuits, a variety of magnetic circuit combinations such as five magnetic circuits, the magnetic structure that can be customized, U
It is respectively cupro-nickel structure, copper bottoming 3-5 μ " nickel plating 6-10 μ " or plating Cr3+ coloured silk zinc 6-12 μ " that 1 plating of cup, which applies,.
