Description
Technical field
The utility model relates to speaker technology fields, and in particular to a kind of internal magnetic loudspeaker.
Background technique
Loudspeaker is a kind of energy transducer for electric signal being transformed into acoustical signal.When different electron energies reaches voice coil
When, voice coil generates a kind of energy and interacts with the magnetic field of magnet, and this interaction causes to rouse paper vibration, because electron energy is with time-varying
Change, the voice coil of loudspeaker can move forward or backward, therefore the drum paper of loudspeaker will be moved and then, these movements make air
Density degree changes and generates sound, and therefore, loudspeaker is widely used in the electronic equipment of sounding, as television set speaker,
Computer monitor loudspeaker etc..Currently, television set and other display technologies are ultra-thin knot in the environment of constantly bringing forth new ideas
Structure, therefore it is required that matched loudspeaker or monomer loudspeaker are also superthin structure, and this ultra-thin loudspeaker production side at present
Method is realized by way of directly compress loudspeaker thickness.Therefore when loudspeaker is integrally compressed, the movement of voice coil
Amplitude is smaller, so that the power termination ability of loudspeaker is greatly reduced, while it is too small to will lead to whole volume again.
Utility model content
The utility model embodiment discloses a kind of loudspeaker, can effectively solve conventional loudspeakers and is difficult to combine big sound
The defect of amount and the design of small structure, and there is water-proof function.
Internal magnetization kind loudspeaker provided by the utility model, including sound film, voice coil, bracket, washer, main magnet, secondary magnetic
Iron, U-shaped iron and pcb board, the bracket is equipped with and through-hole, and the U-shaped ferropexy is set in the through-hole, on the U-shaped iron
Equipped with groove, the main magnet is fixed at the groove of the U-shaped iron, and the washer is fixed on main magnet；The sound film
Fixed described voice coil one end is connected to the sound film on the bracket, and the other end of the voice coil is set to the main magnet
Between side wall and the inner sidewall of the U-shaped iron；The pcb board is fixed on described bracket one end and is electrically connected to the voice coil, institute
It is fixed on the bracket and positioned at the U-shaped iron two sides to state secondary magnet.Further, the through-hole of the bracket is equipped with recessed
Edge, the U-shaped iron through it is described it is recessed along it is fixed on the bracket.
Further, it is additionally provided with convex edge on the through-hole, the U-shaped iron is fixed on the through-hole through convex edge.
Further, the sound film is fixed on the bracket through marine glue.
Further, the bracket is equipped with boss, and the pair magnet is fixed on the bracket through the boss and phase
It is affixed on the facade of the U-shaped iron.
Further, limiting slot is additionally provided on the bracket, the pcb board is fixed at the bracket through the limiting slot
On.
Beneficial effect：The design that small structure is kept while increasing the performance of loudspeaker of the utility model, makes loudspeaker
Reach that stroke is small, the high effect of volume, effectively solve because product needs superthin structure and when loudspeaker being caused integrally to be compressed,
The mobile range of voice coil is smaller, so that the power termination ability of loudspeaker is greatly reduced, while it is small to will lead to overall loudness again
Problem, while sound film outer ring has waterproof.

Specific embodiment
Loudspeaker provided by the utility model by reasonably design can effectively solve conventional horn be difficult to take into account it is high-power
With the defect of small structure design.
A kind of embodiment provided in the utility model embodiment, please refers to Fig. 1 to 3, a kind of internal magnetic loudspeaker, including
Sound film 1, voice coil 2, bracket 3, washer 4, main magnet 5, secondary magnet 6, U-shaped iron 7 and pcb board 8, the bracket 3 be equipped with it is described
The corresponding through-hole 9 of U-shaped iron 7, the U-shaped iron 7 are set in 3 through-hole 9 of bracket, and the U-shaped iron 7 is equipped with groove, the master
Magnet 5 is fixed on the groove of the U-shaped iron 7, and the washer 4 is fixed on main magnet 5；The sound film 1 is fixed on the branch
On frame 3, described 2 one end of voice coil is connect with the sound film 1, and the other end is placed in the gap of the main magnet 5 and U-shaped iron 7；It is described
Pcb board 8 is fixed on described 3 one end of bracket and is electrically connected with the voice coil 2, and the pair magnet 6 is fixed on the bracket 3 simultaneously
Positioned at wherein, 3 through-hole 9 of the bracket is equipped with recessed along 10 with U-shaped 7 two sides of iron.
