Description
Technical field
The present invention relates to a kind of sound issue device, more particularly to a kind of loudspeaker.
Background technology
In the terminal, loudspeaker will externally make a sound, and be usually provided with sound outlet hole, these sound outlet holes be also electrostatic into
Enter the better channels of equipment.On the passage of these electrostatic invasion, the best method for defending electrostatic is exactly to dredge.Electrostatic is by going out
Sound hole, into the coil of loudspeaker, subsequently into the master chip of mobile equipment, so as to destroy master chip, prevents mobile equipment from just
Often work.
In addition, when having electromagnetic interference around loudspeaker, electromagnetic interference may be coupled to coil, causes loudspeaker to send ear-piercing
Noise.
The content of the invention
In view of the problems of the existing technology, a kind of loudspeaker are now provided.
Specific technical solution is as follows:
A kind of loudspeaker, including:
Horn bracket, the horn bracket surrounds the coil of the loudspeaker, to provide support for the loudspeaker;
Magnet steel, is electrically connected with the horn bracket;And the coil vibrates in the magnet steel;
The sound film being arranged between the horn bracket and the magnet steel, the sound film respectively with the horn bracket and institute
State magnet steel contact;
Wherein, one end ground connection of the magnet steel.
Preferably, further include:
Signal wire connecting portion, is electrically connected with the coil, to the signal for the coil output of transferring.
Preferably, further include:
Shell, is connected by a sound chamber sealing ring with the horn bracket.
Preferably, the first sound outlet hole is set on the shell;And the sound sends institute by first sound outlet hole
State outside loudspeaker.
Preferably, the number of first sound outlet hole is multiple.
Preferably, the horn bulb is equipped with the second sound outlet hole, and the position of second sound outlet hole goes out with described first
The position correspondence of sound hole.
Preferably, the material of the horn bracket is stainless steel material.
Preferably, the material of the sound film is insulating materials.
Preferably, the material conductive material of the magnet steel.
A kind of mobile terminal, including above-mentioned loudspeaker.
The beneficial effect of above-mentioned technical proposal is:
The cavity of an electric signal is formed after horn bracket and magnet steel are electrically connected, when loudspeaker are fitted into a mobile terminal
When, as long as magnet steel is connected with the earth signal of mobile terminal, this cavity reforms into a shield, passes through loudspeaker when there is electrostatic
During stent, because horn bracket is connected with the earth signal of mobile terminal, impedance is small, and electrostatic is by horn bracket, magnet steel by electrostatic
Release, so as to protect loudspeaker from the interference of electrostatic.
Brief description of the drawings
Fig. 1 is a kind of structure diagram of the embodiment of loudspeaker of the present invention.
Embodiment
It should be noted that in the case where there is no conflict, following technical proposals, can be mutually combined between technical characteristic.
The embodiment of the present invention is further described below in conjunction with the accompanying drawings:
A kind of loudspeaker are present embodiments provided, as shown in Figure 1, including:
Horn bracket, the horn bracket surrounds the coil of the loudspeaker, to provide support for the loudspeaker;
Magnet steel, is electrically connected with the horn bracket;And the coil vibrates in the magnet steel;
The sound film being arranged between the horn bracket and the magnet steel, the sound film respectively with the horn bracket and institute
State magnet steel contact;
Wherein, one end ground connection of the magnet steel.
In the present embodiment, if horn bracket is electrically connected without with magnet steel, there is electromagnetic interference around loudspeaker (receiver)
When, electromagnetic interference can be coupled to the coil of loudspeaker by horn bracket, cause loudspeaker to send ear-piercing noise.The present embodiment
In, horn bracket and magnet steel are linked together by conductive material, the cavity of an electric signal is formed, there is electricity around loudspeaker
During magnetic disturbance, because the shield that the stent of loudspeaker and magnet steel are formed, by electromagnetic interference signal shielding outside the coil of loudspeaker, make
Loudspeaker are from the interference of electromagnetic wave, and electrostatic can also be grounded by magnet steel and realize Electro-static Driven Comb, so as to prevent electrostatic from sending out loudspeaker
Go out sound to interfere.
In a preferred embodiment of the invention, further include:
Signal wire connecting portion, is electrically connected with the coil, to the signal for the coil output of transferring.
In a preferred embodiment of the invention, further include:
Shell, is connected by a sound chamber sealing ring with the horn bracket.
In a preferred embodiment of the invention, the first sound outlet hole is set on the shell;And the sound passes through institute
The first sound outlet hole is stated to send outside the loudspeaker.
In a preferred embodiment of the invention, the number of first sound outlet hole is multiple.
In a preferred embodiment of the invention, the horn bulb is equipped with the second sound outlet hole, second sound outlet hole
Position and first sound outlet hole position correspondence.
In above-described embodiment, loudspeaker will externally make a sound, so having had to sound outlet hole, these sound outlet holes are also electrostatic
Into the better channels of equipment, on the passage of these electrostatic invasion, the best method for defending electrostatic is exactly to dredge.The present embodiment
Antistatic loudspeaker (receiver) design of proposition is namely based on this theory and designs.
Loudspeaker sectional view in the terminal is as shown in Figure 1, sound film of trumpet and non-conductive, so horn bracket and magnet steel
Circuit connects, and electrostatic enters the coil of loudspeaker by sound outlet hole, if horn bracket does not have circuit to connect with magnet steel, passes through loudspeaker
Signal wiring pin enters the master chip of mobile terminal, so as to destroy master chip, makes mobile terminal cisco unity malfunction.
But in the present embodiment, horn bracket is connected with magnet steel circuit so that electrostatic by between loudspeaker and magnet steel be grounded,
Electro-static Driven Comb is realized, eliminates the interference that electrostatic works loudspeaker.
In a preferred embodiment of the invention, the material of the horn bracket is stainless steel material.
In a preferred embodiment of the invention, the material of the sound film is insulating materials.
In a preferred embodiment of the invention, the material conductive material of the magnet steel.
A kind of mobile terminal, including above-mentioned loudspeaker.
In the present embodiment, when loudspeaker load mobile terminal, as long as the earth signal phase in the magnet steel and mobile terminal of loudspeaker
Connection, this cavity reform into a shield.When have electrostatic by sound outlet hole reach horn bracket when because horn bracket and
The earth signal system of mobile terminal is connected, and impedance is small, and electrostatic is by horn bracket, magnet steel by the ground of Electro-static Driven Comb to mobile terminal
Signal system, so as to protect horn coil from the interference of electrostatic.
By explanation and attached drawing, the exemplary embodiments of the specific structure of embodiment are given, it is smart based on the present invention
God, can also make other conversions.Although foregoing invention proposes existing preferred embodiment, however, these contents are not intended as
Limitation.
