Description
Technical field
The present invention relates to a kind of New-type loudspeaker.
Background technology
At present, the principle of sound of loudspeaker is to convert electrical energy into mechanical oscillation, then disturbs air and becomes sound wave.Electric current
By electric wire inflow loudspeaker, the coil in loudspeaker produces magnetic field, and coil nearby sets magnet, is produced when positive pole is with respect to positive pole
It is raw to repel, received in vibrating diaphragm；When negative pole is with respect to positive pole, vibrating diaphragm is extended out, and sound, Ran Houtong are produced by the contraction and expansion of vibrating diaphragm
Audio amplifier is crossed to be amplified sound.The shortcomings that above-mentioned loudspeaker, is to need to carry out sound amplification by audio amplifier, adds manufacture
Cost and volume is expanded, use cannot be carried with, limit the use range of loudspeaker.
The content of the invention
The present invention is in order to solve problem of the prior art, there is provided it is a kind of simple in construction, manufacturing cost is relatively low and volume compared with
Small New-type loudspeaker.
To achieve the above object, the present invention adopts the following technical scheme that：A kind of New-type loudspeaker, including upper shell, first
Magnet, keeper, magnetostrictive member, voice coil, the second magnet and lower house, receiving portion is provided with the upper shell, it is described
First magnet is arranged in receiving portion and with upper shell against the keeper is arranged in receiving portion and pushes down first magnetic
Iron, the keeper are provided with through-hole section, and the magnetostrictive member is located in the through-hole section, and second magnet is arranged on
Below keeper, magnetostrictive member both ends respectively with first, second magnet against, the voice coil around being located at keeper appearance
Face, the lower house are provided with resettlement section, and the resettlement section is with the second magnet against upper shell connects with lower house, upper shell
There is resonant space between lower house, the lower house is provided with conducting piece.
It is below the attached technical scheme of the present invention.
Preferably, the diameter of the resettlement section of the lower house is more than the diameter of the receiving portion of upper shell.
Preferably, external screw thread is provided with the outside of the upper shell, internal thread, upper shell are provided with the inside of the lower house
It is connected through a screw thread between lower house.
Preferably, the upper shell and lower house are integrally formed by metal material.
Preferably, the voice coil is enamel-covered wire.
Preferably, the conducting piece is round sheet, and conducting piece is integrally formed by elastomeric material.
Preferably, first magnet and the second magnet are provided with lug boss, and the keeper both ends are provided with only
Stopper, the lug boss are stretched into the through-hole section and between stopper section.
The technique effect of the present invention：The New-type loudspeaker of the present invention simplifies the structure of loudspeaker, phase by resonance sounding
Volume is effectively reduced than conventional loudspeakers, consequently facilitating user carries, expands the use range of loudspeaker；It is in addition, above-mentioned
Loadspeaker structure is simple, and cost is relatively low, is easy to produce and promotes.
Brief description of the drawings
Fig. 1 is the exploded view of the New-type loudspeaker of the embodiment of the present invention.
Fig. 2 is the sectional view of the New-type loudspeaker of the embodiment of the present invention.
Embodiment
Below, the substantive distinguishing features and advantage of the present invention are further described with reference to example, but not office of the invention
It is limited to listed embodiment.
As depicted in figs. 1 and 2, the New-type loudspeaker 100 of the present embodiment include upper shell 1, the first magnet 2, keeper 3,
Magnetostrictive member 4, voice coil 5, the second magnet 6 and lower house 7.Receiving portion 11, first magnetic are provided with the upper shell 1
Iron 2 be arranged in receiving portion 11 and with upper shell 1 against.The keeper 3 is arranged in receiving portion 11 and pushes down described first
Magnet 2.The keeper 3 is provided with through-hole section 30, and the magnetostrictive member 4 is located in the through-hole section 30.Described second
Magnet 6 is arranged on the lower section of keeper 3, and the both ends of magnetostrictive member 4 are respectively with first, second magnet 2,6 against magnetostriction materials
Under magnetic fields, its length changes, can be subjected to displacement and do work or action of alternating magnetic field can occur to uphold repeatedly with
Shorten, so as to produce sound wave.The voice coil 5 is provided with resettlement section 71 around the outer surface of keeper 3, the lower house 7 is located at,
The magnet 6 of resettlement section 71 and second is against upper shell 1 and lower house 7 connect, and have resonance between upper shell 1 and lower house 7
Space 10, the lower house 7 are provided with conducting piece 8, are vibrated for transmitting.Above-mentioned technical proposal is produced by changing voice coil 5
Under raw magnetic field intensity, and the cooperation of resonant space 10, by sound conduction to conducting piece 8, conducting piece 8 need to be only placed on and led
On sound material (such as desktop or glass), you can produce sound wave concussion and transmit sound.
As depicted in figs. 1 and 2, further, the diameter of the resettlement section 71 of the lower house 7 is more than the receiving of upper shell 1
The diameter in portion 11.The outside of upper shell 1 is provided with external screw thread 12, and the inner side of lower house 7 is provided with internal thread 72, the He of upper shell 1
It is connected through a screw thread between lower house 7.Consequently facilitating the installation and removal of upper shell 1 and lower house 7.It is described in the present embodiment
Upper shell 1 and lower house 7 are integrally formed by metal material, and the voice coil 5 is enamel-covered wire.The conducting piece 8 is circle
Sheet, conducting piece 8 are integrally formed by elastomeric material.The magnet 6 of first magnet 2 and second is provided with lug boss 20, described fixed
The position both ends of part 3 are provided with stopper section 31, and the lug boss 20 is stretched into the through-hole section 30 and between stopper section 31.So that
Obtaining first, second magnet 2,6 can consolidate and must position.
The New-type loudspeaker of the present embodiment is simplified the structure of loudspeaker, had compared to conventional loudspeakers by resonance sounding
Effect reduces volume, consequently facilitating user carries, expands the use range of loudspeaker；In addition, above-mentioned loadspeaker structure is simple,
Cost is relatively low, is easy to produce and promotes.
Described above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications also should
