Abstract
The utility model relates to a kind of loud speaker, comprise voice coil loudspeaker voice coil, frame, cone basin, T iron, upper magnet, lower magnet and dust cover, described upper and lower magnet is separately fixed at the upper and lower of described T iron, upper and lower magnet and T iron are placed in described dust cover jointly, described dust cover top interference is connected with train wheel bridge, described frame is fixed on described train wheel bridge, the top of described cone basin is connected with described frame top by ring, be provided with described dust cap in the middle part of described cone basin, between described cone basin and described frame, be provided with the first reinforcement skin limit; The second reinforcement skin limit is provided with between described voice coil loudspeaker voice coil and described cone basin.The utility model bass vibrating diaphragm adopts first to strengthen skin limit and the second reinforcement skin limit, significantly enhance the rigidity of vibrating diaphragm, make medium and low frequency more effectively clear, under very large volume, still lower distortion be can keep, maximum undistorted output acoustic pressure and the dynamic range of audio amplifier added.
Description
Technical field
The utility model relates to audio amplifier manufacturing technology field, particularly relates to a kind of loud speaker.
Background technology
Loud speaker can convert the electrical signal to acoustical signal and be radiated the electroacoustic transducer gone in air.Traditional loud speaker is divided into electrodynamic type, electromagnetic type, electrostatic, piezoelectric type, ionic formula and pneumatic type etc. by operation principle.In the loud speaker of each type, using is dynamic speaker at most, the most widely, is also called coil-moving speaker.At present, when loud speaker sounding, voice coil loudspeaker voice coil promotes cone and takes exercises, and the application point of power is positioned at voice coil loudspeaker voice coil and the junction of boring basin.While motion, ring can give cone basin a tractive effort, and application point is between ring and cone basin.Because strong application point exists, cone the stressed of basin is not uniform.Once the rigidity of vibrating diaphragm is not enough, deformation can be produced under force.A lot of active audio amplifier sound dulling when large volume is sent out broken, and even completely losing definition just has much relations therewith.
Utility model content
The purpose of this utility model is the deficiency overcoming above-mentioned technology, and provides a kind of loud speaker, is convenient to fix, and improves film strength of shaking, prevents it to be out of shape.
The utility model for achieving the above object, by the following technical solutions:
A kind of loud speaker, it is characterized in that: comprise voice coil loudspeaker voice coil, frame, cone basin, T iron, upper magnet, lower magnet and dust cover, on described, lower magnet is separately fixed at the upper and lower of described T iron, on, lower magnet and T iron are placed in described dust cover jointly, described dust cover top interference is connected with train wheel bridge, described voice coil loudspeaker voice coil is arranged on described T iron, described frame is fixed on described train wheel bridge, centring disk is provided with between described voice coil loudspeaker voice coil and described frame, the top of described cone basin is connected with described frame top by ring, the bottom of described cone basin is connected with described voice coil loudspeaker voice coil, described dust cap is provided with in the middle part of described cone basin, the first reinforcement skin limit is provided with between described cone basin and described frame, described first strengthens the bottom that skin limit is placed in described ring, the second reinforcement skin limit is provided with between described voice coil loudspeaker voice coil and described cone basin.The utility model bass vibrating diaphragm adopts first to strengthen skin limit and the second reinforcement skin limit, significantly enhance the rigidity of vibrating diaphragm, make medium and low frequency more effectively clear, under very large volume, still lower distortion be can keep, maximum undistorted output acoustic pressure and the dynamic range of audio amplifier added.
Preferably, block rubber is filled with between described dust cap and described cone basin.Adopt the intensity that block rubber can increase dust cap and bore between basin.
The beneficial effects of the utility model are: the utility model bass vibrating diaphragm adopts first to strengthen skin limit and the second reinforcement skin limit, significantly enhance the rigidity of vibrating diaphragm, make medium and low frequency more effectively clear, under very large volume, still lower distortion be can keep, maximum undistorted output acoustic pressure and the dynamic range of audio amplifier added.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Embodiment of the present utility model is described in detail below in conjunction with accompanying drawing and preferred embodiment.As shown in Figure 1, a kind of loud speaker, comprise voice coil loudspeaker voice coil 1, frame 2, cone basin 3, T iron 4, upper magnet 5, lower magnet 6 and dust cover 7, on described, lower magnet is separately fixed at the upper and lower of described T iron, on, lower magnet and T iron are placed in described dust cover jointly, described dust cover top interference is connected with train wheel bridge 8, described voice coil loudspeaker voice coil is arranged on described T iron, described frame is fixed on described train wheel bridge, centring disk 9 is provided with between described voice coil loudspeaker voice coil and described frame, the top of described cone basin is connected with described frame top by ring 10, the bottom of described cone basin is connected with described voice coil loudspeaker voice coil, described dust cap is provided with in the middle part of described cone basin, the first reinforcement skin limit 11 is provided with between described cone basin and described frame, described first strengthens the bottom that skin limit is placed in described ring, the second reinforcement skin limit 12 is provided with between described voice coil loudspeaker voice coil and described cone basin.First strengthens skin limit and second strengthens skin limit employing Kraft material, ensures that audio amplifier is undistorted, improves the intensity of cone basin.The utility model bass vibrating diaphragm adopts first to strengthen skin limit and the second reinforcement skin limit, significantly enhance the rigidity of vibrating diaphragm, make medium and low frequency more effectively clear, under very large volume, still lower distortion be can keep, maximum undistorted output acoustic pressure and the dynamic range of audio amplifier added.
As further improvement of the utility model, between described dust cap and described cone basin, be filled with block rubber 13.Adopt the intensity that block rubber can increase dust cap and bore between basin.
The utility model bass vibrating diaphragm adopts first to strengthen skin limit and the second reinforcement skin limit, significantly enhance the rigidity of vibrating diaphragm, make medium and low frequency more effectively clear, under very large volume, still lower distortion be can keep, maximum undistorted output acoustic pressure and the dynamic range of audio amplifier added.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
