Detailed Description
In order to facilitate understanding of those skilled in the art, the present invention will be further described with reference to the following examples and drawings, which are not intended to limit the present invention. The present invention will be described in detail with reference to the accompanying drawings.
Example 1
As shown in fig. 1 and fig. 2, the present embodiment provides a speaker for enhancing low frequency response, including a support 1, a drum paper 2, a voice coil 3, a magnetic mechanism 4 and a terminal 5, where the drum paper 2, the voice coil 3, the magnetic mechanism 4 and the terminal 5 are all installed on the support 1, the number of the voice coil 3, the magnetic mechanism 4 and the terminal 5 is two, the two voice coils 3 are respectively installed on two end surfaces of the drum paper 2, the two magnetic mechanisms 4 are respectively installed on the two voice coils 3, and the two terminals 5 are respectively electrically connected with the two magnetic mechanisms 4.
The utility model has the advantages as follows:
firstly, a magnetic mechanism 4 and a voice coil 3 are added, and the magnetic mechanism 4 and the voice coil 3 act simultaneously, so that the driving force of the loudspeaker is doubled;
secondly, because only one piece of drum paper 2 is arranged, when the two voice coils 3 act in the same direction, the driving force of the two voice coils 3 is applied to one piece of drum paper 2, which is equal to the effect of doubling, thereby achieving the effect of enhancing the low-frequency response of the loudspeaker and saving the size space;
thirdly, due to the addition of one voice coil 3 and one magnetic mechanism 4, the F0 (i.e. the resonant frequency) of the horn can be lowered without increasing the equivalent volume of the horn.
In addition, preferably, the two voice coils 3 in the present embodiment may have the same specification, and two voice coils 3 having different specifications may be used according to the improvement of the low frequency response that is actually required.
In this embodiment, the magnetic mechanism 4 includes a spacer 41, a magnet 42, a U-iron 43 and a washer 44, the U-iron 43 is mounted on the bracket 1, and the voice coil 3 and the spacer 41 are mounted in the U-iron 43; the washer 44 is arranged at one end of the gasket 41 close to the drum paper 2, and the magnet 42 is arranged between the gasket 41 and the washer 44; washer 44 and magnet 42 are both located within voice coil 3. The voice coil 3 is energized and vibrates in the magnetic field generated by the magnet 42, and the vibration is transmitted to the drum paper 2 to realize a sound effect.
