Embodiment 1

[0021] Such as figure 1 and figure 2 As shown, this embodiment provides a loudspeaker with enhanced low-frequency response, including a bracket 1, a drum paper 2, a voice coil 3, a magnetic mechanism 4 and a terminal 5, the drum paper 2, the voice coil 3, the magnetic The mechanism 4 and the terminal 5 are all installed on the bracket 1, the number of the voice coil 3, the magnetic mechanism 4 and the terminal 5 are two, and the two voice coils 3 are respectively installed on the On both ends of the drum paper 2, two magnetic mechanisms 4 are mounted on the two voice coils 3 respectively, and two terminals 5 are electrically connected to the two magnetic mechanisms 4 respectively.

[0022] The beneficial effects of the present invention are as follows:

[0023] 1. The magnetic mechanism 4 and the voice coil 3 are added, and the magnetic mechanism 4 and the voice coil 3 will act at the same time, so it is equivalent to doubling the driving force of the speaker;

[0024] 2. ...

Embodiment 2

[0032] Such as image 3 As shown, what embodiment 1 provides is a drum paper 2 with a single-fold ring 21, while this embodiment provides a drum paper 2 with a double-fold ring 21, and the two ends of the drum paper 2 are respectively outward The protrusions form a ring 21 , and the two voice coils 3 are respectively located in the two rings 21 , which also achieves the effect of the first embodiment.

[0033] In order to avoid the impact on the characteristics of the speaker caused by the expansion of the air inside the two surrounding rings 21, in this embodiment, a through hole 22 is provided on the surface of one of the surrounding rings 21 to discharge air between the two surrounding rings 21. The amount of heat ensures that the inside of the ring 21 will not be overheated, thereby ensuring the sound producing effect of the present invention. The above is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although ...

Abstract

The invention relates to the technical field of audio devices and in particular relates to a loudspeaker for enhancing low-frequency response. The loudspeaker comprises a support, cone paper, voice coils, magnetic mechanisms and terminals. The cone paper, the voice coils, the magnetic mechanisms and the terminals are all arranged on the support; the number of the voice coils, the number of the magnetic mechanisms and the number of the terminals are all two; the two voice coils are arranged on the two end faces of the cone paper respectively; the two magnetic mechanisms are arranged on the twovoice coils respectively; the two terminals are all arranged on the support; and the two terminals are electrically connected with the two magnetic mechanisms respectively. According to the invention,the voice coils and the magnetic mechanisms are arranged at two ends of the cone paper; the two voice coils are directly bonded with one piece of cone paper; the voice coils move in the same direction, double driving force is achieved due to the fact that the two magnetic mechanisms are arranged, the advantage of greatly improving the sound pressure level is achieved, the use of the double voicecoils enables the vibration mass in the vibration system to be increased, and therefore the low-frequency response of the loudspeaker and the loudspeaker box is further expanded and enhanced.

Description

technical field [0001] The invention relates to the technical field of audio devices, in particular to a loudspeaker with enhanced low-frequency response. Background technique [0002] At present, in addition to increasing the quality of the speaker vibration system and sacrificing the sound pressure level of the speaker, the improvement of the low frequency of the speaker is achieved by adopting a large rear cavity volume. However, these methods have very little effect on the improvement of the loudspeaker, and cannot meet the requirements. Therefore, there is currently no speaker on the market that can effectively increase the low-frequency response and effect and increase the sound pressure level of the speaker. Contents of the invention [0003] The invention provides a loudspeaker with enhanced low-frequency response aiming at the problems in the prior art, which can enhance the low-frequency response without sacrificing the sound pressure level and without increasin...
