Description

Technical Field

[0001] The utility model relates to the technical field of sound box equipment, in particular to a super bass compensator. Background Art

[0002] A speaker is generally composed of a speaker unit, a frequency division network and a cabinet. The speaker unit is the most important component. Usually, a speaker is an active radiation unit, including a diaphragm (also known as a paper cone), a magnet and a voice coil. The vibration of the diaphragm is used to push the air to produce sound. When the audio signal current flows through the voice coil of the speaker, the alternating magnetic field generated by the audio current in the voice coil interacts with the strong constant magnetic field generated by the permanent magnet to cause the voice coil to vibrate mechanically. The vibration of the voice coil drives the diaphragm closely connected to it to move, causing the surrounding large area of ​​air to vibrate accordingly, thereby converting mechanical energy into sound energy.

[0003] The speakers currently on the market can be divided into closed speakers, bass reflex speakers, empty paper cone speakers, etc. according to the cabinet structure. The bass reflex speakers add a sound outlet hole (i.e. bass reflex hole) on the closed speaker panel, and install a sound guide tube (i.e. bass reflex tube) at one end behind the bass reflex hole. The air inside the bass reflex hole can form an additional sound radiator. The empty paper cone speakers are developed based on the bass reflex speakers. They generally include a speaker and an empty paper cone. The empty paper cone is used to replace the bass reflex tube in the bass reflex speaker. The working principle is that after the speaker cone vibrates, the vibration of the air in the box drives the empty paper cone to vibrate, forming a resonance with the speaker. When the speaker is working, the empty paper cone will move back and forth according to the changes in the air in the box, and the air in the box will not leak in the early stage, so the sensitivity is very high. Whether it is a bass reflex or empty paper cone speaker, the low-frequency radiation waves generated by the speaker itself are reflected and output to improve the bass effect.

[0004] With the development of the market, the miniaturization and portability of speakers are becoming more and more important development directions of speakers. However, for mini speakers, due to size limitations, the speakers used cannot be too large, generally 2 inches or less, and the low-frequency effect is greatly limited. Therefore, the diaphragm currently on the market is installed to assist the sound. Since the added auxiliary generator (ie diaphragm) does not have a magnet, it is commonly known as a fake speaker. Therefore, this diaphragm is also called a passive basin, and its effect of enhancing the low-frequency band is very limited, and it cannot achieve a better bass effect. Utility Model Content

[0005] Based on the above description, the utility model provides a subwoofer compensator to solve the technical problem that the diaphragm added in the prior art adopts a passive driving mode, resulting in poor bass effect.

[0006] The technical solution of the utility model to solve the above technical problems is as follows:

[0007] A super bass compensator comprises a diaphragm and an active driving mechanism, wherein the middle part of the diaphragm generates bass when driven by the active driving mechanism.

[0008] On the basis of the above technical solution, the present invention can also be improved as follows.

[0009] Furthermore, the active driving mechanism includes a coil bracket and a connecting rod, the coil bracket is connected to a coil, the connecting rod is movably arranged inside the coil and can move axially when the current of the coil changes, and the end of the connecting rod away from the coil bracket is connected to the middle of the diaphragm.

[0010] Furthermore, the outer edge of the diaphragm is connected with a flexible suspension edge.

[0011] Further, the coil is electrically connected to the bass power of the speaker.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0013] The subwoofer compensator provided in the present application adopts an active driving mechanism to directly connect to the middle part of the diaphragm, and directly drives the diaphragm to vibrate through the active driving method, so that the vibration effect is better and the bass effect is significantly improved; in addition, the subwoofer compensator drives the diaphragm by cooperating with a connecting rod and a coil, and its movement is stable and the bass enhancement effect is obvious; by directly connecting the lead of the coil to the bass amplifier of the speaker, the coil directly converts the electrical energy of the bass amplifier into magnetic energy, and then acts on the connecting rod to make the connecting rod move, thereby driving the diaphragm to vibrate and produce bass. Its vibration frequency is consistent with the bass frequency of the bass amplifier, achieving a completely synchronous resonance effect and significantly enhancing the bass experience.
