Description

Technical Field

[0001] The utility model belongs to the technical field of loudspeakers, in particular to a loudspeaker for headphones which can produce bass effects. Background Art

[0002] As the pressure of life becomes greater and greater, people tend to listen to music to relieve their emotions in quiet times. At the same time, as people continue to pursue a high-quality life, people have higher and higher requirements for the sound quality of headphones. Whether it is a speaker for headphones or a speaker for large speakers, the working principle is the same. The voice coil in a permanent magnetic field drives the diaphragm connected to it to vibrate and produce sound. However, since the speaker for headphones is very small and flat, it is impossible to make more adjustments to the internal structure, so the sound quality cannot be compared with the speakers of large speakers. However, the music styles on the market are diversified, and ordinary headphones and speakers cannot reflect rich sound details, especially for bass effects. At present, most of them are adjusted through simulated sound effects on software, but due to the limitations of the speaker structure, they cannot match, and after adjustments are made through software, all audio tones will be lowered, and the output effect is not ideal. Utility Model Content

[0003] The purpose of the present invention is to provide a speaker for headphones that can produce bass effect, so as to solve the problems raised in the above-mentioned background technology.

[0004] To achieve the above objectives, the present invention provides the following technical solutions:

[0010] Beneficial effects of the utility model:

[0011] During operation, a changing electrical signal is input to the voice coil, causing it to vibrate and push the vibration membrane. The movement of the vibration membrane causes the air to vibrate and make a sound. The vibration membrane not only vibrates to the outside, but also to the air in the chamber. An air column is formed in the sound guide tube, and the vibrating air can be output to the outside world through the sound guide tube. In comparison, the frequency at which the vibration membrane directly vibrates the external air is higher than the vibration frequency output from the sound guide tube. The sound guide tube can effectively reduce the vibration frequency and thus produce a better bass effect.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0020] Please refer to Figure 1-5 ;

[0021] The headphone speaker described in the present invention is intended to enhance the bass effect in ordinary audio and improve the user experience. It specifically includes a frame 1, a magnetic circuit assembly 2 is provided in the middle of the frame 1, and the magnetic circuit assembly 2 in this embodiment can be composed of a magnet 21, a voice coil 22 and a washer 23, wherein the voice coil 22 in the magnetic circuit assembly 2 is connected to the vibration membrane 3, and the vibration membrane 3 covers the surface of the frame 1. Specifically, the extension of the vibration membrane 3 is fixedly connected to the frame 1, so that a gap is provided between the vibration membrane 3 and the frame 1, and a cavity 4 is formed. The side of the frame 1 facing away from the vibration membrane 3 is provided with an outwardly extending sound guide tube 11, and the end of the sound guide tube 11 is provided with an opening 12 connected to the cavity 4; The chamber 4 in this embodiment is sealed except for the opening 12 of the sound guide tube 11; when working, a changing electrical signal is input to the voice coil 22, causing the voice coil 22 to vibrate and push the vibration membrane 3. The action of the vibration module causes the air to vibrate and make a sound; the vibration membrane 3 not only vibrates to the outside, but also vibrates the air in the chamber 4. An air column is formed in the sound guide tube 11, and the vibrating air can be output to the outside through the sound guide tube 11. In comparison, the frequency at which the vibration membrane 3 directly vibrates the external air is higher than the vibration frequency output from the sound guide tube 11. The sound guide tube 11 can effectively reduce the vibration frequency to better produce a bass effect.

[0022] Further explanation of the magnetic circuit assembly 2 is that a washer 23 is provided on the end face of the magnet 21, and the voice coil 22 is sleeved on the outer circumference of the magnet 21. When working, the voice coil 22 needs to push the vibration membrane 3 to move. When the voice coil 22 moves, it will pull the lead wire 24, which can easily cause wear of the lead wire 24. The lead wire 24 in this embodiment extends into the cavity 4, and the lead wire 24 is fixed to the inner side of the vibration membrane 3, and the side wall of the frame 1 is provided with a notch 13. After the lead wire 24 extends out of the notch 13, it is sealed with glue to maintain the sealing of the cavity 4; through such a structure, the lead wire 24, the voice coil 22 and the vibration membrane 3 can remain relatively stationary. When the voice coil 22 moves, the vibration membrane 3 and the lead wire 24 move synchronously, so that the lead wire 24 will not be pulled here. In addition, since the lead wire 24 is fixed, the lead wire 24 will not touch the frame 1 when the voice coil 22 moves, thereby avoiding abnormal noise affecting the sound quality.

[0023] Furthermore, a groove 31 for accommodating the lead wire 24 is provided on the inner side of the vibration membrane 3. The routing of the lead wire 24 is fixed by the groove 31 and is bonded and fixed to the lead wire 24 by glue. Specifically, glue can be applied in the groove 31 in advance, and then the lead wire 24 can be adhered along the track of the groove 31.

[0024] One of the embodiments of the present invention adopts a modular structure, which is more conducive to installation. In this embodiment, a through hole 14 is provided in the middle of the frame 1, and a receiving tray 15 is fixed in the through hole 14; before installation, the frame 1 and the receiving tray 15 are separated. First, the magnet 21 and the washer 23 are fixed and then fixed to the receiving tray 15. At the same time, the voice coil 22 is separated, and the lead wire 24 of the voice coil 22 is fixed to the vibration membrane 3. Then, the receiving tray 15 is fixed to the frame 1, and the voice coil 22 is placed on the outer periphery of the magnet 21. Finally, the vibration membrane 3 is fixed to the frame 1 to complete the installation.

[0025] In the present invention, a plurality of bass holes 16 are provided at the bottom of the frame 1, and a bass tuning paper 5 is provided on the outside of the frame 1. The bass tuning paper 5 blocks the plurality of bass holes 16. When working, the air in the chamber 4 vibrates, and at the same time, the air is transmitted from the bass holes 16 to the bass tuning paper to vibrate. Under the action of the bass tuning paper, the vibration frequency is reduced, thereby emitting a bass effect. The structure of the sound guide tube 11 makes the bass effect better.
