Description

Technical Field

[0001] The utility model relates to the field of loudspeakers, in particular to a loudspeaker diaphragm which is easy to install. Background Art

[0002] A speaker is a transducer device that converts electrical signals into sound signals. The performance of the speaker has a great influence on the sound quality. The speaker is the weakest device in the audio equipment, but it is the most important component for the sound effect. There are many types of speakers and their prices vary greatly. Audio electrical energy is transmitted through electromagnetic, piezoelectric or electrostatic effects, causing the paper cone or diaphragm to vibrate and resonate with the surrounding air to produce sound.

[0003] A loudspeaker is a transducer device that converts electrical signals into sound signals. Current loudspeakers are threadedly connected to threaded grooves by setting a fixing ring, which facilitates installation and removal of the fixing ring, thereby facilitating quick installation and removal of the diaphragm. By setting a spring, the distance between the cylindrical ring and the fixing ring can be adjusted, so that when the fixing ring is fixed to the outer cylinder, the fixing ring will exert an extrusion force on the spring, thereby exerting an extrusion force on the cylindrical ring, thereby increasing the extrusion force on the diaphragm and enhancing the fixing effect on the diaphragm.

[0004] However, when the speaker is working, the diaphragm will produce high-frequency vibrations, which will cause the boss extrusion ring connected to the cylindrical ring to move to one side and squeeze the spring, thereby generating vibrations and causing the stability of the diaphragm to decrease during operation.

[0005] Therefore, it is necessary to provide a speaker diaphragm that is easy to install to solve the above technical problems. Utility Model Content

DETAILED DESCRIPTION

[0026] The utility model is further described below in conjunction with the accompanying drawings and implementation modes. Example

[0027] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 ,in, Figure 1 A schematic structural diagram of a first embodiment of a loudspeaker diaphragm that is easy to install provided by the utility model; Figure 2 for Figure 1 The schematic diagram of the cross-section structure of the shell as a whole is shown; Figure 3 for Figure 2 The structural schematic diagram of the limit sleeve shown; Figure 4 for Figure 2 The enlarged schematic diagram of part A is shown. A speaker diaphragm that is easy to install includes:

[0028] A housing 1, one end of which is fixedly connected to a first limiting sleeve 2, the inner thread of the first limiting sleeve 2 is connected to a fixing sleeve 3, the bottom of the fixing sleeve 3 is fixedly connected to a positioning ring 31, and a diaphragm 7 is provided on the surface of the positioning ring 31;

[0029] Two fixing grooves 4, both of which are arranged inside the fixing sleeve 3, both of which are slidably connected with fixing pins 41, one end of each of the fixing pins 41 and located inside the two fixing grooves 4 are provided with fixing springs 42, and one side of each of the fixing pins 41 is fixedly connected with a fixing handle 43;

[0030] The mounting groove 5 is arranged inside the first limiting sleeve 2 , and the second limiting sleeve 51 is fixedly connected inside the first limiting sleeve 2 .

[0031] The two fixing grooves 4 are both provided inside the fixing sleeve 3 , and one side of the two fixing pins 41 is fixedly connected with a fixing handle 43 for facilitating the movement of the two fixing pins 41 .

[0032] The first limiting sleeve 2 is provided with an internal thread inside, and the surface of the fixing sleeve 3 is provided with an external thread matching the internal thread, so that the fixing sleeve 3 is aligned with the first limiting sleeve 2 and rotated to one side, so that after the fixing sleeve 3 moves to one side inside the first limiting sleeve 2 to a suitable position, the positioning ring 31 squeezes and limits the diaphragm 7.

[0033] The mounting groove 5 is provided inside the first limiting sleeve 2 . The second limiting sleeve 51 is an inner gear sleeve. One end of the fixing pin 41 is matched with the second limiting sleeve 51 , and is used to limit the fixing sleeve 3 after the second limiting sleeve 51 is engaged with the fixing pin 41 .

[0034] The working principle of the loudspeaker diaphragm provided by the utility model which is easy to install is as follows:

[0035] During use, when the diaphragm 7 is disassembled, the two fixing handles 43 are moved to one side, thereby driving the two fixing pins 41 to move to one side inside the two fixing grooves 4 respectively, while squeezing the two fixing springs 42. When the fixing pins 41 are separated from the second limiting sleeve 51, the two fixing handles 43 are rotated to one side to drive the fixing sleeve 3 to rotate to one side inside the first limiting sleeve 2. After moving to one side and separating, the diaphragm 7 can be taken out.

[0036] When installing the diaphragm 7, after placing the diaphragm 7 inside the shell 1, the fixing sleeve 3 is aligned with the first limiting sleeve 2 and then rotated to one side. Thus, after moving to one side to a suitable position inside the first limiting sleeve 2, the positioning ring 31 squeezes and limits the diaphragm 7. After loosening the two fixing handles 43, the two fixing springs 42 push the two fixing pins 41 to move to one side inside the two fixing grooves 4 respectively and engage with the second limiting sleeve 51 to limit the fixing sleeve 3.

[0037] Compared with the related art, the speaker diaphragm provided by the utility model which is easy to install has the following beneficial effects:

[0038] The utility model provides a loudspeaker diaphragm that is easy to install. After the diaphragm 7 is placed inside the shell 1, the fixing sleeve 3 is installed and the diaphragm 7 is squeezed by the positioning ring 31, so that the diaphragm 7 can be quickly installed and disassembled. At the same time, the fixing spring 42 pushes the fixing pin 41 to engage with the second limiting sleeve 51 to limit the fixing sleeve 3, so as to prevent the fixing sleeve 3 from loosening when the diaphragm 7 vibrates at a high frequency, thereby increasing the fixing effect of the fixing sleeve 3 and increasing the stability of the diaphragm 7 when it is working. Example

[0039] Please refer to Figure 5 and Figure 6 Based on the speaker diaphragm that is easy to install provided in the first embodiment of the present application, the second embodiment of the present application provides another speaker diaphragm that is easy to install. The second embodiment is only a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0040] Specifically, the second embodiment of the present application provides a speaker diaphragm that is easy to install. The difference is that, in the speaker diaphragm that is easy to install, a dustproof net 8 is provided inside the fixing sleeve 3, and two limiting grooves 9 are opened inside the fixing sleeve 3.

[0041] The interiors of the two limiting grooves 9 are both slidably connected to limiting blocks 10 , and one side of the two limiting blocks 10 is fixedly connected to the surface of the dustproof net 8 .

[0042] Two limiting holes 11 are formed inside the fixing sleeve 3 , and limiting pins 12 are threadedly connected inside the two limiting holes 11 .

[0043] The limiting pin 12 is a bolt, and two limiting holes 11 adapted to the limiting pin 12 are provided inside the fixing sleeve 3 for moving to one side inside the limiting holes when the limiting pin 12 rotates to one side.

[0044] The fixing sleeve 3 has two movable grooves 13 formed therein, and movable blocks 14 are slidably connected to the two movable grooves 13 .

[0045] One end of the two moving blocks 14 is rotatably connected to one end of the two limiting pins 12 , and the other end of the two moving blocks 14 is arc-shaped.

[0046] One end of the moving block 14 is in an arc shape that matches one side of the limiting block 10 .

[0047] One end of the moving block 14 is fixedly connected to an anti-skid pad 15 , and the anti-skid pad 15 is made of rubber material.

[0048] The anti-skid pad 15 is used to increase the friction between the moving block 14 and the limiting block 10 , thereby increasing the fixing effect of the moving block 14 .

[0049] The working principle of the loudspeaker diaphragm provided by the utility model which is easy to install is as follows:

[0050] When in use, the diaphragm 7 is protected by the dustproof net 8. When the dustproof net 8 needs to be removed for replacement or cleaning, the two limit pins 12 are rotated to one side, so that they move to one side inside the two limit holes 11 respectively. When the two limit pins 12 move to one side, they drive the two moving blocks 14 to move to one side inside the two moving grooves 13 respectively. When one end of the two moving blocks 14 is separated from the surface of the two limit blocks 10 respectively, the dustproof net 8 is rotated to one side to drive the two limit blocks 10 to move to the appropriate position inside the two limit grooves 9 respectively. After the dustproof net 8 is moved upward to drive the two limit blocks 10 to separate from the two limit grooves 9, the dustproof net 8 can be removed.

[0051] When installing a new dustproof net 8, after inserting the two limit blocks 10 on the surface of the dustproof net 8 into the two limit grooves 9, the dustproof net 8 is rotated to one side to a suitable position, and then the two limit pins 12 are reversed to drive the two moving blocks 14 to move to one side until they contact the surfaces of the two limit blocks 10 respectively, so as to limit the dustproof net 8.

[0052] Compared with the related art, the speaker diaphragm provided by the utility model which is easy to install has the following beneficial effects:

[0053] The utility model provides a loudspeaker diaphragm that is easy to install. The diaphragm 7 is protected by a dustproof net 8, thereby preventing dust from adhering to the surface of the diaphragm 7, which would be inconvenient for subsequent cleaning, and preventing dust from adhering to the surface of the diaphragm 7 and affecting the quality of the speaker sound.
