Description

Technical Field

[0001] The utility model relates to the technical field of loudspeakers, in particular to a loudspeaker with a shell that is easy to replace. Background Art

[0002] Speakers, commonly known as "horns", are transducers that convert electrical signals into sound signals. The performance of speakers has a great impact on the sound quality. Speakers are the weakest component in audio equipment, but they are the most important component for sound effects. There are many types of speakers, and their prices vary greatly. Audio power vibrates the cone or diaphragm through electromagnetic, piezoelectric or electrostatic effects, and resonates (resonates) with the surrounding air to produce sound. At present, speakers are widely used in audio equipment, and the shell will inevitably be damaged during long-term use. Damage to the shell will cause the speaker to make a lot of noise, and when the shell needs to be replaced, the corresponding model is required for installation, and many models are difficult to match, making the internal speakers abandoned, greatly wasting the use of the speakers. Utility Model Content

[0004] A speaker with an easily replaceable shell comprises: a shell, a limiting mechanism is arranged inside the shell, a speaker is plugged into the middle of the limiting mechanism; the limiting mechanism comprises a limiting plate, a plug-in slot is arranged in the middle of the limiting plate, connecting seats are arranged at four corners of the lower end of the limiting plate, and support columns are screwed inside the connecting seats; the speaker comprises an iron core, a basin frame is connected to the upper end of the iron core, a pressing edge is connected to the upper periphery of the basin frame, a clamping groove is arranged inside the pressing edge, an elastic sheet is installed inside the clamping groove, and a support ring is clamped inside the clamping groove.

[0005] As an improvement of the above technical solution, the side edge of the limiting plate is also clamped with an extension strip for extending the side edge structure.

[0006] As an improvement of the above technical solution, the basin frame is connected to the upper end limit plate of the plug-in slot in the middle part of the limit plate through a pressing edge.

[0007] As an improvement of the above technical solution, a magnet is sleeved on the surface of the iron core, a paper basin is sleeved on the inner wall of the basin frame, and a plurality of groups of evenly distributed protective pads are arranged on the upper end of the support ring.

[0008] As an improvement of the above technical solution, a convex ridge which is limitedly engaged with the inside of the engaging groove is provided on the side of the lower end of the support ring.

[0009] Beneficial effects of the utility model:

[0010] The limit plate that is set can be used to fix the original shell when it is replaced after being damaged after the speaker is installed, and cooperate with the support column screwed on the connecting seat to support the replaced shell. At the same time, the support column can be manually adjusted to change the height, which satisfies the function of stable support after replacing different shells. At the same time, the elastic sheet and the clamping support ring are installed in the clamping groove inside the pressing edge, so that the upper cover can be used to press down and limit after installing inside different shells, so as to avoid the speaker shaking inside the shell and causing damage due to the difference in shells.

[0018] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0019] Example

[0020] A speaker with a housing that is easy to replace, comprising:

[0021] A housing 1, a limit mechanism 2 is arranged inside the housing 1, and a speaker 3 is plugged into the middle of the limit mechanism 2;

[0022] The limiting mechanism 2 comprises a limiting plate 21, a plug-in slot 22 is provided in the middle of the limiting plate 21, and connecting seats 23 are provided at the four corners of the lower end of the limiting plate 21, and a supporting column 24 is screwed inside the connecting seat 23;

[0023] The limit plate 21 provided can fix the original shell when it is replaced after being damaged, and the support columns 24 are screwed to the connecting seats 23 provided at the four corners of the lower end, so that the support columns 24 can be freely replaced according to the different depths of the shell 1, so that it can be more stable when supporting upward, and because the support columns 24 are screwed to the connecting seat 23, manual adjustment can be performed due to the unevenness inside the shell 1, which satisfies the function of stable support after replacing different shells 1, and the plug-in slot 22 opened in the middle can make it more convenient to plug and install the speaker 3 to avoid falling off during use.

[0024] As an improvement of the above technical solution, the side of the limiting plate 21 is also clamped with an extension strip 25 for extending the side structure. When replacing a different shell 1, the side of the limiting plate 21 can be clamped with the extension strip 25 according to the diameter of the shell 1, so that it is convenient to clamp it inside the shell 1, avoiding damage to the internal speaker 3 due to shaking during use, and further improving the stability after installation.

[0025] The speaker 3 includes an iron core 31, a basin frame 33 is connected to the upper end of the iron core 31, a pressing edge 35 is connected to the upper periphery of the basin frame 33, a clamping groove 36 is provided inside the pressing edge 35, an elastic sheet 37 is installed inside the clamping groove 36, a support ring 38 is clamped inside the clamping groove 36, a magnet 32 ​​is sleeved on the surface of the iron core 31, a paper cone 34 is sleeved on the inner wall of the basin frame 33, and a plurality of groups of evenly distributed protective pads 39 are also provided on the upper end of the support ring 38;

[0026] The iron core 31 provided can work in cooperation with the magnet 32 ​​sleeved on the outside, so as to facilitate the normal sound of the speaker 3. At the same time, the paper cone 34 can be installed inside the basin frame 33 provided at the upper end, so that the sound quality of the speaker 3 is better. At the same time, the pressing edge 35 provided at the upper end can be limited when installed with the limiting mechanism 2. At the same time, the clamping groove 36 opened inside, and the elastic sheet 37 is installed inside the clamping groove 36, and the support ring 38 is clamped at the same time, so that after the shell 1 is replaced, the upper cover of the shell 1 can be pressed down to limit the position when installing it according to the difference of the shell 1, and squeezed, so that the speaker 3 as a whole can be fixed against the upper cover of the shell 1, so as to avoid the speaker 3 being shaken inside the shell 1 due to the difference of the shell, and causing damage. At the same time, a protective pad 39 is also provided on the upper end of the support ring 38, which can reduce the vibration of the speaker 3 during installation, avoid the rigid contact between the speaker 3 and the shell 1 and cause damage, and can also further adjust the speaker 3 when changing different heights. Provide support and better stability.

[0027] As an improvement of the above technical solution, the lower side of the support ring 38 is provided with a ridge that is limitedly engaged with the inside of the engaging groove 36, which can limit the support ring 38 after installation to avoid the support ring 38 being ejected and lost due to the internal elastic sheet 37 when not in use.

[0028] In order to facilitate the installation of the speaker 3 inside the limiting mechanism 2 for fixing, the basin frame 33 is sleeved on the upper limit plate 21 of the insertion slot 22 in the middle of the limiting plate 21 through the pressing edge 35, which can fix the speaker 3 when plugged in to avoid falling off due to shaking during use.

[0029] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
