Description

Technical Field

[0001] This utility model relates to the field of loudspeaker technology, and in particular to a loudspeaker structure for a home audio device. Background Technology

[0002] A loudspeaker is a transducer that converts electrical signals into sound signals, and its performance greatly affects sound quality. While the loudspeaker is the weakest component in an audio system, it is also one of the most crucial for achieving optimal sound effects. Audio electrical energy, through electromagnetic, piezoelectric, or electrostatic effects, causes the cone or diaphragm to vibrate and resonate with the surrounding air, thus producing sound.

[0003] The working principle of a loudspeaker is based on electromagnetic induction. When an audio signal is input to the loudspeaker, the change in the signal causes a change in the current passing through the voice coil. The voice coil interacts with the magnetic force of the magnet in the magnetic field, generating a change in force that drives the diaphragm to vibrate. The vibration of the diaphragm transmits pressure waves to the surrounding air, forming sound waves. These sound waves propagate through the air and are eventually received by the ear and converted into audible sound. However, loudspeakers are difficult to clean and maintain, allowing dust and impurities to enter the loudspeaker and affect sound quality. Therefore, a loudspeaker structure for home audio equipment is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a speaker structure for home audio equipment, aiming to improve the problem of difficult cleaning and maintenance of speakers in the prior art, which leads to dust and impurities entering the speaker and affecting sound quality.

[0006] As a further description of the above technical solution:

[0007] An inner panel is fixedly connected to the front side of the box, and an inner frame is fixedly connected to the inner side of the front shell. Insert rods are fixedly connected to all four sides of the side of the front shell that is close to the box. Insert holes are opened on all four sides of the side of the box that is close to the front shell, and the insert rods are engaged and connected inside the insert holes.

[0008] As a further description of the above technical solution:

[0009] The positioning component includes a spring, one end of which is fixedly connected to the inner wall of the through groove, and the other end of which is fixedly connected to a positioning head, which is slidably connected inside the positioning hole.

[0010] As a further description of the above technical solution:

[0011] The positioning head is slidably connected inside the through groove.

[0012] As a further description of the above technical solution:

[0013] Each of the four corners on one side of the inner frame is fixedly connected with a clip, and the protruding end of the clip hooks the inner plate.

[0014] As a further description of the above technical solution:

[0015] The box body, inner panel and inner frame each have two mounting holes on the upper and lower sides, and bolts are threaded into the mounting holes.

[0016] As a further description of the above technical solution:

[0017] The inner frame and the front shell form a slot, and the inner plate is engaged and connected inside the slot.

[0018] This utility model has the following beneficial effects:

[0019] 1. In this utility model, by clipping the protective shell onto the outside of the speaker body, the positioning head is squeezed as the protective shell moves, causing it to simultaneously squeeze the spring and generate a rebound force. When one side of the protective shell is in contact with the front shell, the positioning head is no longer squeezed, allowing it to be inserted into the positioning hole under the rebound force of the spring. This achieves a secure installation of the protective shell, ensuring protection of the diaphragm inside the speaker body and preventing dust from entering and affecting the speaker's sound effect.

[0020] 2. In this utility model, after the speaker body is installed on the front shell, the plug rod is aligned with the plug hole and inserted to make the front shell fit against the cabinet. At the same time, the inner plate is inserted into the slot. When the inner plate is fully inserted, the clip hooks the inner plate to lock and fix the front shell. Then, the bolt is screwed into the mounting hole to further tighten the front shell. This realizes convenient installation, disassembly and fastening of the speaker as a whole, so as to reduce maintenance time. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figure 2 , Figure 4 , Figure 6 This utility model provides an embodiment of a speaker structure for a home audio device, including a housing 1, a front shell 3 installed on the front side of the housing 1, a speaker body 11 installed inside the front shell 3, a protective shell 12 snapped onto the front exterior of the speaker body 11, through grooves 13 formed around the inner perimeter of the protective shell 12, a positioning component fixedly connected inside the through grooves 13, the positioning component being used to securely fix the protective shell 12 onto the outside of the speaker body 11, and positioning holes 16 formed around the inner perimeter of the speaker body 11 corresponding to the number and position of the through grooves 13; the positioning component includes a spring 14, one end of the spring 14 fixedly connected to the inner wall of the through groove 13, and the other end of the spring 14 fixedly connected to a positioning head 15, the positioning head 15 being slidably connected inside the positioning holes 16 and the through groove 13.

[0031] By attaching the protective shell 12 to the outside of the speaker body 11, the positioning head 15 is compressed as the protective shell 12 engages. Simultaneously, the positioning head 15 is compressed, which in turn compresses the spring 14, generating a rebound force. When one side of the protective shell 12 is in contact with the front shell 3, the positioning head 15 is no longer compressed. Under the rebound force of the spring 14, it is pushed into the positioning hole 16, thus achieving a secure installation of the protective shell 12. This ensures protection of the diaphragm inside the speaker body 11, preventing dust from entering and affecting the speaker's sound effect.

[0032] Reference Figure 1 , Figure 3 , Figure 5 The inner panel 2 is fixedly connected to the front side of the box body 1. The inner frame 4 is fixedly connected to the inner side of the front shell 3. Insert rods 6 are fixedly connected to the four sides of the side of the front shell 3 that is close to the box body 1. Insert holes 7 are opened on the four sides of the side of the box body 1 that is close to the front shell 3. Insert rods 6 are engaged and connected to the inside of the insert holes 7. The four corners of one side of the inner frame 4 are fixedly connected to the clips 8. The protruding end of the clips 8 hooks the inner panel 2. Two mounting holes 10 are opened on the upper and lower sides of the box body 1, the inner panel 2 and the inner frame 4. Bolts 9 are threaded inside the mounting holes 10. The inner frame 4 and the front shell 3 form a groove 5. The inner panel 2 is engaged and connected to the inside of the groove 5.

[0033] After the speaker body 11 is installed on the front shell 3, the plug rod 6 is aligned with the plug hole 7 and inserted to make the front shell 3 fit against the cabinet 1. At the same time, the inner plate 2 is inserted into the slot 5. When the inner plate 2 is fully inserted into the slot 5, the protruding end of the clip 8 holds the inner plate 2 in place, thus locking and fixing the front shell 3. Then, the bolt 9 is screwed into the mounting hole 10 to further tighten and fix the front shell 3. This allows for convenient installation, disassembly and fastening of the speaker as a whole, thereby reducing maintenance time.

[0034] Working principle: When the device is needed, after the speaker body 11 is installed on the front shell 3, the plug rod 6 is aligned with the plug hole 7 and inserted, so that the front shell 3 is close to the cabinet 1. At the same time, the inner plate 2 is inserted into the slot 5. When the inner plate 2 is fully inserted, the clip 8 hooks the inner plate 2 to lock and fix the front shell 3. Then, the bolt 9 is screwed into the mounting hole 10 to further tighten the front shell 3. This realizes convenient installation, disassembly and tightening of the speaker body, so as to reduce maintenance time. By clamping the protective shell 12 on the outside of the speaker body 11, when the protective shell 12 moves, it squeezes the positioning head 15, which simultaneously squeezes the spring 14 to generate a rebound force. When one side of the protective shell 12 is close to the front shell 3, the positioning head 15 is no longer squeezed, and it is inserted into the positioning hole 16 under the rebound force of the spring 14. This realizes the tight installation of the protective shell 12, ensuring the protection of the diaphragm inside the speaker body 11 and preventing dust from entering the interior and affecting the sound effect of the speaker.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
