Description

Technical Field

[0001] The utility model relates to the technical field of loudspeaker drivers, in particular to a high-power carbon fiber diaphragm driver. Background Art

[0002] A diaphragm driver is a device that converts electrical signals into sound. It is usually used in audio devices such as speakers and headphones. Its main function is to generate vibrations, push air, and thus produce sound. The working principle of the diaphragm driver is to convert electrical signals into mechanical vibrations through electromagnetic induction or piezoelectric effect. When the electrical signal passes through the driver, a magnetic field or electric field is generated, causing the diaphragm to vibrate. The vibration frequency and amplitude of the diaphragm are proportional to the frequency and amplitude of the input electrical signal. Therefore, the pitch, volume, timbre and other parameters of the sound can be controlled by changing the frequency and amplitude of the electrical signal.

[0003] Different types of diaphragm drivers have different characteristics and application scenarios. For example, the paper cone diaphragm has a relatively smooth and natural sound characteristic and is often used in mid- and low-end speakers. The metal diaphragm has excellent rigidity and outstanding performance in dynamics and analytical power, but has high requirements on the driving force and control of the unit, and the cost is relatively high. The carbon fiber diaphragm combines the advantages of multiple materials and is often used in high-end speakers. In general, the diaphragm driver is a very important component of audio equipment, and its performance and quality directly affect the quality and effect of the sound.

[0004] The prior art includes a utility model with a publication number of CN216086999U. The utility model relates to a high-power compression driver with high efficiency, heat dissipation and no sound loss. A built-in sound diaphragm is fixedly pressed between the upper and lower cylinders. The upper and lower cylinders are respectively one-piece die-cast aluminum structures with heat dissipation fins evenly distributed on the outer walls. A groove is provided on the upper end face of the lower cylinder to embed a U-iron. The U-iron embeds a magnetic steel and a lower pole plate. A voice coil is provided on the outer wall of the lower pole plate. The phase plug under the sound diaphragm is supported on the lower pole plate. The cone head of the phase plug faces the center of the lower cylinder and the sound channel opened at the lower end of the lower cylinder. A cavity is left between the sound diaphragm and the inner cavity of the upper cylinder. The structure is simple and compact, and can conduct and cool the internal heat well, ensuring the use power and service life, and solving the problem that the high-frequency vibration heating phenomenon inside the driver is becoming more and more obvious, which directly leads to partial power loss, and long-term use of high temperature is prone to cause magnetic field loss to the internal magnetic steel magnetic circuit structure, which directly affects the use performance and service life.

[0024] See also Figure 1-5 The utility model provides a technical solution: a high-power carbon fiber diaphragm driver, including a driver body 1 and a protective device 4, a sound channel body 3 is arranged on the surface of the driver body 1, an end piece 2 is arranged on the surface of the driver body 1, and the protective device 4 is arranged on the surface of the end piece 2.

[0025] The specific configuration and function of the protective device 4 and the connecting assembly 44 will be described in detail below.

[0026] Specifically, the protective device 4 includes an end cover 41, which is arranged on one side of the end piece 2. A connecting component 44 is arranged on the surface of the end cover 41. The end cover 41 is installed on the end piece 2 through the connecting component 44. A sliding cavity is opened on the inner wall of the end cover 41, and a slider 43 is slidably connected to the inner wall of the sliding cavity. The side of the slider 43 corresponding to the inner wall of the sliding cavity on the surface of the end cover 41 is fixedly connected with an elastic cloth 42.

[0027] In this embodiment: when the driver body 1 is not in use, the slider 43 and the elastic cloth 42 can be pushed in the sliding cavity on the surface of the end cover 41, and the elastic cloth 42 is then unfolded to shield the speaker channel body 3, thereby reducing the entry of dust and impurities into the speaker channel body 3, affecting the sound quality and causing subsequent inconvenience in cleaning.

[0028] Specifically, a push rod 48 is fixedly connected to the surface of the slider 43, and a groove 47 is opened on the surface of the end cover 41 for the push rod 48 to be inserted into. The push rod 48 can control the movement of the slider 43. When the push rod 48 drives the slider 43 and the elastic cloth 42 to reset, the push rod 48 can be inserted into the groove 47.

[0029] Specifically, the inner wall of the end cover 41 is threadedly connected with two screws 45, and the surface of the slider 43 is provided with two positioning holes. The screws 45 are plugged into the inner walls of the positioning holes. When the push rod 48 drives the slider 43 to unfold the elastic cloth 42, the screws 45 are rotated and inserted into the positioning holes on the surface of the slider 43, thereby limiting the slider 43 and the elastic cloth 42.

[0030] Specifically, one end of the screw rod 45 is fixedly connected to an anti-drop rope 46 , and the other end of the anti-drop rope 46 is fixedly connected to the surface of the end cover 41 .

[0031] Specifically, the connecting component 44 includes three plug rods 444, and the three plug rods 444 are rotatably connected to the inner wall of the end cover 41. One end of the plug rod 444 is fixedly connected to a stopper 445. Three groups of circular holes 441 are provided on the surface of the end piece 2, and a through hole 442 is provided on the side surface of the end piece 2 close to the circular hole 441. The circular hole 441 and the through hole 442 are respectively used for the plug rod 444 and the stopper 445 to pass through.

[0032] In this embodiment: the insertion rod 444 and the stopper 445 are inserted into the circular hole 441 and the through hole 442 on the surface of the end piece 2, and then the insertion rod 444 and the stopper 445 are rotated, and the stopper 445 abuts against the other side surface of the end piece 2 to complete the connection, which is convenient for subsequent disassembly and cleaning.

[0033] Specifically, one end of the insertion rod 444 is fixedly connected to a rotating cap 443, and the rotating cap 443 facilitates the control of the rotation of the insertion rod 444 and the stopper 445.

[0034] Specifically, a magnetic ring 1 446 is fixedly connected to the inner wall of the rotating cap 443 , and a magnetic ring 2 447 is fixedly connected to the inner wall of the end cover 41 . The magnetic ring 1 446 and the magnetic ring 2 447 are magnetically connected.

[0035] In this embodiment: the magnetic ring 1 446 cooperates with the magnetic ring 2 447 to position the rotating cap 443 and the insert rod 444, thereby improving the abutment effect between the stopper 445 and the end piece 2.

[0036] Working principle: the driver body 1 generates sound by generating vibration, and the sound is emitted through the sound channel body 3. By setting the protective device 4 and the connecting component 44, the end cover 41 is placed on the end piece 2, and the plug rod 444 and the stopper 445 are inserted into the circular hole 441 and the through hole 442 on the surface of the end piece 2. Then, the rotating cap 443 is rotated, and the rotating cap 443 drives the plug rod 444 and the stopper 445. The stopper 445 is against the other side surface of the end piece 2. The magnetic ring 1 446 and the magnetic ring 2 447 attract each other to limit the rotating cap 443 and the plug rod 444, and the connection is completed. When the driver body 1 is not used for a long time, the push rod 48 and the slider 43 are pushed, and the slider 43 drives the elastic cloth 42 to unfold in the sliding cavity of the end cover 41. When the slider 43 moves to a point where it cannot move, the screw 45 is rotated and the screw 45 can be inserted into the positioning hole on the surface of the slider 43. At this time, the elastic cloth 42 can prevent dust from entering the speaker channel body 3. By setting the protective device 4, the dust can enter the speaker channel in the high-power carbon fiber diaphragm driver to affect the propagation of sound, so that the sound can be output more clearly and purely. This can effectively reduce the risk of a large amount of dust entering the speaker channel of the existing high-power carbon fiber diaphragm driver when it is not used for a long time, interfering with the propagation of sound and causing the sound to become unclear. The dust can also generate unnecessary noise when the diaphragm vibrates, thereby reducing the erosion and wear of the diaphragm and other components by dust, thereby improving the overall usability of the device.
