Description

Technical Field

[0001] The present application relates to the technical field of temperature detection, and in particular to a temperature detection device for a speaker. Background Art

[0002] As an important audio output device, speakers are widely used in various electronic products.

[0003] At present, the speaker mainly includes a rear shell, a basin frame, a diaphragm, a magnetic mechanism and a coil. The rear shell and the basin frame are coaxially assembled, the diaphragm is located in the basin frame, the magnetic mechanism is located in the rear shell, and the voice coil is located in the magnetic field of the magnetic mechanism and is connected to the diaphragm. When the speaker inputs an audio current, the audio current is input into the voice coil, and the voice coil vibrates due to the magnetic field of the magnetic mechanism. The voice coil pushes the diaphragm to drive the air to vibrate, thereby producing sound.

[0004] During the use of the speaker, the voice coil will generate heat, which will cause the temperature of the speaker to rise. The high temperature will affect the performance of the speaker and even cause damage to the speaker. In particular, for speakers with high power, long operating time or high working environment temperature, such as large speakers, industrial speakers and car speakers, it is easy for the temperature to be too high, which can easily cause speaker failure problems, so the setting of temperature detection equipment is particularly important. In order to solve this problem, the above-mentioned type of speakers are generally medium and large speakers, and will have built-in temperature detection equipment. The temperature detection equipment often uses a temperature sensor. The temperature sensor is built into the speaker and monitors the temperature of the speaker in real time. When the temperature of the speaker is too high, the speaker will be suspended or an alarm signal will be issued.

[0005] Since the existing temperature detection equipment is generally built into the speaker, when the temperature detection equipment is damaged, the entire speaker needs to be disassembled and then replaced with a new temperature detection equipment or the temperature detection equipment needs to be repaired. During this process, physical damage is easily caused to the speaker, thereby affecting the sound quality and service life of the speaker. Summary of the invention

[0006] The present application provides a temperature detection device for a speaker, the purpose of which is to reduce the impact of disassembly or replacement of the temperature detection device on the speaker itself, thereby ensuring the sound quality and service life of the speaker.

[0007] The temperature detection device of a speaker provided in the present application adopts the following technical solution: A temperature detection device for a loudspeaker comprises a temperature measuring ring shell for being sleeved on a rear shell body of the loudspeaker; a mounting mechanism comprising a plurality of mounting base rods, the mounting base rods being arranged on the outside of the temperature measuring ring shell and being detachably connected to the temperature measuring ring shell, the mounting base rods being arranged along the axial direction of the temperature measuring ring shell in the length direction, and a plurality of the mounting base rods being arranged in sequence and spaced apart along the circumferential direction of the temperature measuring ring shell; a detection mechanism comprising a first temperature sensor, a plurality of the first temperature sensors being arranged on the mounting base rod; a plurality of first long holes being opened on the temperature measuring ring shell, the first long holes being arranged in one-to-one correspondence with the mounting base rods, a plurality of the first temperature sensors on the mounting base rods being plugged into and matched with the corresponding first long holes, and a detection end of the first temperature sensor being arranged toward the central axis of the temperature measuring ring shell.

[0008] By adopting the above technical solution, the temperature measuring ring shell, the installation mechanism and the detection mechanism are arranged in coordination, and the installation mechanism is arranged by installing the base rod, so that the first temperature sensor in the detection mechanism can be installed on the temperature measuring ring shell, which makes it possible for several first temperature sensors to detect the temperature of the rear shell of the speaker, thus satisfying the function of the temperature detection device of the speaker.

[0009] Since the temperature measuring ring shell is provided with the first long hole, the detection end of the first temperature sensor can be arranged directly facing or in contact with the rear shell through the first long hole, which can improve the accuracy of the speaker temperature detection result.

[0010] Since the mounting base rod and the temperature measuring ring shell are detachably connected, it is convenient to remove the mounting base rod and the first temperature sensors corresponding to the mounting base rod from the temperature measuring ring shell for replacement. At the same time, since the temperature measuring ring shell is sleeved on the rear shell of the speaker, it is convenient to install the entire temperature measuring ring shell on the rear shell, and also convenient to remove the entire temperature measuring ring shell from the rear shell.

[0011] By coordinating the temperature measuring ring shell and the mounting base rod, the first temperature sensor is not directly connected to the speaker, which can reduce the impact of disassembly and assembly of the first temperature sensor and the entire temperature detection device on the speaker, thereby ensuring the sound quality or service life of the speaker.

[0012] Optionally, a plurality of long installation grooves are provided on the outer wall of the temperature measuring ring shell, and the long installation grooves are arranged in a one-to-one correspondence with the installation base rods, and the installation base rods are plugged into the corresponding long installation grooves; the long installation grooves are arranged in a one-to-one correspondence with the first long holes, and the first long holes are opened at the bottom of the corresponding long installation grooves.

[0013] By adopting the above technical scheme, the installation long groove is opened, so that the installation base rod is plugged into the corresponding installation long groove, which can realize the detachable connection between the temperature measuring ring shell and the installation base rod, and because the first long hole is opened at the bottom of the installation long groove, when the installation base rod is installed in the corresponding installation long groove, the first temperature sensors on the installation base rod will be automatically inserted into the corresponding first long hole, which can improve the convenience of installing the first temperature sensor and the installation base rod on the temperature measuring ring shell, and thus can also improve the convenience of replacing the first temperature sensor.

[0014] Optionally, one end of the mounting base rod is rotatably and detachably connected to the temperature measuring ring shell, and the other end is snap-fitted with the temperature measuring ring shell.

[0015] By adopting the above technical solution, since one end of the mounting base rod is rotatably connected to the temperature measuring ring shell and the other end is clamped with the temperature measuring ring shell, when the first temperature sensor needs to be replaced, the corresponding mounting base rod can be directly rotated from the temperature measuring ring shell, which makes it convenient to disassemble and assemble the first temperature sensor on the corresponding mounting base rod, and after disassembling and assembling the first temperature sensor, it is also convenient to quickly reinstall the mounting base rod to the temperature measuring ring shell, which makes it convenient to quickly restore the function of the temperature detection equipment.

[0016] On this basis, since the mounting base rod is rotatably connected to the temperature measuring ring shell and is detachably connected, the entire mounting base rod can be disassembled, thereby facilitating direct replacement of the entire mounting base rod. When multiple first temperature sensors on the same mounting base rod are damaged, a new mounting base rod is directly replaced, and the multiple first temperature sensors on the new mounting base rod work normally, which can quickly restore the function of the temperature detection device.

[0017] Optionally, a rotating connection assembly is provided at one end of the mounting base rod, and the rotating connection assembly includes a rotating shaft, the axial direction of the rotating shaft is arranged along the width direction of the mounting base rod, a first rotating hole is opened on the mounting base rod, and a second rotating hole is opened on the inner side wall of the mounting long groove, two ends of the rotating shaft are respectively plugged into the first rotating hole and the second rotating hole, and the rotating shaft is rotatably connected to the inner side wall of the second rotating hole; a pushing drive member is provided on the mounting base rod, the pushing drive member is connected to the rotating shaft, and the pushing drive member is used to drive the rotating shaft to move along its own axial direction.

[0018] By adopting the above technical solution, the rotating connection assembly is provided through the rotating shaft and the driving member. When the driving member drives the rotating shaft to be inserted into the second rotating hole, the mounting base rod can rotate with the rotating shaft as the central axis, thereby meeting the rotating connection requirement between the mounting base rod and the temperature measuring ring shell. When the driving member drives the rotating shaft to be pulled out of the second rotating hole, the mounting base rod can be pulled out of the corresponding mounting long groove. Therefore, the provision of the rotating connection assembly realizes the requirement that one end of the mounting base rod is rotatably connected and detachably connected to the temperature measuring ring shell.

[0019] Optionally, the pushing drive member includes a push plate and a first spring, the push plate is slidably connected to the mounting base rod along the axial direction of the rotating shaft, and the push plate is connected to the rotating shaft; the first spring is located in the first rotating hole, one end of the first spring is connected to the rotating shaft, and the other end is connected to the inner wall of the first rotating hole.

[0020] By adopting the above technical solution, the push drive assembly is pushed through the setting of the push plate. Since the push plate is connected to the rotating shaft, when the push plate is manually pushed, the rotating shaft can be driven to move along its own axial direction, which satisfies the function of the push drive member. The setting of the first spring, when the force applied to the push plate is released, the first spring will automatically push the rotating shaft to reset, so that the mounting base rod and the temperature measuring ring shell are in a rotationally connected state under normal circumstances, which can improve the stability of the mounting base rod installation.

[0021] Optionally, a rotating clamping assembly is provided at one end of the mounting base rod, and the rotating clamping assembly includes a clamping column and a second spring, the clamping column is axially arranged along the width direction of the mounting base rod, a clamping hole is provided on the inner side wall of the mounting long groove, the clamping column is plug-fitted into the clamping hole, and the clamping column is slidably connected to the inner side wall of the clamping hole along its own axial direction; the second spring is located in the clamping hole, one end of the second spring is connected to the clamping column, and the other end is connected to the inner side wall of the clamping hole; a spherical head is provided on the side of the clamping column facing the mounting base rod, and the spherical head is in contact with the side wall of the mounting base rod.

[0022] By adopting the above technical solution, the rotating clamping assembly is arranged through the coordination of the clamping column, the second spring and the spherical head. When the mounting base rod is installed in the corresponding mounting long groove, the mounting base rod will contact the ball head surface, which makes the clamping column shrink into the corresponding clamping hole, and also makes the mounting base rod able to be normally inserted into the mounting long groove. On this basis, under the action of the second spring, when the mounting base rod is fully inserted into the mounting long groove, the ball head surface will contact the side wall of the mounting base rod, thereby clamping the mounting base rod, thereby improving the stability of the installation of the mounting base rod and the temperature measuring ring shell.

[0023] Optionally, a fit adjustment component is provided on the mounting base rod, and the fit adjustment component includes a mounting long plate, and the mounting long plate is located on the side of the mounting base rod facing away from the temperature measuring ring shell, and the mounting base rod is parallel to and spaced apart from the mounting long plate, and a plurality of the first temperature sensors are all arranged on the corresponding mounting long plate; a spacing adjustment piece is provided on the mounting base rod, and the spacing adjustment piece is connected to the corresponding mounting long plate, and the spacing adjustment piece is used to drive the mounting long plate to move toward or away from the mounting base rod.

[0024] By adopting the above technical solution, the fitting adjustment component realizes the installation of a plurality of first temperature sensors on the mounting base rod through the mounting long plate. Since the mounting long plate is arranged parallel and spaced with the corresponding mounting base rod, the detection adjustment member can adjust the distance between the mounting long plate and the mounting base rod, so that after the mounting base rod is installed on the temperature measuring ring shell, the first temperature sensor is inserted into the corresponding first long hole, and the position between the mounting long plate and the mounting base rod is adjusted by the detection adjustment member at this time, so that the detection end of the first temperature sensor can be adjusted to move closer to or away from the central axis of the temperature measuring ring shell.

[0025] Under the action of the fitting adjustment component, when the temperature measuring ring shell is sleeved onto the rear shell body, the detection ends of the first temperature sensors can be adjusted to fit the rear shell body, which can improve the accuracy of the temperature detection result.

[0026] Optionally, the first temperature sensor is slidably connected to the corresponding mounting long plate along the axial direction of the temperature measuring ring shell; the length direction of the first long hole is arranged along the axial direction of the temperature measuring ring shell, and the first temperature sensors are spaced apart or slidably connected to the inner side wall of the corresponding first long hole.

[0027] By adopting the above technical solution, since the first temperature sensor is slidably connected to the mounting long plate, the position of the first temperature sensor can be adjusted along the length direction of the temperature measuring ring shell. Therefore, the position of the first temperature sensor is adjusted according to actual needs, so that the first temperature sensor can detect the temperature at different positions on the rear shell body, thereby ensuring the accuracy of the final detection result. This can also improve the application scope of the temperature detection equipment.

[0028] Optionally, the temperature measuring ring shell includes a fixing ring and a mounting tube, and several mounting base rods are arranged on the outside of the mounting tube. The fixing ring is coaxially rotatably connected to the mounting tube, and several connecting parts are arranged on the inner side wall of the fixing ring. The several connecting parts are arranged in sequence at intervals along the circumference of the fixing ring, and the connecting parts are used for detachable connection with the rear shell of the speaker.

[0029] By adopting the above technical solution, the temperature measuring ring shell is arranged by the cooperation of the fixing ring and the mounting tube, and the fixing ring can be connected to the rear shell of the speaker through a connecting piece. Since the mounting tube is rotatably connected to the fixing ring, the mounting tube and the fixing ring are sleeved on the rear shell, and the fixing ring is connected to the rear shell through a connecting piece. At this time, the mounting tube can be rotated, so that the first temperature sensor can move circumferentially along the mounting tube, and the position of the first temperature sensor can be adjusted, so that the first temperature sensor can detect the temperature at different positions on the rear shell, thereby ensuring the accuracy of the final detection result. This can also improve the application range of the temperature detection equipment.

[0030] Optionally, a heat dissipation mechanism is further included, which includes a plurality of heat dissipation seats, which are arranged on the outside of the temperature measuring ring shell, and the plurality of heat dissipation seats are arranged in sequence and spaced apart along the circumference of the temperature measuring ring shell; the heat dissipation seat includes a heat-conducting base rod, which is detachably connected to the temperature measuring ring shell, and a plurality of heat dissipation fins are arranged on the heat-conducting base rod.

[0031] By adopting the above technical solution, the heat dissipation mechanism is provided with a plurality of heat dissipation seats, and the heat dissipation seat is provided with a heat-conducting base rod and a plurality of heat dissipation fins, which can increase the heat dissipation area, thereby satisfying the heat dissipation function of the heat dissipation seat. By installing a plurality of heat dissipation seats on the temperature measuring ring shell, the heat dissipation capacity of the temperature measuring ring shell can be improved, and the influence of the temperature measuring ring shell on the rear shell of the speaker on the heat dissipation efficiency of the speaker can be reduced.

[0032] In summary, the present application includes at least one of the following beneficial technical effects: 1.

After the mounting base rod 21 is installed, the clamping column 231 automatically contacts the side wall of the mounting base rod 21 under the action of the second spring 232, and the spherical head 234 automatically inserts into the corresponding spherical groove 235, so that the mounting base rod 21 can be clamped, which can improve the convenience and accuracy of the installation of the mounting base rod 21.

[0072] Reference Figure 5 and Figure 6 A fitting adjustment component 24 is also provided on the mounting base rod 21, and the fitting adjustment component 24 includes a mounting long plate 241, the length direction of the mounting long plate 241 is arranged along the length direction of the mounting base rod 21, and the mounting long plate 241 is located on the side of the corresponding mounting base rod 21 away from the mounting tube 12, and a plurality of spacing adjustment members 242 are arranged between the mounting long plate 241 and the corresponding mounting base rod 21.

[0073] In this embodiment, refer to Figure 6 and Figure 7 The interval adjustment member 242 includes a clamping spring 2421 and a clamping bolt 2422. The clamping spring 2421 is sleeved on the outside of the clamping bolt 2422. The clamping spring 2421 is located between the mounting long plate 241 and the corresponding mounting base rod 21, and one end of the clamping spring 2421 is connected to the mounting long plate 241, and the other end is connected to the corresponding mounting base rod 21. The clamping bolt 2422 is rotatably connected to the mounting long plate 241, and the clamping bolt 2422 is axially arranged along the spacing direction between the mounting long plate 241 and the corresponding mounting base rod 21, and one end of the clamping bolt 2422 is threadedly connected to the corresponding mounting base rod 21.

[0074] Under the action of the interval adjustment member 242 , the distance between the installation long plate 241 and the corresponding installation base rod 21 can be adjusted by tightening or loosening the clamping bolt 2422 .

[0075] Reference Figure 6 A plurality of second long holes 211 are provided on the mounting base rod 21 , and the length direction of the second long holes 211 is arranged along the length direction of the mounting base rod 21 , and the plurality of second long holes 211 are arranged in sequence and spaced apart along the length direction thereof.

[0076] Reference Figure 6 A plurality of third long holes 2411 are provided on the mounting long plate 241, and a plurality of third long holes 2411 are provided on the mounting base rod 21. The length direction of the third long holes 2411 is arranged along the length direction of the mounting long plate 241, and the plurality of third long holes 2411 are arranged in sequence and spaced apart along the length direction thereof. A plurality of sliding plates 2412 are provided on the mounting long plate 241, and the sliding plates 2412 are arranged one by one corresponding to the third long holes 411, and the sliding plates 2412 are slidably connected to the inner side walls of the corresponding third long holes 2411 along the length direction of the corresponding third long holes 2411.

[0077] Reference Figure 6The third long hole 2411 is arranged in one-to-one correspondence with the second long hole 211, and the third long hole 2411, the corresponding second long hole 211 and the first long hole 122 are sequentially connected to each other. A plurality of first temperature sensors 31 on the mounting base rod 21 are arranged in one-to-one correspondence with the sliding plate 2412, and the first temperature sensor 31 is connected to the corresponding sliding plate 2412, the first temperature sensor 31 is plugged and matched with the corresponding second long hole 211 and the first long hole 122 in sequence along its own axial direction, the first temperature sensor 31 is detected and set or slidably connected with the inner side wall of the corresponding second long hole 211, and the first temperature sensor 31 is slidably connected or spaced with the inner side wall of the corresponding first long hole 122.

[0078] By installing the long plate 241, the installation of several first temperature sensors 31 on the mounting base rod 21 is realized, and on this basis, the setting of the sliding plate 2412 enables the first temperature sensor 31 to adjust its position along the length direction of the mounting base rod 21, which facilitates the first temperature sensor 31 to measure the temperature at different positions on the speaker. The setting of the interval adjustment member 242 can adjust the distance between the detection end of the first temperature sensor 31 and the rear housing 100 of the speaker, thereby ensuring the detection accuracy.

[0079] Reference Figure 1 and Figure 8 The temperature detection device also includes a heat dissipation mechanism 4, which includes a plurality of heat dissipation seats 41. The heat dissipation seats 41 include a heat-conducting base rod 411, and the heat-conducting base rod 411 is plugged into the installation long groove 121. A plurality of heat dissipation fins 412 are arranged on the side of the heat-conducting base rod 411 away from the installation tube 12.

[0080] In this embodiment, the heat sink 41 and the mounting base rod 21 are alternately arranged in sequence along the circumference of the mounting tube 12, which ensures that the temperature of the speaker rear housing 100 can be detected while the speaker has sufficient heat dissipation capacity.

[0081] Reference Figure 2 and Fig.10 The heat dissipation mechanism 4 further includes a sealing disk 42, which is coaxially arranged with the fixing ring 11 and is located on a side of the fixing ring 11 away from the mounting tube 12, and the sealing disk 42 seals the fixing ring 11. A second temperature sensor 32 is also arranged on the sealing disk 42, and the second temperature sensor 32 is arranged axially along the fixing ring 11, and the detection end of the second temperature sensor 32 is arranged toward the mounting tube 12.

[0082] When the temperature measuring ring shell 1 is installed on the rear housing 100 of the loudspeaker, the detection end of the second temperature sensor 32 can contact the rear housing 100 , which can improve the accuracy of the temperature detection result of the rear housing 100 .

[0083] Reference Fig.10A plurality of automatic heat dissipation components 43 are arranged between the sealing disk 42 and the fixing ring 11 , and the plurality of automatic heat dissipation components 43 are arranged in sequence and spaced apart along the circumference of the sealing disk 42 .

[0084] Reference Fig.10 The automatic heat dissipation component 43 includes an extension plate 431, and the length direction of the extension plate 431 is arranged along the corresponding radial direction of the sealing disk 42, and one end of the extension plate 431 is connected to the sealing disk 42 by bolts, and the other end extends in a direction away from the sealing disk 42.

[0085] Reference Fig.10 The automatic heat dissipation assembly 43 further includes a push rod 432, an automatic spring 433 and a heat expansion block 434. The push rod 432 is axially arranged parallel to the axial direction of the fixing ring 11. A push hole is provided on the end surface of the fixing ring 11 away from the mounting tube 12. The push rod 432 is coaxially plugged with the push hole, and the push rod 432 is slidably connected to the inner side wall of the push hole along its own axial direction. One end of the push rod 432 is connected to the corresponding extension plate 431. The heat expansion block 434 is located in the push hole, and the heat expansion block 434 is located at one end of the push rod 432 away from the corresponding extension plate 431, and the push rod 432 is connected to the heat expansion block 434. The automatic spring 433 is located in the push hole, and the automatic spring 433 is sleeved on the outside of the push rod 432, and one end of the automatic spring 433 is connected to the push rod 432, and the other end is connected to the inner side wall of the push hole. In this embodiment, the heat expansion block 434 is made of heat expansion material.

[0086] When the temperature of the speaker is too high, the heat expansion block 434 expands due to the heat. After the heat expansion block 434 expands, it pushes the push rod 432 to move, so that the sealing disk 42 opens the fixed ring 11, thereby improving the heat dissipation capacity of the speaker. In addition, as the temperature rises, the expansion size of the heat expansion block 434 is different, which can open the sealing disk 42 and the fixed ring 11 to different sizes, thus meeting different heat dissipation requirements. After the temperature of the speaker drops, the heat expansion block 434 restores its shape, and the automatic spring 433 pushes the push rod 432 to reset, and the sealing disk 42 re-closes the fixed ring 11.

[0087] The implementation principle of the embodiment of the present application is: when the temperature of the speaker is detected, the temperature measuring ring shell 1 is installed on the rear shell 100 of the speaker. At this time, several first temperature sensors 31 detect the temperature of the peripheral side of the rear shell 100, and the second temperature sensor 32 detects the temperature of the end face of the rear shell 100. This can perform a complete and comprehensive temperature detection on the rear shell 100.

[0088] When the first temperature sensor 31 is damaged, the corresponding mounting base rod 21 is moved away from the end of the fixing ring 11, and the mounting base rod 21 can be rotated out of the corresponding mounting long groove 121, so that the first temperature sensor 31 can be replaced. If the first temperature sensor 31 needs to be replaced quickly, the entire mounting base rod 21 is directly pulled out from the corresponding temperature measuring ring shell 1, and then a new mounting base rod 21 with the first temperature sensor 31 installed is replaced.

The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
