Description

Technical Field

[0001] The present invention relates to the technical field of speakers, and specifically to a speaker durability testing device and a testing method. Background Technique

[0002] Speakers are divided into two categories: musical instruments and electroacoustic components. Electroacoustic components convert electrical signals into sounds. To ensure the quality of speakers, during the production of speakers, it is necessary to monitor and test the quality of speakers. One of the test items includes durability testing, and the durability of speakers is detected through a durability testing device.

[0003] For example, a speaker durability testing bench with the publication number CN208891073U has a button provided at the upper end of the outer surface of the speaker. A contact block is fixedly connected to the outer surface of the second rotating rod. The lower end of the outer surface of the contact block is movably connected to the button. When the contact block touches the button, the speaker emits a beeping sound.

[0004] The above-mentioned speaker durability testing device conducts durability testing on the speaker by continuously pressing the contact block. Since the distance of the up and down pressing of the contact block is fixed and the same, after the durability testing of the speaker is completed, the contact block needs to be stopped before the speaker can be replaced. This operation takes a relatively long time and reduces the production efficiency. Summary of the Invention

[0005] The purpose of the present invention is to provide a speaker durability testing device and a testing method to solve the problem proposed in the above background technique that currently in the market, after the durability testing of the speaker is completed, the contact block needs to be stopped before the speaker can be replaced. This operation takes a relatively long time and reduces the production efficiency.

[0006] To achieve the above purpose, the present invention provides the following technical solution: A speaker durability testing device includes a durability testing bench, a display lamp, and a display screen. The display screen is installed on the durability testing bench. Display lamps are installed on the durability testing bench at equal intervals. An installation frame is installed on the durability testing bench. Sockets are opened on the installation frame at equal intervals. A speaker body is inserted into the socket. A connecting plate is inserted into the installation frame. An adjusting mechanism is provided on the connecting plate to change the position of the insertion rod and replace the speaker body after the durability experiment is completed.

[0007] Preferably, a support rod is electrically connected to the display lamp. A connecting rod slides inside the support rod. Two contact points are installed at the top of the connecting rod. The connecting rod is electrically connected to the contact points. An electric telescopic rod is installed on the side of the display lamp. The end of the electric telescopic rod is fixed to the connecting rod.

[0008] Preferably, a threaded rod is rotatably connected to the upper side of the connecting plate. The threaded rod is threadedly connected to the connecting plate. An installation rod is inserted into the connecting plate. An insertion rod is installed at one end of the installation rod close to the speaker body. The insertion rod is inserted into the installation hole on the speaker body.

[0009] Preferably, the adjusting mechanism includes a limiting rod, a groove and a push rod. The limiting rods are slidably connected to the connecting plate at equal intervals, and the end of the limiting rod close to the mounting rod is of an inclined structure. A groove is formed at the end of the limiting rod away from the mounting rod, and the inside of the groove is inclined. The length corresponding to the inclined side of the groove is greater than the length corresponding to the inclined side of the limiting rod.

[0010] Preferably, a push rod is slidably connected to the connecting plate. The push rod is of a comb tooth structure. The end of the push rod close to the limiting rod contacts the groove. Connecting springs are installed between the push rod, the limiting rod, the mounting rod and the connecting plate.

[0011] Preferably, the mounting rod contacts the inclined side of the end of the connecting plate. The moving distance of the mounting rod is equal to the width of the limiting rod. Two adjacent connecting rods are installed together.

[0012] A test method for a horn durability test device includes the following steps:

[0013] Step 1: Insert the horn body into the socket. Rotate the threaded rod by hand. The rotation of the threaded rod causes the connecting plate to move towards the side close to the horn body. The movement of the connecting plate drives the mounting rod and the plug rod to move synchronously until the plug rod is inserted into the mounting hole of the horn body.

[0014] Step 2: Start the power supply of the electric telescopic rod. The operation of the electric telescopic rod causes the connecting rod to move. The movement of the connecting rod drives the contact to move synchronously. The electric telescopic rod performs a reciprocating motion. The contact continuously contacts and separates from the joint position of the horn body. When the contact contacts the horn body, the horn body is connected to the circuit and the horn body sounds. When the contact separates from the horn body, the horn body is disconnected from the circuit and the horn body does not sound, simulating the work of a person on the horn body and detecting the durability of the horn body.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. The present invention is provided with an adjusting mechanism, which includes a limiting rod, a groove and a push rod. Pull the limiting rod to separate it from the limiting rod, so that the plug rod is separated from the mounting hole of the horn body, and the horn body can be changed. When changing a certain horn body, other horn bodies can be tested normally, reducing the replacement time and operation steps, and greatly reducing the waste of test time.

[0017] 2. The present invention is provided with a connecting rod and a contact. The movement of the connecting rod drives the contact to move synchronously. Furthermore, multiple contacts can move synchronously. Multiple horn bodies can be connected to the power supply at one time, and multiple horn bodies can be tested at the same time. At the same time, it is not necessary to connect the horn body to other external electronic components, which can greatly improve work efficiency.

[0018] 3. The present invention is provided with a push rod and a groove. The inside of the groove is inclined. The end of the push rod contacts the groove. When all the horn bodies installed on the durability test bench are tested, all the horn bodies can be taken and disassembled, without having to pull the corresponding limit rods on each horn body one by one, reducing the operation steps.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0027] Please refer to Figures 1-6 , the present invention provides a technical solution:

[0028] A loudspeaker durability test device includes a durability test bench 1, display lights 8, and a display screen 3. The display screen 3 is installed on the durability test bench 1, and the display lights 8 are installed on the durability test bench 1 at equal intervals. An installation frame 2 is installed on the durability test bench 1. Socket holes 12 are provided at equal intervals on the installation frame 2. A loudspeaker body 5 is inserted into the socket holes 12. A threaded rod 7 is rotatably connected to the upper side of a connecting plate 6. The threaded rod 7 is threadedly connected to the connecting plate 6. An installation rod 18 is inserted into the connecting plate 6. One end of the installation rod 18 close to the loudspeaker body 5 is provided with a plug rod 11. The plug rod 11 is inserted into the installation hole on the loudspeaker body 5. The connecting plate 6 is inserted into the installation frame 2.

[0029] First, insert the loudspeaker body 5 into the interior of the socket holes 12 to keep the loudspeaker body 5 in a vertical state. Then, rotate the threaded rod 7 by hand. The rotation of the threaded rod 7 causes the connecting plate 6 to move towards the side close to the installation frame 2. The movement of the connecting plate 6 drives the synchronous movement of multiple plug rods 11, so that the plug rods 11 are inserted into the installation holes of the loudspeaker body 5, realizing the fixation of the loudspeaker body 5 and keeping the loudspeaker body 5 stable.

[0030] An adjustment mechanism is provided on the connecting plate 6 to change the position of the plug rod 11 and replace the loudspeaker body 5 after the durability test. The adjustment mechanism includes a limit rod 16, a groove 17, and a push rod 14. The limit rods 16 are slidably connected to the connecting plate 6 at equal intervals, and the end of the limit rod 16 close to the installation rod 18 is of an inclined structure. A groove 17 is provided at the end of the limit rod 16 away from the installation rod 18. The interior of the groove 17 is inclined, and the length corresponding to the inclined side of the groove 17 is greater than the length corresponding to the inclined side of the limit rod 16.

[0031] After the durability tests of several loudspeaker bodies 5 are completed, pull the corresponding limit rod 16 to the side by hand. The limit rod 16 moves horizontally and gradually separates from the installation rod 18. When the installation rod 18 is completely separated from the limit rod 16, the elastic force of the connecting spring 15 causes the installation rod 18 to move outward. The movement of the installation rod 18 drives the movement of the plug rod 11, and the plug rod 11 gradually separates from the installation hole of the loudspeaker body 5. When the installation rod 18 moves to the outermost side, at this time the plug rod 11 is completely separated from the installation hole of the loudspeaker body 5. Then the staff can pull out the loudspeaker body 5 upward, and the loudspeaker body 5 is separated from the installation frame 2. Then insert a new loudspeaker body 5 into the interior of the socket holes 12. Then push the installation rod 18 towards the side of the loudspeaker body 5 by hand. The installation rod 18 moves towards the side close to the loudspeaker body 5. During the movement of the installation rod 18, it pushes the limit rod 16, causing the limit rod 16 to move to the side. When the installation rod 18 moves until it fits the connecting plate 6, the elastic force of the connecting spring 15 causes the limit rod 16 to move in the opposite direction. The limit rod 16 moves until it fits the installation rod 18, and the limit rod 16 limits the installation rod 18. The installation rod 18 causes the plug rod 11 to be inserted into the installation hole of the loudspeaker body 5.

[0032] A push rod 14 is slidably connected to the connecting plate 6. The push rod 14 is of a comb tooth structure. The end of the push rod 14 close to the limiting rod 16 contacts the groove 17. Connecting springs 15 are installed between the push rod 14, the limiting rod 16, the mounting rod 18 and the connecting plate 6. The mounting rod 18 contacts the inclined edge at the end of the connecting plate 6. The moving distance of the mounting rod 18 is equal to the width of the limiting rod 16. Two adjacent connecting rods 4 are installed together.

[0033] After all the horn bodies 5 are tested, push the push rod 14 by hand towards the connecting plate 6. The movement of the push rod 14 pushes the inclined edge of the groove 17. The movement of the push rod 14 causes the limiting rod 16 to move away from the mounting rod 18 until the limiting rod 16 is separated from the mounting rod 18. At this time, the elastic force of the connecting spring 15 causes the mounting rod 18 and the inserting rod 11 to gradually move away from the mounting hole position of the horn body 5, so that all the horn bodies 5 can be moved, and there is no need to operate the parts corresponding to each horn body 5, greatly improving the work efficiency.

[0034] A support rod 9 is electrically connected to the display lamp 8. A connecting rod 4 slides inside the support rod 9. Two contacts 13 are installed at the top of the connecting rod 4. The connecting rod 4 is electrically connected to the contacts 13. An electric telescopic rod 10 is installed on the side of the display lamp 8. The end of the electric telescopic rod 10 is fixed to the connecting rod 4.

[0035] The operation of the electric telescopic rod 10 causes the connecting rod 4 to move back and forth. During the movement of the connecting rod 4, the contacts 13 are driven to move synchronously. The contacts 13 continuously contact and separate from the wiring position of the horn body 5. When the contacts 13 contact the wiring position of the horn body 5, the horn body 5 is powered on and emits a beeping sound, simulating a person pressing the horn body 5.

[0036] A test method for a horn durability test device includes the following steps:

[0037] Step 1: Insert the horn body 5 into the socket 12. Rotate the threaded rod 7 by hand. The rotation of the threaded rod 7 causes the connecting plate 6 to move towards the horn body 5. The movement of the connecting plate 6 drives the mounting rod 18 and the inserting rod 11 to move synchronously until the inserting rod 11 is inserted into the mounting hole of the horn body 5.

[0038] Step 2: Start the power supply of the electric telescopic rod 10. The operation of the electric telescopic rod 10 causes the connecting rod 4 to move. The movement of the connecting rod 4 drives the contacts 13 to move synchronously. The electric telescopic rod 10 performs a reciprocating motion. The contacts 13 continuously contact and separate from the joint position of the horn body 5. When the contacts 13 contact the horn body 5, the horn body 5 is connected to the circuit and the horn body 5 sounds. When the contacts 13 separate from the horn body 5, the horn body 5 is disconnected from the circuit and the horn body 5 does not sound, simulating the work of a person on the horn body 5 and detecting the durability of the horn body 5.

[0039] Although the present invention 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 perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
