[0001] The utility model relates to the field of loudspeaker detection, in particular to a loudspeaker detection device. Background Art

[0002] Coaxial speakers are an important part of the audio system, and their adhesive bonding effect directly affects the sound quality and service life. If the glue is unevenly applied or the bonding is not firm, it may cause noise, distortion and other problems during the use of the speaker, and even affect the performance of the entire audio system in serious cases. Therefore, the adhesive bonding effect needs to be strictly tested and controlled during the production process to ensure the quality and reliability of the speaker. Utility Model Content

[0003] In view of this, an object of the present utility model is to provide a loudspeaker detection device, which can quickly and accurately measure the bonding effect of the bonding point of the coaxial loudspeaker.

[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a speaker detection device, including a detection platform and an electric control box, a speaker placement base is arranged on the detection platform, a clamping mechanism is arranged directly above the speaker placement base, the clamping mechanism is used to clamp the glued bonding part of the speaker, and a magnetic induction element is also arranged next to the clamping mechanism, and the clamping mechanism and the magnetic induction element are respectively connected to the core control unit of the electric control box.

[0005] When the utility model is used, the speaker to be tested is placed on the speaker placement base, and then the pressing mechanism is used to press the glue-coated bonding part of the speaker. When the bonding part of the speaker is deformed or relatively displaced due to the pressing, it will cause a change in the magnetic field. The magnetic field change is sensed by the magnetic induction element to judge the bonding effect of the speaker bonding part, and the bonding effect detection of the coaxial speaker bonding point can be realized quickly and accurately.

[0006] Furthermore, the speaker detection device also has a marking mechanism, which is connected to the core control unit of the electric control box. The marking mechanism is arranged relative to the speaker placement base and is used to mark the speakers that have passed the inspection.

[0007] Furthermore, the speaker detection device also includes a buzzer, which is connected to the core control unit of the electric control box. When it is detected that the bonding part of the speaker is unqualified, the buzzer sends out an alarm signal.

[0008] Furthermore, a speaker fixing mechanism is provided on the speaker placement base, and the fixing mechanism includes a fixing slot provided on the speaker placement base and a fixing block matching the fixing slot, and the fixing slot is provided along the four sides of the speaker placement base. When in use, the speaker is placed on the speaker placement base, and then the fixing block is inserted into the fixing slot to prevent the speaker from moving in the horizontal direction, thereby fixing the speaker.

[0009] Furthermore, the clamping mechanism includes a clamping cylinder, a pressure plate and a pressure head. The pressure plate is fixedly arranged at the output end of the compression cylinder, and the pressure head is separately arranged. When measuring, the pressure head is placed on the glue bonding part of the speaker to be tested, and the compression cylinder drives the pressure plate to apply pressure to the pressure head, thereby achieving the clamping of the glue bonding part of the speaker to be tested.

[0010] Furthermore, the clamping mechanism is further provided with a guide rod, which is arranged in parallel with the clamping cylinder, and passes through the clamping cylinder mounting cross plate. There are two groups of guide rods, which are relatively arranged on both sides of the clamping cylinder. The lower end of each group of guide rods is fixedly connected to the clamping plate, and the upper end of each group of guide rods is fixedly connected via a connecting rod. Through the action of the guide rod, the clamping plate can be stably moved and clamped.

[0011] Beneficial effects of the utility model: The utility model provides a speaker detection device, which can quickly and accurately measure the bonding effect of the coaxial speaker bonding point. When in use, the speaker to be tested is placed on the speaker placement base, and then the speaker glue bonding part is pressed by a pressing mechanism. When the speaker bonding part is deformed or relatively displaced due to the pressing, it will cause a change in the magnetic field.
