Technical field

The utility model relates to field of acoustics, and in particular to a kind of horn testing device.

Background technique

During the manufacturing of consumption electronic product, acoustic barrier case is set for the professional acoustics of audio-frequency test It is standby, a stable sound field is provided for test, while possessing preferable sound insulation capabilities, therefore be tested loudspeaker in shielded box Powering on just becomes a potential problem；When shielded box is closed, inside can not be operated, if shielded box is opened It with manual operation, not only wastes time to reduce testing efficiency, but also there may be security risks；Whole process must assure that contact Precisely, high reliablity, and integrated testability efficiency cannot be influenced.

Summary of the invention

The purpose of this utility model is that designing a kind of horn testing device, testing efficiency is substantially increased.

To achieve the above object, the utility model provides the following technical solutions: a kind of horn testing device, including bracket, The station for putting tested loudspeaker is provided on the bracket, meanwhile, it further include powering on mould group and lower die group, wherein The lower die group includes the first cylinder being set on bracket and the pressure head connecting with the first cylinder output, meanwhile, institute Stating and powering on mould group includes the connecting plate connecting with shielded box, the second cylinder and the probe connecting with the second cylinder output.

Further, the bracket includes three layers, wherein the station and powers on mould group and is located at the bottom, the pressure head It is set to middle layer, meanwhile, first cylinder is located at top layer.

Further, the station is indent cavity configuration.

Further, the distance between the bottom and middle layer are greater than the distance between middle layer and top layer.

Further, the contact surface between the pressure head and loudspeaker is provided with cushion.

Further, it is also connected with a brace between the top layer and the bottom of the bracket, to increase the stabilization of bracket Property.

Further, the mould group that powers on further includes the dustproof cover that half wraps internal component.

The device working principle are as follows: after tested loudspeaker are put into, by switch button, control the first cylinder and drive lower die Downwards, pressure head presses to tested loudspeaker to group；After completing above-mentioned movement, then passes through the second cylinder of control and drive the spy powered on before mould group Needle contacts the position to take power of tested loudspeaker, completes a power up；After being completed, mould is powered on by the driving of the second cylinder Group probe powers off loudspeaker, then horn pressure is completed a test process, then repeated above by the first cylinder deactivation pressure head Process.

Utility model has the advantages that

1, the horn testing device uses modularized design, structure novel, and test performance is stablized, convenient for operation；Take electric portion Divide and contacted using probe, not only high reliablity, but also power good is easy to plug, while using automation skill in whole device Art, the personnel that do not need carry out internal operation, and the device meets same category loudspeaker and takes electric requirement, versatile, and significantly Improve testing efficiency.
