Description

Acoustic test system for woofer

Technical Field

The utility model belongs to the technical field of loudspeaker testing, and particularly relates to an acoustic testing system for a woofer.

Background

The loudspeaker is a conversion device for converting electric energy into sound, when different voltages are transmitted to the coils, the coils generate energy to interact with the magnetic field of the magnet, the interaction causes the paper disc to vibrate, and the coils of the loudspeaker move forwards or backwards due to the fact that the voltages change at any time, so that the paper disc of the loudspeaker moves along with the movement, and the action causes the density degree of air to change to generate sound. Because consumer electronic products such as mobile phones and computers are increasingly pursued for appearance and attractive appearance, the traditional loudspeaker is exposed to influence the overall attractive appearance, and therefore, the requirement for changing the performance of the loudspeaker is put forward, and the output frequency response curve of the loudspeaker is determined by the structural sealing performance of the sound cavity part from the structural aspect, so that the detection of the tightness is necessary, and whether the design requirement is met or not is detected.

Patent document: CN215726658U, a loudspeaker leakproofness check out test set, including sealed cowling 1, closing plate 2 and elevating system 30, sealed cowling 1 sets up on the elevating system 30, closing plate 2 is located the below of sealed cowling 1 and with sealed cowling 1 sealing fit, be provided with laser sensor 4 in sealed cowling 1's the sealed chamber 3, including sealed cowling, closing plate and elevating system, the sealed cowling sets up on elevating system and is driven by elevating system and reciprocate, and the closing plate is located the below of sealed cowling, will make sealed cowling and closing plate closely laminate when elevating system drives the sealed cowling and move down, is provided with sealed chamber in the sealed cowling, when sealed cowling and closing plate closely laminate, sealed chamber will be isolated and form a totally airtight space with the external world.

The device can be further improved in the actual production and use process, because the loudspeaker is a relatively precise electronic product, when the loudspeaker is tested, workers are usually required to touch the loudspeaker body for many times by using tools or hands, so the loudspeaker body is at risk of being scratched, and because the test box is provided with the microphone, the device can not adjust the distance between the loudspeaker and the microphone, howling occurs when the distance between the microphone and the loudspeaker is relatively close, and certain damage is caused to the microphone and the loudspeaker, so the loudspeaker needs to be improved.
