Description

Technical Field

[0001] This utility model relates to the field of animal experimental facilities technology, and in particular to a portable vocalization intervention device for animal experiments. Background Technology

[0002] In clinical and basic research on noise-induced hearing loss, animal experiments are required. After auditory electrophysiological assessment of subjects such as guinea pigs, rats, and mice, different noise stimuli are used according to different experimental purposes (the sound signal needs to be quantified and evaluated). Subsequently, the subjects (or after appropriate treatment) are subjected to quantitative and qualitative detection and observation of relevant indicators to obtain relatively objective statistical results.

[0003] However, most traditional animal experimental vocalization intervention devices currently use a soundproof enclosure to cover a stereotactic injection device. The speaker of the vocalization intervention device is placed inside the soundproof enclosure through a pre-reserved opening to produce sound. The speaker is usually fixed inside the box formed by the soundproof enclosure. When the box is sealed, the position of the speaker cannot be changed, and it is impossible to test the experimental animals' response to sound intervention in the case of sound sources from different directions.

[0034] Among them, such as Figure 3 As shown, the upper end of the enclosure 1 has at least two installation spaces 103, and each installation space 103 is provided with a sound insulation strip 2.

[0037] Among them, such as Figure 5 As shown, the mounting groove 202 is provided with a magnetic component 203 inside, and the fixing component 301 is provided with a magnetic metal corresponding to the magnetic component 203 inside; the magnetic component 203 increases the stability of the connection between the fixing component 301 and the sound insulation strip 2.

[0038] Among them, such as Figure 2 As shown, the sealing member 204 is made of flexible sound insulation material, and the upper end of the sealing member 204 is provided with a handle; by sealing the unused mounting groove 202 on the sound insulation strip 2 through the sealing member 204, sound is prevented from passing through the mounting groove 202, thus ensuring the sound insulation performance of the enclosure 1.

[0039] Among them, such as Figure 1 As shown, it also includes a base plate 101 and a connector 102; the base plate 101 is connected to the bottom of the housing 1 through the connector 102; both the base plate 101 and the housing 1 are modular structures, and each module is fixedly assembled together through the connector 102; by using the connector 102 as a base, the various modules of the base plate 101 and the housing 1 are assembled and spliced ​​together, so that the whole device is detachable and easy to carry.
