Embodiment 1
[0081] Such as figure 1 As shown, the speaker used in the emergency room of the present application includes a speaker housing 100, a soft rod assembly 200, a power assembly and a control unit 500;
[0082] The loudspeaker housing 100 is a box structure for supporting and positioning the housing sound outlet 110, the sound generating unit 120, the housing positioning component 130 and the energy input component 140; the housing sound outlet 110 is positioned at The side wall of the speaker housing 100 is used to output the sound generated by the sound generating unit 120; the sound generating unit 120 is fixed inside the speaker housing 100 for emitting For the effect of the sound of the evacuation crowd, preferably, the sound generating unit 120 has a sound recording function, which is a prior art, and will not be described in detail here; the housing positioning component 130 is arranged on the speaker housing 100, It is used to wear the speaker on the person, hang it on th...
Embodiment 2
[0102] Considering that although the soft rod assembly 200 in the above-mentioned embodiment will not cause greater damage to people who do not evade in time on the passage due to its material, it will accumulate elastic potential energy when it is bent under force, and when it crosses obstacles (people on the passage) ) will release elastic potential energy (rebound), the rebound process is equivalent to doing a whipping action, which is likely to cause damage to other people in the passage; especially children in the passage may cause damage to their heads and even glasses;
[0103] In view of the above problems, the embodiment of the present application adds a rod body anti-rebound component 300 and a rod body restoration component 400 on the basis of the above embodiments to prevent the soft rod assembly 200 from rebounding rapidly after being stressed;
[0104] Specifically:
[0105] Such as Figure 6 to Figure 8 As shown, the soft rod unit 210 is a hollow rod; the rod b...
