Abstract
The utility model discloses a collision avoidance structure of audio amplifier box back - end face, control panel (3) of installing various knobs (4) including audio amplifier box (2) that link together and the outside, the rear end face of audio amplifier box (2) on be equipped with the anticollision piece (1) of at least three discrete distribution to plan range audio amplifier box (2) rear end face that the top of anticollision piece (1) formed highly be greater than the height of knob (4) top surface apart from audio amplifier box (2) rear end face. After the structure, the audio amplifier just can reduce the collision of the knob on the control panel with ground through crashproof contact with ground when tumbling backward more than adopting to guarantee the normal use of knob better, consequently, played effectual guard action to control panel each component on and when the audio amplifier is tumbled backward.
Description
Technical field
The utility model relates to the technical field of sound equipment, is specifically a kind of anti-collision protection structure of sound box rear end face.
Background technology
The effect of audio amplifier is that audio frequency electric energy is converted to corresponding acoustic energy, and it is radiated space, and it is the terminal of sound system, and its performance height is play key effect to the playing quality of a sound system.The audio amplifier of prior art comprises casing and is provided with the control panel of various control element, casing is made up of the procapsid linked together and back casing usually, control panel is all the back being connected to back casing usually, for loudspeaker etc. put sound components outward before procapsid.But, there is following shortcoming in this audio amplifier: owing to control panel having been installed various control element, in general, control element is arranged on the inner side of control panel, but, some knobs are normally positioned at the outside of control panel, so that people are to the various operations of audio amplifier, and in order to ensure there are enough volumes in sound box, these knobs are also protrude from control panel usually, that is beyond the end face of these knobs normally higher than audio amplifier back casing, therefore, in the handling process of audio amplifier, or when being placed in uneven ground, easily there is the phenomenon of tumbling backward in audio amplifier, like this, knob control panel protruding from back casing will directly and collision on the ground, this impulsive force will cause the distortion of knob even to damage, then the control element on control panel can not normally use, thus cause the damage of audio amplifier.
Utility model content
Technical problem to be solved in the utility model is, provides a kind of anti-collision protection structure of the sound box rear end face that can play a protective role to the knob on control panel when audio amplifier is tumbled backward.
For solving the problems of the technologies described above; the anti-collision protection structure of the sound box rear end face that the utility model provides; comprise the control panel that the sound box that links together and outside are provided with various knob; the rear end face of described sound box is provided with the anticollison block of at least three dispersion distributions, and the height of the plan range sound box rear end face of the top of anticollison block formation is greater than the height of knob end face distance sound box rear end face.
Described anticollison block and sound box are an entirety by injection moulding.
The quantity of described anticollison block is four, is distributed in four edges of sound box rear end face respectively, and following two anticollison blocks are positioned at below the lower limb of control panel, and two, top anticollison block is positioned at the top of the top edge of control panel.
The shape of described anticollison block is a part for spheroid.
After adopting above structure, the utility model compared with prior art, has following advantage:
1) owing to having set up anticollison block on sound box rear end face, contact just by anticollison block and ground when audio amplifier is tumbled backward time decreases the collision on knob on control panel and ground, thus ensure that the normal use of knob better, therefore, when audio amplifier is tumbled backward to control panel and on each element serve effective protective effect;
2) anticollison block and sound box are made an entirety by injection moulding, like this, namely decrease the connector of anticollison block and sound box, also ensure that the consistency that anticollison block is connected with sound box simultaneously;
3), after following two anticollison blocks being arranged on the below of control panel lower limb, make audio amplifier when tumbling backward, first with earth surface be anticollison block, the knob more on available protecting control panel;
4), after anticollison block is designed to a part for spheroid, makes the contact on anticollison block and ground be sphere-contact, virtually counteract a part of impulsive force, play a protective role further.
Accompanying drawing explanation
Fig. 1 is the structural representation of the anti-collision protection structure of the utility model sound box rear end face.
Fig. 2 is the left TV structure schematic diagram of Fig. 1.
Wherein: 1, anticollison block; 2, sound box; 3, control panel; 4, knob.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
From the structural representation of the anti-collision protection structure of the utility model sound box rear end face shown in Fig. 1 and Fig. 2; it comprises the control panel 3 that the sound box 2 that links together and outside are provided with various knob 4; the rear end face of described sound box 2 is provided with the anticollison block 1 of at least three dispersion distributions, and the height of plan range sound box 2 rear end face of the top of anticollison block 1 formation is greater than the height of knob 4 end face distance sound box 2 rear end face.
Described anticollison block 1 and sound box 2 are an entirety by injection moulding.
The quantity of described anticollison block 1 is four, is distributed in four edges of sound box rear end face respectively, and following two anticollison blocks 1 are positioned at below the lower limb of control panel 3, and two, top anticollison block 1 is positioned at the top of the top edge of control panel 3.
The shape of described anticollison block 1 is a part for spheroid.
When audio amplifier is tumbled backward, first with following two anticollison blocks of earth surface, by the sphere of anticollison block, slow down the impulsive force on ground, protect each control element on control panel.
The above; it is only the better feasible exemplifying embodiment of the utility model; therefore interest field of the present utility model can not namely be limited to; concerning those of ordinary skill in the art, other various corresponding changes that all utilization the technical solution of the utility model and technical conceive are made all should belong within the protection range of the utility model claim.
