Abstract
The utility model discloses a kind of high-strength solderless and damage audio amplifier, comprise case lid and block, described case lid and block fasten mutually with step surface, the inside sidewalls face of block or case lid is provided with lead-in, the step surface of this lead-in and block or case lid forms bayonet socket, and lead-in is arranged along the interval, length of side direction of block or case lid sidewall.Adopt high-strength solderless of the present utility model to damage audio amplifier and can improve loudspeaker box structure intensity, be welded to connect rear good looking appearance, solderless is damaged.
Description
Technical field
The utility model relates to loudspeaker techniques field, particularly relates to a kind of body structure of plastic loudspeaker box.
Background technology
Sound box is the weight part of speaker products, and it all plays a part very large to the tonequality, cost etc. of speaker products, and according to the difference of audio amplifier, sound box also has a lot of materials and version, and plastics are one of novel audio amplifier materials.Plastic loudspeaker box mostly outward appearance is magnificent, and the price of relative moderate, allow again them firmly occupy the market of mini audio amplifier, active multimedia loudspeaker boxes and even many outdoor sound equipments.Also to attract manyly youthfully to like.
Plastic loudspeaker box casing usually to be interlocked with block two parts by case lid and to be connected by ultrasonic bonding and shape is in aggregates, the common structure of the part that interlocks is falcon access node structure, namely on the connecting end surface of block and case lid sidewall, falcon groove and convex falcon is had, the casing that such structure is formed needs thicker sidewall thickness, otherwise residual wall thickness is thinner after wall box opens falcon groove, easily produce distortion, damaged after welding, weld mark obviously, weldering damages serious, produces have a strong impact on outward appearance; Thicker wall thickness adds production cost, and wall box open falcon groove after residual wall thickness still relatively thin, have impact on structural strength, actual bonding strength is not high.
Utility model content
For the above-mentioned deficiency existing for prior art, technical problem to be solved in the utility model is to provide a kind of high-strength solderless and damages audio amplifier, and it can improve loudspeaker box structure intensity, is welded to connect rear good looking appearance, solderless is damaged.
In order to solve the problems of the technologies described above, the high-strength solderless of one of the present utility model damages audio amplifier, comprise case lid and block, described case lid and block fasten mutually with step surface, the inside sidewalls face of block or case lid is provided with lead-in, the step surface of this lead-in and block or case lid forms bayonet socket, and lead-in is arranged along the interval, length of side direction of block or case lid sidewall.
In said structure, because described case lid and block fasten mutually with step surface, the inside sidewalls face of block or case lid is provided with lead-in, the step surface of this lead-in and block or case lid forms bayonet socket, then case lid and block are made rightabout step surface and are mutually fastened, and form bayonet socket with lead-in, make correctly to be located between case lid and block, compared with conventional falcon access node structure, step surface fastens and casing wall thickness is divided into two parts, and falcon access node structure is divided into three parts, when equal casing wall thickness, the thickness of every part obviously increases, structural strength is got a promotion and guarantee, also make welding quality get a promotion simultaneously, thickness increases, intensity is not yielding after ensureing, more not cracky, presentation quality is guaranteed, otherwise when each segment thickness meets requirement of strength, casing wall thickness just can reduce, thus can reduce product cost, again because the length of side direction interval of lead-in along block or case lid sidewall is arranged, then lead-in is without the need to arranging in whole wall box length of side direction, both necessary bayonet arrangement had been defined, ensure that the location between case lid and block, ensure that product quality, also save the material that casing is used, improve economic benefit.
A kind of preferred implementation of the present utility model, described lead-in is the list structure arranged along block or case lid Sidewall Height direction.Adopt this execution mode, both can form bayonet socket and save material, plastic products may be met again and produce releasing process requirement.
Another kind of preferred implementation of the present utility model, is provided with lead-in in the inside sidewalls face of block, and the step surface of this lead-in and block forms bayonet socket.Adopt this execution mode, lead-in is provided with on block, and the projection of case lid step surface is connected to block and appears on the stage in bayonet socket that terrace and lead-in formed, meets the requirement that case lid and block fasten mutually with step surface.
Another preferred implementation of the present utility model, is provided with lead-in in the inside sidewalls face of case lid, and the step surface of this lead-in and case lid forms bayonet socket.Adopt this execution mode, lead-in is provided with on case lid, and the projection of block step surface is connected to case lid and appears on the stage in bayonet socket that terrace and lead-in formed, meets the requirement that case lid and block fasten mutually with step surface equally.
The further preferred implementation of the utility model, the step surface of described block or case lid is provided with rib.Adopt this execution mode, arranging when can make ultrasonic bonding between case lid and block of rib reaches better welding quality.
Another further preferred implementation of the utility model, described rib cross section is triangular in shape.Adopt this execution mode, leg-of-mutton rib is more convenient for ultrasonic bonding.
The another further preferred implementation of the utility model, the sidewall apical side height of the end face of described lead-in and block or case lid is unanimous on the whole.Adopt this execution mode, the bayonet socket degree of depth that lead-in and case lid or block step surface can be made to be formed reaches maximum, thus ensures to be welded to connect quality.
Accompanying drawing explanation
Damage audio amplifier below in conjunction with the drawings and specific embodiments to the high-strength solderless of the utility model to be described in further detail.
Fig. 1 is the structural representation that the high-strength solderless of the utility model damages a kind of specific embodiment of audio amplifier;
Fig. 2 is the vertical view removing lid section in structure shown in Fig. 1;
Fig. 3 is that in structure shown in Fig. 1, case lid combines with block the enlarged diagram at position.
In figure: 1-case lid, 2-block, 3-lead-in, 4-step surface, 5-rib.
Embodiment
High-strength solderless shown in Fig. 1 to Fig. 3 is damaged in audio amplifier, sound box is cuboid, the case lid 1 of composition sound box is injection molding with block 2, block 2 is the mount pad installing loud speaker, have the loud speaker installing hole in kidney ellipsoid in block 2 bottom surface, be arranged at intervals with several supporting rib stiffener in case lid 1 block 2 inside sidewalls; Case lid 1 and block 2 fasten mutually with step surface 4, the inside sidewalls face of block 2 is provided with lead-in 3, this lead-in 3 is the list structure arranged along block 2 or case lid 1 Sidewall Height direction, and lead-in 3 forms bayonet socket with the step surface 4 of block 2, and the sidewall apical side height of its end face and block 2 is unanimous on the whole.Lead-in 3 is arranged along the interval, length of side direction of block 2 sidewall; The step surface 4 of block 2 is provided with rib 5, and bottom the bayonet socket that the step surface 4 that rib 5 is positioned at lead-in 3 and block 2 is formed, rib 5 cross section is triangular in shape.
