DETAILED DESCRIPTION

[0032] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The preferred embodiments of the present application will be described in detail with reference to the drawings.

[0033] The present application provides a kind of earphone of clamping ear, as shown in figure Figures 1 to 4 The earphone of clamping ear includes earphone body 1, clamping connector 2 and clamping piece 3;Earphone body 1 includes shell 15, shell 15 includes front cavity shell 151 and rear cavity shell 152, and pronunciation unit 11 for pronunciation is arranged in rear cavity shell 152;Rear cavity shell 152 is connected with the first end 21 of clamping connector 2, and the second end 22 of clamping connector 2 is connected with clamping piece 3.Front cavity shell 151 is soft glue material, and rear cavity shell 152 is hard glue material;Front cavity shell 151 is integrally injection molded at the end of rear cavity shell 152 away from clamping connector 2;Rear cavity shell 152 away from clamping connector 2 is provided with sound outlet 152a, sound outlet 152a is provided with sound outlet channel 152a1 through the inside and outside of rear cavity shell 152, and sound outlet 14 is arranged on front cavity shell 151 and connected with sound outlet channel 152a1.

[0034] The periphery of sound outlet 152a is provided with first clamping edge 152a2 and first clamping groove 152a3;Second clamping edge 151a and second clamping groove 151b are arranged on the inner wall of front cavity shell 151 close to sound outlet;First clamping edge 152a2 is buckled in second clamping groove 151b, and second clamping edge 151a is buckled in first clamping groove 152a3.

[0035] The first clamping edge 152a2 is buckled in the second clamping groove 151b, the second clamping edge 151a is buckled in the first clamping groove 152a3, the first clamping edge 152a2, the first clamping groove 152a3 and the second clamping edge 151a and the second clamping groove 151b are mutually engaged, the injection molding strength between the front cavity shell 151 made of soft rubber material and the rear cavity shell 152 made of hard rubber material is improved, the injection molding yield is improved, and the shell 15 is not easy to crack and damage.

[0036] Specifically, the front cavity shell 151 is made of soft rubber material and has certain softness and elasticity, and can provide more comfortable wearing feeling when worn in the ear canal, and is not easy to hurt for a long time. The front cavity shell 151 can be made of silicone, TPU or TPE material, and the rear cavity shell 152 can be made of ABS, PC or PP material. The front cavity shell 151 and the rear cavity shell 152 can be injection molded between them by double-color injection molding process or sleeve brewing process, which will not be described in detail here.

[0037] Specifically, the second clamping edge 151a is provided with a first extension platform 151c extending perpendicularly to the axis of the sound outlet channel 152a1 on the side close to the clamping connecting piece 2; the sound outlet channel 152a1 is provided with a second extension platform 152b on the side close to the clamping connecting piece 2, and the first extension platform 151c and the second extension platform 152b are integrally injection molded. By designing the first extension platform 151c and the second extension platform 152b as a ring structure and integrally injection molding, the bonding strength between the front cavity shell 151 and the rear cavity shell 152 is further enhanced. The design of extending perpendicularly to the axis of the sound outlet channel 152a1 makes the first extension platform 151c and the second extension platform 152b support each other in the vertical direction, similar to the effect of "reinforcing ribs", which can effectively disperse and absorb external pressure and reduce the risk of deformation or cracking of the shell 15 due to external force during use.

At the same time, this width range will not make the earphone body 1 too thick and heavy, and the comfort of wearing is maintained. The width of the narrowest part of the first extension platform 151c is designed so that the first extension platform 151c can better fit with the second extension platform 152b on the side away from the clamping piece 3, reducing material waste while maintaining the lightweight design of the overall structure.

In the design of the ear-holding earphone in this scheme, the first fitting slope 151d of the inner wall of the front cavity shell 151 and the first fitting bevel 152c of the rear cavity shell 152 are integrally injection molded. This slope design can effectively increase the contact area between the two, while dispersing stress and avoiding stress concentration, improving the stability and strength of the structure. Moreover, through the way of fitting with a slope, the combination of the first fitting slope 151d and the first fitting bevel 152c can better adapt to the material flow and shrinkage characteristics during the injection molding process, reducing the gap or delamination problems caused by uneven material shrinkage, thereby improving the injection molding yield.
