Description
Technical field
The utility model relates to a kind of telephone receiver structure
,belong to the electroacoustic component of communication, information system.
Background technology
Receiver is widely used on the meanss of communication such as mobile phone, along with the raising of client to electroacoustic performance requirement, common product structure can not meet client to highly sensitive requirement and reliability product trend, the assembling of the voice coil loudspeaker voice coil lead-out wire of tradition receiver is to be bonded on vibrating diaphragm, the glue that covers of vibrating diaphragm has certain influence to product acoustic characteristic, and when mounted, bonding voice coil loudspeaker voice coil can only be installed together with vibrating diaphragm, therefore the concentricity that is difficult to adjust voice coil loudspeaker voice coil and magnet steel, the sensitivity of receiver is poor.
Summary of the invention
It is a kind of highly sensitive that the purpose of this utility model is to provide, the receiver of good reliability.
In order to achieve the above object, the technical solution of the utility model is: a kind of receiver, comprise basin frame, upper cover, magnetic circuit assembly, voice coil loudspeaker voice coil, vibrating diaphragm and two conducting strips, in basin frame, be provided with installation chamber, upper cover is fixedly connected with one end of basin frame, it is indoor that magnetic circuit assembly is positioned at installation cavity, voice coil loudspeaker voice coil is arranged on magnetic circuit assembly periphery, and be fixedly connected with basin frame, vibrating diaphragm is fitted on basin frame by upper cover, magnetic circuit assembly comprises and is fixedly connected with integral magnetic bowl, magnet steel and pole piece, two conducting strips are fixedly connected on respectively on basin frame, and it is indoor that one end of conducting strip is positioned at installation cavity, the other end stretches out outside basin frame, the boss of stretching in the inwall of described basin frame has, one end of conducting strip is positioned on boss, and two lead-out wires of voice coil loudspeaker voice coil are fixedly connected with one end of corresponding conducting strip respectively.
The both sides of described magnetic bowl all have flange, and the both sides of flange all have breach.
The surrounding of described basin frame is provided with four joint pins, and upper cover and four joint pins clamp.
Two lead-out wires of described voice coil loudspeaker voice coil and one end of conducting strip are bonding.
Adopt after said structure, the boss of stretching in having due to the inwall of basin frame, one end of conducting strip just can be positioned on boss, two lead-out wires of voice coil loudspeaker voice coil are fixedly connected with one end of corresponding conducting strip respectively, therefore directly lead-out wire are bonded on vibrating diaphragm with respect to prior art, have not only improved the reliability of installing, do not affect the vibration of membrane of shaking, and can first voice coil loudspeaker voice coil be arranged on when mounted to magnet steel periphery, and adjust at any time the concentricity of voice coil loudspeaker voice coil and magnet steel, improve sensitivity of the present utility model.
Brief description of the drawings
Fig. 1 is structure cutaway view of the present utility model;
Fig. 2 is the explosive view of Fig. 1.
Embodiment
The embodiment providing below in conjunction with accompanying drawing is described in further detail the utility model.
Referring to Fig. 1, shown in 2, a kind of receiver, comprise basin frame 1, upper cover 2, magnetic circuit assembly 10, voice coil loudspeaker voice coil 5, vibrating diaphragm 7 and two conducting strips 8, in basin frame 1, be provided with chamber 1-1 is installed, upper cover 2 is fixedly connected with one end of basin frame 1, magnetic circuit assembly 10 is positioned at installs chamber 1-1, voice coil loudspeaker voice coil 5 is arranged on magnetic circuit assembly 10 peripheries, and be fixedly connected with basin frame 1, vibrating diaphragm 7 is fitted on basin frame 1 by upper cover 2, magnetic circuit assembly 10 comprises and is fixedly connected with integral magnetic bowl 3, magnet steel 4 and pole piece 6, two conducting strips 8 are fixedly connected on respectively on basin frame 1, and one end of conducting strip 8 is positioned at installs chamber 1-1, the other end stretches out outside basin frame 1, the boss 1-2 stretching in the inwall of described basin frame 1 has, one end of conducting strip 8 is positioned on boss 1-2, and two lead-out wire 5-1 of voice coil loudspeaker voice coil 5 are fixedly connected with one end of corresponding conducting strip 8 respectively.
Shown in Fig. 1,2, in order to dodge the boss 1-2 of inwall of basin frame 1, and make mounting structure compactness, the both sides of described magnetic bowl 3 all have flange 3-1, and the both sides of flange 3-1 all have breach 3-2.
