Embodiment
Although the utility model allows many multi-form execution modes, but shown in the drawings and describe preferred implementation of the present utility model in detail at this, be to be understood that content of the present disclosure is regarded as the example of the utility model principle, and be not intended to wide intension of the present utility model to be limited to described execution mode.
At this, described the receiver using in the multiple application such as hearing instrument (HIs) is provided.Receiver described here can also be deployed in other equipment, such as PC and cell phone.Other example apparatus are possible.
In multiple these execution modes, provide motor and this receiver for receiver to comprise at least one magnet, magnet support structure, coil and armature.This armature comprises microscler first, microscler second portion and microscler third part.First, second portion and third part each other almost parallel are arranged.Second portion is arranged between first and third part, and can move freely and be positioned close at least one magnet.First and third part are connected to magnet support structure.Connector part and first, second portion and third part adjacency are extended part connector part below residing the first plane of second portion.
With reference now to Fig. 1-5,, a kind of example of receiver 10 has been described.Receiver 10 comprises the housing 14 that restriction is inside and outside.Receiver 10 also comprises motor 16, and this motor 16 comprises coil 18, lamination (or magnet support structure) 20 and armature 22, and this armature is arranged in fact in housing 14.The electric current of representative voice is produced and is moved by coil 18.Electric current by coil 18 moves armature 22, and it makes trundle move then, thereby causes vibrating membrane vibrations and produce the sound of expectation.Sound sends by the port in housing and subsequently by sound pipe (sound tube) 25.Armature 22 can consist of dilval.
Provide the motor for receiver 10, and receiver 10 comprises at least one magnet 101, magnet support structure, coil and armature.Armature 22 comprises microscler first 102, microscler second portion 104 and microscler third part 106.First 102, second portion 104 and third part 106 be layout parallel to each other roughly.Second portion 104 is arranged between first 102 and third part 106, and can move freely and be positioned close at least one magnet.Magnet is formed with opening in magnet support structure 20 and between magnet.Part armature 22 extends through this opening.First 102 and third part 106 are connected to magnet support structure 20.Connector part 108Yu first 102, second portion 104 and third part 106 adjacency are extended part connector part 108 below residing the first plane of second portion 104.
In some respects, second portion 104 is tapered to the second width from the first width, and this first width is greater than this second width.
In other respects, first 102 and third part 106 are arranged in the second plane.The second plane is arranged in the direction substantially vertical with the first plane.
In other example, second portion comprises protuberance 110.This protuberance is configured for and is attached to another member.In other example, second portion 10 comprises notch 112.This notch is configured to approach this coupling part.In other side, coil 18 forms passage, and second portion 104 is configured to by this passage.
At this, described preferred implementation of the present utility model, comprised known for inventor for implementing optimal mode of the present utility model.Should be understood that, illustrational execution mode is only exemplary, should not be construed the restriction to the utility model scope.
