Abstract

The utility model relates to a receiver device with a U-shaped armature. A motor used for a receiver is provided. The receiver includes at least one magnet, a magnet supporting structure, a coil and an armature; the armature comprises an elongated first part and an elongated second part; the first part is connected with the second part and is adjacent to a third part, and therefore, the first part and the second part are approximately parallel to each other, and the first part, the second part and the third part together form a substantially U-shaped armature.

Description

There is the receiver apparatus of U-shaped armature

Technical field

The utility model relates to receiver, and relates more particularly to the impedance component of receiver.

Background technology

Polytype microphone and receiver (transducer) are used these years.In these equipment, different electronic components are contained in housing or assembly together.For example, receiver typically comprises shell, vibrating membrane and motor, coil except other element, around axle, lamination (stack), and these elements are contained in receiver shell.The acoustic equipment of other type can comprise the element of other type.Motor typically comprises coil, yoke or lamination and armature, and these parts form magnetic circuit together.

Transducer can use in multiple application, such as hearing instrument.These equipment can use in other application, such as PC or cell phone.

As mentioned, receiver has armature.Armature is moving meter and moves in the time that electric current generates variation magnetic field in receiver.

Utility model content

According to one side of the present utility model, a kind of motor for receiver is proposed, this receiver comprises at least one magnet, magnet support structure, coil and armature, wherein this armature comprises microscler Part I and microscler Part II, Part I be connected with Part III with Part II and with Part III adjacency, make Part I and Part II almost parallel and make Part I, Part II form the roughly armature of U-shaped together with Part III each other.

Described Part I is anchored into described magnet support structure.

Described Part II can move freely and be configured to approach described at least one magnet.

Described coil forms passage, and described Part II is configured to by this passage.

Described Part II is tapered to the second width from the first width, and this first width is greater than this second width.

Described Part I is tapered to the second width from the first width, and this first width is greater than this second width.

Described Part II comprises protuberance, and this protuberance is configured for and is attached to another member.

Brief description of the drawings

In order more completely to understand the utility model, should be with reference to the detailed description and the accompanying drawings below, wherein:

Fig. 1 comprises according to the stereogram of the receiver of the utility model numerous embodiments;

Technical staff will appreciate that the element in accompanying drawing is known briefly and illustrates.Also will recognize and may describe or describe some action and/or step with specific order of occurrence, but it will be understood to those of skill in the art that actual about this specificity is sequentially unwanted.And should be appreciated that, term used herein and expression have general significance, investigate the term relevant with research field and express unanimously, unless illustrated in addition specific meaning at this to this term and expression corresponding separately.

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.

Describe the receiver using in the multiple application such as hearing instrument (HIs) is provided at this.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 the motor for receiver.This receiver comprises at least one magnet, magnet support structure, coil and armature.This armature comprises microscler Part I and microscler Part II.Part I be connected with Part II and with Part III adjacency, make Part I and Part II almost parallel and make Part I, Part II form the roughly armature of U-shaped together with Part III each other.

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.By the electric current of coil 18, armature 22 is moved, it makes trundle move then, thereby causes that vibrating membrane shakes and produce the sound of expectation.Sound sends by the port of housing and subsequently by sound pipe (sound tube).Housing 14 is formed by the top cup 14a that is attached to end cup 14b.Armature 22 is made up of dilval.

In these methods, provide the motor 16 for receiver 10.Receiver 10 comprises at least one magnet 102, magnet support structure 20, coil 18 and armature 22.Armature comprises microscler Part I 106 and microscler Part II 108.Part I be connected with Part III 110 with Part II and with Part III 110 adjacency, make Part I 106 and Part II 108 almost parallel and make Part I 106, Part II 108 form the roughly armature of U-shaped together with Part III 110 each other.

In some respects, Part I 106 is anchored into magnet support structure 20.In other respects, Part II 108 can move freely and be configured to approach at least one magnet 110.In some instances, coil 18 forms passage, and Part II 108 is configured to by this passage.

In other examples, Part II 108 is tapered to the second width from the first width.The first width is greater than the second width.In some other examples, Part I 106 is tapered to the second width from the first width.The first width is greater than the second width.

In other respects, Part II 108 comprises protuberance 112.This protuberance is configured for and is attached to another member, such as drive rod.It will be appreciated that to have at the U-shaped armature of the arrangements of elements shown in this and improved efficiency and magnetic radiation than previous design, and formed the very compact layout that is applicable to use in small-sized hearing instrument simultaneously.

Describe preferred implementation of the present utility model at this, 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.
