Problems solved by technology

[0003] The bone conduction vibrator contains shrapnel used to transmit vibration. The existing shrapnel structures have various designs, but there are the following problems: 1. The hardness is high, which affects the vibration frequency, which is not conducive to sound amplification and affects the sound quality; 2. The structure is unstable and cannot be fixed. The shell forms a suspension structure with the transducer device; 3. The structure is complex and the volume is large, which is not conducive to the miniaturization design of the vibrator

Embodiment 1

[0053] Refer to attached figure 1Shown is the structure schematic diagram of the shrapnel with double missile arm structure of the present invention in the first embodiment. In this embodiment, the shrapnel 1 is designed as a circular sheet structure as a whole, including: a circular and concentric inner ring 11 and the outer ring 12, the inner ring 11 and the outer ring 12 are connected by double missile arms 13. The difference between the outer diameter and the inner diameter of the inner ring 11 is greater than the difference between the outer diameter and the inner diameter of the outer ring 12 , as shown in the figure, the inner ring 11 is wider than the outer ring 12 . Preferably, the difference between the outer diameter and the inner diameter of the inner ring 11 is at least twice the difference between the outer diameter and the inner diameter of the outer ring 12, and the optimal value is 2.5 times or 3 times, depending on the size of the vibrator, Then the size of ...

Embodiment 2

[0057] Refer to attached figure 2 Shown is a schematic structural diagram of the shrapnel with a double missile arm structure in the second embodiment of the present invention. In this embodiment, the shrapnel 1 is designed as a circular thin sheet structure as a whole, including: a circular and concentric inner ring 11 and the outer ring 12, the inner ring 11 and the outer ring 12 are connected by two double missile arms 13a, 13b, the two double missile arms 13a, 13b have the same structure, and both include: the first bomb The arm 131, the second elastic arm 132, the first connecting piece 133, the second connecting piece 134 and the third connecting piece 135, the first elastic arm 131 and the second elastic arm 132 are both arranged in a circular arc structure, And all have the same circle center as the inner ring 11, with figure 2 The two double missile arms 13a, 13b shown in are randomly arranged between the inner ring 11 and the outer ring 12, preferably, in practice...

Embodiment 3

[0061] Refer to attached image 3 Shown is the structure schematic diagram of the shrapnel with double missile arm structure of the present invention in the third embodiment. In this embodiment, the shrapnel 1 is designed as a circular sheet structure as a whole, including: a circular and concentric inner ring 11 and the outer ring 12, the inner ring 11 and the outer ring 12 are connected by a double missile arm 13, and the double missile arm 13 includes: a first elastic arm 131, a second elastic arm 132, a first connecting piece 133 , the second connecting piece 134 and the third connecting piece 135 , the first elastic arm 131 and the second elastic arm 132 are both arranged in a circular arc structure, and both are concentric with the inner ring 11 . The arc value of the first elastic arm 131 is equal to the arc value of the second elastic arm 132 . The figure shows that the radian value of the first elastic arm 131 and the arc value of the second elastic arm 132 are both ...

Abstract

The invention discloses an elastic piece with a double-missile-arm structure, a bone conduction vibrator and an assembling method thereof.The elastic piece comprises an inner ring and an outer ring which are concentric, the inner ring and the outer ring are connected through double missile arms, and the double missile arms comprise a first missile arm and a second missile arm; the first elastic arm is an arc concentric with the inner ring, one end of the first elastic arm is connected with the inner ring through a first connecting piece, the second elastic arm is an arc concentric with the inner ring, one end of the second elastic arm is connected with the other end of the first elastic arm through a second connecting piece, and the other end of the second elastic arm is connected with the outer ring through a third connecting piece. The arc radius of the second elastic arm is larger than that of the first elastic arm. The radian value of the first elastic arm is equal to that of the second elastic arm. Through the elastic sheet design of the double-missile-arm structure, the stability and elasticity of elastic sheet assembly are improved, the elasticity of the elastic sheet is increased, the high-frequency vibration frequency is achieved, and the sound quality is improved.

Description

【Technical field】 [0001] The invention relates to the technical field of bone conduction vibrator structure design, in particular to a shrapnel with a double missile arm structure, a bone conduction vibrator and an assembly method thereof. 【Background technique】 [0002] Bone conduction vibrator is a device used in earphones, hearing aids and other products to conduct sound. By converting sound source signals (such as electrical signals, etc.) into mechanical vibrations, and amplifying the vibrations, the sound can be transmitted to human bones or voices Zoom in on the player. [0003] The bone conduction vibrator contains shrapnel used to transmit vibration. The existing shrapnel structures have various designs, but there are the following problems: 1. The hardness is high, which affects the vibration frequency, which is not conducive to sound amplification and affects the sound quality; 2. The structure is unstable and cannot be fixed. The shell forms a suspension structu...
