Description
Technical field:
the utility model relates to the technical field of earphone products, in particular to a bone conduction vibrator and a bone conduction earphone for electrode bottom wiring.
The background technology is as follows:
bone conduction headphones generally include two headphone bodies and a rear suspension assembly connecting the two headphone bodies. The earphone body comprises an ear-hook assembly and a core part which are fixedly connected together, wherein the core part is used as a core part of the bone conduction earphone, and is required to be contacted with the skin surface of the head of a user in the use process. And a bone conduction vibrator is arranged in the movement, and the bone conduction vibrator enables a skin contact area of the earphone main body to generate bone conduction sound.
The working principle of the bone conduction vibrator is as follows: after being converted into an electric signal, the audio signal is transmitted to the bone conduction vibrator through a connecting wire, so that a vibrator mechanism in the bone conduction vibrator is driven to generate corresponding vibration. The electrode terminal of the bone conduction vibrator needs to be electrically connected with an external connecting wire in a welding mode, as shown in fig. 1, the method is generally as follows: the electrode 41 led out from the bone conduction transducer 4, the electrode 41 is inserted from the front cavity of the bone conduction transducer 4, and then the electrode 41 is welded to the external connection wire 43. In the welding, in order to connect the connection wire 43 to the electrode 41, a wire passing groove 42 needs to be opened on the surface of the cover 40 constituting the front cavity, and the connection wire 43 passes through the wire passing groove 42. The drawbacks of this solution are:
1. in order to seal the wire-passing groove, it is generally necessary to inject a sealant into the wire-passing groove 42, which is likely to cause leakage of the sealant and cause high-frequency defects of the vibrator mechanism.
2. When the amount of the sealant is reduced in order to avoid excessive injection, a problem of poor sealing occurs.
3. Even if sealant is injected into the wire passing groove, the sealing is possibly not tight, so that the problem of water inflow is caused.
4. In the bone conduction earphone, when the entire bone conduction vibrator is connected to the ear-hanging component, the ear-hanging component is usually connected to the rear side of the bone conduction vibrator, and thus the connecting wire 43 must be wound around the side of the cover 40, resulting in a longer connecting wire 43 and a larger energy loss.
For the above reasons, the present inventors have proposed the following technical solutions.
The utility model comprises the following steps:
