Description

A bone conduction vibrator with electrode bottom wiring

Technical areas:

The utility model relates to the technical field of earphone products, in particular to a bone conduction vibrator with electrode bottom connections and a bone conduction earphone.

Background technique:

Bone conduction headphones usually include two headphone bodies and a back-hanging component that connects the two headphone bodies. The main body of the earphone includes an earhook component and a movement part that are fixedly connected together. The movement part is the core component of the bone conduction earphone and needs to be in contact with the skin surface of the user's head during use. A bone conduction vibrator is installed inside the movement, and the bone conduction vibrator generates bone conduction sound in the skin contact area of the headphone body.

The working principle of the bone conduction vibrator is: after the audio signal is converted into an electrical signal, it is transmitted to the bone conduction vibrator through the connecting wire, thereby driving the vibrator mechanism in the bone conduction vibrator to produce corresponding vibrations. The electrode end of the bone conduction vibrator and the external connecting wire need to be electrically connected through welding, as shown in Figure 1. The usually used method is: the electrode 41 is led out from the bone conduction vibrator 4. The electrode 41 is formed by the bone conduction vibrator. 4 is extended into the front cavity, and then the electrode 41 and the external connection wire 43 are welded. During welding, in order to connect the connecting wire 43 to the electrode 41, a wire groove 42 needs to be opened on the surface of the cover 40 constituting the front cavity, and the connecting wire 43 passes through the wire groove 42. The shortcomings of this solution are:

1. In order to seal the wire trough, it is usually necessary to inject sealant into the wire trough 42, which may easily cause glue leakage and cause high-frequency failure of the vibrator mechanism.

2. When the amount of sealant is reduced to avoid injecting too much sealant, poor sealing will occur.

3. Even if sealant is injected into the wire trough, the seal may not be tight enough, leading to water intrusion.

4. In bone conduction earphones, when the entire bone conduction vibrator is connected to the earhook assembly, the earhook assembly is usually connected to the back of the bone conduction vibrator. In this way, the connecting wire 43 must be bypassed from the side of the cover 40, causing the connection Line 43 is longer and causes greater energy loss.

Based on the above reasons, the inventor proposes the following technical solutions.
