Description
Technical Field
The invention belongs to the technical field of sensors and earphone equipment, and particularly relates to a bone conduction loudspeaker protection structure, a bone conduction device and a bone conduction earphone.
Background
Bone conduction is a sound conduction mode, that is, sound is converted into mechanical vibration, and sound waves are transmitted through the skull, the bone labyrinth, the lymph fluid of the inner ear, the spiral organ and the auditory center of a human body. A bone conduction speaker is a transducer device that converts an electrical signal converted from sound into mechanical vibration.
The bone conduction speaker includes a stator, a mover, and a coil and a permanent magnet between the stator and the mover, wherein the mover is suspended on the stator and is movable relative to the stator. During operation of the bone conduction speaker, a current signal (generally, an alternating current signal) converted from sound is applied to the coil, and the magnetic field of the permanent magnet generates an ampere force on the energized coil, which causes the mover to vibrate in a vibration direction relative to the stator and generate an amplitude. Such bone conduction speakers are capable of vibrating skeletal structures of a listener (e.g., portions of a human skull) to provide a perceptible audio signal via the inner ear.
However, in practical use, when a bone conduction speaker is subjected to a large impact, the bone conduction speaker is easily damaged, and the sound quality is deteriorated.
Disclosure of Invention
The present invention is made based on the recognition and study of the following problems by the inventors:
the inventor has found through research that the bone conduction speaker is easily damaged when being subjected to a large impact, as follows:
in practice, the bone conduction speaker is usually mounted in a housing to transmit vibrations generated by the bone conduction speaker to the housing, and to transmit the vibrations to a listener via the housing. In order to prevent the mover from generating abnormal noise when the mover touches the housing during operation and to ensure stable operation of the mover, a vibration space for the mover to vibrate is generally reserved in the housing. In the prior art, the length of a vibration space in the vibration direction is often larger than the maximum amplitude of the rotor (the maximum amplitude is the maximum amplitude for ensuring the normal vibration of the rotor), when the amplitude of the rotor exceeds the maximum amplitude, the rotor is damaged, and the maximum amplitude is larger than the amplitude generated in the working process of the bone conduction loudspeaker), so that the rotor is prevented from touching the shell in the working process and the stable working of the rotor is ensured. Therefore, the displacement generated by the vibration of the mover when the mover is subjected to large impact has an opportunity to exceed the maximum amplitude of the mover, so that the mover is damaged, and the sound quality of the bone conduction speaker is deteriorated.
Therefore, a bone conduction speaker protection structure is needed.
Technical problem to be solved
In view of the problems in the art described above, the present invention is at least partially addressed. To this end, a first object of the present invention is to provide a bone conduction speaker protection structure. The rotor assembly is protected, and the service life of the bone conduction loudspeaker is prolonged.

A third object of the present invention is to provide a bone conduction headset having the above bone conduction speaker protection mechanism or the above bone conduction device.

During operation of the bone conduction speaker 1, the mover 11 vibrates in the vibration direction to generate an operating amplitude, and a maximum operating amplitude exists in the operating amplitude, and the maximum operating amplitude of the mover 11 is smaller than the maximum amplitude of the mover 11. When the mover 11 is in a vibration state under a stress (for example, the mover 11 is in a working process), and the mover 11 is not under the stress, the mover assembly 11 is stationary relative to the bone conduction speaker 1, and the mover 11 is in a balance state.
The bone conduction speaker protection structure comprises a fixed plate 21 arranged in the vibration direction of the mover 11, a limiting portion 22 arranged corresponding to the mover 11 is arranged on the fixed plate 21, and when the mover 11 moves to contact the limiting portion 22, the limiting portion 22 blocks the mover 11 to continue moving to the limiting portion 22.

By using the soft part as the limiting part, the displacement of the rotor is limited, and the impact force is greatly reduced due to the buffering characteristic of the soft part when the rotor touches the soft part, and abnormal sound which can be recognized by common human ears can not be generated due to the collision of the rotor and the limiting part.

The limiting part and the electronic module 3 arranged in this way can prevent the circuit board 31 and the electronic component 32 on the circuit board 31 from being damaged by the impact of the mover. Further preferably, a gap exists between the electronic module 3 and the limiting part 22; in this way, the force applied to the stopper 22 by the mover 11 is prevented from being transmitted to the circuit board 31 and the electronic component 32 on the circuit board 31, and the circuit board 31 and the electronic component 32 on the circuit board 31 are further protected from the mover.

It is contemplated that the support post 228 and the fixed plate 21 are separate pieces, and the first end of the support post 228 is glued to the fixed plate 21, so that the support post 228 and the fixed plate 21 can be fixedly connected.
The rest of the process is the same as that of embodiment 1, and the description thereof is omitted.
Example 7
As shown in fig. 14 and 15, the present embodiment is mainly different from embodiment 6 in that another alternative manner of the position restricting portion 22 is provided to replace the supporting column 228 fixed to the fixing plate 21 in embodiment 6 as the position restricting portion 22. The method specifically comprises the following steps: the implementation form of the position limiting part 22 includes a supporting column 228 disposed on the circuit board 31, a first end of the supporting column 228 is connected to the circuit board 31, a second end of the supporting column 228 is a free end and faces the mover 11, and when the position limiting part 22 blocks the mover 11 from further moving distally, the mover 11 moves to contact the second end of the supporting column 228.
The rest of the process is the same as that of example 6, and the description thereof is omitted.
It should be understood that the above description of specific embodiments of the present invention is only for the purpose of illustrating the technical lines and features of the present invention, and is intended to enable those skilled in the art to understand the contents of the present invention and to implement the present invention, but the present invention is not limited to the above specific embodiments. It is intended that all such changes and modifications as fall within the scope of the appended claims be embraced therein.
