Abstract
A speaker module includes a casing, a speaker unit and a vibration absorber. The speaker unit has a sound cavity. The speaker unit is disposed on the casing, and the speaker unit includes a first diaphragm. The vibration absorber is disposed in the casing, and the vibration absorber has a second diaphragm. When the first diaphragm vibrates, the airflow generated by the first diaphragm drives the second diaphragm to vibrate, and the vibration direction of the second diaphragm is opposite to the vibration direction of the first diaphragm, so as to absorb the vibration generated by the first diaphragm to the casing.
Claims18
A speaker module, comprising:
- a casing, having a sound cavity;
- a speaker unit, disposed on the casing, wherein the speaker unit includes a first diaphragm;
- and
- a vibration absorber, disposed in the casing, wherein the vibration absorber has a second diaphragm;
- wherein when the first diaphragm vibrates, airflow generated by the first diaphragm drives the second diaphragm to vibrate, and a vibration direction of the second diaphragm is opposite to a vibration direction of the first diaphragm, so as to absorb the vibration generated by the first diaphragm to the casing;
- wherein the first diaphragm and the second diaphragm are arranged along a first axis, and when viewed along the first axis, the first diaphragm overlaps the second diaphragm;
- wherein the casing further includes a support structure and a bottom wall, the support structure is fixedly connected to the bottom wall, and the second diaphragm is movably connected to the support structure, wherein the support structure, the second diaphragm and the bottom wall form a chamber, and the chamber and the sound cavity do not communicate with each other.
A speaker module, comprising:
- a casing, having a sound cavity;
- a speaker unit, disposed on the casing, wherein the speaker unit includes a first diaphragm;
- and
- a vibration absorber, disposed in the casing, wherein the vibration absorber has a second diaphragm;
- wherein when the first diaphragm vibrates, airflow generated by the first diaphragm drives the second diaphragm to vibrate, and a vibration direction of the second diaphragm is opposite to a vibration direction of the first diaphragm, so as to absorb the vibration generated by the first diaphragm to the casing;
- wherein the speaker unit further includes a coil configured to drive the first diaphragm, the first diaphragm and the coil are arranged along a first axis, the first diaphragm and the second diaphragm are arranged along a second axis, and the first axis is perpendicular to the second axis, wherein when viewed along the first axis, the first diaphragm does not overlap the second diaphragm;
- wherein the casing includes a top wall and a covering member, the speaker unit is disposed on the top wall, and the covering member is fixedly connected to the top wall, wherein when viewed along the first axis, the covering member completely covers the second diaphragm;
- wherein a texture, a shape, and an elastic coefficient of the second diaphragm are equal to a texture, a shape, and an elastic coefficient of the first diaphragm.
A speaker module, comprising:
- a casing, having a sound cavity;
- a speaker unit, disposed on the casing, wherein the speaker unit includes a first diaphragm;
- and
- a vibration absorber, disposed in the casing, wherein the vibration absorber has a second diaphragm;
- wherein when the first diaphragm vibrates, airflow generated by the first diaphragm drives the second diaphragm to vibrate, and a vibration direction of the second diaphragm is opposite to a vibration direction of the first diaphragm, so as to absorb the vibration generated by the first diaphragm to the casing;
- wherein the casing includes a upper cover and a lower cover, the upper cover and the lower cover are arranged along a first axis, wherein when viewed along the first axis, the first diaphragm and the second diaphragm are staggered from each other, and the first diaphragm does not overlap the second diaphragm.
