Abstract
A speaker module adapted to be disposed on a wearable device. The speaker module includes at least one driving unit and an enclosure. The driving unit is configured to produce sound. The enclosure contains the driving unit and has a front chamber and a rear chamber. The front chamber and the rear chamber are individually located at two opposite sides of the driving unit. The enclosure has a front opening, a first rear opening, and a second rear opening. The front opening communicates with the front chamber. The first rear opening and the second rear opening individually communicate with the rear chamber. A sum of sound outputted from the front opening, the first rear opening, and the second rear opening has directivity.
Claims18
A speaker module, adapted to be disposed on a wearable device, the speaker module comprising:
- at least one driving unit, configured to produce sound;
- and
- an enclosure, containing the at least one driving unit, having a front chamber and a rear chamber, wherein the front chamber and the rear chamber are individually located at two opposite sides of the at least one driving unit, the enclosure has a front opening, a first rear opening, and a second rear opening, the front opening communicates with the front chamber, the first rear opening and the second rear opening individually communicate with the rear chamber, and a sum of sound outputted from the front opening, the first rear opening, and the second rear opening has directivity,
- wherein the front opening and the first rear opening form a first vector towards the front opening, the front opening and the second rear opening form a second vector towards the front opening, the first rear opening and the second rear opening form a third vector towards the second rear opening, the third vector has a normal vector perpendicular to the third vector, and the first vector, the second vector, and a reverse vector of the normal vector are added to form a direction of the sum.
