Semiconductor device package and acoustic device including the same
A wireless earphone comprises a battery, a speaker and a chamber/space. The battery has a first surface, a second surface opposite the first surface, and a third surface extended between the first surface and the second surface. The battery is disconnected from any protecting circuits. The speaker is disposed adjacent to the first surface of the battery. The chamber/space is defined by the battery and the speaker. The chamber/space is devoid of any electronic component.
1. A wireless earphone, comprising:
a semiconductor device package;
a battery, wherein the semiconductor device package and the battery are arranged along a first axis of the wireless earphone;
a speaker, wherein the battery and the speaker are arranged along a second axis of the wireless earphone substantially perpendicular to the first axis; and
a housing encapsulating the semiconductor device package, the battery, and the speaker;
wherein the battery has a planar surface and a curved surface, wherein the planar surface faces the speaker;
wherein the semiconductor device package is disposed over the curved surface of the battery and the speaker is disposed over the planar surface of the battery;
wherein the housing has a first surface extending upwardly from an end of the wireless earphone configured to be plugged into an ear canal to a top end of the housing and a second surface extending downwardly from the end of the wireless earphone to a bottom end of the housing;
wherein a first slope of the first surface of the housing is higher than a second slope of the second surface of the housing;
wherein a first curvature of the first surface of the housing is different from a second curvature of the second surface of the housing;
wherein the semiconductor device package is disposed in a first space of the housing, wherein the speaker and the battery are disposed in a second space of the housing different from the first space, and wherein the first surface of the housing overlaps the first space and the second space in a direction along the second axis; and
wherein the second surface of the housing overlaps the second space but does not overlap the first space in the direction along the second axis.
2. The wireless earphone of claim 1 , wherein the speaker is disposed between the planar surface of the battery and the end of the wireless earphone configured to be plugged into the ear canal.
3. The wireless earphone of claim 2 , wherein a projection of the speaker on the battery along the second axis is entirely within the planar surface of the battery.
4. The wireless earphone of claim 3 , wherein the semiconductor device package and the planar surface of the battery are not overlapped along the first axis and the second axis.
5. The wireless earphone of claim 1 , wherein when the end of the wireless earphone is plugged into the ear canal, the semiconductor device package is higher than the end of the wireless earphone.
6. The wireless earphone of claim 5 , wherein when the end of the wireless earphone is plugged into the ear canal, the semiconductor device package is higher than the ear canal.
7. The wireless earphone of claim 6 , wherein when the end of the wireless earphone is plugged into the ear canal, the semiconductor device package is disposed around a location between the ear canal and an ear helix.
8. The wireless earphone of claim 1 , wherein when the wireless earphone is worn on an ear, a projection of the semiconductor device package on the ear and a projection of the battery on the ear are not overlapped.
9. The wireless earphone of claim 1 ,
wherein the semiconductor device package is entirely in the first space of the housing;
wherein the speaker and the battery are entirely in the second space of the housing; and
wherein the end of the wireless earphone configured to be plugged into the ear canal is in the second space of the housing.
