The present disclosure relates to integrated speakers in a portable computing device.
Many portable computing devices, such as laptop computers comprise loudspeakers for reproducing sound. Typically, the sizing and dimension limits of portable computing devices put certain restrictions on speaker sizing and placement.
An object of the present disclosure is to provide an improved acoustic performance of speakers of a portable computing device.
According to a first aspect of the present disclosure, there is provided a portable computing device comprising a keyboard and an acoustic transducer, the keyboard comprising a key, wherein the acoustic transducer is placed in the key, and wherein the key comprises a sound port allowing sound generated by the transducer to propagate.
By providing a sound port in the key, in which the transducer is arranged, sound generated by the transducer may be allowed to propagate, thereby improving the sound to a user. For instance, the influence of the key material, material thickness etc. on sound generated by the transducer, such as a frequency spectrum thereof, may be reduced as at least part of the sound may pass through the sound port.
According to a second aspect of the present disclosure, there is provided a portable computing device comprising an acoustic transducer and a keyboard, the keyboard comprising a key, wherein the acoustic transducer is arranged in or underneath the key, and wherein the portable computing device further comprises a grommet arranged underneath the key, whereby the grommet provides support and vibration reduction for the acoustic transducer and/or the key.
It has been realized that by providing an acoustic transducer in or underneath a key of the keyboard according to the first and/or second aspect, the limited space for acoustic transducers in portable computing device may be utilized to provide an improved sound to the user by allowing for a larger flexibility in sizing and placement of the acoustic transducers. This may, in turn, allow for an improved audio performance of such transducers or loudspeakers given the sizing and dimension limits. The audio performance may be improved in the low and/or high frequency range. By providing the transducer in the key and/or by providing a grommet supporting the transducer and/or key, a damping of a vibration force between a key and the transducer may be provided, which vibration force could reduce the sound quality from the transducer. As an example, where the transducer is provided under the key, a grommet is provided, which may dampen the transmission of a vibration force between the key and the transducer caused by a user striking the key. As another example, where the transducer is provided in the key, the transducer will follow the key movement when a user strikes this. Thereby, a vibration force between the key and transducer, which force could reduce the sound quality from the transducer, may be reduced. Where the transducer is arranged in the key and a grommet is furthermore provided, the vibration force may potentially be further dampened.
By the term “acoustic transducer” may here be understood a transducer configured to emit a sound. The transducer may, for instance, be of a moving coil type, a ceramic type, or a similar transducer type. The transducer may be configured to be a tweeter speaker or may be configured to be a full range speaker.
