Patented Innovations in Mobile Phone Case Designs for Sound Amplification

Mobile device case that improves audio quality, provides better drop protection and allows easy device access while reducing size and weight compared to traditional cases. The case has a unique design to redirect sound emitted from the device speakers. It has nested sound channels within the case walls that connect to a chamber around the device speaker. This guides the sound out of the case instead of just through the bottom. It also has a built-in handle strap that protrudes away from the device when wrapped around, making it easier to grip. The strap support prevents it from collapsing into the case when not in use.

A stand for mobile devices like smartphones that enables hands-free viewing at an angle while also enhancing the audio output without requiring external speakers or power sources. The stand has a V-shaped base with one leg serving as a support surface for the device's back. The other leg has an angled acoustic enhancement panel that reflects sound forward. This passively amplifies the device's internal speakers without electronics or batteries. The stand can also have a holder for a removable battery pack or solar charging cell.

A case for mobile devices that amplifies the sound output from the device's speakers and improves microphone sensitivity. The case has baffles and horns that enhance acoustics when the device is inside. The speaker baffle has a tapered opening that expands like a horn to amplify sound. The microphone baffle compresses sound waves to boost sensitivity. The case also has a stand and clip.

Protective case for electronic devices with sound-directing features to reduce interference between speakers and microphones when the device is in the case. The case has multiple sound channels that direct sound in different directions. This prevents speaker sound from blocking the microphone or vice versa when the device is inserted. The channels can have non-linear paths and offset openings to separate speaker and microphone sound paths.

A protective cell phone case is designed to redirect radiation away from the user while amplifying sound and shielding radio signals for privacy. The case has a hinged front plate with slots and a lip to fit over the phone, a copper shield with sound openings, and a back plate with a camera slot. The copper shield is concave to redirect radiation away from the user. The case also has octagonal notches and dense wood material for enhanced sound amplification.

Mobile phone with an integrated audio system that reduces environmental noise during calls. The phone has a touchscreen on the front and an audio system inside the housing. The audio system has two hollow spaces separated by a loudspeaker. Sound is emitted to the user's ear through a front opening and away from the ear through a rear opening. The sound waves from the front and rear openings are phase-shifted, so when the phone is used, the sound is mostly directed to the user's ear instead of leaking out from the rear. This avoids covering the front opening with the ear during calls like a headphone. The rear opening reduces the environmental noise picked up by the microphone.

A speaker case for protecting and enhancing the audio capabilities of a smartphone. The case has two interlocking shells, one to hold the phone and another slide-on shell with a built-in Bluetooth speaker. The speaker is wirelessly connected to the phone inside the case to provide better sound quality without needing external speakers. The case also provides impact protection for the phone.

A carrier for a portable communication device, like a radio, improves audio quality by directing sound from the device's speaker into an acoustic tunnel formed between the device screen and the carrier surface. This allows the device to be carried lower on the body while still providing good audio without increasing the volume or using external speakers. The tunnel concentrates and focuses the sound towards the user's ear. The carrier has a body with ends and a surface between them, and the device is secured to the carrier with a releasable connection. The device screen faces the carrier surface, forming the tunnel.

A detachable speaker system for portable electronic devices like smartphones that provides improved audio quality in a compact form factor. The system involves a speaker unit with expandable housing that attaches to the device using a universal fastener. This allows the speaker to be easily detached and swapped with other accessories. The expandable housing accommodates the speaker components in a compact size when attached to the device, then expands to provide better acoustics when detached. The universal fastener allows the same attachment mechanism to work with any device or case.

A collapsible smartphone speaker accessory that amplifies sound from the device when deployed. The accessory attaches to a smartphone case and can be collapsed and stored inside the case when not in use. It has a hollow tapering shape for natural sound amplification. The accessory can also transmit sound wirelessly to other devices with the same accessory. This allows multiple devices to connect and use the accessories as distributed speakers.

A case for mobile devices that improves audio quality by converting digital sound sources stored on the device to high quality analog signals. The case has a detachable audio module that connects to the device and amplifies the digital audio. This allows using a single high quality audio module with any mobile device by attaching it to the case, rather than needing separate audio devices for each device type. The module can be fixed to the case using magnets or screws.

Protective case for mobile devices that adds features like integrated speakers, wireless charging, ambient light sensors, and toggling device functions. The case has wireless interfaces like Bluetooth and WiFi, a rechargeable battery, speakers, and a microphone. It connects to the device via a sliding interface. The case can provide wireless audio, charging, and functionality when attached, without needing external peripherals.

A storage device for carrying an electronic device that amplifies and redirects sound emitted by the device when it's inside the storage device. The storage device has a projection device with a recess that reflects sound back toward the device when it's close by. The projection device can be placed inside the storage device to amplify and redirect sound emitted by the device inside the storage device. This prevents muffling or indiscernible sound when the device is in a bag or case.

Portable electronic device accessory with built-in speakers and stand for enhancing audio quality and viewing convenience. The accessory has a clip case to hold the device snugly and prevent dropping. It has a base with magnets and a pivoting support arm. The case has magnets and cutouts to attach the arm. The arm has speakers. This allows tilting the device for better viewing angles while the speakers provide high quality sound.

A protective case for tablet computers that integrates an external loudspeaker into the case. The case has a compartment to hold the tablet and a separate speaker compartment that houses the loudspeaker. This allows amplified audio playback from the tablet through the external speaker without needing an external device. It also provides protection for the tablet screen from impacts that could damage it.
