A coaxial speaker includes a magnetic circuit system, a first sound production unit, and a second sound production unit. The first sound production unit and the second sound production unit are coaxially disposed. The first sound production unit surrounds the second sound production unit. The first sound production unit includes a first vibrating diaphragm and a first voice coil. The first voice coil is configured to drive the first vibrating diaphragm to vibrate and produce sound. The second sound production unit includes a second vibrating diaphragm and a second voice coil. The second voice coil is configured to drive the second vibrating diaphragm to vibrate and produce sound. The coaxial speaker ensures concentricity of the first vibrating diaphragm and the second vibrating diaphragm, reduces a height of related products, and reduces cost of the magnetic circuit system.

The camera decoration part includes a first plate and a second plate; a first surface of the first plate has a decoration rendering; a second through-hole corresponding to a first through-hole is disposed on the second plate; a first surface of the second plate includes a connection area and an avoidance area, where the avoidance area is formed by recessing the first surface of the second plate to a second surface of the second plate by a first depth, a thickness of the second plate is greater than or equal to a height of a protrusion on a housing of the electronic device, the first depth is greater than or equal to the height of the protrusion, and a projection of the protrusion is in a projection area of the avoidance area.

Camera decoration part, fabrication method, and electronic device

A container cover relating the technical field of smart water cups is provided. The container cover includes a cover body provided with a drinking water passage, wherein an upper side of the drinking water passage is a drinking port; a cover cap provided on an upper side of the cover body; an inner cover provided on a lower side of the cover body, wherein a water outlet connected to the drinking water passage is provided in the inner cover, and a sealed accommodation cavity is formed between the inner cover and the cover body; a cover opening transducer provided between the cover body and the cover cap; and a flow sensing transducer, an orientation transducer, a power supply module, and a control circuit board provided in the sealed accommodation cavity.

Container cover

The present invention provides a coaxial speaker including a frame, a magnetic circuit system, a first vibration system and a second vibration system fixed on different sides of the magnetic circuit system. The first vibration system locates communicated with the second vibration system. The first vibration system includes a first diaphragm and a first voice coil. The second vibration system includes a second diaphragm and a second voice coil. The magnetic circuit system includes a first magnetic gap and a second magnetic gap. The first voice coil partially locates into the first magnetic gap, the second voice coil partially locates into the second magnetic gap. The first diaphragm is used for generating bass sound, the second diaphragm is used for generating treble sound. A sound hole is provided on the first diaphragm for emitting the treble sound. Bass sound and treble sound form a full-range speaker, which providing high-quality sound.

A method includes: sending at least two sound wave signals through a loudspeaker; receiving, through a microphone, at least two sound wave signals from a second electronic device, and determining a first receiving result of receiving the at least two sound wave signals; determining a first possible angle value between the second electronic device and a first electronic device based on the first receiving result; and receiving a second possible angle value between the first electronic device and the second electronic device that is from the second electronic device, and determining an actual angle between the first electronic device and the second electronic device based on the first possible angle value and the second possible angle value; or sending the first possible angle value to the second electronic device, and receiving an actual angle between the first electronic device and the second electronic device.

A coaxial speaker box includes a housing, a speaker, and a sound guide channel for guiding sound outside. The speaker includes a frame, a magnetic circuit system, a first vibration system, and a second vibration system. The first vibration system is disposed in the frame. The second vibration system is disposed on an outer side of the frame. A front cavity is formed among the first vibration system, the second vibration system, and the housing. The first vibration system includes a first vibrating diaphragm and a first voice coil. A coaxial full-band speaker is formed by the bass and the high pitch of the coaxial speaker box to provide high-quality sound effects. The high pitch and the bass share a side sound guide channel, and form a front cavity resonance in a bass channel to improve high-frequency sound effects.

Coaxial speaker box

The present invention provides a coaxial speaker including a frame, a magnetic circuit system, a first vibration system fixed on an inner side of the frame, and a second vibration system fixed on an outer side of the frame. The first vibration system locates coaxially with the second vibration system. The first vibration system includes a first diaphragm and a first voice coil. The second vibration system includes a second diaphragm and a second voice coil. The magnetic circuit system includes a first magnetic gap and a second magnetic gap. The first voice coil at least partially locates into the first magnetic gap, the second voice coil at least partially locates into the second magnetic gap. The first diaphragm is used for generating treble sound, and the second diaphragm is used for generating bass sound. Bass sound and treble sound form a full-range speaker, providing high-quality sound.

Disclosed is an electronic device with a sounding function, including a shell structural member and a speaker. The speaker includes a first sounding unit used to emit low-frequency sounds and a second sounding unit used to emit high-frequency sounds that are coaxially arranged. The first sounding unit surrounds the second sounding unit. The shell structural member is provided with a first channel for transmitting the low-frequency sounds, a second channel separated from the first channel for transmitting the high-frequency sounds, and a common channel for communicating both the first and second channels with the outside of the electronic device. The second channel includes a front cavity of the second sounding unit and a connecting channel for communicating the front cavity with the common channel. The connecting channel is in a horn shape. The effect of the high-frequency sounds of the electronic device with a sounding function is improved.
